Synthesis and antifilarial activity of chalcone–thiazole derivatives against a human lymphatic filarial parasite, Brugia malayi
摘要:
Here we report the synthesis of novel chalcone thiazole compounds and their antifilarial activity. The antifilarial properties of these hybrids were assessed against microfilariae as well as adult worms of Brugia malayi. Among all the synthesized compounds, only two compounds, namely 4g and 4n were identified to be promising in vitro. These active compounds were tested in B. malayi-jird (Meriones unguiculatus) and B. malayi-Mastomys coucha models. Compound 4n showed 100% embryostatic effect and 49% macrofilaricidal in jirds and M. coucha models, respectively. This study provides a new structural clue for the development of novel antifilarial lead molecules. (C) 2014 Elsevier Masson SAS. All rights reserved.

A series of novel hybrids possessing chalcone and thiazole moieties were synthesized and evaluated for their antibacterial activities. In general this class of hybrids exhibited potency against Staphylococcus aureus, and in particular, compound 27 exhibited potent inhibitory activity with respect to other synthesized hybrids. Furthermore, the hemolytic and toxicity data demonstrated that the compound 27 was nonhemolytic and nontoxic to mammalian cells. The in vivo studies utilizing a S. aureus septicemia model demonstrated that compound 27 was as potent as vancomycin. The results of antibacterial activities underscore the potential of this scaffold that can be utilized for developing a new class of novel antibiotics.
