The pharmacokinetics of the injectable dosage form of GK-2 in rabbits

Abstract

The pharmacokinetics of the nerve growth factor mimetic GK-2 (dimeric dipeptide mimetic of the 4-th loop NGF, a derivative of fluoro-substituted 5-[2-(5-fluoropyrid-3-yl) -ethyl)]-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole) in rabbits after a single intravenous injection of an injectable dosage form at dose 24 mg (7,8-8,7 mg/kg). GK-2 concentrations in the blood plasma were determined by high-performance liquid chromatography with massspectrometric detection. GK-2 can be attributed to "short-lived" drugs, since the half-life from the rabbits blood plasma was 0.9±0.1 h.
