  Synthesis and biological evaluation of imidazo[1,2-a]pyridine derivatives as novel PI3 kinase p110α inhibitors

  摘要：

  3-{1-[(4-Fluorophenyl)sulfonyl]-1H-pyrazol-3-yl}-2-methylimidazo[1,2-a]pyridine, 2a, was discovered in our chemical library as a novel p110 alpha inhibitor with an IC50 of 0.67 mu M, through screening in a scintillation proximity assay. Optimization of the substituents of 2a increased the p110 alpha inhibitory activity by more than 300-fold (2g: IC50 = 0.0018 mu M). Further structural modification of 2g afforded thiazole derivative 12, which has potent p110 alpha inhibitory activity (IC50 of 0.0028 mu M) and is highly selective for p110 alpha over other PI3K isoforms. Compound 12 also inhibited serum-induced cell proliferation of A375 and HeLa cells in vitro with IC50 values of 0.14 mu M and 0.21 mu M, respectively, and suppressed tumor growth by 37% in a mouse HeLa xenograft model when dosed intraperitoneally at 25 mg/kg. These results suggest that selective p110 alpha inhibitors may have potential as cancer therapeutic agents. (c) 2006 Elsevier Ltd. All rights reserved.

  which can be modified without compromising compounds’ potency. Thus modified compounds are micromolar inhibitors of Rab11A prenylation, simultaneously being inactive against Rap1A/Rap1B modification, with the ability to inhibit proliferation of the HeLa cancer cell line. These findings were rationalized by molecular docking, which recognized interaction of phosphonic and carboxylic groups as decisive

  Rab GTPase家族的成员是囊泡运输的主要监管者。当失调时，它们与许多病理状态相关。抑制RGGT（一种负责Rab GTPases的翻译后香叶基香叶基化反应的酶）代表了一种控制这些蛋白活性的方法。由于调节RGGT的分子数量有限，因此我们将分子建模与生物学分析相结合，以确定首次报道的RGGT抑制剂膦酰基羧酸酯的修饰方式如何合理地增进对它们的结构-活性关系的了解。我们已经确定了咪唑[1,2- a]吡啶环，可在不影响化合物效能的情况下对其进行修饰。如此修饰的化合物是Rab11A异戊烯基化的微摩尔抑制剂，同时对Rap1A / Rap1B修饰无活性，并具有抑制HeLa癌细胞系增殖的能力。这些发现通过分子对接得到合理化，分子对接认为膦酸和羧基的相互作用对于RGGT结合位点的膦酰基羧酸酯定位起决定性作用。
