 | Hazard Information | Back Directory |  | [Uses] 
 NAD 299 Hydrochloride is a selective, high affinity 5-HT1A antagonist, used in psychotropic drug development.
 |  | [Biological Activity] 
 Selective, high affinity 5-HT 1A receptor antagonist (K i = 0.6 nM in vitro ).

 Robalzotan  (1-100 μg/kg; i.v.) significantly increases the activity of such neurons at 5 μg/kg in rats, and reverses the acute inhibitory effect of citalopram (HY-121203) (300 μg/kg i.v.) or paroxetine (HY-122272) (100 μg/kg, i.v.) on the activity of 5-HT neurons in the dorsal raphe nucleus in rats[1].Robalzotan (5, 50 μg/kg; i.v.) increases the firing rate of the 5-HT cells[1].
 Robalzotan (2-100 μg/kg; i.v.) occupies 5-HT1A receptors in a dose-dependent in monkeys[2].
 Robalzotan (0.3; 1 and 3 μmol/kg s.c) causes a dose-dependent increase of extracellular ACh levels in the rat FC[3].
