A series of novel imperatorin derivatives were synthesized from commercially available xanthotoxin. The in vitro pharmacological evaluation indicated that all of the compounds possessed potent vasodilatory activity. Among them, compounds (5b), (5d) and (5e) exhibited higher vasdilatory activity (with EC50 values of 0.68 μM, 0.59 μM and 0.49 μM, respectively) than imperatorin (EC50 = 1.12 μM). The program Volsurf was used to predict the derivatives' ADME relevant descriptors. The results suggested that these novel compounds had a potential interest for the development of novel and potent vasorelaxant agents.
