Diltiazem 104-113 calmodulin 1 Homo sapiens 21-31 2964236-0 1988 Verapamil, diltiazem and nifedipine interactions with calmodulin stimulated (Ca2+ + Mg2+)-ATPase. Diltiazem 11-20 calmodulin 1 Homo sapiens 54-64 2964236-1 1988 The functional interactions of the three prototype Ca2+ antagonists, verapamil, diltiazem and nifedipine, were examined in relation to the calmodulin regulated plasma membrane Ca2+ pump ATPase. Diltiazem 80-89 calmodulin 1 Homo sapiens 139-149 2964236-4 1988 Half-maximal activation by 6 nM calmodulin was antagonized by 10(-3) M verapamil and 10(-3) M diltiazem 25.1 and 12.1% respectively. Diltiazem 94-103 calmodulin 1 Homo sapiens 32-42 3038124-3 1987 Of the four Ca2+ entry blockers tested, only verapamil and diltiazem specifically inhibited the calmodulin-stimulated (Ca2+ + Mg2+)-ATPase activity, the basal enzyme activity being unaltered by these drugs. Diltiazem 59-68 calmodulin 1 Homo sapiens 96-106 3038124-5 1987 Calmodulin concentration effect curves showed the inhibition by verapamil (10(-3) M) and diltiazem (10(-3) M) to be non-competitive. Diltiazem 89-98 calmodulin 1 Homo sapiens 0-10 3484629-6 1986 The concentrations of unlabeled bepridil, W-7, prenylamine, verapamil and diltiazem producing 50% inhibition (IC50) of the binding of [3H]bepridil to calmodulin were 4 microM, 28 microM, 45 microM, 130 microM and 700 microM, respectively. Diltiazem 74-83 calmodulin 1 Homo sapiens 150-160 6847674-3 1983 Hydrophobic ligands including the calmodulin antagonist, R24571 and Ca2+ antagonists, prenylamine and diltiazem, bind to calmodulin and potentiate felodipine binding by as much as 20 fold. Diltiazem 102-111 calmodulin 1 Homo sapiens 121-131 6747823-9 1984 Inhibition of superprecipitation by diltiazem was apparent at a concentration of 10(-6) M, was manifest by a rightward shift in the pCa relationship and could be attenuated by exogenous calmodulin. Diltiazem 36-45 calmodulin 1 Homo sapiens 186-196 6875846-4 1983 The relaxations produced by these calmodulin antagonists and prenylamine could not be overcome by contractile agonists which release Ca++ from internal stores (histamine and serotonin), whereas the relaxations produced by felodipine, verapamil and diltiazem were readily reversed by either of these agonists. Diltiazem 248-257 calmodulin 1 Homo sapiens 34-44 6307716-1 1983 The effect of three calcium antagonists (verapamil, nifedipine and diltiazem) on the calcium-induced activation of phosphodiesterase (a calmodulin dependent process) was investigated. Diltiazem 67-76 calmodulin 1 Homo sapiens 136-146 6307716-3 1983 In the presence of calmodulin, phosphodiesterase activity was stimulated by calcium in the range 4 X 10(-6)-2.5 X 10(-5) M. Diltiazem (10(-6) M), verapamil (10(-6) M) and nifedipine (10(-7) and 10(-6) M) had no influence on phosphodiesterase activity in the presence or absence of calmodulin at any concentration of calcium employed. Diltiazem 124-133 calmodulin 1 Homo sapiens 19-29
