The design, synthesis and biological evaluations of fourteen 4-substituted 2,6-dimethylfuro[2,3-d]pyrimidines are reported. Four compounds (11–13, 15) inhibit vascular endothelial growth factor receptor-2 (VEGFR-2), platelet-derived growth factor receptor β (PDGFR-β), and target tubulin leading to cytotoxicity. Compound 11 has nanomolar potency, comparable to sunitinib and semaxinib, against tumor cell
报道了14 种 4-取代 2,6-二甲基呋喃并[2,3- d ]嘧啶的设计、合成和生物学评价。四种化合物 ( 11 – 13 , 15 ) 抑制血管内皮生长因子受体 2 (VEGFR-2)、血小板衍生生长因子受体 β (PDGFR-β) 和导致细胞毒性的靶微管蛋白。化合物11对于过表达 VEGFR-2 和 PDGFR-β 的肿瘤细胞系具有纳摩尔级效力,与舒尼替尼和塞马西尼相当。此外,11与微管蛋白上的秋水仙碱位点结合,解聚细胞微管并抑制纯化的微管蛋白组装,克服 βIII-微管蛋白和 P-糖蛋白介导的耐药性,并启动有丝分裂停滞,导致细胞凋亡。在体内,其HCl盐21减少了异种移植和同种异体移植小鼠模型中的肿瘤大小和血管分布,并且优于多西紫杉醇和舒尼替尼,并且没有明显的毒性。因此,21提供了潜在的单一药物联合化疗。
