2. An inhibitor of aromatic amino acid decarboxylase.

Check Digit Verification of cas no

The CAS Registry Mumber 302-53-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,0 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 302-53:
(5*3)+(4*0)+(3*2)+(2*5)+(1*3)=34
34 % 10 = 4
So 302-53-4 is a valid CAS Registry Number.

Chiral lithium binaphtholate for enantioselective amination of acyclic α-alkyl-β-keto esters: Application to the total synthesis of L-carbidopa

Asano, Toshifumi,Moritani, Miyuki,Nakajima, Makoto,Kotani, Shunsuke

, p. 5975 - 5982 (2017/09/18)

A chiral lithium binaphtholate catalyzes the enantioselective amination of α-alkyl-β-keto esters with azodicarboxylates to produce optically active α,α-disubstituted α-amino acid derivatives in high yields and with good to high enantioselectivities. A stoichiometric amount of lithium hydroxide efficaciously improved both the reactivity and enantioselectivity of amination. The resulting aminated product is readily convertible to L-carbidopa.

Synthesis of dendrimer-type chiral stationary phases based on the selector of (1S,2R)-(+)-2-amino-1,2-diphenylethanol derivate and their enantioseparation evaluation by HPLC

He, Bao-Jiang,Yin, Chuan-Qi,Li, Shi-Rong,Bai, Zheng-Wu

experimental part, p. 69 - 76 (2010/09/09)

In our recent work, a series of dendritic chiral stationary phases (CSPs) were synthesized, in which the chiral selector was L-2-(p-toluenesulfonamido)-3- phenylpropionyl chloride (selector I), and the CSP derived from three-generation dendrimer showed the best separation ability. To further investigate the influence of the structures of dendrimer and chiral selector on enantioseparation ability, in this work, another series CSPs (CSPs 1-4) were prepared by immobilizing (1S,2R)-1,2-diphenyl-2-(3-phenylureido)ethyl 4-isocyanatophenylcarbamate (selector II) on one- to four-generation dendrimers that were prepared in previous work. CSPs 1 and 4 demonstrated the equivalent enantioseparation ability. CSPs 2 and 3 showed the best and poorest enantioseparation ability respectively. Basically, these two series of CSPs exhibited the equivalent enantioseparation ability although the chiral selectors were different. Considering the enantioseparation ability of the CSP derived from aminated silica gel and selector II is much better than that of the one derived from aminated silica gel and selector I, it is believed that the dendrimer conformation essentially impacts enantioseparation.

Kinetic study of the reaction of pyridoxal 5'-phosphate with hydrazino compounds of pharmacological activity

Echevarria-Gorostidi,Basagoitia,Pizarro,Goldsmid,Blanco,Blanco

, p. 837 - 844 (2007/10/03)

The kinetics of the reaction between pyridoxal 5'-phosphate (PLP) with carbidopa, hydralazine, and isoniazid, in aqueous solution at variable pH and constant ionic strength of 0.1M was studied spectrophotometrically. The rate constants of formation and hydrolysis of the resulting Schiff base, and its stability were determined in a wide range of pH. A comparison is made of the formation rate constants with those of PLP with hydrazine. The reactivity shows the sequence isoniazid > hydrazine > carbidopa > hydralazine in the whole range of pH studied. The Schiff bases studied are more stable than those formed by PLP and hexylamine and as stable as those described for the reactions of PLP with poly(L-lysine) or copolypeptides containing L-lysine.
