4-Methylhistamine
4-Methylhistamine is a potent and selective agonist of histamine 4 receptor (H4R) with a Ki of 50 nM. 4-Methylhistamine has a >100-fold selectivity for the hH4R over the other histamine receptor subtypes. 4-Methylhistamine can potently activate the hH4R (pEC50 = 7.4). 4-Methylhistamine can be used for the researches of cancer, inflammation and immunology, such as lung cancer and skin inflammation.
