Description of Orlistat

Orlistat is an irreversible inhibitor of lipases in the pancreas and stomach. It is a drug for the treatment of obesity. It suppresses the action of gastrointestinal lipases, thereby impairing the metabolism of lipids in the gastrointestinal lumen, which can prevent the absorption of 30% of the lipids in dietary fat[1,2]. Orlistat is very hydrophobic and binds covalently to the active serine residues of pancreatic lipase. Orlistat passes through cell membranes sufficiently and exerts intracellular effects[3].

Orlistat(0-25µM;32h) induced a pronounced antiproliferative effect in the PC-3 cell line[4]. Orlistat inhibits Jurkat cell growth and induces a perturbation of cell cycle along with a decline of FASN activity and protein levels[6]. Orlistat-mediated(0-50µM) FASN inhibition could overcome sorafenib resistance and enhance cell killing in HCC by changing cell metabolism[7].

Orlistat(10 mg/kg/day, p.o.) alleviates colon cancer promotion in WD-driven CAC mice by suppressing inflammation, especially by inhibiting STAT3 and NF-κB activation[5].Orlistat(240 mg/kg/day;3 weeks; i.p.) prevented the growth of PC-3 tumors. Animals exhibited no outward signs of toxicity, experienced no loss of weight, nor were there any effects of Orlistat on hematocrit or WBC levels[4].

Protocol of Orlistat

Cell experiment [1]:

Cell lines

prostate cancer cells(PC3)

Preparation Method

The effect of Orlistat on proliferation of prostate cancer cells was measured by the incorporation of bromodeoxyuridine (BrdUrd). PC-3 was seeded as subconfluent monolayers into microtiter plates. Cells were exposed to Orlistat for 32 h, then a BrdUrd labeling solution was added to the wells.

Reaction Conditions

0-25µM;32h

Applications

Orlistat induced a pronounced antiproliferative effect in the PC-3 cell line.

Animal experiment [2]:

Animal models

Male athymic nude mice 4-5 weeks of age

Preparation Method

PC-3 cells were injected into the flank of nude mice. Tumors were allowed to grow until they reached a size of 100 mm3, at which time administration of Orlistat or vehicle was initiated in separate sets of 8 mice. Orlistat was administered at 240 mg/kg/day for a period of 3 weeks.

Dosage form

240 mg/kg/day;3 weeks; i.p.

Applications

Orlistat prevented the growth of PC-3 tumors.
