“ Formononetin (10 and 100 μmol/L) reduced the change rate of Ca2+-fluorescence intensity in response to KCl (50 mmol/L).”
“Under conditions of endothelium denudation, formononetin (10, 30, and 100 μmol/L) inhibited the contraction induced by KCl and that induced by CaCl2 in Ca2+-free depolarized medium.”
