Biological Activity
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].

Protocol
Rats: In order to find out the proper pre treatment time with HSR-6071, 0.03 mg/kg, i.vi or 1 mg/kg, p.o. of HSR-6071 was given at varying times before the antigen challenge[2].
