Z-Thr(Boc-Phg-O-)-OH is a complex chemical compound, which can be broken down into its constituent parts for better understanding. "Z" stands for the Z-group, a protecting group used in peptide synthesis to prevent unwanted side reactions. "Thr" represents threonine, an amino acid that is one of the building blocks of proteins. "Boc" is a tert-butyloxycarbonyl group, another protecting group used in peptide synthesis. "Phg" stands for phenylglycine, a non-natural amino acid with a phenyl group attached to the glycine backbone. "O-" indicates the presence of an oxygen atom, and "OH" signifies a hydroxyl group. In summary, Z-Thr(Boc-Phg-O-)-OH is a peptide derivative with a protected threonine residue, a phenylglycine moiety, and a hydroxyl group, which is used in the synthesis of complex peptides and proteins with specific properties.

2900-28-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2900-28-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,0 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2900-28:
(6*2)+(5*9)+(4*0)+(3*0)+(2*2)+(1*8)=69
69 % 10 = 9
So 2900-28-9 is a valid CAS Registry Number.

THE SYNTHESIS OF A Nγ-PHTHALYL-Nα-METHYL-α,γ-DIAMINOBUTYRYL CONGENER OF VIRGINIAMYCIN S1

Anteunis, M. J. O.,Auwera, C. Van der,Vanfleteren, L.,Borremans, F.

, p. 135 - 148 (2007/10/02)

A synthesis of (A2bu=α,γ-diaminobutyric acid) is reported using the very efficient coupling agent BOP-Cl (N,N'-bis(3-oxo-2-oxazolidinyl)phosphinic chloride) for imino acid peptide bond formation.The total yield is 11percent for the 5 coupling steps and one lactonization.The final step was a cyclization between residues 5 and 6, after (I) first t-Boc acidic deprotection with 85percent HCOOH of the linear precursor Z-Thr(Nα-Boc-Phg-O-)-D-Abu-Pro-MePhe-MeA2bu(γPht)-OBut followed by (ii) acidic saponification (Tfa) of the t-Bu ester.This sequence was found to be prerequisite, in view of the extreme lability of the 4-5 peptide bond under acidic conditions.
