Biological Activity

Description

(±)-Tazifylline is a potent, selective and long-acting histamine H1 receptor antagonist.

IC₅₀ & Target

H1-receptor^[1]

All Histamine Receptor Isoforms :

In Vitro

Tazifylline potently inhibits contractions evoked by stimulation of histamine H1-receptors in isolated guinea pig ilea and exhibits high affinity for these receptors in radioligand binding studies in vitro Tazifylline has much lower affinity for histamine H2-receptors, alpha- and beta-adrenoceptors, 5-hydroxytryptamine and muscarinic receptor subtypes. Tazifylline poorly inhibits the release of histamine from rat peritoneal mast cells^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

In rats, guinea pigs and dogs the antihistaminic effect of Tazifylline is rapid in onset and long-lived. In anesthetized guinea pigs, Tazifylline markedly inhibits histamine-induced bronchoconstriction and protects conscious animals from the lethal effect of large doses of the amine. In conscious rats, Tazifylline is more potent in reducing the inflammatory effects of intradermal histamine than that evoked by anaphylactic reaction. In conscious dogs, orally administered Tazifylline inhibits 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 does not reduce spontaneous locomotor activity in mice, nor do they produce overt symptoms of behavioral depression in conscious rats^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
