coli FabH (ecFabH), but not Mycobacterium tuberculosis FabH (mtFabH) or Plasmodium falciparum KASIII (PfKASIII). The activity against ecFabH ranges from 0.9 to >100microM and follows a consistent general SAR trend. Many of the compounds were shown to have antimalarial activity against chloroquine (CQ)-sensitive (D6) P. falciparum (IC(50)=5.3microM for the most potent inhibitor) and some were active against
已经合成了一系列环状砜,并且已经研究了它们对β-酮酰基-ACP合酶III(FabH)的活性。这些化合物对大肠杆菌FabH(ecFabH)具有选择性活性,但对结核分枝杆菌FabH(mtFabH)或恶性疟原虫KASIII(PfKASIII)没有选择性。针对ecFabH的活性范围从0.9到> 100microM,并遵循一致的一般SAR趋势。已显示许多化合物对氯喹(CQ)敏感(D6)恶性疟原虫具有抗疟疾活性(最有效的抑制剂,IC(50)= 5.3microM),有些对大肠杆菌具有活性(MIC = 6.6microg)。 / ml(最有效的抑制剂)。
