binding of compounds and targets. Guided by the analysis of binding interactions, a total of 10 novel VEGFR-2 inhibitors based on N-methyl-4-oxo-N-propyl-1,4-dihydroquinoline-2-carboxamide scaffold were discovered through fragment-based drug design and structure-based virtual screening, which expands the chemical space of current VEGFR-2 inhibitors. Biological activity evaluation showed that even though
作为异常血管生成相关肿瘤治疗的有效靶点,VEGFR-2具有各种支架的小分子抑制剂,已被批准用于治疗肾脏癌,非小细胞肺癌等疾病。但是,内源性和获得性耐药是仍被认为是VEGFR-2临床候选药物失败的主要因素。因此,市场上仍然迫切需要开发新型的VEGFR-2抑制剂,但也具有挑战性。在这项工作中,包括Asp1046,Ile1025,HIS1026,Cys919和Lys868在内的残基被确定为Hbonded相互作用的最重要残基,而His1026,Asp1046,Glu885,Ile1025和Leu840则通过对蛋白质的全面分析而发挥了关键作用。配体相互作用 在化合物和靶标的结合中起关键作用。在结合相互作用分析的指导下,共有10种新的VEGFR-2抑制剂基于通过基于片段的药物设计和基于结构的虚拟筛选,发现了N-甲基-4-氧代-N-丙基-1,4-二氢喹啉-2-羧酰胺支架,从而扩展了目前的VEGFR-
