Tryptophyl-Nε-t-butoxycarbonyl-lysyl-O-t-butylthreonyl-phenylalanine is a complex peptide compound consisting of four amino acids: tryptophan, lysine, threonine, and phenylalanine. The sequence is characterized by the presence of a t-butoxycarbonyl (Boc) protecting group on the Nε-amino group of lysine, which is crucial for protecting the amino group during peptide synthesis. Additionally, the threonine residue has an O-t-butyl (t-Bu) protecting group on its hydroxyl group, which is also important for the synthesis process. This specific arrangement of amino acids and protecting groups is designed to facilitate the stepwise assembly of larger peptide or protein structures in a controlled manner, often using solid-phase peptide synthesis techniques. The compound serves as a building block in the synthesis of more complex peptides and proteins, with the protecting groups being removed at appropriate stages to allow for further reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 69994-36-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,9 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 69994-36:
(7*6)+(6*9)+(5*9)+(4*9)+(3*4)+(2*3)+(1*6)=201
201 % 10 = 1
So 69994-36-1 is a valid CAS Registry Number.

Tritiated Peptides. Part 11. Synthesis of 6>-, 11>-, and 6,11>-Somatostatin and the Metabolite 1>-Somatostatin

Allen, Mark C.,Brundish, Derek E.,Martin, John R.,Wade, Roy

, p. 2040 - 2048 (2007/10/02)

The syntheses are described of somatostatin labelled with tritium singly in the phenylalanine residues at positions 6 and 11 and doubly at residues 6 and 11 to specific radioactivities of 15.5, 13.8 and 14.1 Cim mol-1, respectively, by reductive deiodination of fully-protected precursors.Cysteine residues were proteced by S-trityl groups and the disulphide bridge was formed by iodine oxidation of the tritiated protected precursors.The purity of the products was assessed by acidic hydrolysis, ion-exchange and high-pressure liquid chromatography, and by enzymic digestion of the products modified by reduction and aminoethylation.The synthesis of the metabolite 1>-somatostatin is described.The syntheses of 6>-, 11>- and 6,11>-somatostatin are described.
