  新的喹喔啉衍生物作为双重Pim-1 / 2激酶抑制剂：设计，合成和生物学评价。

  摘要：

  已在多种血液学（例如多发性骨髓瘤或急性骨髓性白血病（AML））和实体（例如结直肠癌）肿瘤中发现了莫洛尼氏鼠白血病病毒（Pim）-1/2激酶过表达的前病毒整合位点，在癌症进展，转移和耐药中起关键作用，并且与不良预后有关。因此，这些激酶被认为是肿瘤学中令人关注的靶标。我们在此报告了新的喹喔啉衍生物作为双重Pim1 / 2抑制剂的设计，合成，结构-活性关系（SAR）和体外评估。两种铅化合物（5c和5e然后确定）为有效的亚微摩尔Pim-1和Pim-2抑制剂。这些分子还能够抑制两种人类细胞系MV4-11（AML）和HCT-116（结肠直肠癌）的生长，并表达高内源性的Pim-1 / 2激酶。

  Synthesis of substituted 2-ethoxycarbonyl- and 2-carboxyquinoxalin-3-ones for evaluation of antimicrobial and anticancer activity

  摘要：

  A series of variously substituted quinoxalin-3-ones bearing an ethoxycarbonyl or carboxy group in the C-2 position has been prepared and their structures proved by H-1 NMR spectroscopy. The obtained compounds were investigated in vitro for antimicrobial and anticancer activities. Preliminary results showed a moderate activity against a few strains of bacteria but no significant anticancer and anti-HIV activity. (C) 1998 Elsevier Science S.A. All rights reserved.
