Promising anticancer compounds of the type 1,6-disubstituted 4,5,6,7-tetrahydropyrazolo[3,4-c]pyridin-7-ones were identified. The target compounds were readily synthesized in a large scale via a sequence of reactions starting from the commercially available primary amines. Their in vitro anti-proliferative activity has been evaluated on prostate (DU-145), colon (HT-29 and HCT-116) and melanoma (A375P) human cancer cell lines. The relationships between the structure and the anticancer activity, covering all tested cancer cell lines, revealed that the compound 5c with 2,4-dimethylphenyl substituent at $R^2$ was the most potent with the $IC_50}$ values in the range as low as 0.16 to $0.40\mu}M$.
发现了有前景的抗癌化合物,类型为1,6-二取代的4,5,6,7-四氢吡咯并[3,4-c]吡啶-7-酮。这些靶化合物通过一系列反应,从商业可获得的初级胺出发,容易大规模合成。它们在前列腺(DU-145)、结肠(HT-29和HCT-116)以及黑色素瘤(A375P)的人癌细胞系上进行了体外抗增殖活性评估。结构与抗癌活性之间的关系覆盖了所有测试的癌细胞系,结果显示,化合物5c在处具有2,4-二甲基苯取代基,是最有效的,其值低至0.16至<0.40\mu}M>。
