General Description
N-(tert-butoxycarbonyl)-L-tyrosyl-D-methionylglycyl-4-nitro-3-phenyl-L-alanyl-L-prolinamide is a peptide chemical compound composed of amino acids tyrosine, methionine, glycine, alanine, and proline. It is often used in pharmaceutical research and as a biochemical tool for studying the structure and function of proteins. The N-terminal t-butoxycarbonyl (Boc) group is a protective group that can be removed under acidic conditions, allowing for the synthesis and manipulation of the peptide. The presence of a nitro group in the structure may contribute to its potential biological activity or pharmacological properties. Overall, this complex chemical compound serves as a valuable tool for studying and developing new drugs and treatments.
Check Digit Verification of cas no
The CAS Registry Mumber 73385-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,3,8 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 73385-91:
(7*7)+(6*3)+(5*3)+(4*8)+(3*5)+(2*9)+(1*1)=148
148 % 10 = 8
So 73385-91-8 is a valid CAS Registry Number.

Peripherally acting enkephalin analogues. 1. Polar pentapeptides
Hardy,Lowe,Sang,Simpkin,Wilkinson,Follenfant,Smith
, p. 960 - 966 (2007/10/02)
The design, synthesis, and biological activity of a series of highly polar enkephalin-related pentapeptides are reported. These analogues incorporate structural features that exclude them from the central nervous system and thereby restrict their action to peripherally located receptors. Hydrophilic analogues were obtained by introduction of polar D-amino acid residues at position 2 and, in certain cases, by conversion of the N-terminal amino group of the Tyr residue to a guanidino function. The peptides were synthesized by classical solution methods. All compounds demonstrated in vitro opioid activity in the GPI and all were shown to possess antinociceptive activity in chemically induced writhing models. The analgesic effects were shown to be predominantly peripherally mediated by antagonism of antinociception with the peripheral antagonist N-methylnalorphine. Comparative data obtained in writhing and hot-plate tests were also supportive of a peripheral mode of action. Compound 13a, L-tyrosyl-D-arginylglycyl-L-4-nitrophenylalanyl-L-prolinamide (BW 443C), was identified as having a favorable pharmacological profile, indicating a high level of peripheral selectivity, and worthy of further investigation.
