    Sonali, Singh RP, Sharma G, Kumari L, Koch B, Singh S, et al.
    Colloids Surf B Biointerfaces, 2016 Nov 01;147:129-141.
    PMID: 27497076 DOI: 10.1016/j.colsurfb.2016.07.058
    The aim of this work was to formulate RGD-TPGS decorated theranostic liposomes, which contain both docetaxel (DTX) and quantum dots (QDs) for brain cancer imaging and therapy. RGD conjugated TPGS (RGD-TPGS) was synthesized and conjugation was confirmed by Fourier transform infrared (FTIR) spectroscopy and electrospray ionisation (ESI) mass spectroscopy (ESI-MS). The theranostic liposomes were prepared by the solvent injection method and characterized for their particle size, polydispersity, zeta-potential, surface morphology, drug encapsulation efficiency, and in-vitro release study. Biocompatibility and safety of theranostic liposomes were studied by reactive oxygen species (ROS) generation study and histopathology of brain. In-vivo study was performed for determination of brain theranostic effects in comparison with marketed formulation (Docel™) and free QDs. The particle sizes of the non-targeted and targeted theranostic liposomes were found in between 100 and 200nm. About 70% of drug encapsulation efficiency was achieved with liposomes. The drug release from RGD-TPGS decorated liposomes was sustained for more than 72h with 80% of drug release. The in-vivo results demonstrated that RGD-TPGS decorated theranostic liposomes were 6.47- and 6.98-fold more effective than Docel™ after 2h and 4h treatments, respectively. Further, RGD-TPGS decorated theranostic liposomes has reduced ROS generation effectively, and did not show any signs of brain damage or edema in brain histopathology. The results of this study have indicated that RGD-TPGS decorated theranostic liposomes are promising carrier for brain theranostics.

    Hussain Z, Thu HE, Ng SF, Khan S, Katas H
    Colloids Surf B Biointerfaces, 2017 Feb 01;150:223-241.

    Wound healing is a multifarious and vibrant process of replacing devitalized and damaged cellular structures, leading to restoration of the skin's barrier function, re-establishment of tissue integrity, and maintenance of the internal homeostasis. Curcumin (CUR) and its analogs have gained widespread recognition due to their remarkable anti-inflammatory, anti-infective, anticancer, immunomodulatory, antioxidant, and wound healing activities. However, their pharmaceutical significance is limited due to inherent hydrophobic nature, poor water solubility, low bioavailability, chemical instability, rapid metabolism and short half-life. Owing to their pharmaceutical limitations, newer strategies have been attempted in recent years aiming to mitigate problems related to the effective delivery of curcumanoids and to improve their wound healing potential. These advanced strategies include nanovesicles, polymeric micelles, conventional liposomes and hyalurosomes, nanocomposite hydrogels, electrospun nanofibers, nanohybrid scaffolds, nanoconjugates, nanostructured lipid carriers (NLCs), nanoemulsion, nanodispersion, and polymeric nanoparticles (NPs). The superior wound healing activities achieved after nanoencapsulation of the CUR are attributed to its target-specific delivery, longer retention at the target site, avoiding premature degradation of the encapsulated cargo and the therapeutic superiority of the advanced delivery systems over the conventional delivery. We have critically reviewed the literature and summarize the convincing evidence which explore the pharmaceutical significance and therapeutic feasibility of the advanced delivery systems in improving wound healing activities of the CUR and its analogs.

    Ali A, Akhtar J, Ahmad U, Basheer AS, Jaiswal N, Jahan A
    Crit Rev Ther Drug Carrier Syst, 2022;40(1):1-48.
    PMID: 36374840 DOI: 10.1615/CritRevTherDrugCarrierSyst.2022039241
    Colorectal cancer (CRC) is the second most common cause of cancer related deaths in the United States. However, more than half of all incidence and mortality are caused by risk factors such as smoking, unhealthy diet, excessive alcohol consumption, inactivity, and excess weight, and thus can be protected. CRC morbidity and mortality can also be reduced by proper screening and monitoring. Over the last few years the amalgamation of nanotechnology with healthcare system has brought about the potential to administer the delivery of certain therapeutic drugs to cancer cells without affecting normal tissues. Recent strategies combine the diagnostic and therapeutic approaches to improve the overall performance of cancer nanomedicines. Targeted cancer nanotherapeutics provides many more opportunities for the selective detection of toxic chemicals within cancer cells. The distinctive features of nanoparticles, such as their small size, large surface to volume ratio, and the ability of nanoparticles to achieve several interactions of ligands at surface, offer great benefits of nanomedicines to treat various types of cancers. This review highlights the molecular mechanisms of colorectal carcinogenesis and discusses various key concepts in the development of nanotherapeutics targeted for CRC treatment.

    Anniebell S, Gopinath SCB
    Curr Med Chem, 2018;25(12):1433-1445.
    PMID: 28093984 DOI: 10.2174/0929867324666170116123633
    BACKGROUND: Research interest on the properties of polymer conjugated gold nanoparticle (GNP) in biomedicine is rapidly rising because of the extensive evidences for their unique properties. In the field of biomedicine, GNPs have been widely used because of their inertness and low levels of cytotoxicity. Therefore, when exposed to cells, they are less prone to exert damaging effects. GNPs are capable of being functionalized as desired and are ideal as they do not encourage undesired side reactions that might counter react with the intention of the functionalization. Biofouling is an occurrence that takes place at cellular and biological molecular level, binds non-specifically on the detection surface and forms a wrong output. This undesired incidence can be avoided by conjugating the surface of biomolecules with polymers. Densely packed repeating chains of polymers such as polyethylene glycol are capable of decreasing non-specific reactions. Applications of polymer conjugated GNPs in the field of biomedicine are as biosensors, delivery and therapeutic agents.

    CONCLUSION: Therefore, the properties and applications of polymer conjugated GNPs are studied widely as overviewed here.

    Woon CK, Hui WK, Abas R, Haron MH, Das S, Lin TS
    Curr Neuropharmacol, 2022;20(8):1498-1518.
    PMID: 34923947 DOI: 10.2174/1570159X20666211217163540
    Alzheimer's disease (AD) affects the elderly and is characterized by progressive neurodegeneration caused by different pathologies. The most significant challenges in treating AD include the inability of medications to reach the brain because of its poor solubility, low bioavailability, and the presence of the blood-brain barrier (BBB). Additionally, current evidence suggests the disruption of BBB plays an important role in the pathogenesis of AD. One of the critical challenges in treating AD is the ineffective treatments and their severe adverse effects. Nanotechnology offers an alternative approach to facilitate the treatment of AD by overcoming the challenges in drug transport across the BBB. Various nanoparticles (NP) loaded with natural products were reported to aid in drug delivery for the treatment of AD. The nano-sized entities of NP are great platforms for incorporating active materials from natural products into formulations that can be delivered effectively to the intended action site without compromising the material's bioactivity. The review highlights the applications of medicinal plants, their derived components, and various nanomedicinebased approaches for the treatment of AD. The combination of medicinal plants and nanotechnology may lead to new theragnostic solutions for the treatment of AD in the future.

    Jeevanandam J, Danquah MK, Debnath S, Meka VS, Chan YS
    Curr Pharm Biotechnol, 2015;16(10):853-70.
    PMID: 26212563 DOI: 10.2174/1389201016666150727120618
    Diabetes mellitus has been a threat to humans for many years. Amongst the different diabetes types, type 2 diabetes mellitus is the most common, and this is due to drastic changes in human lifestyle such as lack of exercise, stressful life and so on. There are a large number of conventional treatment methods available for type 2 diabetes mellitus. However, most of these methods are curative and are only applicable when the patient is highly symptomatic. Effective treatment strategies should be geared towards interfering with cellular and bio molecular mechanisms associated with the development and sustenance of the disease. In recent years, research into the medical potential of nanoparticles has been a major endeavor within the pharmaceutical industries. Nanoparticles display unique and tuneable biophysical characteristics which are determined by their shape and size. Nanoparticles have been used to manifest the properties of drugs, and as carriers for drug and vaccine delivery. Notwithstanding, there are further opportunities for nanoparticles to augment the treatment of a wide range of life threatening diseases that are yet to be explored. This review article seeks to highlight the application of potential nano-formulations in the treatment of type 2 diabetes mellitus. In addition, the activity of nanomedicine supplements in reversing insulin resistance is also discussed.

    Sharma PA, Maheshwari R, Tekade M, Tekade RK
    Curr Pharm Des, 2015;21(30):4465-78.
    PMID: 26354926
    The increasing prevalence and complexity of cardiovascular diseases demand innovative strategies for diagnostic and therapeutic applications to improve patient care/prognoses. Additionally, various factors constrain present cardiovascular therapies, including low aqueous drug solubility, early metabolism, short half-life and drug delivery limitations. The efficient treatment of cardiovascular diseases requires improvement of traditional drug delivery systems. This can be accomplished by using novel nanomaterial that can incorporate diverse bio-actives along with diagnostic agents in a single carrier, referred to as theranostics. This review discusses the state of the art in the applications to diagnosis and therapy of innovative, nanomaterial- based strategies such as lipid based carriers, nanocapsules, magnetic nanoparticles, gold nanoparticles, protein conjugated nanoparticles, dendrimers and carbon-based nanoformulations with a special emphasis on how they can contribute to improving the management of cardiovascular disease.

    Carbon nanotubes (CNTs) possess outstanding properties that could be useful in several technological, drug delivery, and diagnostic applications. However, their unique physical and chemical properties are hindered due to their poor solubility. This article review's the different ways and means of solubility enhancement of single-wall carbon nanotubes (SWNTs). The advantages of SWNTs over the multi-walled carbon nanotubes (MWNTs) and the method of non-covalent modification for solubility enhancement has been the key interest in this review. The review also highlights a few examples of dispersant design. The review includes some interesting utility of SWNTs being wrapped with polymer especially in biological media that could mediate proper drug delivery to target cells. Further, the use of wrapped SWNTs with phospholipids, nucleic acid, and amphiphillic polymers as biosensors is of research interest. The review aims at summarizing the developments relating to wrapped SWNTs to generate further research prospects in healthcare.

  11. PEGylation: a promising strategy to overcome challenges to cancer-targeted nanomedicines: a review of challenges to clinical transition and promising resolution
    Hussain Z, Khan S, Imran M, Sohail M, Shah SWA, de Matas M
    Drug Deliv Transl Res, 2019 06;9(3):721-734.
    PMID: 30895453 DOI: 10.1007/s13346-019-00631-4
    On account of heterogeneity, intrinsic ability of drug resistance, and the potential to invade to other parts of the body (malignancy), the development of a rational anticancer regimen is dynamically challenging. Chemotherapy is considered the gold standard for eradication of malignancy and mitigation of its reoccurrence; nevertheless, it has also been associated with detrimental effects to normal tissues owing to its nonselectivity and nominal penetration into the tumor tissues. In recent decades, nanotechnology-guided interventions have been well-acclaimed due to their ability to facilitate target-specific delivery of drugs, avoidance of nontarget distribution, alleviated systemic toxicity, and maximized drug internalization into cancer cells. Despite their numerous biomedical advantages, clinical translation of nanotechnology-mediated regimens is challenging due to their short plasma half-life and early clearance. PEGylation of nanomedicines has been adapted as an efficient strategy to extend plasma half-life and diminished early plasma clearance via alleviating the opsonization (uptake by monocytes and macrophages) of drug nanocarriers. PEGylation provides "stealth" properties to nanocarrier's surfaces which diminished their recognition or uptake by cellular immune system, leading to longer circulation time, reduced dosage and frequency, and superior site-selective delivery of drugs. Therefore, this review aims to present a comprehensive overview of the pharmaceutical advantages and therapeutic feasibility of PEGylation of nanocarriers in improving tumor-specific targetability, reversing drug resistance, and improving pharmacokinetic profile of drugs and anticancer efficacy. Challenges to PEGylated cancer nanomedicines, possible adaptations to resolve those challenges, and pivotal requirement for interdisciplinary research for development of rational anticancer regimen have also been pondered.

  12. Fulltext Experimental and molecular modeling approach to optimize suitable polymers for fabrication of stable fluticasone nanoparticles with enhanced dissolution and antimicrobial activity
    Ahmed S, Govender T, Khan I, Rehman NU, Ali W, Shah SMH, et al.
    Drug Des Devel Ther, 2018;12:255-269.
    PMID: 29440875 DOI: 10.2147/DDDT.S148912
    Background and aim: The challenges with current antimicrobial drug therapy and resistance remain a significant global health threat. Nanodrug delivery systems are playing a crucial role in overcoming these challenges and open new avenues for effective antimicrobial therapy. While fluticasone (FLU), a poorly water-soluble corticosteroid, has been reported to have potential antimicrobial activity, approaches to optimize its dissolution profile and antimicrobial activity are lacking in the literature. This study aimed to combine an experimental study with molecular modeling to design stable FLU nanopolymeric particles with enhanced dissolution rates and antimicrobial activity.

    Methods: Six different polymers were used to prepare FLU nanopolymeric particles: hydroxyl propyl methylcellulose (HPMC), poly (vinylpyrrolidone) (PVP), poly (vinyl alcohol) (PVA), ethyl cellulose (EC), Eudragit (EUD), and Pluronics®. A low-energy method, nanoprecipitation, was used to prepare the polymeric nanoparticles.

    Results and conclusion: The combination of HPMC-PVP and EUD-PVP was found most effective to produce stable FLU nanoparticles, with particle sizes of 250 nm ±2.0 and 280 nm ±4.2 and polydispersity indices of 0.15 nm ±0.01 and 0.25 nm ±0.03, respectively. The molecular modeling studies endorsed the same results, showing highest polymer drug binding free energies for HPMC-PVP-FLU (-35.22 kcal/mol ±0.79) and EUD-PVP-FLU (-25.17 kcal/mol ±1.12). In addition, it was observed that Ethocel® favored a wrapping mechanism around the drug molecules rather than a linear conformation that was witnessed for other individual polymers. The stability studies conducted for 90 days demonstrated that HPMC-PVP-FLU nanoparticles stored at 2°C-8°C and 25°C were more stable. Crystallinity of the processed FLU nanoparticles was confirmed using differential scanning calorimetry, powder X-ray diffraction analysis and TEM. The Fourier transform infrared spectroscopy (FTIR) studies showed that there was no chemical interaction between the drug and chosen polymer system. The HPMC-PVP-FLU nanoparticles also showed enhanced dissolution rate (P<0.05) compared to the unprocessed counterpart. The in vitro antibacterial studies showed that HPMC-PVP-FLU nanoparticles displayed superior effect against gram-positive bacteria compared to the unprocessed FLU and positive control.

  13. Fulltext Berberine nanoparticles with enhanced in vitro bioavailability: characterization and antimicrobial activity
    Sahibzada MUK, Sadiq A, Faidah HS, Khurram M, Amin MU, Haseeb A, et al.
    Drug Des Devel Ther, 2018;12:303-312.
    PMID: 29491706 DOI: 10.2147/DDDT.S156123
    BACKGROUND: Berberine is an isoquinoline alkaloid widely used in Ayurveda and traditional Chinese medicine to treat illnesses such as hypertension and inflammatory conditions, and as an anticancer and hepato-protective agent. Berberine has low oral bioavailability due to poor aqueous solubility and insufficient dissolution rate, which can reduce the efficacy of drugs taken orally. In this study, evaporative precipitation of nanosuspension (EPN) and anti-solvent precipitation with a syringe pump (APSP) were used to address the problems of solubility, dissolution rate and bioavailability of berberine.

    METHODS: Semi-crystalline nanoparticles (NPs) of 90-110 nm diameter for APSP and 65-75 nm diameter for EPN were prepared and then characterized using differential scanning calorimetry (DSC) and X-ray powder diffractometry (XRD). Thereafter, drug content solubility and dissolution studies were undertaken. Berberine and its NPs were evaluated for their antibacterial activity.

    RESULTS: The results indicate that the NPs have significantly increased solubility and dissolution rate due to conversion of the crystalline structure to a semi-crystalline form.

    CONCLUSION: Berberine NPs produced by both APSP and EPN methods have shown promising activities against Gram-positive and Gram-negative bacteria, and yeasts, with NPs prepared through the EPN method showing superior results compared to those made with the APSP method and the unprocessed drug.

    Theranostics has the potential to revolutionize the diagnosis, treatment, and prognosis of cancer, where novel drug delivery systems could be used to detect the disease at an early stage with instantaneous treatment. Various preclinical approaches of nanoemulsions with entrapped contrast and chemotherapeutic agents have been documented to act specifically on the tumor microenvironment (TME) for both diagnostic and therapeutic purposes. However, bringing these theranostic nanoemulsions through preclinical trials to patients requires several fundamental hurdles to be overcome, including the in vivo behavior of the delivery tool, degradation, and clearance from the system, as well as long-term toxicities. Here, we discuss recent advances in the application of nanoemulsions in molecular imaging with simultaneous therapeutic efficacy in a single delivery system.

    A tumor serves as a major avenue in drug development owing to its complexity. Conventional therapies against tumors possess limitations such as suboptimal therapeutic efficacy and extreme side effects. These display poor pharmacokinetics and lack specific targeting, with non-specific distribution resulting in systemic toxicity. Therefore, nanocarriers targeted against cancers are increasingly being explored. Nanomedicine aids in maintaining a balance between efficacy and toxicity by specifically accumulating in tumors. Nanotherapeutics possess advantages such as increased solubility of chemotherapeutics, encapsulation of multiple drugs and improved biodistribution, and can ensure tumor-directed drug delivery and release via the approaches of passive targeting and active targeting. This review aims to offer a general overview of the current advances in tumor-targeting nanocarriers for clinical and diagnostic use.

    Highly controllable dendritic structural design means dendrimers are a leading carrier in drug delivery applications. Dendrimer- and other nanocarrier-based hybrid systems are an emerging platform in the field of drug delivery. This review is a compilation of increasing reports of dendrimer interactions, such as dendrimer-liposome, dendrimer-carbon-nanotube, among others, known as hybrid carriers. This should prompt entirely new research with promising results for these hybrid carriers. It is assumed that such emerging hybrid nanosystems - from combining two already-established drug delivery platforms - could lead the way for the development of newer delivery systems with multiple applicability for latent theranostic applications in the future.

    Skin diseases are the fourth leading non-fatal skin conditions that act as a burden and affect the world economy globally. This condition affects the quality of a patient's life and has a pronounced impact on both their physical and mental state. Treatment of these skin conditions with conventional approaches shows a lack of efficacy, long treatment duration, recurrence of conditions, systemic side effects, etc., due to improper drug delivery. However, these pitfalls can be overcome with the applications of nanomedicine-based approaches that provide efficient site-specific drug delivery at the target site. These nanomedicine-based strategies are evolved as potential treatment opportunities in the form of nanocarriers such as polymeric and lipidic nanocarriers, nanoemulsions along with emerging others viz. carbon nanotubes for dermatological treatment. The current review focuses on challenges faced by the existing conventional treatments along with the topical therapeutic perspective of nanocarriers in treating various skin diseases. A total of 213 articles have been reviewed and the application of different nanocarriers in treating various skin diseases has been explained in detail through case studies of previously published research works. The toxicity related aspects of nanocarriers are also discussed.
