Alogliptin benzoate Chemische Eigenschaften,Einsatz,Produktion Methoden

Verwenden
Alogliptin Benzoate is an oral antihyperglycemic agent that is a selective inhibitor of the enzyme dipeptidyl peptidase-4 (DPP-4). Alogliptin Benzoate is used in the treatment of type 2 diabetes.
Definition
ChEBI: A benzoate salt obtained by combining equimolar amounts of alogliptin and benzoic acid. Used for treatment of type 2 diabetes.
Biologische Aktivität
alogliptin is a novel, highly selective and potent inhibitor of serine protease dipeptidylpeptidase-4 (dpp-4) with ic50 value of less than 10 nm [1].alogliptin has been reported to significantly reduce plasma dpp-4 activity and increase active glp-1 levels in a dose-dependent manner in ob/ob mice. besides, alogliptin after 4 weeks administration remarkably reduced non-fasting glycosylated hemoglobin, non-fasting plasma glucose and triglyceride levels, as well as siginificantly increased non-fasting plasma insulin and fasting pancreatic insulin content in ob/ob mice. moreover, alogliptin treated ob/ob mice have shown the increase of early-phase insulin secretion and the decrease of plasma glucose auc [2]
Clinical Use
Alogliptin benzoate is a dipeptidyl peptidase IV (DPPIV) inhibitor discovered by Takeda Pharmaceuticals and approved in Japan in 2010 for the treatment of type II diabetes mellitus. Alogliptin is an oral drug for once a day dosing to complement diet and exercise. Alogliptin is the most selective marketed DPPIV inhibition and has similar PK and PD properties compared to previous entries. The discovery, structure-activity relationship of related analogs, and synthesis of this compound have been recently published.
Synthese
The most convenient synthesis for scale-up will be highlighted from several published routes. Commercially available 2-cycanobenzyl amine 1 was reacted with methylisocyanate in DCM at ambient temperature to provide N-methyl urea 2 in 85% yield. Reaction of the urea 2 with dimethyl malonate in refluxing ethanol with sodium ethoxide as base gave the cyclized trione 3 in 78-85% yield. The trione 3 was then refluxed in neat POCl3 to provide the penultimate chloride crude 4 in 95% yield which was reacted with Boc-protected diamine 5 in the presense of potassium carbonate in DMF to furnish alogliptin I in 93-96% yield. Treatment of alogliptin with benzoic acid in ethanol at 60-70 ??C followed by crystallization delivered the desired alogliptin benzoate (I).
