Biological Activity
CL 218872 (5-20 mg/kg; p.o.) reduces locomotor activity, head-dipping, and rearing in rats, with sedative effects reversed by Flumazenil (HY-B0009)[3].
CL 218872 (20-40 mg/kg; s.c.) antagonizes Diazepam-induced loss of righting reflex in mice[4].
CL 218872 (5-20 mg/kg; i.p.) impairs place learning in rats, increasing swim path length and reducing quadrant bias in probe trials[5].
