In order to search for new antitumor drugs with high efficiency and low toxicity, 5- and 6-substituted indazole compounds were designed and synthesized. The antiproliferative activity of target compounds in four human cancer cells, PC-3 (human prostate cancer cell), MCF-7 (human breast cancer cell), HepG-2 (human hepatoma cell) and MGC-803 (human gastric cancer cell), was evaluated by thiazole blue (MTT) method. The results showed that most of the compounds had specific antiproliferative activity against PC-3. Among them, N-((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)-1-isopropyl-1H-in- doleazole-5-carboxyamide (8a) and N-((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)-1-isopropyl-1H-indoleazole-6-formamide (14a) possess strong antitumor activity against PC-3 with IC50 values of 6.21 and 6.43 μmol/L, respectively. It provides a new idea for the research of anti-tumor drugs for prostate cancer.
Key words: indazole; cancer; antiproliferative activity; prostatic cancer
