4-Methylhistamine dihydrochloride Usage And Synthesis

Description

4-Methylhistamine (dihydrochloride) is the potent agonist of histamine 4 receptor (H4R). 4-Methylhistamine (dihydrochloride) has the potential for the research of immune-related diseases such as cancer and autoimmune disorders.

Uses

Histamine H2 receptor agonist, antagonist and antineoplastic agent on the in vitro growth of peripheral blood CFU-GM from normal individuals and HL-60 leukemia cells.

Biological Activity

4-Methylhistamine dihydrochloride is a potent, high affinity H4 receptor agonist (Ki = 7 nM) that displays > 100-fold selectivity over other human histamine receptor subtypes.

storage

Desiccate at RT
