the allosteric hydrophobic back pocket in a type III inhibitors-like binding mode. The binding interaction is augmented by a ring substituent with long chain extension at position 1 of the benzimidazole due to its hydrophobic interaction with the hydrophobic side chains of the amino acids at the interface between the ATP binding site and the allosteric back pocket.

通过抑制血管内皮生长因子受体2(VEGFR-2)抑制血管生成已被应用于癌症治疗,因为它在促进癌症生长和转移中起着重要的作用。在本研究中,通过简便的合成途径设计并合成了一系列苯并咪唑-呋喃杂种。评估合成的化合物对乳腺癌(MCF-7)和肝细胞癌(HepG2)癌细胞的体外细胞毒活性。与他莫昔芬(IC50 = 21.57μM)相比,两种合成的缀合物10b和15对MCF-7细胞系表现出有效的抗增殖特性(分别为IC50 = 21.25、21.35μM)。此外,化合物10a,10b,15和17还显示出有希望的效价(IC50 = 25.95、22.58、26.94和31.06μM,与顺铂相反(分别为IC50 = 31.16μM)针对肝癌细胞HepG2。而且,对合成化合物对MCF-7细胞系中VEGFR-2水平的影响的体外评价显示出相对于未处理的对照细胞,它们具有有效的抑制活性。四种化合物10a,10b,14
