(Z-L-Cys-L-PheOMe)2 is a synthetic cyclic dipeptide consisting of two identical units of Z-L-Cys-L-PheOMe linked together. The molecule features a Z-protecting group on the cysteine (Cys) residue, which is a common strategy in peptide synthesis to prevent unwanted side reactions. The cysteine is in its L-configuration, which is the naturally occurring form in proteins. Phenylalanine (Phe) is also in the L-configuration and is methylated at the hydroxyl group (OMe), which can influence the peptide's solubility and reactivity. This specific dipeptide is of interest in chemical and pharmaceutical research due to its potential applications in drug design and as a model for understanding peptide structure and function. The cyclic nature of (Z-L-Cys-L-PheOMe)2 can lead to unique biological activities and interactions with biological targets, making it a valuable compound for exploration in various scientific fields.

Check Digit Verification of cas no

The CAS Registry Mumber 3693-93-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,9 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3693-93:
(6*3)+(5*6)+(4*9)+(3*3)+(2*9)+(1*3)=114
114 % 10 = 4
So 3693-93-4 is a valid CAS Registry Number.

Cysteinyl peptide inhibitors of Bacillus cereus zinc β-lactamase

Bounaga, Sakina,Galleni, Moreno,Laws, Andrew P,Page, Michael I

, p. 503 - 510 (2007/10/03)

Several cysteinyl peptides have been synthesised and shown to be reversible competitive inhibitors of the Bacillus cereus metallo-β-lactamase. The pH dependence of pKi indicates that the thiol anion displaces hydroxide ion from the active site zinc(II). D,D-Peptides bind to the enzyme better than other diastereoisomers, which is compatible with the predicted stereochemistry of the active site.
