我们报道了针对两种戊烯基转移酶:十一戊烯基二磷酸合成酶(UPPS)和脱氢角鲨烯合成酶(CrtM)的抗菌先导物酮酸和二酮酸的发现。酮酸和二酮酸结合到HIV-1整合酶的活性位点Mg2+/Asp结构域,并且类似的结构域存在于戊烯基转移酶中。我们报道了一种双酮酸和一种酮酸与CrtM结合的x射线晶体结构,支持Mg2+结合假说,以及一种双酮酸与UPPS结合的x射线结构。在所有情况下,抑制剂结合到法尼酯二磷酸底物结合位点。化合物45对金黄色葡萄球菌的MIC90值为~250 ~ 500 ng/mL,对炭疽芽孢杆菌的MIC90值为500 ng/mL,对单核增生李斯特菌和屎肠球菌的MIC90值为4 μg/mL,对化脓性链球菌M1的MIC90值为1 μg/mL,对大肠杆菌(DH5α、K12)和人细胞系的MIC90值均无明显抑制作用。
We report the discovery of antibacterial leads, keto- and diketo-acids, targeting two prenyl transferases: undecaprenyl diphosphate synthase (UPPS) and dehydrosqualene synthase (CrtM). The leads were suggested by the observation that keto- and diketo-acids bind to the active site Mg2+/Asp domain in HIV-1 integrase, and similar domains are present in prenyl transferases. We report the x-ray crystallographic structures of one diketo-acid and one keto-acid bound to CrtM, which supports the Mg2+ binding hypothesis, together with the x-ray structure of one diketo-acid bound to UPPS. In all cases, the inhibitors bind to a farnesyl diphosphate substrate-binding site. Compound 45 had cell growth inhibition MIC90 values of ~250–500 ng/mL against S. aureus, 500 ng/mL against Bacillus anthracis, 4 μg/mL against Listeria monocytogenes and Enterococcus faecium, and 1 μg/mL against Streptococcus pyogenes M1, but very little activity against E. coli (DH5α, K12) or human cell lines.
