Biological Activity

In cellular models, S 38093 was able to antagonize mice H3 receptors (KB=0.65µM) and to suppress cAMP decrease induced by an H3 agonist via human H3 receptors (KB=0.11µM). 

In vivo, S 38093 (0.3 and 3 mg/kg/d p.o., 28 days) significantly increases proliferation of progenitors in the DG of hippocampus in young adult mice. In mice, S 38093 significantly increases ex vivo N-tele-Methylhistamine cerebral levels from 3 mg/kg p.o. and antagonized R-α-Methylhistamine-induced dipsogenia from 10 mg/kg i.p..

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
