Does orlistat cause acute kidney injury? Michael M To understand the mechanisms of TE action and for designing better FASN inhibitors, I examined the mechanism of orlistat hydrolysis by TE using molecular dynamics simulations. I found that the hexyl tail of orlistat undergoes a conformational transition, destabilizing a hydrogen bond that forms between orlistat and the active site histidine. A water molecule can then hydrogen bond with

Mechanism of action Figure 1: During fat digestion , lipases in the gastrointestinal tract hydrolyse fat ( triglycerides ) into smaller molecules ( free fatty acids and monoglycerides ) which can be absorbed through the duodenal mucosa., In conclusion, more research is needed to understand the effect of orlistat on fat accumulation in the colon and to find the other mechanisms of action of orlistat on cells and finally to ensure the safety of orlistat for human treatment plans..
Mechanism of action of orlistat: European medicines agency (2010) Reported orlistat is a reversible inhibitor of lipases. It exerts its therapeutic activity in the lumen of the stomach and Orlistat (Xenical: Figure 7) has a unique mechanism of action among agents approved for the treatment of obesity and was approved in the US in 1999 and in the European Union in 2003. Most dietary fat is in the form of triglycerides, i.e., three fatty acids covalently bound to a glycerol backbone. To be absorbed into the body the triglycerides are broken down into monoglycerides and free fatty
Orlistat, a gastrointestinal lipase inhibitor, reduces weight by around 3 kg on average and decreases progression to diabetes in high-risk patients; adverse gastrointestinal effects are common.
