and topoisomerase IV inhibitors that demonstrate potent activity against a range of Gram-positive and selected Gram-negative organisms, including clinically-relevant and drug-resistant strains. In part1, we present a detailed structure activity relationship (SAR) analysis that led to the discovery of our previously disclosed compound, REDX05931, which has a minimum inhibitory concentration (MIC) of
针对细菌感染的药物有效性令人震惊的下降,迫切需要开发新的抗菌剂来绕过细菌耐药机制。我们在此报告了一系列 DNA 促旋酶和拓扑异构酶 IV 抑制剂,它们对一系列革兰氏阳性和选定的革兰氏阴性生物体(包括临床相关和耐药菌株)表现出有效的活性。在第 1 部分中,我们提出了详细的构效关系 (SAR) 分析,导致我们发现了我们之前公开的化合物 REDX05931,该化合物对耐氟喹诺酮类金黄色葡萄球菌的最小抑制浓度 (MIC) 为 0.06 μg mL -1。虽然在体外 hERG 和 CYP 抑制阻止了进一步的发展,它验证了一种合理的设计方法来解决这一紧迫的未满足的医疗需求,并为进一步优化提供了一个支架,在第 2 部分中介绍。

or pharmaceutically acceptable salts thereof that are modulators of the C5a receptor. Also provided are pharmaceutical compositions and methods of use including the treatment of diseases or disorders involving pathologic activation from C5a and non-pharmaceutical applications.
to the discovery of other challenging kinase inhibitors without protein–ligand structural information. Furthermore, our optimization effort identified the highly potent and orally available 5,7-isoquinoline 37 from the second chemicalseries. Compound 37 showed good efficacy in a mouse collagen-induced arthritis model. The in vivo studies suggest that PKCζ inhibition is a novel target for rheumatoid
This invention relates to antibacterial and anti-mycobacterial drug compounds of formula I. It also relates to pharmaceutical formulations of antibacterial drug compounds. It also relates to uses of the derivatives in treating bacterial infections and to methods of treating bacterial infections. The invention is also directed to antibacterial drug compounds which are capable of treating bacterial infections which are currently hard to treat with existing drug compounds, e.g. those caused by resistant bacterial or mycobacterial strains.

This invention relates to a series of compounds of formula (I) for use in treating infections caused by obligate anaerobic bacteria, including Clostridium difficile, and to methods of treating said infections by administering said compounds. The compounds can be used against strains of obligate anaerobic bacteria that have developed resistance to other antibiotics. Many compounds used in the invention contain a tricyclic ring system.
