The global increase in multidrug-resistant pathogens has caused severe problems in the treatment of infections. To overcome these difficulties, the advent of a new chemical class of antibacterial drug is eagerly desired. We aimed at creating novel antibacterial agents against bacterial type II topoisomerases, which are well-validated targets. TP0480066 (compound 32) has been identified by using structure-based
耐多药病原体的全球增加在感染的治疗中引起了严重的问题。为了克服这些困难,迫切需要新的化学类别的抗菌药物的出现。我们旨在创建针对细菌II型拓扑异构酶的新型抗菌剂,这些细菌是经过充分验证的靶标。TP0480066(化合物32)已经通过使用基于铅化合物1的基于结构的优化进行了鉴定,该结构是我们先前的铅鉴定研究的结果。TP0480066对耐甲氧西林的金黄色葡萄球菌的MIC 90值(MRSA),耐万古霉素肠球菌(VRE)和基因型耐青霉素肺炎链球菌(gPRSP)分别为0.25、0.015和0.06μg/ mL。因此,TP0480066被认为是该化学类别的有前途的抗菌药物候选者。
