6、dose, which lowers serum triglycerides by 53%.Similarly, the 3 mg/kg dose of A 922500 significantly reduces serum FFA concentrations by 55% and totalcholesterol by 25%. DGAT-1 inhibition has no significant effect on body weight at any dose tested. AlthoughA 922500 dpes not significantly affect LDL-c

7、holesterol or HDL-cholesterol individually, the serum LDL/HDL-cholesterol ratio is significantly improved by A 922500 at 0.3 and 3 mg/kg. Similar to the dyslipidemichamster, treatment with 3 mg/kg A 922500 significantly reduces serum triglyceride concentrations (39%).FFA levels significantly increas

8、e over the 14-day period in vehicle-treated animals. This increase is inhibitedin a dose-dependent manner by A 922500 such that FFA concentrations are 32% lower after 14 days oftreatment with the DGAT-1 inhibitor at 3 mg/kg, compared with the vehicle group (p 0.05). HDL-cholesterolis significantly i

Body weight significantly increases overthe 2-week period in vehicle-treated rats, and this is not affected by A 922500. LDL-cholesterol is significan

DGAT-1 inhibition does not further reduce LDL-cholesterol and has noeffect on total cholesterol 1.PROTOCOLAnimal Mice and Hamsters 1Administration 1 Thirteen-week-old male Golden Syrian hamsters (n=40), initially weighing approximately 140 g, are used.Ten-wee

11、k-old Male Zucker fatty rats (n=32), weighing between 270 and 330 g, are used.
