    PMID: 36364071 DOI: 10.3390/molecules27217241
    Alzheimer's disease (AD) has been associated with the hallmark features of cholinergic dysfunction, amyloid beta (Aβ) aggregation and impaired synaptic transmission, which makes the associated proteins, such as β-site amyloid precursor protein cleaving enzyme 1 (BACE I), acetylcholine esterase (AChE) and synapsin I, II and III, major targets for therapeutic intervention. The present study investigated the therapeutic potential of three major phytochemicals of Rosmarinus officinalis, ursolic acid (UA), rosmarinic acid (RA) and carnosic acid (CA), based on their binding affinity with AD-associated proteins. Detailed docking studies were conducted using AutoDock vina followed by molecular dynamic (MD) simulations using Amber 20. The docking analysis of the selected molecules showed the binding energies of their interaction with the target proteins, while MD simulations comprising root mean square deviation (RMSD), root mean square fluctuation (RMSF) and molecular mechanics/generalized born surface area (MM/GBSA) binding free energy calculations were carried out to check the stability of bound complexes. The drug likeness and the pharmacokinetic properties of the selected molecules were also checked through the Lipinski filter and ADMETSAR analysis. All these bioactive compounds demonstrated strong binding affinity with AChE, BACE1 and synapsin I, II and III. The results showed UA and RA to be potential inhibitors of AChE and BACE1, exhibiting binding energies comparable to those of donepezil, used as a positive control. The drug likeness and pharmacokinetic properties of these compounds also demonstrated drug-like characteristics, indicating the need for further in vitro and in vivo investigations to ascertain their therapeutic potential for AD.

In the crystal, the mol-ecules are linked into chains parallel to [001] by N-H⋯O hydrogen bonds. The chains are further connected into a three-dimensional network by π-π stacking inter-actions with centroid-centroid distances of 3.6538 (10) and 3.8995 (11) Å.
  4. Natural and synthetic polymer-based smart biomaterials for management of ulcerative colitis: a review of recent developments and future prospects
    Sohail M, Mudassir, Minhas MU, Khan S, Hussain Z, de Matas M, et al.
    Drug Deliv Transl Res, 2019 04;9(2):595-614.

    Ulcerative colitis (UC) is an inflammatory disease of the colon that severely affects the quality of life of patients and usually responds well to anti-inflammatory agents for symptomatic relief; however, many patients need colectomy, a surgical procedure to remove whole or part of the colon. Though various types of pharmacological agents have been employed for the management of UC, the lack of effectiveness is usually predisposed to various reasons including lack of target-specific delivery of drugs and insufficient drug accumulation at the target site. To overcome these glitches, many researchers have designed and characterized various types of versatile polymeric biomaterials to achieve target-specific delivery of drugs via oral route to optimize their targeting efficiency to the colon, to improve drug accumulation at the target site, as well as to ameliorate off-target effects of chemotherapy. Therefore, the aim of this review was to summarize and critically discuss the pharmaceutical significance and therapeutic feasibility of a wide range of natural and synthetic biomaterials for efficient drug targeting to colon and rationalized treatment of UC. Among various types of biomaterials, natural and synthetic polymer-based hydrogels have shown promising targeting potential due to their innate pH responsiveness, sustained and controlled release characteristics, and microbial degradation in the colon to release the encapsulated drug moieties. These characteristic features make natural and synthetic polymer-based hydrogels superior to conventional pharmacological strategies for the management of UC.
  5. Neuroprotective effect from stem bark extracts of Knema laurina against H₂O₂- and Aβ(1-42)-induced cell death in human SH-SY5Y cells
    Ismail N, Akhtar MN, Ismail M, Zareen S, Shah SA, Lajis NH, et al.
    Nat Prod Res, 2015;29(16):1571-4.
    PMID: 25471591 DOI: 10.1080/14786419.2014.985676
    The stem bark extracts of Knema laurina inhibited the hydrogen peroxide (H2O2)- and aggregated amyloid β-peptide 1-42 length (Aβ(1-42))-induced cell death in differentiated SH-SY5Y cells. Exposure of 250 μM H2O2 or 20 μM Aβ(1-42) to the cells for 24 h reduced 50% of cell viability. Pretreatment of cells with ethyl acetate extract (EAE) or n-butanol extract (BE) at 300 μg/mL and then exposure to H2O2 protected the cells against the neurotoxic effects of H2O2. Besides, methanolic extract (ME) at 1 and 10 μg/mL exerted neuroprotective effect on Aβ(1-42)-induced toxicity to the cells. These results showed that EAE, BE and ME exhibited neuroprotective activities against H2O2- and Aβ(1-42)-induced cell death. Flavonoids (3-6) and β-sitosterol glucoside (8) were isolated from the EAE. Compound 1 was isolated from hexane extract, and compounds 2 and 7 were isolated from dichloromethane extract. All these observations provide the possible evidence for contribution in the neuroprotective effects.

    PMID: 29742941 DOI: 10.1080/01480545.2018.1459669
    The present study investigates the neuroprotective effects of Foeniculum vulgare seeds in a lead (Pb)-induced brain neurotoxicity mice model. The dried seeds extract of Foeniculum vulgare was prepared with different concentrations of organic solvents (ethanol, methanol, n-hexane). The in vitro antioxidant activity of Foeniculum vulgare seed extracts was assessed through DPPH assay and the chemical composition of the extracts was determined by high-resolution 1H NMR spectroscopy. The age-matched male Balb/c mice (divided into 9 groups) were administered with 0.1% Pb and 75% and 100% ethanol extracts of Foeniculum vulgare seeds at a dose of 200 mg/kg/day and 20 mg/kg/day. The maximum antioxidant activity was found for 75% ethanol extract, followed by 100% ethanol extract. Gene expression levels of oxidative stress markers (SOD1 and Prdx6) and the three isoforms of APP (APP common, 770 and 695), in the cortex and hippocampus of the treated and the control groups were measured. Significant increase in APP 770 expression level while a substantial decrease was observed for SOD1, Prdx6 and APP 695 expression in Pb-treated groups. Interestingly, the deranged expression levels were significantly normalized by the treatment with ethanol extracts of Foeniculum vulgare seeds (specifically at dose of 200 mg/kg/day). Furthermore, the Pb-induced morphological deterioration of cortical neurons was significantly improved by the ethanol extracts of Foeniculum vulgare seeds. In conclusion, the present findings highlight the promising therapeutic potential of Foeniculum vulgare to minimize neuronal toxicity by normalizing the expression levels of APP isoforms and oxidative stress markers.
  7. New class of acetylcholinesterase inhibitors from the stem bark of Knema laurina and their structural insights
    Akhtar MN, Lam KW, Abas F, Maulidiani, Ahmad S, Shah SA, et al.
    Bioorg Med Chem Lett, 2011 Jul 1;21(13):4097-103.
    PMID: 21641207 DOI: 10.1016/j.bmcl.2011.04.065
    Bioassay-guided extraction of the stem bark of Knema laurina showed the acetylcholinesterase (AChE) inhibitory activity of DCM and hexane fractions. Further repeated column chromatography of hexane and DCM fractions resulted in the isolation and purification of five alkenyl phenol and salicylic acid derivatives. New compounds, (+)-2-hydroxy-6-(10'-hydroxypentadec-8'(E)-enyl)benzoic acid (1) and 3-pentadec-10'(Z)-enylphenol (2), along with known 3-heptadec-10'(Z)-enylphenol (3), 2-hydroxy-6-(pentadec-10'(Z)-enyl)benzoic acid (4), and 2-hydroxy-6-(10'(Z)-heptadecenyl)benzoic acid (5) were isolated from the stem bark of this plant. Compounds (1-5) were tested for their acetylcholinesterase inhibitory activity. The structures of these compounds were elucidated by the 1D and 2D NMR spectroscopy, mass spectrometry and chemical derivatizations. Compound 5 showed strong acetylcholinesterase inhibitory activity with IC(50) of 0.573 ± 0.0260 μM. Docking studies of compound 5 indicated that the phenolic compound with an elongated side chain could possibly penetrate deep into the active site of the enzyme and arrange itself through π-π interaction, H-bonding, and hydrophobic contacts with some critical residues along the complex geometry of the active gorge.

    INTRODUCTION: Gestational diabetes mellitus (GDM) exerts a great impact on the placenta and reflects changes on placentas both morphological and functionally. The aims of this study are to evaluate the prevalence of placental histopathological lesions in pregnancies complicated by GDM compared to gestational age-matched controls, and their association with maternal and fetal complications.

    METHODS: Fifty-four singleton GDM-complicated pregnancies were recruited and compared to 33 consecutive normal pregnancies. Two pathologists, blinded to all clinical data, reviewed and evaluated all histological samples of the placentas in accordance with Amsterdam criteria. Relevant demographic, clinical data and primary birth outcomes were recorded.

    RESULTS: A myriad of histomorphological abnormalities, including chronic inflammation (n = 9/54, p = 0.031), histological chorioamnionitis (n = 23/54, p 

  10. Fulltext Non-tenera Contamination and the Economic Impact of SHELL Genetic Testing in the Malaysian Independent Oil Palm Industry

    Oil palm (Elaeis guineensis) is the most productive oil bearing crop worldwide. It has three fruit forms, namely dura (thick-shelled), pisifera (shell-less) and tenera (thin-shelled), which are controlled by the SHELL gene. The fruit forms exhibit monogenic co-dominant inheritance, where tenera is a hybrid obtained by crossing maternal dura and paternal pisifera palms. Commercial palm oil production is based on planting thin-shelled tenera palms, which typically yield 30% more oil than dura palms, while pisifera palms are female-sterile and have little to no palm oil yield. It is clear that tenera hybrids produce more oil than either parent due to single gene heterosis. The unintentional planting of dura or pisifera palms reduces overall yield and impacts land utilization that would otherwise be devoted to more productive tenera palms. Here, we identify three additional novel mutant alleles of the SHELL gene, which encode a type II MADS-box transcription factor, and determine oil yield via control of shell fruit form phenotype in a manner similar to two previously identified mutant SHELL alleles. Assays encompassing all five mutations account for all dura and pisifera palms analyzed. By assaying for these variants in 10,224 mature palms or seedlings, we report the first large scale accurate genotype-based determination of the fruit forms in independent oil palm planting sites and in the nurseries that supply them throughout Malaysia. The measured non-tenera contamination rate (10.9% overall on a weighted average basis) underscores the importance of SHELL genetic testing of seedlings prior to planting in production fields. By eliminating non-tenera contamination, comprehensive SHELL genetic testing can improve sustainability by increasing yield on existing planted lands. In addition, economic modeling demonstrates that SHELL gene testing will confer substantial annual economic gains to the oil palm industry, to Malaysian gross national income and to Malaysian government tax receipts.

    PMID: 24800102 DOI: 10.1155/2014/472157
    Background. The nonmotor symptoms are important determinants of health and quality of life in Parkinson's disease but are not well recognized and addressed in clinical practice. This study was conducted to determine the prevalence of nonmotor symptoms and their impact on quality of life in patients with Parkinson's disease. Methods. This was a cross-sectional study among patients with idiopathic Parkinson's disease. Exclusion criteria were a Mini Mental State Examination score of <21/30. Prevalence of nonmotor symptoms was determined using the NMSQuest. The severity of nonmotor symptoms and the quality of life were assessed using validated disease-specific questionnaires (PDQ-39 and NMSS). Results. A total of 113 patients consisting of 60 males and 53 females were recruited. The median duration of illness was 5.0 (2.0-8.0) years. The prevalence rate of nonmotor symptoms in our cohort was 97.3%. The most common reported nonmotor symptom in our cohort was gastrointestinal (76.1%). We found that the severity of the nonmotor symptoms was associated with poorer quality of life scores (r s : 0.727, P < 0.001). Conclusions. Nonmotor symptoms were highly prevalent in our patients with Parkinson's disease and adversely affected the quality of life of our patients. In contrast to western studies, the most common nonmotor symptom is gastrointestinal. The possibility of an Asian diet playing a role in this observation requires further study.
  12. Fulltext Novel Bi-heterocycles as Potent Inhibitors of Urease and Less Cytotoxic Agents: 3-({5-((2-Amino-1,3-thiazol-4-yl)methyl)-1,3,4-oxadiazol-2-yl}sulfanyl)-N-(un/substituted-phenyl)propanamides

    Iran J Pharm Res, 2020;19(1):487-506.
    PMID: 32922502 DOI: 10.22037/ijpr.2019.13084.11362
    The synthesis of a novel series of bi-heterocyclic propanamides, 7a-l, was accomplished by S-substitution of 5-[(2-amino-1,3-thiazol-4-yl)methyl]-1,3,4-oxadiazol-2-thiol (3). The synthesis was initiated from ethyl 2-(2-amino-1,3-thiazol-4-yl)acetate (1) which was converted to corresponding hydrazide, 2, by hydrazine hydrate in methanol. The refluxing of hydrazide, 2, with carbon disulfide in basic medium, resulted in 5-[(2-amino-1,3-thiazol-4-yl)methyl]-1,3,4-oxadiazol-2-thiol (3). A series of electrophiles, 6a-l, was synthesized by stirring un/substituted anilines (4a-l) with 3-bromopropanoyl chloride (5) in a basic aqueous medium. Finally, the targeted compounds, 7a-l, were acquired by stirring 3 with newly synthesized electrophiles, 6a-l, in DMF using LiH as a base and an activator. The structures of these bi-heterocyclic propanamides were confirmed through spectroscopic techniques, such as IR, 1H-NMR, 13C-NMR, and EI-MS. These molecules were tested for their urease inhibitory potential, whereby, the whole series exhibited very promising activity against this enzyme. Their cytotoxic behavior was ascertained through hemolysis and it was observed that all these were less cytotoxic agents. The in-silico molecular docking analysis of these molecules was also in full agreement with their in-vitro enzyme inhibition data.
  13. Novel functional antimicrobial and biocompatible arabinoxylan/guar gum hydrogel for skin wound dressing applications
    Khan MUA, Raza MA, Razak SIA, Abdul Kadir MR, Haider A, Shah SA, et al.
    J Tissue Eng Regen Med, 2020 10;14(10):1488-1501.
    PMID: 32761978 DOI: 10.1002/term.3115
    It is a challenging task to develop active biomacromolecular wound dressing materials that are biocompatible and possesses antibacterial properties against the bacterial strains that cause severe skin disease. This work is focused on the preparation of a biocompatible and degradable hydrogel for wound dressing application using arabinoxylan (ARX) and guar gum (GG) natural polymers. Fourier transform infrared spectroscopy (FT-IR) confirmed that both ARX and GG interacted well with each other, and their interactions further increased with the addition of crosslinker tetraethyl orthosilicate. Scanning electron microscope (SEM) micrographs showed uniform porous morphologies of the hydrogels. The porous morphologies and uniform interconnected pores are attributed to the increased crosslinking of the hydrogel. Elastic modulus, tensile strength, and fracture strain of the hydrogels significantly improved (from ATG-1 to ATG-4) with crosslinking. Degradability tests showed that hydrogels lost maximum weight in 7 days. All the samples showed variation in swelling with pH. Maximum swelling was observed at pH 7. The hydrogel samples showed good antibacterial activity against Pseudomonas aeruginosa (Gram-negative) and Staphylococcus aureus (Gram-positive) in PBS, good drug release profile (92% drug release), and nontoxic cellular behavior. The cells not only retained their cylindrical morphologies onto the hydrogel but were also performing their normal activities. It is, therefore, believed that as-developed hydrogel could be a potential material for wound dressing application.

    PMID: 23903802 DOI: 10.1007/s10157-013-0844-2
    Secondary hyperparathyroidism (SHPT) is common in end-stage renal disease. Our primary objective was to evaluate the efficacy of oral paricalcitol versus oral calcitriol on serum intact parathyroid hormone (iPTH) and mineral bone parameters in continuous ambulatory peritoneal dialysis (CAPD) patients with SHPT. The secondary objective was to analyze highly sensitive C-reactive protein (hsCRP) and peritoneal membrane function in both groups.
  15. Overview on Epigenetic Re-programming: A Potential Therapeutic Intervention in Triple Negative Breast Cancers
    Mohamad Hanif EA, Shah SA
    Asian Pac J Cancer Prev, 2018 Dec 25;19(12):3341-3351.
    PMID: 30583339
    Breast cancer treatments leads to variable responses. Hormonal therapy is beneficial to receptor positive breast cancer
    subtypes and display better clinical outcome than triple negative breast cancers (TNBCs) with FEC (5-Fluorouracil,
    Epirubicin and Cyclophosphamide) the mainstay chemotherapy regiment. Owning to their negative expressions of
    estrogen (ER), progesterone (PR) and HER2 receptors, disease recurrence and metastasis befalls some patients indicating
    resistance to FEC. Involvement of epigenetic silencing through DNA methylation, histone methylation, acetylation and
    sumoylation may be the key player in FEC chemoresistance. Epigenetic and molecular profiling successfully classified
    breast cancer subtypes, indicating potential driver mechanisms to the progression of TNBCs but functional mechanisms
    behind chemoresistance of these molecular markers are not well defined. Several epigenetic inhibitors and drugs have
    been used in the management of cancers but these attempts are mainly beneficial in hematopoietic cancers and not
    specifically favourable in solid tumours. Hypothetically, upon administration of epigenetic drugs, recovery of tumour
    suppressor genes is expected. However, high tendency of switching on global metastatic genes is predicted. Polycomb
    repressive complex (PRC) such as EZH2, SETD1A, DNMT, is known to have repressive effects in gene regulation and
    shown to inhibit cell proliferation and invasion in breast cancers. Individual epigenetic regulators may be an option
    to improve chemo-drug delivery in cancers. This review discussed on molecular signatures of various breast cancer
    subtypes and on-going attempts in understanding underlying molecular mechanisms of epigenetic regulators as well
    as providing insights on possible ways to utilize epigenetic enzymes/inhibitors with responses to chemotherapeutic
    drugs to re-program cellular and biological outcome in TNBCs.

    Muhammad NA, Omar K, Shah SA, Muthupalaniappen L, Arshad F
    Asia Pac J Clin Nutr, 2008;17(4):597-602.
    PMID: 19114396
    BACKGROUND: Worldwide the prevalence of overweight and obesity in children is escalating. Parents’ recognition of overweight or obesity in their own children is very important for a successful intervention in these children. This study examined parental perception of their children’s weight status, and its association with their knowledge on nutrition and obesity.
    MATERIALS AND METHODS: This was a cross sectional study of parents with children aged 9 to 12 years, in a primary school of Kuala Lumpur. Parents responded to a self-administered questionnaire which contains parental perception of their child weight status as well as knowledge on nutrition and obesity. The parents’ perception of the children’s weight status was then compared with the actual measured weight status.
    RESULTS: There were 204 parents who participated in the study. Parents were found to underestimate their child weight status and 38.2% were inaccurate in their perception. The mean score of knowledge on nutrition and obesity was 78.5±14.4; and this did not associate with the accuracy of their perception on the child weight status. Parents showed inadequate knowledge in food pyramid and preparation of low fat meals.
    CONCLUSION: The Malaysian Health Campaigns had resulted in overall good knowledge on nutrition and obesity in the parents except in few domains. However, this was insufficient to make the parents recognize the growing overweight and obesity problem in their children.

    Cancer is responsible for substantial burden on communities and more specifically on less developed countries. The incidence of cancer is on the rise due to population growth and aging, also due to increment of the risk factors such as smoking, increasing weight, low physical activity associated with adoption of western lifestyle. Around 14 million cases of new cancer and 8 million deaths from cancer is estimated to occur by 2012. This cross-sectional study was conducted in Baghdad from June 2016 to October 2016. Participants were selected according to our inclusion criteria, namely aged between 18 to 40 years and not being diagnosed with any chronic diseases. Those who fulfilled the inclusion criteria were 700 participants who completed the questionnaire. Results showed that most of our participants had low perceived susceptibility to cancer risk (62.4%), low perceived severity (59.8%), but good perceived benefits of screening (56.6%). Hierarchal linear regression analysis showed that sociodemographic factors of gender, marital status, and education level were statistically significant. Moreover, factors of health behaviour such as practice towards health and preventive behaviour were associated with the outcome. Finally, treatment control and emotional factors were mostly predicting the outcome. Perceived susceptibility to cancer along with its psychological factors and behaviour were important contributors to self-perceived health in this study. Hence there is association between perception and future morbidity and mortality, thus it is crucial for public health policy. Comprehensive health programs that include health promotion campaigns and proper health care services that deals with secondary prevention.
  18. Perceptions of Malaysian colorectal cancer patients regarding dietary intake: a qualitative exploration
    Yusof AS, Isa ZM, Shah SA
    Asian Pac J Cancer Prev, 2013;14(2):1151-4.
    PMID: 23621204
    BACKGROUND: Changes in dietary practices are known to be associated with changes in the health and disease pattern of a population. This study aimed to qualitatively explore the perception of colorectal cancer patients regarding causes of colorectal cancer and the influence of diet.

    MATERIALS AND METHODS: Twelve respondents from three major ethnicities in Malaysia were selected from the quantitative study on dietary pattern and colorectal cancer carried out earlier in this study. In-depth interviews (IDI), conducted from April until June 2012, were mainly in the Malay language with additional use of English and continued until the saturation point was reached. All interviews were autorecorded so that verbatim transcriptions could be created.

    RESULTS: Causes of colorectal cancer were categorized into internal and external factors. The majority of respondents agreed that there is an association between Western foods and colorectal cancer. Malaysian traditional diet was not related to colorectal cancer as less preservative agents were used. Malaysian diet preparation consisting of taste of cooking (spicy, salty and sour foods) plus type of cooking (fry, grilled and smoked) were considered causes of colorectal cancer. All respondents changed their dietary pattern to healthy food after being diagnosed with colorectal cancer. Advice from doctors regarding suitable food for colorectal cancer was useful in this regard.

    CONCLUSIONS: Eating outside, use of food flavoring ingredients and preservative agents were considered to be the main factors causing colorectal cancer. All respondents admitted that they changed to a healthy diet after being diagnosed with colorectal cancer.
