in vitro study | APD668 increases adenylate cyclase activation in HEK293 cells transfected with human GPR119 in a concentration-dependent manner with an EC 50 of 23 nM. APD668 is high bound to plasma proteins of male and female cynomolgus monkeys and humans (99%), but is less extensively bound to male (93.0%) and female (96.6%) rats. |
in vivo study | APD668 (10-30 mg/kg; P.o. once daily for 8 weeks) significantly reduces blood glucose and glycated hemoglobin (HbA1c) levels, with no desensitization of the acute drug response. APD668 (1-10 mg/kg; A single p.o.) markedly reduces blood glucose levels during oral glucose tolerance test in a dose-dependent manner in mice. APD668 (0.08 mg/kg/min; I. v.) shows no effect during euglycemic condition, but significantly stimulates insulin release when blood glucose levels are raised to approximately 300 mg/dl in a hyperglycemic clamp model in the Sprague-Dawley rat. APD668 (p.o.) exhibits rapid to moderate absorption (tmax ≤ 2 h) in mice, rats, and monkeys, but slow in dogs (t max = 6 h), and moderate to good absolute oral bioavailability (44-79%) in mice, rats, and monkeys, but lower in dogs (22%). Animal Model: Male Zucker Diabetic Fatty (ZDF) Rats (6 weeks old, 200-250g) Dosage: 10, 30 mg/kg Administration: P.o. once daily for 8 weeks Result: decreased the blood glucose and HbA1c levels at 30 mg/kg/day. did not develop diabetes whereas the vehicle treated ats did. |
