Abstract
In this research, we have modified tocopheryl polyethylene glycol succinate (TPGS) to a redox-sensitive material, denoted as TPGS-SH, and employed the same to develop dual-receptor-targeted nanoparticles of chitosan loaded with cabazitaxel (CZT). The physicochemical properties and morphological characteristics of all nanoparticle formulations were assessed. Dual-receptor targeting redox-sensitive nanoparticles of CZT (F-CTX-CZT-CS-SH-NPs) were developed by a combination of pre- and postconjugation techniques by incorporating synthesized chitosan-folate (F) and TPGS-SH during nanoparticle synthesis and further postconjugated with cetuximab (CTX) for epidermal growth factor receptor (EGFR) targeting. The in vitro release of the drug was seemingly higher in the redox-sensitive buffer media (GSH, 20 mM) compared to that in physiological buffer. However, the extent of cellular uptake of dual-targeted nanoparticles was significantly higher in A549 cells than other control nanoparticles. The IC50 values of F-CTX-CZT-CS-SH-NPs against A549 cells was 0.26 ± 0.12 μg/mL, indicating a 6.3-fold and 60-fold enhancement in cytotoxicity relative to that of dual-receptor targeted, nonredox sensitive nanoparticles and CZT clinical injection, respectively. Furthermore, F-CTX-CZT-CS-SH-NPs demonstrated improved anticancer activity in the benzo(a)pyrene lung cancer model with a higher survival rate. Due to the synergistic combination of enhanced permeability and retention (EPR) effect of small-sized nanoparticles, the innovative and redox sensitive TPGS-SH moiety and the dual folate and EGFR mediated augmented endocytosis have all together significantly enhanced their biodistribution and targeting exclusively to the lung which is evident from their ultrasound/photoacoustic and in vivo imaging system (IVIS) studies.

Abstract
The treatment of several ocular inflammatory conditions affecting different areas of the ocular globe involves the administration of topical ophthalmic formulations containing corticosteroids. This research was aimed at evaluating the solubilising efficacy of 5.0% w/w of different binary mixtures of commercial amphiphilic polymeric surfactants with the purpose of obtaining nanomicellar solutions containing a high amount of loteprednol etabonate (LE). The selected LE-TPGS/HS nanomicelles, containing 0.253 mg/mL of the drug, had a small size (=13.57 nm) and uniform distribution (Polydispersity Index = 0.271), appeared completely transparent and perfectly filterable through 0.2 μm membrane filter, and remained stable up to 30 days at 4 °C. The critical micellar concentration (CMCTPGS/HS) was 0.0983 mM and the negative value of the interaction parameter between the polymeric-surfactant-building unit (βTPGS/HS = -0.1322) confirmed the ability of the polymeric surfactants to interact, favouring the dissolution of LE into nanomicelles. The disappearance of the endothermic peak of LE in the DSC analysis confirmed the interactions of LE with the polymeric surfactants. LE-TPGS/HS produced in vitro LE which sustained diffusion for 44 h (more than 40% of encapsulated LE). Furthermore, the lack of a significant cytotoxic effect on a sensitive corneal epithelial cell line makes it a candidate for further biological studies.

Abstract
Malaria is one of the world's most devastating diseases, infecting well over 300 million people annually and killing between 2 and 3 million worldwide. Increasing parasite resistance to many existing drugs is exacerbating disease. Resistance to commonly used malarial drugs is increasing the need to develop new drugs urgently. Due to the slow pace and substantial costs of new drug development, repurposing of old drugs which is recently increasingly becoming an attractive proposition of highly efficient and effective way of drug discovery led us to study the drug rifampicin for this purpose. The present paper aims to investigate the route of Plasmodium falciparum apicoplast-targeted proteins that putatively encode β subunits of RNA polymerase with an objective to develop an effective antimalarial drug. Homology searching for conserved binding site to the rifampicin drug and the functional analysis of rpoB gene were done. Multiple Sequence alignment analysis of rpoB was compared with that in E.coli - rpoB and M. tuberculosis - rpoB. Docking studies of Rifampicin - rpoB complex was also done for finding binding affinity. The results of computational studies showed that rifampicin is a potential drug for malaria.

TPGS Decorated Liposomes as Multifunctional Nano-Delivery Systems. Pharm Res 2023; 40:245-263. [PMID: 36376604 PMCID: PMC9663195 DOI: 10.1007/s11095-022-03424-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Accepted: 10/23/2022] [Indexed: 11/16/2022]
Abstract
Liposomes are sphere-shaped vesicles that can capture therapeutics either in the outer phospholipid bilayer or inner aqueous core. Liposomes, especially when surface-modified with functional materials, have been used to achieve many benefits in drug delivery, including improving drug solubility, oral bioavailability, pharmacokinetics, and delivery to disease target sites such as cancers. Among the functional materials used to modify the surface of liposomes, the FDA-approved non-ionic surfactant D-alpha-tocopheryl polyethylene glycol succinate (TPGS) is increasingly being applied due to its biocompatibility, lack of toxicity, applicability to various administration routes and ability to enhance solubilization, stability, penetration and overall pharmacokinetics. TPGS decorated liposomes are emerging as a promising drug delivery system for various diseases and are expected to enter the market in the coming years. In this review article, we focus on the multifunctional properties of TPGS-coated liposomes and their beneficial therapeutic applications, including for oral drug delivery, vaccine delivery, ocular administration, and the treatment of various cancers. We also suggest future directions to optimise the manufacture and performance of TPGS liposomes and, thus, the delivery and effect of encapsulated diagnostics and therapeutics.

Abstract
AbstractThe rapid advancement of nanomedicine presents novel alternatives that have the
potential to transform health care. Targeted drug delivery as well as the
synthesis of nanocarriers is a growing discipline that has been intensively
researched to reduce the complexity of present medicines in a variety of
diseases and to develop new treatment and diagnostic techniques. There are
several designed nanomaterials used as a delivery system such as liposomes,
micelles, dendrimers, polymers, carbon-based materials, and many other
substances, which deliver the drug moiety directly into its targeted body area
reducing toxic effect of conventional drug delivery, thus reducing the amount of
drug required for therapeutic efficacy and offering many more advantages.
Currently, these are used in many applications, including cancer treatment,
imaging contrast agents, and biomarker detection and so on. This review provides
a comprehensive update in the field of targeted nano-based drug delivery
systems, by conducting a thorough examination of the drug synthesis, types,
targets, and application of nanomedicines in improving the therapeutic
efficiency.
