6401-63-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6401-63-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6401-63:
(6*6)+(5*4)+(4*0)+(3*1)+(2*6)+(1*3)=74
74 % 10 = 4
So 6401-63-4 is a valid CAS Registry Number.

Application of proteasome inhibitor in inhibition of novel coronavirus

-

, (2021/06/22)

The invention provides application of a proteasome inhibitor in inhibition of a novel coronavirus or preparation of novel coronavirus inhibitors. The proteasome inhibitor has a structure represented by a formula (I) or isomers, pharmaceutically acceptable salts thereof and prodrugs thereof. According to the application, by applying the proteasome inhibitor to inhibition of the novel coronavirus, good inhibiting activity is obtained, and a novel treatment way of think is provided for diseases such as pneumonia caused by the novel coronavirus.

Convenient green preparation of dipeptides using unprotected α-amino acids

Dipeptides and amides were obtained in high yields from N-carbobenzyloxy α-amino acids and 3-phenylpropanoic acid with unprotected α-amino acids via the corresponding mixed carbonic carboxylic anhydrides using ethyl chloroformate and triethylamine by an ecological and convenient method in which the protection of C-terminals is not needed.

One-step C-terminal deprotection and activation of peptides with peptide amidase from stenotrophomonas maltophilia in neat organic solvent

Arif, Muhammad I.,Toplak, Ana,Szymanski, Wiktor,Feringa, Ben L.,Nuijens, Timo,Quaedflieg, Peter J. L. M.,Wu, Bian,Janssen, Dick B.

, p. 2197 - 2202 (2014/07/21)

Chemoenzymatic peptide synthesis is a rapidly developing technology for cost effective peptide production on a large scale. As an alternative to the traditional C→N strategy, which employs expensive N-protected building blocks in each step, we have investigated an N→C extension route that is based on activation of a peptide C-terminal amide protecting group to the corresponding methyl ester. We found that this conversion is efficiently catalysed by Stenotrophomonas maltophilia peptide amidase in neat organic media. The system excludes the possibility of internal peptide cleavage as the enzyme lacks intrinsic protease activity. The produced peptide methyl ester was used for peptide chain extension in a kinetically controlled reaction by a thermostable protease.
