Facile synthesis of new 4-aza-podophyllotoxin analogs via microwave-assisted multi-component reactions and evaluation of their cytotoxic activity
摘要:
A series of new 4-aza-podophyllotoxin analogs containing thiazole unit were synthesized via multi-component reactions of aldehydes, tetronic acid and 2-methylbenzo[d]thiazol-5-amine under microwave irradiation. The method not only provides a valuable tool in design and synthesis of new4-aza-podophyllotoxin analogs but also has the advantages of atom-economy, environmental-friendliness, good yields and operational simplicity. More importantly, the preliminary evaluation on the cytotoxic activity of this type of new 4-aza-podophyllotoxin analogs has resulted in the finding of several compounds with potent and efficacious cytotoxicity to three carcinoma cell lines M14, MCF7 and SW1116.
