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
