Design, synthesis, and biological evaluation of novel alkylsulfanyl-1,2,4-triazoles as cis-restricted combretastatin A-4 analogues
文摘
32 novel 1,2,4-triazole derivatives were designed and synthesized as cis-restricted combretastatin A-4 analogues. Antiproliferative activity of these compounds was evaluated. Analogues 20 and 25 exhibited much stronger antitumor activity than CA-4. Flow-activated cell sorting analysis suggested that compound 20 mainly arrested PC-3 cells in G2/M stage.
