embryonic kidney cell line. Targeting of isoprenoid biosynthesis is involved with 74 having IC50 values of ∼100 nM against heptaprenyl diphosphate synthase and 200 nM against farnesyl diphosphate synthase. B. subtilis growth inhibition was rescued by addition of farnesyl diphosphate, menaquinone-4 (MK-4), or undecaprenyl phosphate (UP), and the combination of MK-4 and UP resulted in a 25× increase in ED50,
我们报告说烷基取代的双膦酸盐具有抗炭疽芽孢杆菌(0.40μg/ mL),耻垢分枝杆菌(1.4μg/ mL),枯草芽孢杆菌(1.0μg/ mL)和金黄色葡萄球菌(13μg/ mL)的活性。在许多情况下,没有血清结合作用,也没有针对人类胚胎肾细胞系的低活性。异戊二烯生物合成的目标涉及74个抗庚二烯基二磷酸合酶的IC50值为〜100 nM,抗法呢基二磷酸合酶的IC50值为〜200 nM。枯草芽孢杆菌的生长抑制可通过添加法呢基二磷酸酯,甲萘醌4(MK-4)或十一碳烯基磷酸酯(UP)来挽救,MK-4和UP的组合导致ED50升高25倍,表明靶向醌和细胞壁的生物合成。艰难梭菌被74抑制,并且由于该生物体不合成醌,因此细胞壁生物合成可能成为目标。我们还解决了与八烯丙基二磷酸和/或十一碳烯基二磷酸合酶结合的抑制剂的三种X射线结构。
