This invention relates to novel compounds which are inhibitors of 
acyl coenzyme A: 
diacylglycerol acyltransferase 1 (DGAT-1), to pharmaceutical compositions containing them, to processes for their preparation, and to their use in therapy, alone or in combination with 
weight management therapies or other 
triglyceride lowering therapy for the prevention or treatment of diseases related to DGAT-1 dysfunction or where modulation of DGAT-1 activity may have therapeutic benefit including but not limited to 
obesity, 
obesity related disorders, genetic (Type 1, Type 5 
hyperlipidemia) and acquired forms of 
hypertriglyceridemia or hyperlipoproteinemia-related disorders, caused by but not limited to 
lipodystrophy, hypothyroidism, medications (beta blockers, thiazides, 
estrogen, glucocorticoids, transplant) and other factors (
pregnancy, 
alcohol intake), hyperlipoproteinemia, chylomicronemia, 
dyslipidemia, non-
alcoholic steatohepatitis, diabetes, 
insulin resistance, 
metabolic syndrome, cardiovascular outcomes, 
angina, excess 
hair growth (including syndromes associated with 
hirsutism), 
nephrotic syndrome, 
fibrosis such as myocardial, renal and 
liver fibrosis, 
hepatitis C 
virus infection and 
acne or other
