APD668是有效的GPR119激动剂，对人源GPR119和大鼠GPR119的EC50值分别为2.7 nM和33 nM。 Information APD668 APD668 (JNJ28630368) is a potent GPR119 agonist with EC50s of 2.7 and 33 nM for human and rat forms, respectively. Targets human GPR119 ; rat GPR119 2.7 nM(EC50); 33 nM(EC50) In vitro APD668 is shown to increase adenylate cyclase activation in HEK293 cells transfected with human GPR119 (but not in non-transfected cells) in a concentration-dependent manner with an EC50 of 23 nM. APD668 also enhanced insulin release from both rat and human isolated pancreatic islets in a glucose-dependent manner. In a standard panel of around 80 known receptors and ion channels, APD668 did not show any binding in excess of 50% of control to any other proteins at concentrations up to 10 μM. In vivo Chronic treatment with APD668 showed that blood glucose and glycated hemoglobin (HbA1c) levels could be significantly reduced in Zucker Diabetic Fatty (ZDF) rats over several weeks of dosing. APD668 is highly bound to plasma proteins of male and female cynomolgus monkeys and humans (P99%), but was less extensively bound to male (93.0%) and female (96.6%) rats. In pharmacokinetic assessments across multiple species using single oral doses of APD668, absorption was rapid to moderate (Tmax 62 h) in mice, Sprague-Dawley (SD) rats, and monkeys, but slower in dogs (Tmax = 6 h) and showed a dose-dependent increase in rats and monkeys. In general, exposure was dose-dependent at lower doses and appeared to plateau at doses greater than 300 mg/kg. Exposure was greater in female rats compared with males. Absolute oral bioavailability was moderate to good in mice, rats, and monkeys (44–79%), but was lower in dogs (22%). The volume of distribution (Vdss) values were somewhat variable ranging from 0.1 L/kg in monkey to 2.6 L/kg in rats. Elimination, based on mean T1/2 after intravenous (iv) dosing, was rapid to moderate in mice, rats, dogs, and monkeys (0.8-3.9 h). The pharmacokinetic profile of APD668 in Zucker fa/fa rats was somewhat different from that in SD rats. After oral administration, the tmax and T1/2 were longer, and the AUC and the oral bioavailability were greater in the Zucker compared with the SD rats. Following iv administration, the Zucker rats also had larger AUC values, longer T1/2 values and greater Vdss values.
