Indications and Usage

Alogliptin (benzoic acid) is a type-2 diabetes medication, and it is a type of serine protease dipeptidyl peptidase IV (DPP-4) inhibitor developed by the Japanese company Takeda. Alogliptin, used alone or in combination with other blood sugar-lowering medication, is usually well-tolerated in type-2 diabetes patients. This medication has a low risk of hypoglycemia, with Alogliptin treatment groups ≤8.3% and placebo groups ≤10.5%, and shows no difference between young and elderly patients. In addition to effectively lowering blood sugar, this medicine also lowers the risks of hypoglycemia and weight increase, overcoming great obstacles in patient treatment and providing new hope for diabetes treatment.

Mechanisms of Action

Alogliptin selectively inhibits DPP-4 to reduce the inactivation of glucagon-like peptide 1 (GLP-1) and increase the GLP-1 levels in the body, thus lowering blood sugar. Once blood sugar reaches normal levels, it will cease its sugar-lowering effects, thus effectively reducing the risks of hypoglycemia. Additionally, DPP-4 inhibitor also slows gastric emptying, increases the feeling of fullness, and controls appetite, thus helping patients control their weight.

Adverse reactions

Common side effects of Alogliptin include nasopharyngitis, headaches, and upper respiratory tract infection. Most side effects are light to moderate and are unrelated to dosage.

Uses

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.

Biological Activity

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.

Synthesis

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).

Check Digit Verification of cas no

The CAS Registry Mumber 850649-62-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,6,4 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 850649-62:
(8*8)+(7*5)+(6*0)+(5*6)+(4*4)+(3*9)+(2*6)+(1*2)=186
186 % 10 = 6
So 850649-62-6 is a valid CAS Registry Number.

Development and Scale-Up of an Asymmetric Synthesis Process for Alogliptin

Yamada, Masatoshi,Hirano, Sayuri,Tsuruoka, Ryoji,Takasuga, Masahiro,Uno, Kenichi,Yamaguchi, Kotaro,Yamano, Mitsuhisa

, p. 327 - 336 (2021/03/01)

Alogliptin (1) benzoate is a potent, highly selective inhibitor of serine protease dipeptidyl-peptidase IV, approved by US FDA for the treatment of type 2 diabetes. Herein, we report a more cost-effective process that includes ruthenium-catalyzed asymmetric hydrogenation followed by Hofmann rearrangement of 2-((6-chloro-3-methyl-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)methyl)benzonitrile (10) to introduce a chiral amino moiety at a late stage. Use of an inexpensive and readily available nicotinamide (6) for a chiral aminopiperidine core and iodobenzene diacetate (PIDA) under mild and specific conditions allowed us to access 1 with excellent total yield and comparable quality to that manufactured by the original process.
