Targeting Falcipain-2 (FP2) for the development of antimalarials is a promising and established concept in antimalarial drug discovery and development. FP2, a member of papain-family cysteine protease of the malaria parasite Plasmodium falciparum holds an important role in hemoglobin degradation pathway. A new series of quinoline carboxamide-based compounds was designed, synthesized and evaluated for antimalarial activity. We integrated molecular hybridization strategy with in-silico drug design to develop FP2 inhibitors. In-vitro results of FP2 inhibition by Qs17, Qs18, Qs20 and Qs21 were found to be in low micromolar range with IC50 4.78, 7.37, 2.14 and 2.64 μM, respectively. Among the 25 synthesized compounds, four compounds showed significant antimalarial activities. These compounds also depicted morphological and food-vacuole abnormalities much better than that of E-64, an established FP2 inhibitor. Overall these aromatic substituted quinoline carboxamides can serve as promising leads for the development of novel antimalarial agents.

A series of fused and functionalized pyridine derivatives were designed, synthesized and tested for their potential antitubercular properties. All these novel compounds were prepared by using multistep methods involving the construction of pyridine ring as a key synthetic step. Some of these compounds were found to be interesting when tested for their antitubercular properties in vitro and one of them appeared as an attractive and potential antitubercular agent.
