Verwenden
A 987306 is an H4 receptor antagonist and has been studied as an H4 modulator towards the potential treatment of diseases.
Biologische Aktivität
a987306,cis-4-(piperazin-1-yl)-5,6,7a,8,9,10,11,11a-octahydrobenzofuro[2,3-h]quin- azolin-2-amine[1], is a selective and potent h4 receptor antagonist [2].h4r is one of 4 known g-protein-coupled receptors (h1, h2, h3 and h4 receptors) of histamine. it is for mediating some physiological functions of histamine [3].in a cell-based ca2+-flux functional assay, a 987306 had no activation to the receptor, but blocked the h4r activation induced by endogenous histamine. a 987306 potently decreased histamine-mediated binding between rat h4-receptor-containing membranes and gtp-γ-[35s] with a kb of 6 nm [3].in sprague-dawley rats, after ip injection, a 987306 had a favorable fractional bioavailability (fip/iv =72%), a half-life of 4.7 h and a cmax of 1.73 μm at a tmax of 0.25 h after dosing. after oral dosing, a 987306 had a moderate fractional oral bioavailability (fpo/iv =26%) with a half-life of 3.7 h and a cmax of 0.30 μm at a tmax of 1.5 h after dosing. the plasma protein binding of a 987306 measured in rats was found to be 59% [3].to human h4r and rat h4r, the ki values of a 987306 are 5.8 nm and 3.4 nm, respectively. a 987306 reduced scratch responses in mice with an ed50 of 0.36 μmol/kg. a 987306 was found to be selective and bear an ic50 > 810 nm for over 100 kinases [3].
