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.

Novel series of sometriazolo[4,3-b]pyridazine derivatives were designed and synthesized. All the newlysynthesized compounds were evaluated for their cytotoxic activity at 10−5 M concentration towards 60 cancer cell lines according to USA NCI protocol. Most of the synthesized compounds showed good activity against SR (leukemia) cell panel. The most active compounds, 2f and 4a were subjected for further
设计并合成了一些新的三唑并[4,3- b ]哒嗪衍生物系列。 根据USA NCI方案,评估所有新合成的化合物在10 -5 M浓度下对60种癌细胞系的细胞毒活性。大多数合成的化合物显示出对SR(白血病)细胞的良好活性。活性最强的化合物2f和4a在5个剂量水平的筛选下进行了进一步评估,并在体外确定了其对c-Met激酶抑制的功效。通过分子对接探索了这些衍生物的结合方式。

of two new and unusual classes of heterocycles, possessing structural similarities to the broad spectrum antibiotic fervenulin, were synthesized and examined for in vitro antimicrobial activity. Only three of 17 mesoionicpyrimido[1,2-b]pyridazine-2,4-diones exhibited evidence of antimicrobial activity while seven of eight mesoionicpyridazino[2,3-a]-s-triazine-2,4-diones were active against one or more
