Description

HSR6071, a pyrazinecarboxamide derivative, is an orally active and potent antiallergic agent. HSR6071 potently inhibits the experimental asthma in rat models[1][2].

In Vivo

The experimental asthma caused by IgE antibody in rats is inhibited by HSR-6071 (0.01-0.1 mg/kg; i.v.) in a dose-dependent manner. The bronchoconstriction mediated by IgE or IgG antibody in guinea-pigs is also prevented by HSR-6071 (0.3, 1,3 mg/kg; i.v.). HSR-6071 inhibits cyclic AMP phosphodiesterase activity and produces relaxation of the guinea-pig isolated trachea[1].
HSR-6071 inhibits the IgE-mediated histamine release with an IC50 of 0.46 nM. HSR-6071 is effective not only by i.v. but also by p.o. administration on the IgE mediated PCA in rats. The most potent inhibition with HSR-6071 is observed when it is given p.o. 5 min before the antigen challenge, indicating the rapid absorption of HSR-6071 through the gastrointestinal tract[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
