Z-Met-O(TBA), also known as Z-Met-O-(TBA)-amide, is a chemical compound that serves as a protease inhibitor. It is a derivative of methionine, an essential amino acid, with a tert-butyl acetate (TBA) protecting group and a benzyloxycarbonyl (Z) group. The Z group is a commonly used protecting group in peptide synthesis, which prevents the amino group from reacting until it is specifically removed. The TBA group is used to protect the hydroxyl group, ensuring that the compound remains stable during synthesis. Z-Met-O(TBA) is utilized in the study of proteases, which are enzymes that break down proteins, and plays a crucial role in understanding their mechanisms and potential therapeutic applications.

Check Digit Verification of cas no

The CAS Registry Mumber 77511-23-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,1 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77511-23:
(7*7)+(6*7)+(5*5)+(4*1)+(3*1)+(2*2)+(1*3)=130
130 % 10 = 0
So 77511-23-0 is a valid CAS Registry Number.

ONE-POT CYCLIZATION OF A PEPTIDE BY THE USE OF (5-NITROPYRIDYL)DIPHENYL PHOSPHINATE: THE SYNTHESIS OF CYCLIC DECAPEPTIDE GRAMICIDIN S

Mukaiyama, Teruaki,Kamekawa, Kenichi,Watanabe, Yutaka

, p. 1367 - 1370 (2007/10/02)

One-pot synthesis of gramicidin S, cyclic decapeptide, was successfully achieved by treatment of the corresponding linear decapeptide with (5-nitropyridyl)diphenyl phosphinate, a new condensing reagent, in pyridine.Similarly, the phosphinic ester can be successfully employed in the Young test as well as syntheses of dipeptides.
