  Discovery of novel 2-(3-(2-chlorophenyl)pyrazin-2-ylthio)-N-arylacetamides as potent HIV-1 inhibitors using a structure-based bioisosterism approach

  摘要：

  The present work is an extension of our ongoing efforts towards the development and identification of new molecules with anti-HIV activity which have previously led to the discovery of arylazolylthioacetanilides as highly active NNRTIs. In this article, a series of 2-2-(3-(2-chlorophenyl)pyrazin-2-ylthio)-N-arylacetamide derivatives were synthesized and evaluated for in vitro anti-HIV activity. Most of the tested compounds exhibited moderate activities against wild-type HIV-1. Among them, compound 6k showed significant activity against wild-type HIV-1 with an EC50 value of 1.7 mu M, along with moderate activity against wild-type reverse transcriptase (RT). The preliminary structure-activity relationship (SAR) and docking calculations of this new series of compounds were also investigated, which may help designing more potent molecules.

  In continuation of our endeavors to develop new, potent, selective, and less toxic anti-HIV agents, we describe our structure-based bioisosterism design, synthetic strategy, and structure–activity relationship (SAR) studies that led to the identification of pyridazinylthioacetamides, a novel class of NNRTIs, isosteres of arylazolylthioacetanilide derivatives. Nearly all of the tested compounds inhibited HIV-1 strain IIIB replication in the lower micromolar concentration range (EC50: 0.046–5.46 μM). Notably, the most promising compound 8k exhibited extremely potent inhibitory activity against HIV-1 replication with an EC50 value of 0.046 μM, CC50 of 99.9 μM and the viral selectivity index amounted to 2149. These values were much better than those of NVP (EC50 = 0.09 μM) and DDC (EC50 = 1.04 μM). Compound 8k also exhibited moderate inhibition of enzymatic activity with an IC50 value of 4.06 μM, which was of the same order of magnitude as that of NVP (2.74 μM). Docking calculations were also performed to investigate the binding mode of compound 8k into the non-nucleoside binding site of HIV-1 RT and to rationalize some SARs.

  为了继续开发新型、强效、选择性和低毒的抗艾滋病毒药物，我们介绍了基于结构的生物异构设计、合成策略和结构-活性关系（SAR）研究，通过这些研究，我们发现了哒嗪基硫代乙酰胺类化合物，这是一类新型的 NNRTIs，是芳唑基硫代乙酰苯胺衍生物的异构体。几乎所有测试化合物都能在较低的微摩尔浓度范围内抑制 HIV-1 株 IIIB 的复制（EC50：0.046-5.46 μM）。值得注意的是，最有前途的化合物 8k 对 HIV-1 复制具有极强的抑制活性，其 EC50 值为 0.046 μM，CC50 为 99.9 μM，病毒选择性指数为 2149。这些数值远远优于 NVP（EC50 = 0.09 μM）和 DDC（EC50 = 1.04 μM）。化合物 8k 对酶活性也表现出中等程度的抑制作用，其 IC50 值为 4.06 μM，与 NVP（2.74 μM）处于同一数量级。为了研究化合物 8k 与 HIV-1 RT 非核苷结合位点的结合模式，并使一些 SARs 更加合理，还进行了对接计算。

  In continuation of our efforts toward the discovery of potent HIV-1 NNRTIs with novel structures, we have employed a scaffold hopping strategy to explore the chemically diversed space of bioactive compounds. The original arylazolylthioacetanilide platform was replaced with different imidazopyridinylthioacetanilide scaffolds to yield the optimal pharmacophore moieties in order to generate novel NNRTIs with desirable potency. Some of the new compounds proved able to inhibit HIV-1 replication in the low micromolar range. In particular, compound 5b16 displayed the most potent anti-HIV-1 activity (EC50 = 0.21 +/- 0.06 mu M), inhibiting HIV-1 IIIB replication in MT-4 cells more effectively than dideoxycytidine (EC50 = 1.4 +/- 0.1 mu M) and similarly with nevirapine (EC50 = 0.20 +/- 0.10 mu M). Preliminary structure-activity relationship (SAR) of the newly synthesized congeners is discussed, and molecular modeling study is performed to rationalize the SAR conclusions. (C) 2012 Elsevier Ltd.
