用途: Clemastine Fumarate is a selective histamine H1 receptor antagonist with IC50 of 3 nM.Target: Histamine H1 ReceptorClemastine Fumarate inhibits histamine induced rise in [Ca2+]i in HL-60 cells with an IC50 of 3 nM as compared with that of chlorpheniramine or diphenhydramine with IC50 values of 20 nM and 100 nM, respectively [1]. Clemastine showed a first-pass reduction in the extent of absorption, with oral bioavailability calculated as 39.2 +/- 12.4%. Extravascular distribution of drug was suggested by the high volume of distribution (799 +/- 315 L) and low Cmax (0.577 +/- 0.252 ng/mL/mg) observed at 4.77 +/- 2.26 hours after administration, and by the biphasic decline in plasma concentration. The terminal elimination half-life (t1/2) of clemastine was 21.3 +/- 11.6 hours. Steady-state concentrations of clemastine were consistent with linear pharmacokinetic processes, and clearance was unaffected by age in the range studied, or by race [2]. 物理化学性质: CAS号:14976-57-9 常用中文名:富马酸氯马斯汀 常用英文名:Clemastine fumarate 分子式:C25H30ClNO5 分子量:459.962 密度:1.097 g/cm3 沸点:116 °C / 24mmHg 熔点:61 °C 闪点:211ºC 储存条件:Store at RT |
