Z-Lys(Z)-OPcp, also known as N-benzyloxycarbonyl-L-lysine(N-benzyloxycarbonyl)-2-phenyl-2-oxopropanamide, is a synthetic peptide derivative that serves as a potent inhibitor of serine proteases, particularly chymotrypsin and trypsin. It is characterized by the presence of a benzyloxycarbonyl (Z) protecting group on the lysine side chain and an oxopropanamide moiety, which contributes to its inhibitory activity. Z-Lys(Z)-OPcp is widely used in biochemical research to study the function and regulation of serine proteases, as well as in the development of therapeutic agents targeting these enzymes. Its chemical structure and properties make it a valuable tool for understanding enzyme kinetics, substrate specificity, and the design of selective inhibitors.
The CAS Registry Mumber 13673-52-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,7 and 3 respectively; the second part has 2 digits, 5 and 2 respectively. Calculate Digit Verification of CAS Registry Number 13673-52: (7*1)+(6*3)+(5*6)+(4*7)+(3*3)+(2*5)+(1*2)=104 104 % 10 = 4 So 13673-52-4 is a valid CAS Registry Number.
