产品介绍
(±)-Tazifylline 是一种选择性的长效组胺 H1 受体拮抗剂。 Tazifylline 对 H2 受体、α- 和 β-肾上腺素能受体、5-羟色胺和毒蕈碱受体亚型的亲和力要低得多。

产品描述

(±)-Tazifylline is a selective and long-acting antagonist of histamine H1 receptor. Tazifylline shows much lower affinity for H2 receptors, α- and β-adrenoceptors, 5-hydroxytryptamine and muscarinic receptor subtypes.

体外活性

Tazifylline potently inhibits contractions evoked by stimulation of histamine H1-receptors in isolated guinea pig ilea and exhibits high affinity in radioligand binding studies[1].

体内活性

In anesthetized guinea pigs, Tazifylline causes an inhibition in histamine-induced bronchoconstriction and protects conscious animals from the lethal effect of large doses of the amine. In conscious rats, Tazifylline reduces the inflammatory effects of intradermal histamine. In conscious dogs, Tazifylline(orally) causes inhibition in histamine-induced skin inflammation for long periods of time, and in anesthetized animals attenuated that portion of the histamine-evoked hypotension attributable to stimulation of H1 receptors. Large oral doses of Tazifylline do not reduce spontaneous locomotor activity in mice, nor do they produce overt symptoms of behavioral depression in conscious rats[1].
