years. Accordingly, in this study, the synthesis of two new pyrazoles, six 1,3,4-oxadiazoles, four 1,3,4-thiadiazoles, and ten 1,2,4-triazole-3-thione derivatives having structural characteristics similar to sorafenib was carried out. A preliminary screening of synthesized compounds and known inhibitors sorafenib and staurosporine at 10 µM concentration on in vitro activity of VEGFR-2 was performed, and
血管内皮生长因子受体2(VEGFR-2)是一种受体酪氨酸激酶,已知在包括乳腺癌在内的多种恶性肿瘤中异常表达,并被认为是肿瘤血管生成最重要的贡献者之一。索拉非尼是近年来获得美国FDA批准临床使用的众多VEGFR-2抑制剂之一。因此,在本研究中,合成了两种新的吡唑、六种1,3,4-恶二唑、四种1,3,4-噻二唑和十种1,2,4-三唑-3-硫酮衍生物,其结构特征类似于进行了索拉非尼治疗。对合成化合物和已知抑制剂索拉非尼和十字孢菌素在 10 µM 浓度下对VEGFR-2体外活性进行了初步筛选,化合物10c、8a、和11g被鉴定为最有效的衍生物,其%VEGFR-2残余活性低于30%,并且进行剂量依赖性抑制研究以确定这些抑制剂的IC 50 值。化合物10c被发现是最有效的 VEGFR-2 活性抑制剂,IC 50值为 0.664 µM。针对乳腺癌 (MCF-7) 细胞系、三阴性人乳腺癌 (MDA-MB-231)
