  • Title: Effects of calcium channel blockers on steroidogenesis stimulated by ACTH and cAMP in isolated rat adrenal cells.
    Author: Matsuki M, Watanabe S, Ikeda M, Nishida S, Saito T.
    Journal: Horm Metab Res; 1996 Aug; 28(8):374-6. PubMed ID: 8886822.
    Abstract:
    The effects of the calcium channel blockers verapamil, diltiazem, prenylamine and nifedipine on the ACTH- and cAMP-mediated pathway for steroidogenesis in a suspension solution of isolated rat adrenal cells were studied. Steroidogenesis stimulated by ACTH (10(-10) M) or cAMP (10(-3) M) was not inhibited by nifedipine (10(-4) M), but was strongly inhibited in a concentration-dependent manner by verapamil, diltiazem and prenylamine (10(-5) to 10(-4) M).
