isoxazole–based carboxamides 3(a-d); ureates 4(a-g), 5, 6, 7a,b, 8; and hydrazones 9(a-f), 10(a-d), 11a,b as potential inhibitors of VEGFR2. The carboxamides and ureates were synthesized by converting 5-(aryl)-isoxzaole-3-carbohydrazides 1a,b to the corresponding carbonylazides 2a,b followed by treatment with the appropriate amines. The hydrazones were directly obtained through condensation of the carbohydrazide
随后的研究展示了 28 种基于异恶唑的羧酰胺 3(ad) 新化合物的体外抗癌活性结果;脲酸盐 4(ag), 5, 6, 7a,b, 8; 腙 9(af), 10(ad), 11a,b 作为 VEGFR2 的潜在抑制剂。通过将 5-(芳基)-isoxzaole-3-carbohydrazides 1a,b 转化为相应的羰基叠氮化物 2a,b 然后用适当的胺处理来合成羧酰胺和脲酸酯。腙直接通过碳酰肼 1a、b 与醛和/或酮缩合获得。目标化合物的结构通过元素和光谱分析得到确认。溶液的初步体外抗癌筛选(10 -5 M) 对 60 种癌细胞系(NCI,美国)的研究表明,羧酰胺 3c 是最有希望的生长抑制剂。明确地,3c 在 10µM 时显示出针对白血病(HL-60(TB)、K-562 和 MOLT-4)、结肠癌 (KM12) 和黑色素瘤 (LOX IMVI) 细胞系的有效抗癌活性,%GI 范围 = 70
