Dihydropyridines (+)-PN200-110 and (+/-)-Bay-K-8644 inhibit or potentiate, respectively, catecholamine release evoked by DMPP- or K-stimulation of perfused cat adrenal glands. Since both, secretion of adrenaline and noradrenaline are equally affected, and these two drugs specifically act on voltage-dependent chromaffin Ca channels, it seems that secretion of each amine from their respective cell is regulated by the same type of channel.
二氢吡啶类化合物(+)-PN200-110和(±)-Bay-K-8644分别抑制或增强了灌注猫肾上腺经DMPP或钾刺激诱发的儿茶酚胺释放。由于肾上腺素和去甲肾上腺素的分泌均受到同等影响,且这两种药物特异性作用于电压依赖性嗜铬细胞钙通道,因此似乎每种胺从其各自细胞的分泌是由同一类型的通道调节的。
