Fulltext In Silico and In Vitro Methods in the Characterization of Beta-Carotene as Pharmaceutical Material via Acetylcholine Esterase Inhibitory Actions

Muthuraman A, Ramesh M, Mustaffa F, Nadeem A, Nishat S, Paramakrishnan N, et al.

Molecules, 2023 May 26;28(11).
PMID: 37298835 DOI: 10.3390/molecules28114358

Molecular docking is widely used in the assessment of the therapeutic potential of pharmaceutical agents. The binding properties of beta-carotene (BC) to acetylcholine esterase (AChE) proteins were characterized using the molecular docking method. The mechanism of AChE inhibition was assessed by an experimental in vitro kinetic study. In addition, the role of BC action was tested by the zebrafish embryo toxicity test (ZFET). The results of the docking ability of BC to AChE showed significant ligand binding mode. The kinetic parameter, i.e., the low AICc value shown as the compound was the competitive type of inhibition of AChE. Further, BC also showed mild toxicity at a higher dose (2200 mg/L) in ZFET assessment with changes in biomarkers. The LC50 value of BC is 1811.94 mg/L. Acetylcholine esterase (AChE) plays a pivotal role in the hydrolysis of acetylcholine, which leads to the development of cognitive dysfunction. BC possesses the regulation of acetylcholine esterase (AChE) and acid phosphatase (AP) activity to prevent neurovascular dysfunction. Therefore, the characterization of BC could be used as a pharmaceutical agent for the treatment of cholinergic neurotoxicity-associated neurovascular disorders such as developmental toxicity, vascular dementia, and Alzheimer's disease due to its AChE and AP inhibitory actions.

Artificial intelligence (AI), particularly deep learning as a subcategory of AI, provides opportunities to accelerate and improve the process of discovering and developing new drugs. The use of AI in drug discovery is still in its early stages, but it has the potential to revolutionize the way new drugs are discovered and developed. As AI technology continues to evolve, it is likely that AI will play an even greater role in the future of drug discovery. AI is used to identify new drug targets, design new molecules, and predict the efficacy and safety of potential drugs. The inclusion of AI in drug discovery can screen millions of compounds in a matter of hours, identifying potential drug candidates that would have taken years to find using traditional methods. AI is highly utilized in the pharmaceutical industry by optimizing processes, reducing waste, and ensuring quality control. This review covers much-needed topics, including the different types of machine-learning techniques, their applications in drug discovery, and the challenges and limitations of using machine learning in this field. The state-of-the-art of AI-assisted pharmaceutical discovery is described, covering applications in structure and ligand-based virtual screening, de novo drug creation, prediction of physicochemical and pharmacokinetic properties, drug repurposing, and related topics. Finally, many obstacles and limits of present approaches are outlined, with an eye on potential future avenues for AI-assisted drug discovery and design.

BMC Public Health, 2023 Jul 17;23(1):1364.
PMID: 37461105 DOI: 10.1186/s12889-023-16199-1

INTRODUCTION: Pharmaceutical care services (PCs) have evolved significantly over the last few decades, with a greater focus on patient's safety and proven effectiveness in a wide range of contexts. Many of the evidence supporting this technique comes from the United States, the evaluation and adoption of (PCs) which differ greatly across the globe.
OBJECTIVE: The goal of this study was to identify and assess the efficacy of pharmaceutical care services in various pharmaceutical aspects throughout seventeen Middle Eastern nations.
METHOD: The Arkesy and O'Malley technique was used to conduct a scoping review. It was conducted using PubMed/Medline, Scopus, Cochrane Library, Springer Link, Clinical Trials, and Web of Science etc. The Van Tulder Scale was utilized in randomized trials research, whereas the dawn and black checklists were used in non-randomized trials research. A descriptive and numerical analysis of selected research was done. The scope of eligible PCs, pharmaceutical implementers, study outcomes, and quality were all identified by a thematic review of research.
RESULTS: There were about 431,753 citations found in this study, and 129 publications were found to be eligible for inclusion after analysing more than 271 full-text papers. The study design was varied, with 43 (33.3%) RCTs and 86 (66.7%) n-RCTs. Thirty-three (25.6%) of the studies were published in 2020. Jordan, Saudi Arabia, and Turkey were home to the majority of the studies (25.6%, 16.3%, and 11.6%) respectively. Thirty-seven studies (19.7%) were concerned with resolving drug related problems (DRPs), whereas 27 (14.4%) were concerned with increasing quality of life (QOL) and 23 (12.2%) with improving drug adherence. Additionally, the research revealed that the average ratings of the activities provided to patients improved every year.
CONCLUSION: Studies in the Middle East continue to provide evidence supporting the positive impact of pharmaceutical care services on both hard and soft outcomes measured in most studies. Yet there was rare focus on the value of the implemented services. Thus, rigorous evaluation of the economic impact of implemented pharmaceutical care services in the Middle East and assessment of their sustainability is must.

Enantioselective analysis in complex matrices using capillary electrophoresis-mass spectrometry: A case study of the botanical drug Corydalis Rhizoma

Yan B, Huang ZA, Yahaya N, Chen DDY

J Chromatogr B Analyt Technol Biomed Life Sci, 2020 Sep 01;1152:122216.
PMID: 32531643 DOI: 10.1016/j.jchromb.2020.122216

Enantioselective analysis is critically important in the pharmaceutical and agricultural industries. However, most of the methods reported were developed for the analysis of pure racemates acquired from chemical synthesis or purification. Direct analysis of chiral enantiomers in complex matrices has rarely been reported. This work demonstrated capillary electrophoresis-mass spectrometry (CE-MS) for the enantioselective analysis of botanical drugs for the first time, using a widely used botanical drug, Corydalis Rhizoma, as an example. The method was used for the simultaneous enantioselective analysis of dl-tetrahydropalmatine and (RS)-tetrahydroberberine (canadine) in Corydalis Rhizoma extract. Using (2-hydroxypropyl)-β-cyclodextrin as the chiral selector, a partial filling technique was used to avoid signal suppression and contamination of the MS detector. Post column organic modifier was used to assist with ionization in the flow through microvial CE-MS interface, therefore, organic solvents was not used in the background electrolyte. The completely aqueous background electrolyte contributed to better chiral separations. The CE-MS method established here can directly determine the analytes in their complex matrix without any pre-purification steps, while also offering high sensitivity and low operational costs (including sample, chiral selector and solvent). In the method validation process, good linearity (r > 0.993), sensitivity and accuracy (recoveries within 89.1-110.0%) were demonstrated. The CE-MS technique was shown to be able to provide good selectivity for the simultaneous chiral separation of multiple pairs of enantiomers in complex matrices.

Fulltext Evaluation of Conflicts of Interest among Participants of the Japanese Nephrology Clinical Practice Guideline

Murayama A, Yamada K, Yoshida M, Kaneda Y, Saito H, Sawano T, et al.

Clin J Am Soc Nephrol, 2022 Jun;17(6):819-826.
PMID: 35623883 DOI: 10.2215/CJN.14661121

BACKGROUND AND OBJECTIVES: Rigorous and transparent management strategies for conflicts of interest and clinical practice guidelines with the best available evidence are necessary for the development of nephrology guidelines. However, there was no study assessing financial and nonfinancial conflicts of interest, quality of evidence underlying the Japanese guidelines for CKD, and conflict of interest policies for guideline development.
DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This cross-sectional study examined financial and nonfinancial conflicts of interest among all 142 authors of CKD guidelines issued by the Japanese Society of Nephrology using a personal payment database from all 92 major Japanese pharmaceutical companies between 2016 and 2019 and self-citations by guideline authors. Also, the quality of evidence and strength of recommendations underlying the guidelines and conflicts of interest policies of Japanese, US, and European nephrology societies were evaluated.
RESULTS: Among 142 authors, 125 authors (88%) received $6,742,889 in personal payments from 56 pharmaceutical companies between 2016 and 2019. Four-year combined median payment per author was $8258 (interquartile range, $2230‒$51,617). The amounts of payments and proportion of guideline authors with payments remained stable during and after guideline development. The chairperson, vice chairperson, and group leaders received higher personal payments than other guideline authors. Of 861 references in the guidelines, 69 (8%) references were self-cited by the guideline authors, and 76% of the recommendations were on the basis of low or very low quality of evidence. There were no fully rigorous and transparent conflicts of interest policies for nephrology guideline authors in the United States, Europe, and Japan.
CONCLUSIONS: Most of the Japanese CKD guideline recommendations were on the basis of low quality of evidence by the guideline authors tied with pharmaceutical companies, suggesting the need for better financial conflicts of interest management.

PMID: 37526848 DOI: 10.1007/978-3-031-34567-8_10

The National Pharmaceutical Regulatory Agency (NPRA) is the agency responsible for the registration of pharmaceutical, natural, and health supplement products and notification of cosmetic products that are marketed in Malaysia. The implementation of regulatory oversight of the different types of product was in a progressive manner, with the latest addition to be regulated being the cell and gene therapy products (CGTPs), beginning January 1, 2021. CGTP can be classified as low risk (that does not require registration) or high risk (that needs to be registered). Generally, the regulation of high-risk CGTP is similar to other biological products. This chapter describes the chronology of the CGTP framework, classification of CGTP, how CGTPs fit into the current registration pathways and registration procedure, dossier requirements, and what is the current status and future direction of CGTP in Malaysia.

Promoting the suitability of graphitic carbon nitride and metal oxide nanoparticles: A review of sulfonamides photocatalytic degradation

Zango ZU, Lawal MA, Usman F, Sulieman A, Akhdar H, Eisa MH, et al.

Chemosphere, 2024 Mar;351:141218.
PMID: 38266876 DOI: 10.1016/j.chemosphere.2024.141218

The widespread consumption of pharmaceutical drugs and their incomplete breakdown in organisms has led to their extensive presence in aquatic environments. The indiscriminate use of antibiotics, such as sulfonamides, has contributed to the development of drug-resistant bacteria and the persistent pollution of water bodies, posing a threat to human health and the safety of the environment. Thus, it is paramount to explore remediation technologies aimed at decomposing and complete elimination of the toxic contaminants from pharmaceutical wastewater. The review aims to explore the utilization of metal-oxide nanoparticles (MONPs) and graphitic carbon nitrides (g-C3N4) in photocatalytic degradation of sulfonamides from wastewater. Recent advances in oxidation techniques such as photocatalytic degradation are being exploited in the elimination of the sulfonamides from wastewater. MONP and g-C3N4 are commonly evolved nano substances with intrinsic properties. They possessed nano-scale structure, considerable porosity semi-conducting properties, responsible for decomposing wide range of water pollutants. They are widely applied for photocatalytic degradation of organic and inorganic substances which continue to evolve due to the low-cost, efficiency, less toxicity, and more environmentally friendliness of the materials. The review focuses on the current advances in the application of these materials, their efficiencies, degradation mechanisms, and recyclability in the context of sulfonamides photocatalytic degradation.

The knowledge, attitude, and practice of the public regarding household pharmaceutical waste disposal: a systematic review (2013-2023)

Hiew SY, Low BY

Int J Pharm Pract, 2024 Mar 06;32(2):120-132.
PMID: 38300734 DOI: 10.1093/ijpp/riae001

OBJECTIVE: The improper disposal of household pharmaceutical waste (HPW) is an emerging cause of environmental pollution. Behavioural practices are intricately linked to individuals' knowledge levels and attitudes. Thus, this systematic review aims to assess the knowledge, attitude, and practice (KAP) of HPW disposal among the public and to examine the interconnectedness of these KAP components.
METHODS: A literature review for articles published from 2013 to 2023 was carried out in scientific databases PubMed, Scopus, and Web of Science, identifying quantitative studies involving the assessment of KAP of the public concerning HPW disposal.
RESULTS: This review incorporated 12 studies conducted in Africa, South Asia, and Southeast Asia. Nine studies highlighted a consistent trend of limited to inadequate knowledge regarding safe medication disposal. Notwithstanding, respondents largely exhibited a positive attitude towards proper medication disposal. This encouraging disposition, unfortunately, stands in stark contrast to the reported practices, which appeared to be inadequate. This dissonance might be due to a deficit in accessible disposal facilities and information, compounded with insufficient guidance from healthcare professionals. Interestingly, the majority expressed support for take-back programs aimed at managing unused and expired medications.
CONCLUSION: This review identified a need for a comprehensive understanding of the interconnected dynamics among KAP components regarding safe medication disposal. The exploration of theoretical behavioural frameworks could help predict public intentions to adopt safe medication disposal practices. Ultimately, a multi-faceted approach that addresses knowledge gaps, reinforces positive attitudes, and promotes accessible safe medication disposal services can collectively safeguard the environment and public health.

Fulltext Pharmacological and Safety Profile of Dexlansoprazole: A New Proton Pump Inhibitor - Implications for Treatment of Gastroesophageal Reflux Disease in the Asia Pacific Region

Goh KL, Choi MG, Hsu PI, Chun HJ, Mahachai V, Kachintorn U, et al.

J Neurogastroenterol Motil, 2016 Jul 30;22(3):355-66.
PMID: 26932927 DOI: 10.5056/jnm15150

Although gastroesophageal reflux disease is not as common in Asia as in western countries, the prevalence has increased substantially during the past decade. Gastroesophageal reflux disease is associated with considerable reductions in subjective well-being and work productivity, as well as increased healthcare use. Proton pump inhibitors (PPIs) are currently the most effective treatment for gastroesophageal reflux disease. However, there are limitations associated with these drugs in terms of partial and non-response. Dexlansoprazole is the first PPI with a dual delayed release formulation designed to provide 2 separate releases of medication to extend the duration of effective plasma drug concentration. Dexlansoprazole has been shown to be effective for healing of erosive esophagitis, and to improve subjective well-being by controlling 24-hour symptoms. Dexlansoprazole has also been shown to achieve good plasma concentration regardless of administration with food, providing flexible dosing. Studies in healthy volunteers showed no clinically important effects on exposure to the active metabolite of clopidogrel or clopidogrel-induced platelet inhibition, with no dose adjustment of clopidogrel necessary when coprescribed. This review discusses the role of the new generation PPI, dexlansoprazole, in the treatment of gastroesophageal reflux disease in Asia.

Malays J Med Sci, 2018 May;25(3):1-6.
PMID: 30899182 DOI: 10.21315/mjms2018.25.3.1

The use of serious games as digital medicine started in recent years as the United States Food and Drug Administration granted Class 1 or 2 device clearance to serious games or game-like technologies. This encouraging trend motivates interdisciplinary cooperation between experts in the medical sciences and the game industry because the Northern American pharmaceutical revenues have exceeded USD1 trillion globally since 2014. The potential of this lucrative business opportunity may attract fund providers and venture capitalists to support game-related research and development projects. The author elaborates his activities and experiences in the United States in FY2017/2018 as a Humphrey fellow from Malaysia. Specifically, the research and development trend of serious games for cognitive function in the academic and the game industry has positive impact on how medical doctors and practitioners in low- and middle-income countries may use or develop games as digital medicine.

Suah FB, Ahmad M, Heng LY

Spectrochim Acta A Mol Biomol Spectrosc, 2015 Jun 5;144:81-7.
PMID: 25748985 DOI: 10.1016/j.saa.2015.02.068

A novel approach for the determination of Al(3+) from aqueous samples was developed using an optode membrane produced by physical inclusion of Al(3+) selective reagent, which is morin into a plasticized poly(vinyl chloride). The inclusion of Triton X-100 was found to be valuable and useful for enhancing the sorption of Al(3+) ions from liquid phase into the membrane phase, thus increasing the intensity of optode's absorption. The optode showed a linear increase in the absorbance at λ(max)=425 nm over the concentration range of 1.85×10(-6)-1.1×10(-4) mol L(-1) (0.05-3 μg mL(-1)) of Al(3+) ions in aqueous solution after 5 min. The limit of detection was determined to be 1.04×10(-6) mol L(-1) (0.028 μg mL(-1)). The optode developed in the present work was easily prepared and found to be stable, has good mechanical strength, sensitive and reusable. In addition, the optode was tested for Al(3+) determination in lake water, river water and pharmaceutical samples, which the result was satisfactory.

Marine carbohydrates are most important organic molecules made by photosynthetic organisms. It is very essential for humankind: the role in being an energy source for the organism and they are considered as an important dissolve organic compound (DOC) in marine environment's sediments. Carbohydrates found in different marine environments in different concentrations. Polysaccharides of carbohydrates play an important role in various fields such as pharmaceutical, food production, cosmeceutical, and so on. Marine organisms are good resources of nutrients, and they are rich carbohydrate in sulfated polysaccharide. Seaweeds (marine microalgae) are used in different pharmaceutical industries, especially in pharmaceutical compound production. Seaweeds have a significant amount of sulfated polysaccharides, which are used in cosmeceutical industry, besides based on the biological applications. Since then, traditional people, cosmetics products, and pharmaceutical applications consider many types of seaweed as an important organism used in food process. Sulfated polysaccharides containing seaweed have potential uses in the blood coagulation system, antiviral activity, antioxidant activity, anticancer activity, immunomodulating activity, antilipidepic activity, etc. Some species of marine organisms are rich in polysaccharides such as sulfated galactans. Various polysaccharides such as agar and alginates, which are extracted from marine organisms, have several applications in food production and cosmeceutical industries. Due to their high health benefits, compound-derived extracts of marine polysaccharides have various applications and traditional people were using them since long time ago. In the future, much attention is supposed to be paid to unraveling the structural, compositional, and sequential properties of marine carbohydrate as well.

Usir E, Lua PL, Majeed AB

J Pharm Pract, 2012 Jun;25(3):374-80.
PMID: 22551563 DOI: 10.1177/0897190012442218

This study aimed to determine the availability and usage of printed and electronic references and Patient Medication Record in community pharmacy. It was conducted for over 3 months from 15 January to 30 April 2007. Ninety-three pharmacies participated. Structured questionnaires were mailed to community pharmacies. Six weeks later a reminder was sent to all non responders, who were given another six weeks to return the completed questionnaire. Outcomes were analyzed using descriptive statistics and chi-square test of independence. Almost all the pharmacies (96.8%) have at least Monthly Index of Medical Specialties (MIMS) while 78.5% have at least MIMS ANNUAL in their stores. Only about a third (31.2%) of the pharmacies were equipped with online facilities of which the majority referred to medical websites (88.9%) with only a minority (11.1%) referring to electronic journals. More than half (59.1%) of the pharmacists kept Patient Medication Record profiles with 49.1% storing it in paper, 41.8% electronically and 9.1% in both printed and electronic versions. In general, prevalence and usage of electronic references in community pharmacies were rather low. Efforts should be increased to encourage wider usage of electronic references and Patient Medication Records in community pharmacies to facilitate pharmaceutical care.

Fulltext Ligand-based virtual screening using Bayesian inference network and reweighted fragments

Ahmed A, Abdo A, Salim N

ScientificWorldJournal, 2012;2012:410914.
PMID: 22623895 DOI: 10.1100/2012/410914

Many of the similarity-based virtual screening approaches assume that molecular fragments that are not related to the biological activity carry the same weight as the important ones. This was the reason that led to the use of Bayesian networks as an alternative to existing tools for similarity-based virtual screening. In our recent work, the retrieval performance of the Bayesian inference network (BIN) was observed to improve significantly when molecular fragments were reweighted using the relevance feedback information. In this paper, a set of active reference structures were used to reweight the fragments in the reference structure. In this approach, higher weights were assigned to those fragments that occur more frequently in the set of active reference structures while others were penalized. Simulated virtual screening experiments with MDL Drug Data Report datasets showed that the proposed approach significantly improved the retrieval effectiveness of ligand-based virtual screening, especially when the active molecules being sought had a high degree of structural heterogeneity.

Application of chemometrics in understanding the spatial distribution of human pharmaceuticals in surface water

Al-Odaini NA, Zakaria MP, Zali MA, Juahir H, Yaziz MI, Surif S

Environ Monit Assess, 2012 Nov;184(11):6735-48.
PMID: 22193630 DOI: 10.1007/s10661-011-2454-3

The growing interest in the environmental occurrence of veterinary and human pharmaceuticals is essentially due to their possible health implications to humans and ecosystem. This study assesses the occurrence of human pharmaceuticals in a Malaysian tropical aquatic environment taking a chemometric approach using cluster analysis, discriminant analysis and principal component analysis. Water samples were collected from seven sampling stations along the heavily populated Langat River basin on the west coast of peninsular Malaysia and its main tributaries. Water samples were extracted using solid-phase extraction and analyzed using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) for 18 pharmaceuticals and one metabolite, which cover a range of six therapeutic classes widely consumed in Malaysia. Cluster analysis was applied to group both pharmaceutical pollutants and sampling stations. Cluster analysis successfully clustered sampling stations and pollutants into three major clusters. Discriminant analysis was applied to identify those pollutants which had a significant impact in the definition of clusters. Finally, principal component analysis using a three-component model determined the constitution and data variance explained by each of the three main principal components.

Use of prebiotics in oral delivery of bioactive compounds: a nanotechnology perspective

Heidarpour F, Mohammadabadi MR, Zaidul IS, Maherani B, Saari N, Hamid AA, et al.

Pharmazie, 2011 May;66(5):319-24.
PMID: 21699064

The oral route is considered the most patient-convenient means of drug administration. In recent years there has been a tendency to employ smart carrier systems that enable controlled or timed release of a bioactive material, thereby providing a better dosing pattern and minimizing side effects. Nano-encapsulation systems (nanocarriers) offer important advantages over conventional drug delivery techniques. Nanocarriers can protect the drug from chemical/enzymatic degradation and enhance bioavailability. Prebiotics are ideal ingredients for the nano-encapsulation and oral drug delivery due to their natural ability to protect the encapsulated compound in the upper gasterointestinal (GI) tract. Here the potential of prebiotics for oral delivery of drugs and other bioactives is reviewed.
