Orlistat-d3

Orlistat-d3 is intended for use as an internal standard for the quantification of orlistat (Cay-10005426) by GC- or LC-MS. Orlistat is a digestive lipase inhibitor. It inhibits diacylglycerol lipase alpha (DAGLalpha), DAGLbeta, alpha/beta-hydrolase domain-containing protein 12 (ABHD12), ABHD16A, and platelet-activating factor acetylhydrolase (PAF-AH, IC50s = 0.06, 0.1, 0.08, 0.03, and 0.05 µM, respectively), as well as pancreatic lipase and hormone-sensitive lipase (IC50s = 0.65 and 2.1 µg/ml, respectively) but does not inhibit fatty acid amide hydrolase (FAAH) or KIAA1363 (IC50s = >100 µM for both). Orlistat decreases ionomycin-induced production of the endocannabinoid 2-arachidonoyl glycerol (2-AG) in N18TG2 murine neuroblastoma cells when used at a concentration of 1 µM. It also inhibits fatty acid synthase (FASN, Ki = ~0.1 µM for the human enzyme) and the proliferation of PC3 prostate cancer cells in a concentration-dependent manner. Orlistat (10 mg/kg) decreases serum cholesterol levels and total body weight in a mouse model of obesity induced by a high-fat diet. Formulations containing orlistat have been used in the treatment of adult obesity.Formal Name: N-formyl-L-leucine-5,5,5-d3, (1S)-1-[[(2S,3S)-3-hexyl-4-oxo-2-oxetanyl]methyl]dodecyl ester.
