摘要
Human N-type Ca2+ channels were rapidly and reversibly inhibited by 5-100 mu M BW619C89 (IC50 = 16.4 mu M at V-test = + 10 mV and V-hold = -90 mV). In the presence of 20 mu M BW619C89, activation kinetics were significantly faster. The degree of inhibition observed was affected by both test and holding potential, indicating state-dependent interactions with the N-type Ca2+ channel. (C) 1998 Elsevier Science Ltd.
