CAS

  • or
H-Asp(O-tBu)-Phe-NH2 is a peptide compound consisting of three amino acids: aspartic acid (Asp), phenylalanine (Phe), and a terminal amino group (NH2). The aspartic acid residue is protected with a tert-butyl (tBu) group on its carboxylic acid side chain, which is commonly used in peptide synthesis to prevent unwanted side reactions. This specific sequence of amino acids is not a naturally occurring peptide but can be synthesized for various research purposes, such as studying protein-protein interactions or as a building block for larger peptide or protein structures. The compound's properties, such as solubility and stability, can be influenced by the presence of the tBu protecting group, which can be removed under specific conditions when needed for further reactions or studies.

5241-67-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5241-67-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,4 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5241-67:
(6*5)+(5*2)+(4*4)+(3*1)+(2*6)+(1*7)=78
78 % 10 = 8
So 5241-67-8 is a valid CAS Registry Number.

Biological activity of cholecystokinin (30-33) tetrapeptide analogues

Proskuryakova,Bespalova,Pal'keeva,Petrichenko,Pankratova,Shokhonova,Anokhina

, p. 119 - 127 (2007/10/03)

Analogues of the endogenous peptide corresponding to the 30-33 sequence of cholecystokinin (Trp-Met-Asp-Phe-NH2) were synthesized, and their biological activity was studied. It was shown that, in rats, the N-succinylated Nle2 analogu

Synthesis and biological activity of CCK26-33-related analogues modified in position 31

Marseigne,Dor,Begue,Reibaud,Zundel,Blanchard,Pelaprat,Roques

, p. 966 - 970 (2007/10/02)

The role of the amino acid in position 31 of cholecystokinin CCK26-33 in the recognition of central and peripheral receptors was investigated by replacement of methionine-31 by amino acids with side chains of various chemical nature. Thus, phen
