  源自喹诺酮类抗生素的新型 HIV-1 整合酶抑制剂。

  摘要：

  病毒酶整合酶对于 1 型人类免疫缺陷病毒 (HIV-1) 的复制至关重要，并且是抗逆转录病毒药物的剩余目标。在这里，我们描述了喹诺酮类抗生素的修饰，以生产新型整合酶抑制剂 JTK-303 (GS 9137)，该抑制剂阻止病毒酶的链转移。它具有喹诺酮类抗生素的核心结构，在链转移试验中的 IC50 为 7.2 nM，在急性 HIV-1 感染试验中的 EC50 为 0.9 nM。

  The 3-ethoxycarbonyl-4-quinolone compound I has previously been identified via a database search as an interesting lead compound for ligand binding at the benzodiazepine site of GABA(A) receptors (Kahnberg et al. J. Mol. Graphics Modelling 2004, 23, 253-261). Pharmacophore-guided optimization of this lead compound yielded a number of high-affinity ligands for the benzodiazepine site including compounds 20 and 23-25 displaying sub-nanomolar affinities. A few of the compounds have been tested on the alpha(1)beta(2)gamma(2s) and alpha(3)beta(2)gamma(2s) GABA(A) receptor subtypes, and two of the compounds (5 and 19) display selectivity for alpha(1) versus alpha(3)-containing receptors by a factor of 22 and 27, respectively. This selectivity for alpha(1)beta(2)gamma(2s) is in the same range as that for the well-known alpha(1) subunit selective compound zolpidem.
• Investigating the Role of Metal Chelation in HIV-1 Integrase Strand Transfer Inhibitors

  HIV-1 integrase (IN) has been validated as an attractive target for the treatment of HIV/AIDS. Several studies have confirmed that the metal binding function is a crucial feature in many of the reported IN inhibitors. To provide new insights on the metal chelating mechanism of IN inhibitors, we prepared a series of metal complexes of two ligands (HL1 and HL2), designed as representative models of the clinically used compounds raltegravir and elvitegravir. Potentiometric measurements were conducted for HL2 in the presence of Mg(II), Mn(II), Co(II), and Zn(II) in order to delineate a metal speciation model. We also determined the X-ray structures of both of the ligands and of three representative metal complexes. Our results support the hypothesis that several selective strand transfer inhibitors preferentially chelate one cation in solution and that the metal complexes can interact with the active site of the enzyme.
