In vivo | A-77636 (0-3.2 μmol/kg, subcutaneous injection) induced rotational behavior in rats with 6-OHDA lesions (ED50 = 0.32 μmol/kg sc) [1]. The compound A-77636 (1-10 mg/kg) attenuated drug-induced locomotor activity in a dose-dependent manner [2]. A-77636 elicited forelimb clonus in rats (ED50 = 12.3 μmol/kg s.c.) and mice (ED50 = 12.1 μmol/kg s.c.) [1]. In marmosets treated with MPTP to induce a Parkinsonian state, A-77636 (0.5, 1.0, or 2.0 μmol/kg, oral administration) increased motor activity and reduced the severity of Parkinsonian symptoms, with the compound demonstrating activity following both subcutaneous and oral administration [1]. |
