Guanabenz-related amidinohydrazones: potent non-azole inhibitors of aldosterone biosynthesis
摘要:
A new series of potent, guanabenz-derived, non-steroidal aldosterone biosynthesis inhibitors are presented. Salient features of the structure-activity relationship indicate the requirement of a hydrophobic core, presence of a hydrophilic (or basic) peripheral appendage, and, in some cases, profound dependence on hydrazone stereochemistry. The most potent compound of the series, 29, was 2 orders of magnitude more potent than guanabenz as an aldosterone biosynthesis inhibitor.

except with concomitant introduction of an imine C‐alkyl group. The activity of these analogues againstMRSA and VRE ranged from 8 μg mL−1 to inactive (MIC>128 μg mL−1) with the naphthyl and indole analogues. Gram‐negative activity was most promising with two compounds at 16 μg mL−1 against E. coli. Against P. aeruginosa, the highest activity observed was with MIC values of 32 μg mL−1 with another two analogues
罗非替丁的去对称化(1:N ',2-二((E)-4-氯苄叉)肼-1-羧酰亚胺肼)和亚胺烷基取代基的引入具有良好的抗生素活性。值得注意的是,两种类似物对耐万古霉素的肠球菌(VRE)的效力有所提高,其中一种的MIC为0.5μgmL -1。发现有五个类似物比铅1具有更强的效价。吲哚部分的引入导致针对甲氧西林抗性金黄色葡萄球菌(MRSA)的活性最强的robenidine类似物,MIC为1.0μgmL -1。亚胺C = NH等位基因(C = O / C = S)不活跃。单体类似物为16–64μgmL-1对MRSA和VRE有效。缺少末端酰肼NH部分的类似物在64μgmL -1下显示适度的革兰氏阴性活性。研究表明,在16–64μgmL -1下, 4-叔丁基类似物对革兰氏阳性和阴性菌株均具有活性。通常,除伴随引入亚胺C-烷基外,对芳香族基团的其他修饰耐受性差。这些类似物对MRSA和VRE的活性范围为8μgmL
