57089-24-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57089-24-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,0,8 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 57089-24:
(7*5)+(6*7)+(5*0)+(4*8)+(3*9)+(2*2)+(1*4)=144
144 % 10 = 4
So 57089-24-4 is a valid CAS Registry Number.

Synthesis of substrate analogues as potential inhibitors for Mycobacterium tuberculosis enzyme MshC

Patel, Krishnakant,Song, Fengling,Andreana, Peter R.

, p. 10 - 18 (2017/11/07)

Mycothiol cysteine ligase (MshC) is a key enzyme in the mycothiol (MSH) biosynthesis and a promising target for developing new anti-mycobacterial compounds. Herein, we report on the synthesis of substrate analogues, as potential inhibitors, for the MshC e

Synthesis of high-performance polyurethanes with rigid 5-6-5-fused ring system in the main chain from naturally occurring myo-inositol

Sudo, Atsushi,Shibata, Yoshiya,Miyamoto, Ayano

, p. 3956 - 3963 (2013/09/02)

A bisketal of myo-inositol was used as a diol-type monomer for synthesis of polyurethanes. The monomer was obtained by treatment of myo-inositol with 1,1-dimethoxycyclohexane in the presence of p-toluenesulfonic acid as a catalyst. The ketalization resulted in the formation of a 5-6-5-fused ring system, which endowed the diol-type monomer with high rigidity. The diol readily reacted with diisocyanate to give the corresponding polyurethane, which exhibited excellent heat resistance due to the rigid 5-6-5 system in the main chain. Copyright

First Total Synthesis of Mycothiol and Mycothiol Disulfide

Lee, Sungwon,Rosazza, John P. N.

, p. 365 - 368 (2007/10/03)

(Matrix presented) The first total synthesis of mycothiol and mycothiol disulfide was achieved by linking D-2,3,4,5,6-penta-O-acetyl-myo-inositol, O-(3,4,6-tri-O-acetyl)-2-azido-2-deoxy-α,β-D-glucopyranosyl) trichloroacetimidate, and N,S-diacetyl-L-cysteine and deprotecting peracetylated mycothiol. The first full spectral characterization is reported for underivatized mycothiol. The structure of mycothiol was confirmed by spectral analysis of the known bimane derivative.
