Lipase Inhibitor, THL (Tetrahydrolipstatin), is a compound that has been shown to rapidly inactivate lipoprotein lipase (LPL). This agent has been found to bind both subunits of LPL, induce tetramerisation, and cause local conformational changes. The exception to lipase inhibition capacities of THL is phospholipase A2, which is not affected by THL. Mechanistic studies sμggest that THL inhibits the thioesterase domain of fatty acid synthase (FAS) and as a result halts cell proliferation and causes cell apoptosis. More detailed experiments show that gradually THL affects the retinoblastoma protein pathway and leads to cell-cycle arrest at G1/S boundary. Lipase Inhibitor, THL is an inhibitor of pancreatic and gastric lipase, as well as carboxyl ester lipase (CEL) and diacylglycerol lipase-α (DAGLα). Lipase Inhibitor, THL also activates caspase-3.Orlistat是一种通用的脂肪酶抑制剂,作用于人体十二指肠液的PL,IC50为122 ng/ml。
Information
Orlistat (Ro 18-0647) Orlistat (Ro 18-0647, Tetrahydrolipstatin) is a general lipase inhibitor with IC50 of 122 ng/ml for PL from human duodenal juice. Orlistat treatment reduces proliferation, induces apoptosis and arrests cell cycle.
In vitro
Orlistat, an inhibitor of lipases and fatty acid synthase, is used orally for long-term treatment of obesity. Orlistat shows antiproliferative activity against cancer cells in vitro. It has been found to augment pro-apoptotic NOXA protein.
In vivo
Orlistat, administered by oral route, is minimally absorbed by the gastrointestinal tract and is able to prevent the absorption of a large percentage of lipids, thereby reducing lipid supply from outside sources. Because of its extremely low oral bioavailability, the effects of Orlistat are largely confined to the gastrointestinal tract, where it inactivates pancreatic lipase. Therefore, the formulation and route of delivery would have to be changed to treat tumors of the breast, prostate, and so on. Orlistat halts tumor cell proliferation, induces tumor cell apoptosis, and inhibits the growth of PC-3 tumors in nude mice. A pharmacokinetic analysis of Orlistat (155 mg/kg) administered by i.p. injection showed peak blood levels to be ∼10 μM 2 h after dosing (data not shown). Beyond this time, blood levels of the drug decayed rapidly.
