  Diketo Acids Derivatives as Dual Inhibitors of Human Immunodeficiency Virus Type 1 Integrase and the Reverse Transcriptase RNase H Domain

  摘要：

  HIV-1 整合酶（IN）和逆转录酶（RT）是病毒循环中的重要酶。RT 对 RNA 病毒基因组的逆转录至关重要，而 IN 则参与将 RT 产生的前病毒双链 DNA 插入宿主染色体。这种酶有两种相关功能：RNA 和 DNA 依赖性 DNA 聚合酶（RDDP 和 DDDP）以及核糖核酸酶 H（RNase H）。RNase H 的功能是催化选择性水解 RNA:DNA 异源双工复制中间体的 RNA 链。自从发现 HIV-1 RNase H 和 IN 的催化核心以非常相似的方式折叠，具有非常相似的活性位点几何结构，并显示出催化活性绝对需要的相同 DDE 三元组之后，一些研究人员致力于 IN 和 RNase H 双抑制剂的研究。我们对 IN 抑制剂的设计和合成有着长达十年的兴趣，这促使我们研究我们的化合物对 RNase H 的活性。报告和讨论了吡咯基和醌基二酮酸的活性结果。

  Rational modification of semaxanib and sunitinib for developing a tumor growth inhibitor targeting ATP binding site of tyrosine kinase

  摘要：

  Analysis of the crystal structure of tyrosine kinase in complexation with an ATP analogue, supplemented with the molecular docking studies of semaxanib and sunitinib in the ATP binding site of the enzyme enabled us to make design of a series of tyrosine kinase inhibitors. The combination of pyrrole and indolinone in one molecule and placement of appropriate substituent thereof made the molecule compatible for the hydrophobic sub-pocket of the enzyme. Screening of the compounds over 60 cell line panel of human tumor cell lines identified compound 3a that exhibited GI(50) 35 nM and 63 nM against MCF7 and MDA-MB-468 cell lines of breast cancer.

  The increasing efficiency of HAART has helped to transform HIV/AIDS into a chronic disease. Still, resistance and drug drug interactions warrant the development of new anti-HIV agents. We previously discovered hit 6, active against HIV-1 replication and targeting RNase H in vitro. Because of its diketo-acid moiety, we speculated that this chemotype could serve to develop dual inhibitors of both RNase H and integrase. Here, we describe a new series of 1-benzyl-pyrrolyl diketohexenoic derivatives, 7a-y and 8a-y, synthesized following a parallel solution-phase approach. Those 50 analogues have been tested on recombinant enzymes (RNase H and integrase) and in cell-based assays. Approximately half (22) exibited inhibition of HIV replication. Compounds 7b, 7u, and 8g were the most active against the RNase H activity of reverse-transcriptase, with IC50 values of 3, 3, and 2.5 mu M, respectively. Compound 8g was also the most potent integrase inhibitor with an IC50 value of 26 nM.

  Highly active anti-retroviral therapy (HAART) using reverse transcriptase (RT) and protease (PR) inhibitors and, more recently, inhibitors of the fusion is currently the best clinical approach in combating acquired immunodeficiency syndrome (AIDS), caused by infection from human immunodeficiency virus type 1 (HIV-1). However, this therapy does not completely eradicate the virus, so that resistant strains easily emerge. The above problem calls urgently for research on inhibitors of further viral targets such as integrase (IN), the third enzyme produced by HIV. Recently, our research group was engaged in studies on conformationally restrained cinnamoyl compounds related to curcumin as anti-IN agents. Compounds containing both a 3,4,5-trihydroxyphenyl group and a carboxylic acid function were potent IN inhibitors active against viral replication. More recently, a promising new class of inhibitors synthesized by Merck Company has emerged, which contain aryldiketoacid (ADK) functionality. The ADKs selectively inhibited the stand transfer (ST) step of integration and were proven to be effective IN inhibitors in vivo. Our interest in the field of IN inhibitors led us to design pyrrole and indole derivatives containing both a cinnamoyl moiety and a diketoacid group. A number of the cited derivatives were proven potent IN inhibitors, which selectively inhibited the ST step at submicromolar concentrations and were effective against virus replication in HIV-1 infected cells.
