172349-26-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 172349-26-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,3,4 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 172349-26:
(8*1)+(7*7)+(6*2)+(5*3)+(4*4)+(3*9)+(2*2)+(1*6)=137
137 % 10 = 7
So 172349-26-7 is a valid CAS Registry Number.

Structure-based organic synthesis of unnatural aeruginosin hybrids as potent inhibitors of thrombin

Hanessian, Stephen,Ersmark, Karolina,Wang, Xiaotian,Del Valle, Juan R.,Blomberg, Niklas,Xue, Yafeng,Fjellstroem, Ola

, p. 3480 - 3485 (2007)

Based on X-ray crystallographic data of complexes of chlorodysinosin A with the enzyme thrombin, a series of analogs were synthesized varying the nature of the P1, P2, and P3 pharmacophoric sites and the central octahydroindole carboxyamide core. In general, introduction of a hydrophobic substituent on the d-leucine amide residue dramatically improved the inhibition of the enzyme. This is rationalized based on a better fit of the P3 subunit in the hydrophobic S3 enzyme site. Single digit nanomolar inhibition expressed as IC50 was observed for several analogs.
