methoxsalen A naturally occurring substance isolated from the seeds of the plant Ammi majus with photoactivating properties. As a member of the family of compounds known as psoralens or furocoumarins, methoxsalen's exact mechanism of action is unknown; upon photoactivation, methoxsalen has been observed to bind covalently to and crosslink DNA. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
