常見問題列表

生物活性
Bamirastine 抑制配體結(jié)合到重組人組胺 H1 受體 (rhH1R),IC50 為 17.3 nM。
靶點

IC50: 17.3 nM (rhH 1 R)

體外研究

Bamirastine (TAK-427) reduces specific binding of [ 3 H] pyrilamine to recombinant human H 1 receptors (rhH 1 R) is seen in a concentration- dependent manner with an IC 50 value of 17.3 nM. The K i value is calculated to be 7.35 nM. The affinity of Bamirastine is found to be as high as that of azelastine, 2 times lower than that of Epinastine, 8 times lower than that of ketotifen and 3 times higher than that of Terfenadine.

體內(nèi)研究

Bamirastine (TAK-427) inhibits histamine induced skin reactions in guinea pigs and mice with an ID 50 value of 0.884 and 0.450 mg/kg, p.o., respectively; significant inhibition associated with 10 mg/kg of Bamirastine is still observed 24 h after dosing in guinea pigs. Even at 300 mg/kg, Bamirastine does not affect pentobarbital-induced sleeping time in mice. Bamirastine significantly inhibits passive cutaneous anaphylaxis (PCA) in mice and guinea pigs, and also inhibits antigen-induced ISRs in guinea pigs.
