Abstract
Self-assembled peptides and specifically small peptide based nanostructures have been the focus of research in past decade due to their potential biological applications. In this study, we prepared a protected peptide, Boc-Pro-Phe-Gly-OMe, which self-assembled in aqueous solutions leading to the formation of nanostructures and ability to act as a drug carrier. Dynamic light scattering (DLS) measurements showed nanostructures with average size of 119.6 nm containing hydrophobic core, wherein hydrophobic drugs, viz, eosin, aspirin and curcumin, were successfully encapsulated. These encapsulated nanostructures, were further stabilized with Vitamin E–TPGS. In-vitro drug release studies revealed the release of drugs in controlled fashion from the nanostructures. The results advocate the potential of the proposed peptide nanostructures as controlled drug delivery systems and could be used in other biomedical applications.

Artificial intelligence for Natural Products Discovery and Development
Our approach involves using computational methods to predict the potential therapeutic benefits of natural products by considering factors such as drug structure, targets, and interactions. We also employ multitarget analysis to understand the role of drug targets in disease pathways. We advocate for the use of artificial intelligence in predicting ...read more
Chemistry Based on Natural Products for Therapeutic Purposes
The development of new pharmaceuticals for a wide range of medical conditions has long relied on the identification of promising natural products (NPs). There are over sixty percent of cancer, infectious illness, and CNS disease medications that include an NP pharmacophore, according to the Food and Drug Administration. Since NP ...read more
Current Trends in Drug Discovery Based on Artificial Intelligence and Computer-Aided Drug Design
Drug development discovery has faced several challenges over the years. In fact, the evolution of classical approaches to modern methods using computational methods, or Computer-Aided Drug Design (CADD), has shown promising and essential results in any drug discovery campaign. Among these methods, molecular docking is one of the most notable ...read more
