Design, Synthesis, and Biological Evaluation of New 1-(Aryl-1H-pyrrolyl)(phenyl)methyl-1H-imidazole Derivatives as Antiprotozoal Agents
摘要:
We have designed and synthesized a series of new imidazole-based compounds structurally related to an antiprotozoal agent with nanomolar activity which we identified recently. The new analogues possess micromolar activities against Trypanosoma brucei rhodesiense and Leishmania donovani and nanomolar potency against Plasmodium falciparum. Most of the analogues displayed IC50 within the low nanomolar range against Trypanosoma cruzi, with very high selectivity toward the parasite. Discussion of structure activity relationships and in vitro biological data for the new compounds are provided against a number of different protozoa. The mechanism of action for the most potent derivatives (Si, 6a-c, and 8b) was assessed by a target-based assay using recombinant T. cruzi GYPS1. Bioavailability and efficacy of selected hits were assessed in a T. cruzi mouse model, where 6a and 6b reduced parasitemia in animals >99% following intraperitoneal administration of 25 mg/kg/day dose for 4 consecutive days.

molecules. The isocyanide–isocyanide [3+2] cross‐cycloadditionreaction constitutes a straightforward method to access imidazoles starting from the easily available chemicals. So far, only three successive reports are known and all lead to the formation of 1,4‐disubstituted imidazoles. Here, we report the first isocyanide–isocyanide [3+2] cross‐cycloadditionreaction allowing for the formation of 1,4,5‐trisubstituted
