Recent Trends in the Development of Benzimidazole Hybrid Derivatives and Their Antimalarial Activities

Abstract

A parasite of the Plasmodium species initiates malaria. The parasite is transmitted to communities through the bite of an infected mosquito. Malarial resistance towards the commonly used antimalarial agents is a genuine human health problem. Benzimidazole derivatives exhibit a wide range of antimalarial activities against Plasmodium falciparum (P. falciparum) strain. The present review has summarized the antimalarial activity of benzimidazole hybrid derivatives and described its structural activity relationship (SAR) and quantitative structural-activity relationship (QSAR) model. A total of 14 papers were systematically reviewed. The literature survey has revealed that novel benzimidazole hybrid derivatives diminished the P. falciparum activity in the liver and gametocyte stages and inhibited heme synthesis and β-hematin formation. The QSAR models explain imminent antimalarial agent s growth through multiple linear regression (MLR) and artificial neural networks (ANN).
