权利人:SHANGHAI HUALI BIOMEDICAL CO LTD
摘要:The invention discloses CA-4 antitumour drug, their synthetic methods and applications. The CA-4 antitumour drug are obtained by introducing an alkoxy group or a fluorine-containing alkoxy group at the 4′ position of the natural product Combretastatin and modified with a functional chemical group at its 3′ position. The CA-4 derivated anti-tumor drugs of the invention have inhibitory ability on two targets related to tubulin and arylsulfatase, and can be used for anti-tumor treatment. t,?
