  Synthesis and biological evaluation of naphthoquinone analogs as a novel class of proteasome inhibitors

  摘要：

  Screening of the NCI Diversity Set-1 identified PI-083 (NSC-45382) a proteasome inhibitor selective for cancer over normal cells. Focused libraries of novel compounds based on PI-083 chloronaphthoquinone and sulfonamide moieties were synthesized to gain a better understanding of the structure-activity relationship responsible for chymotrypsin-like proteasome inhibitory activity. This led to the demonstration that the chloronaphthoquinone and the sulfonamide moieties are critical for inhibitory activity. The pyridyl group in PI-083 can be replaced with other heterocyclic groups without significant loss of activity. Molecular modeling studies were also performed to explore the detailed interactions of PI-083 and its derivatives with the beta 5 and beta 6 subunits of the 20S proteasome. The refined model showed an H-bond interaction between the Asp-114 and the sulfonamide moiety of the PI-083 in the beta 6 subunit. (C) 2010 Elsevier Ltd. All rights reserved.

  PI3Kα/mTOR ATP-competitive inhibitors are considered as one of the promising molecularly targeted cancer therapeutics. Based on lead compound A from the literature, two similar series of 2-substituted-4-morpholino-pyrido[3,2-d]pyrimidine and pyrido[2,3-d]pyrimidine analogs were designed and synthesized as PI3Kα/mTOR dual inhibitors. Interestingly, most of the series gave excellent inhibition for both

  PI3Kα/ mTOR ATP竞争性抑制剂被认为是有前途的分子靶向癌症治疗剂之一。基于文献中的铅化合物A，设计并合成了两个相似的2-取代-4-吗啉代-吡啶并[3,2- d ]嘧啶和吡啶并[2,3- d ]嘧啶类似物系列，并将其合成为PI3Kα/ mTOR dual抑制剂。有趣的是，大多数系列均对两种酶均具有优异的抑制作用，IC 50值范围从一位到两位数nM。与许多PI3Kα/ mTOR双重抑制剂不同，我们的化合物显示出对PI3Kα的选择性。基于其强大的酶抑制活性，对PI3Kα的选择性以及在2D细胞培养活力测定中良好的治疗指数，化合物4h选择在3D培养中评估其针对MCF7乳腺癌细胞的IC 50以及与这两种酶的对接研究。

  The dual PI3Kα/ m TOR inhibitors represent a promising molecularly targeted therapy for cancer. Here, we documented the discovery of new 2,4-disubstituted quinazoline analogs as potent dual PI3Kα/sm TOR inhibitors. Our structure based chemistry endeavor yielded six excellent compounds 9e, 9f, 9g, 9k, 9m, and 9o with single/double digit nanomolar IC50 values against both enzymes and acceptable aqueous

  双 PI3Kα/m TOR 抑制剂代表了一种有前途的癌症分子靶向治疗。在这里，我们记录了新的 2,4-二取代喹唑啉类似物作为有效的双重 PI3Kα/sm TOR 抑制剂的发现。我们基于结构的化学努力产生了六种优异的化合物9e、9f、9g、9k、9m和9o，其对两种酶的IC 50值为单位/两位数，并且具有可接受的水溶性和氧化代谢稳定性。其中一种类似物9m具有磺酰胺取代基，以前没有描述过这种化学支架。短直接合成路线，构效关系，体外描述了针对正常成纤维细胞和 3 个乳腺癌细胞系的 2D 细胞培养活力测定，以及针对该系列的 MCF7 细胞的体外3D 培养活力测定。
