875932-90-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 875932-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,5,9,3 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 875932-90:
(8*8)+(7*7)+(6*5)+(5*9)+(4*3)+(3*2)+(2*9)+(1*0)=224
224 % 10 = 4
So 875932-90-4 is a valid CAS Registry Number.

New substrates and inhibitors of γ-aminobutyric acid aminotransferase containing bioisosteres of the carboxylic acid group: Design, synthesis, and biological activity

Yuan, Hai,Silverman, Richard B.

, p. 1331 - 1338 (2006)

A series of potential substrates of γ-aminobutyric acid aminotransferase (GABA-AT) with lipophilic bioisosteres of the carboxylic acid group (2-7) were synthesized and tested. Most of the synthesized compounds showed substrate activities with GABA-AT; 1H-tetrazole-5-propanamine (6) was the best of those tested. The potential time-dependent inhibitor of GABA-AT, 1H-tetrazole-5-(α-vinyl-propanamine) (8), was designed based on the structures of 6 and the antiepilepsy drug vigabatrin (4-aminohex-5-enoic acid, 1). The synthesized compound 8 showed time-dependent inhibition of GABA-AT, but its potency is lower than that of vigabatrin. Methylation of the tetrazole group in 8 resulted in loss of time-dependent activity, suggesting that the tetrazole ring, the carboxylate bioisostere, exists in its deprotonated form in the enzyme active site.
