A series of novel substituted 3,6-disubstituted pyridazines based on the structure of vatalanib (PTK787) were designed and synthesized. The cytotoxicity of the final compounds was tested in vitro on HT-29 colon cancer cell line. Compounds 2a and 2b with 4-chlorophenylamino moiety, exerted the highest cytotoxic activity with IC50 values equal to 15.3 and 3.9 μM respectively. The most promising compound, 2b, was found to be about fivefold more active than vatalanib against HT-29 colon cancer cell line.
根据 vatalanib(PTK787)的结构设计并合成了一系列新型取代的 3,6-二取代哒嗪类化合物。最终化合物的细胞毒性在 HT-29 结肠癌细胞株上进行了体外测试。带有 4-氯苯胺基的化合物 2a 和 2b 具有最高的细胞毒性活性,IC50 值分别为 15.3 和 3.9 μM。研究发现,最有前途的化合物 2b 对 HT-29 结肠癌细胞株的活性是 vatalanib 的五倍。
