چکیده مقاله:

This study aims to design some dual-target anticancer candidates, capable to act as an alkylating agent as well as a thymidylate synthase (TS) inhibitor. The designed scaffold is a combination of nucleobase, amino acid and aziridine structures. The candidates are docked into TS and three DNA double strand structures and evaluated based on their binding interaction energies and ligand efficiencies, compared to several reference drugs. The ADME properties of the alkylating agents are also predicted. The designed ligands exhibit improved interaction energies and lower ligand efficiencies with respect to the reference drugs. Among the ligands, L4 is the best DNA binding agent and L2, L5 and L6 are the best TS inhibitors. In addition, the thioTEPA based Ser and Met analogues are the strongest and poorest alkylating agents, respectively. Further, molecular dynamics simulations on the best ligand-target complexes, i.e. L4-4AWL and L6-TS systems, provide evidences for the potential L6 and L4 anti-proliferation activities.

TRPV1: A Target for Rational Drug Design

Transient Receptor Potential Vanilloid 1 (TRPV1) is a non-selective, Ca(2+) permeable cation channel activated by noxious heat, and chemical ligands, such as capsaicin and resiniferatoxin (RTX). Many compounds have been developed that either activate or inhibit TRPV1, but none of them are in routine clinical practice. This review will discuss the rationale for antagonists and agonists of TRPV1 ...

Anticancer Drug Discovery — From Serendipity to Rational Design

Cancer is nowadays used as a generic term describing a group of about 120 different diseases, which can affect any part of the body and defined as the state characterized by the uncontrolled growth and invasion of normal tissues and spread of cells [1]. According to WHO reports cancer is a leading cause of premature death worldwide, accounting for 7.6 million deaths (around 13% of all deaths) o...

Dual inhibitors of β-amyloid aggregation and acetylcholinesterase as multi-target anti-Alzheimer drug candidates.

Notwithstanding the functional role that the aggregates of some amyloidogenic proteins can play in different organisms, protein aggregation plays a pivotal role in the pathogenesis of a large number of human diseases. One of such diseases is Alzheimer's disease (AD), where the overproduction and aggregation of the β-amyloid peptide (Aβ) are regarded as early critical factors. Another protein th...

Rational drug design.

In this article, current knowledge of drug design is reviewed and an approach of rational drug design is presented. The process of drug development is challenging, expensive, and time consuming, although this process has been accelerated due to the development of computational tools and methodologies. The current target based drug design approach is incomplete because most of the drugs develope...

Mycotoxin- A Target for Anticancer Drug Development

The aim of this present article is to underscore the recent evidence linking anticancer activity and free radical scavenging activity of mycotoxins and its significance in the development of newer anticancer drugs. Although acute exposure to a massive amount of mycotoxin is rare but long-term exposure/consumption of food with low levels of lipophilic mycotoxin remains problematic. The aneuploid...
