Fendiline 64-73 coagulation factor II, thrombin Homo sapiens 99-107 2030746-4 1991 The effect of fendiline could be partly reversed by extracellular Ca2+ and higher thrombin concentrations. Fendiline 14-23 coagulation factor II, thrombin Homo sapiens 82-90 2030746-5 1991 Furthermore, aggregations induced by the calcium ionophore ionomycin and by the protein kinase C-activator 4-beta-phorbol 12-myristate 13-acetate were inhibited by fendiline, although to a smaller degree than the thrombin-induced aggregation. Fendiline 164-173 coagulation factor II, thrombin Homo sapiens 213-221 2030746-6 1991 Thrombin-induced secretion of ATP was attenuated by low concentrations of fendiline (1-3 microM) and calmidazolium (1 microM) but enhanced by higher concentrations (10-30 and 3-10 microM, respectively), independently of extracellular Ca2+. Fendiline 74-83 coagulation factor II, thrombin Homo sapiens 0-8
