Triethylsilane 617-86-7 MFCD00009018

Triethylsilane is a silane with the molecular formula C6H16Si. It is a trialkylsilicon hydride compound with a reactive Si-H bond. This colorless liquid is often used in organic synthesis, specifically for the hydrosilation of olefins to give alkyl silanes. It can also be used as a reducing agent since it has an active hydride.

SynthesisTriethylsilane can be prepared by the reaction between three equivalents of ethylene and silane. This can be thought to occur by the coordination of ethylene to silicon followed by the nucleophilic olefin capturing the H in one of the Si-H bonds.

Sitagliptin
486460-32-6
Sitagliptin(INN; previously identified as MK-0431 and sold under the trade name Januvia) is an oral antihyperglycemic (anti-diabetic drug) of the dipeptidyl peptidase-4 (DPP-4) inhibitor class. It was developed and is marketed by Merck & Co. This enzyme-inhibiting drug is used either alone or in combination with other oral antihyperglycemic agents (such as metformin or a thiazolidinedione) for treatment of diabetes mellitus type 2.The benefit of this medicine is its lower side-effects (e.g., less hypoglycemia, less weight gain) in the control of blood glucose values. Exenatide (Byetta) also works by its effect on the incretin system.

Orlistat 96829-58-2 MFCD05662360 Orlistat  (marketed as a prescription under the trade name Xenical by Roche in most countries, or over-the-counter as Alli by GlaxoSmithKline in the United Kingdom and the United States), also known as tetrahydrolipstatin, is a drug designed to treat obesity.Its primary function is preventing the absorption of fats from the human diet, thereby reducing caloric intake. It is intended for use in conjunction with a physician-supervised reduced-calorie diet. Orlistat is the saturated derivative of lipstatin, a potent natural inhibitor of pancreatic lipases isolated from the bacterium Streptomyces toxytricini.However, due to simplicity and stability, orlistat rather than lipstatin was developed into an anti-obesity drug.
