136630-91-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 136630-91-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,6,3 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 136630-91:
(8*1)+(7*3)+(6*6)+(5*6)+(4*3)+(3*0)+(2*9)+(1*1)=126
126 % 10 = 6
So 136630-91-6 is a valid CAS Registry Number.

Substrate Analogue Renin Inhibitors Containing Replacements of Histidine in P2 or Isosteres of the Amide Bond between P3 and P2 Sites

Raddatz, Peter,Jonczyk, Alfred,Minck, Klaus-Otto,Schmitges, Claus Jochen,Sombroek, Jan

, p. 3267 - 3280 (2007/10/02)

Incorporation of β-alanine or γ-aminobutyric acid in position P2 of ACHPA or LeuΨVal-based tetrapeptides gave highly active renin inhibitors (compounds V,VI, and XVII) with high specificity for renin and a remarkable stability against chymotrypsin.Replacement of the amide bond between P2 and P3 by isosteres (ketomethylenes, hydroxyethylenes, and the corresponding thio-insertion analogues) led to compounds (VIII-XIII, XVIII, and XIX) with renin inhibitory activity in the nanomolar range.Oral activity was achieved by incorporation of polar functionalities at the N-terminus of β-alanine-containing tetrapeptides.One of these compounds (XXVIII) was chosen for further studies.This inhibitor demonstrated excellent efficacy and a long duration of action after intravenous and oral administration to cynomolgus monkeys.
