22303-31-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22303-31-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,3,0 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22303-31:
(7*2)+(6*2)+(5*3)+(4*0)+(3*3)+(2*3)+(1*1)=57
57 % 10 = 7
So 22303-31-7 is a valid CAS Registry Number.

Design, synthesis and biological evaluation of novel thiazole-based derivatives as human Pin1 inhibitors

Pin1 is a peptidyl prolyl cis-trans isomerase (PPIase) and inhibiting Pin1 is a potential way for discovering anti-tumor agents. With an aim to find potent Pin1 inhibitors with a novel scaffold, a series of thiazole derivatives with an alicyclic heterocycles on the 2-position were designed, synthesized and tested against human Pin1. Compound 9p bearing a 2-oxa-6-azaspiro [3,3] heptane moiety on the thiazole scaffold was identified as the most potent Pin1 inhibitor of this series with an IC50 value of 0.95 μM. The structure-activity relationship (SAR) and molecular modeling study indicated that introducing an alicyclic ring with an H-bond acceptor would be a viable way to improve the binding affinity.
