Article Abstract

Solid Lipid Nanoparticles (SLNs) are versatile nano-carriers for wide range of applications. The advantages of SLNs include ease of preparation, low toxicity, high active compound bioavailability, flexibility of incorporating hydrophilic and lipophilic drugs, and feasibility of large-scale production. This review provides an overview on the preparation methods of the SLNs, the micro and nanostructure characteristics of the SLNs, and the different factors influencing sustained release and targeted drug delivery. The applications in agriculture and environment, cosmetics, wound healing, malarial treatment, gene therapy and nano-vaccines, and cancer therapy, are elaborated. The mechanisms such as passive, active, and co-delivery are discussed. The issues, challenges and the way forward with ionisable SLNs for delivery of gene and vaccines, RAS-targeted therapy, and bioactive compounds, are highlighted. In combination with multiple compounds and the potential for integration with nature/bio-based solutions, SLNs are proven to be effective, and practical for diverse applications.

Alzheimer's Disease (AD) is the leading cause of dementia worldwide, with significant cognitive and behavioural impairments that devastate individuals and their families. Cohort-level findings, demonstrate the broader population-level implications of Sleep and Circadian Rhythm Disruption (SCRD) in AD and underscore the need for early interventions, emphasizing the importance of timely action. However, the mechanism remains unclear.

Purpose: mutations are classically seen in non-small cell lung cancers (NSCLCs), and EGFR-directed inhibitors have changed the therapeutic landscape in patients with -mutated NSCLC. The real-world prevalence of -mutated ovarian cancers has not been previously described. We aim to determine the prevalence of pathogenic or likely pathogenic mutations in ovarian cancer and describe a case of -mutated metastatic ovarian cancer with a durable response to osimertinib, an EGFR-directed targeted therapy.

Resistance-conferring mutations in the androgen receptor (AR) ligand-binding pocket (LBP) compromise the effectiveness of clinically approved orthosteric AR antagonists. Targeting the dimerization interface pocket (DIP) of AR presents a promising therapeutic approach. In this study, we report the design and optimization of -(thiazol-2-yl) furanamide derivatives as novel AR DIP antagonists, among which was the most promising candidate.

In light of the success of blockbuster drugs for type 2 diabetes and obesity based on the GLP-1 hormone, drugmakers have concentrated their efforts on developing new and improved variations that address the route of administration, dosing, pathway selectivity, or polypharmacology. While some of these modifications have demonstrated improved efficacy in clinical studies and offered exciting opportunities for treating other diseases, drug-induced shifts to the conformational landscape of target receptors may have consequences for side effects. Our review summarizes advances in the understanding of the biochemistry, pharmacogenomics, and molecular pharmacology of incretins and their cognate receptors.
