NO donor,well known for its biological functions,has not only the anti-proliferative ability against tumor cells itself,12 but has been reported to have positive synergy with platinum-based drugs on the tumor cells.3-5 However,it is noted that all the previous attempts were performed by administrating NO-donor compounds and platinum drugs as two different agents.We have designed and prepared two series of NO-donors(organic nitrates,furoxans) to combine with platinum-based moieties as anticancer agents to take synergic actions on the tumor cells for the first time.
