Axl 通常在许多癌症中过度表达,并与肿瘤生长、转移、耐药性和较差的总体生存率相关,因此已成为癌症治疗的一个有前景的靶点。然而,用于 Axl 抑制的新化学形式的可用性是有限的。在此,我们介绍了新型 Axl 抑制剂的开发和表征,包括一系列二苯基嘧啶二胺衍生物的设计、合成和构效关系 (SAR)。这些化合物中的大多数都表现出显着的抗 Axl 激酶活性。特别是,有前途的化合物m16显示出最高的酶抑制效力(IC 50 = 5 nM)并阻断多种肿瘤细胞的增殖效力( 42 个癌细胞系中 4 个的CC 50 <100 nM)。此外,化合物m16还具有较好的药代动力学特征和肝微粒体稳定性。所有这些有利的结果使m16成为进一步开发的良好领先治疗候选药物。

Abstract Present manuscript describes the synthesis and molecular structure features of novel condensed pyrido[1,2-a]quinazolines. The above-mentioned compounds were synthesized via condensation of 2-[azolyl-(аzinyl-)]anilines with 5-oxohexanoic acid. The tandem condensation intermediates were isolated and cyclized under various conditions. The structures of synthesized compounds were confirmed by

The synthesis of novel pyrrolo[1,2‐a]azolo‐(azino‐)[c]quinazolines by tandem reaction of 2‐(azolyl‐(azinyl‐))anilines with oxocarboxylic acids was described in this article. The mechanism of obtained compounds formation was proposed, and the intermediate of the heterocyclization has been isolated and characterized. The IR‐, 1H and 13C NMR‐, chromato‐mass spectra of synthesized compounds were studied

The structure-activity relationship of 2'-pyrrole, pyrazole and triazole substituted 2-(anilinomethyl)imidazolines as alpha(1) adrenergic agonists was investigated. The size and orientation of substituents, as well as the position of the heteroatoms, were found to have a profound effect on the potency and selectivity of the molecules. Potent alpha(1A) subtype selective agonists have been identified. (C) 2003 Elsevier Science Ltd. All rights reserved.
