kuwanon H

Kuwanon H is a flavonoid isolated from Morus alba, which acts as a potent non-peptide bombesin receptor antagonist. Kuwanon H selectively inhibits binding of gastrin releasing peptide CRP to GRP-preferring recepotr, with a Ki value of 290 nM in cells[1].

ChEBI: A tetrahydroxyflavone isolated from the plant species of the genus Morus.
