Z-Lys(BOC)-Gly-NH2 is a tripeptide compound, consisting of three amino acids: Z-Lysine (Lys), glycine (Gly), and a terminal amino group (NH2). The Z group (benzyloxycarbonyl) is a protecting group for the lysine side chain, which is crucial for preventing unwanted side reactions during peptide synthesis. The BOC group (tert-butoxycarbonyl) is another protecting group attached to the N-terminus of the peptide, which can be removed under acidic conditions to expose the free amine group for further elongation of the peptide chain. Z-Lys(BOC)-Gly-NH2 is commonly used in the synthesis of larger peptides and proteins, as it serves as a building block for constructing more complex structures.

5550-02-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5550-02-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,5 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5550-02:
(6*5)+(5*5)+(4*5)+(3*0)+(2*0)+(1*2)=77
77 % 10 = 7
So 5550-02-7 is a valid CAS Registry Number.

Process for producing triglycyl-lysine vasopressin and intermediates therefor

-

, (2008/06/13)

A new process for preparing the cyclic dodecapeptide triglycyl-lysine vasopressin of the formula STR1 which comprises the preparation of a first hexapeptide of formula Boc--Gly--Gly--Gly--Cys(Trt)--Tyr--Phe--NHNH2 and a second hexapeptide of formula H--Gln(Mbh)--Asn(Mbh)--Cys(Trt)--Pro--Lys(Boc)--Gly--NH2 by a series of condensations involving the reaction of an appropriately protected peptide unit having an activated carboxyl with an appropriately protected peptide having a free amino group. Subsequently, the first and second hexapeptides are condensed according to the azide coupling method to obtain the linear protected dodecapeptide of formula Boc--Gly--Gly--Gly--Cys(Trt)--Tyr--Phe--Gln(Mbh)--Asn(Mbh)--Cys(Trt)--Pro--Lys(Boc)--Gly--NH2 ; thereafter the linear protected dodecapeptide is transformed into the desired cyclic dodecapeptide, triglycyllysine vasopressin, by oxidizing and deprotecting processes.
