  Piperazinyl quinolines as chemosensitizers to increase fluconazole susceptibility of Candida albicans clinical isolates

  摘要：

  The effectiveness of the potent antifungal drug fluconazole is being compromised by the rise of drug-resistant fungal pathogens. While inhibition of Hsp90 or calcineurin can reverse drug resistance in Candida, such inhibitors also impair the homologous human host protein and fungal-selective chemosensitizers remain rare. The MLPCN library was screened to identify compounds that selectively reverse fluconazole resistance in a Candida albicans clinical isolate, while having no antifungal activity when administered as a single agent. A piperazinyl quinoline was identified as a new small-molecule probe (ML189) satisfying these criteria. (C) 2011 Elsevier Ltd. All rights reserved.

  The present invention is directed to activators of cylindrical proteases ("ACPs"), particularly ClpP, and the role thereof in the diagnosis and treatment of bacterial infections. A number of ACPs were identified that activate caseinolytic protease P ("ClpP"), which independently can only degrade small peptides. In the presence of ACPs, ClpP may be activated to allow it to degrade larger proteins, hence, abolishing the specificity arising from the ATP-dependent chaperones. Members of the ACPs were found to have bactericidal activity. As such, ACPs represent a new classes of compounds that can activate ClpP and that can be developed as potential novel antibiotics.

  本发明涉及圆柱形蛋白酶（“ACPs”）的激活剂，特别是ClpP，以及其在细菌感染的诊断和治疗中的作用。已经确定了许多激活酪蛋白酶P（“ClpP”）的ACP，独立地只能降解小肽。在存在ACP的情况下，ClpP可以被激活，使其能够降解更大的蛋白质，从而消除了ATP依赖的分子伴侣引起的特异性。发现了ACP成员具有杀菌活性。因此，ACP代表了一类新的化合物，可以激活ClpP，并可以作为潜在的新型抗生素开发。
