实验参考方法

Target	EC50: 32 nM (IBa)[1]
In Vitro	(±)-Bay K 8644, a conventional racemic mixture of Bay K 8644, is widely used as an L-type Ca2+ channel agonist. Each optical isomer possesses opposite effects on IBa (R(+)-Bay K 8644 as an antagonist and Bay-K-8644 (S)-(-)- as an agonist. Bay-K-8644 (S)-(-)- can prevent the inhibitory actions of two distinct cyclic nucleotide pathways on IBa in gastric myocytes of the guinea pig antrum[1]. The Ca2+ channel activity is enhanced by 3–30 μM Bay-K-8644 (S)-(-)-, an agonist of L-type Ca2+ channels[2]. The interactions of two Ca2+ channel activators Bay-K-8644 (S)-(-)- and FPL 64176 is examined on smooth muscle L-type Ca2+ channels. FPL 64176 (300 nM) causes a sustained contraction of rat tail artery strips. This contractile response is inhibited by approximately 70% by Bay-K-8644 (S)-(-)- (EC50=14 nM). Bay-K-8644 (S)-(-)- (100 nM) increases whole-cell Ca2+ currents in A7r5 smooth muscle cells but effectively blocks further stimulation by 1 μM FPL 64176[3].
