Postsynaptic inhibitory effects of phenothiazines at cholinergic synapses may not involve calmodulin


Treatment of frog cutaneous-pectoris nervemuscle preparations with calmidazolium (R 24571), a calmodulin-inhibitor, at concentrations of 2×10−7 mol/l and 5×10−7 mol/l had no discernable effect on MEPP amplitude. 10−6 mol/l calmidazolium caused a small (10–35%) increase in MEPP amplitude in most preparations. The phenothiazine calmodulin-inhibitor… (More)
