Identification of a novel antiangiogenic agent; 4-(N-Imidazol-2-ylmethyl)amino benzopyran analogues
摘要:
A series of 4-(N-imidazol-2-ylmethyl)aminobenzopyran analogues, originally designed as K-ATP openers for ischemic diseases, showed antiangiogenic properties through the inhibition of HUVEC tube formation. Especially one of p-Cl substituted analogues (4c) completely inhibited HUVEC tube formation at 10 muM. The compound 4c significantly inhibited tumor growth by 52% on A549 (human non small cell lung carcinoma) in nude mice xenografts without any significant side effects. (C) 2003 Elsevier Science Ltd.
