Discovery of the disubstituted oxazole analogues as a novel class anti-tuberculotic agents against MDR- and XDR-MTB
摘要:
A high-throughput screening effort on 45,000 compounds resulted in the discovery of a disubstituted oxazole as a new structural class inhibitor of Mycobacterium tuberculosis (Mtb). In order to improve the activity and investigate the SAR of this scaffold, a series of disubstituted azole analogues have been designed and synthesized. The newly synthesized compounds 1a-y were evaluated for their in vitro anti-TB activity versus replicating, multi-and extensive drug resistant Mtb strains. All the compounds, except 1o, 1p and 1q, showed potent anti-TB activity with MIC of 1-64 mg/L. The test of broad spectrum panel revealed that this series are specific to Mtb. The cytotoxicity assessment indicated that the compounds were not cytotoxic against HEK 293 cells. The compounds could have a novel mechanism to anti-Mtb as they can inhibit drug sensitive and drug resistant Mtb. (C) 2015 Elsevier Ltd. All rights reserved.

The present invention related to compounds of formula (I) wherein R1, R2, ring A and ring Bare as defined in the claims. The compounds are potent inhibitors of the sodium-calcium exchanger (NCX) and are useful in the treatment or prevention of various clinical conditions in which intracellular calcium homeostasis is disturbed, including ischemic diseases and arrhythmias. In particular, the compounds of formula (I) are useful as inotropic agents in the treatment and 10 prevention of conditions in which inotropic support is required to maintain a sufficient level of blood supply, for example, in the treatment of heart failure or in the treatment of patients undergoing surgery.
