140894-62-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 140894-62-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,9 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 140894-62:
(8*1)+(7*4)+(6*0)+(5*8)+(4*9)+(3*4)+(2*6)+(1*2)=138
138 % 10 = 8
So 140894-62-8 is a valid CAS Registry Number.

Design, synthesis, and structure-activity relationships of unsubstituted piperazinone-based transition state factor Xa inhibitors

Huang, Wenrong,Naughton, Mary Ann,Yang, Hua,Su, Ting,Dam, Suiko,Wong, Paul W.,Arfsten, Ann,Edwards, Susan,Sinha, Uma,Hollenbach, Stanley,Scarborough, Robert M.,Zhu, Bing-Yan

, p. 723 - 728 (2007/10/03)

A series of novel transition state factor Xa inhibitors containing a variety of lactam ring systems as central templates was synthesized in an expedient manner and allowed for a great deal of structural variability. Among them, the piperazinone-based inhibitors were found to be not only active against factor Xa but also selective over thrombin. Optimization of the P4 moiety yielded several potent compounds with IC50 below 1 nM against factor Xa.

Example 1, (2008/06/13)

Novel compounds of formula I: including its pharmaceutically acceptable isomers, salts, hydrates, solvates and prodrug derivatives having activity against mammalian factor Xa are described. Compositions containing such compounds are also described. The co

Synthesis of a homologous series of ketomethylene arginyl pseudodipeptides and application to low molecular weight hirudin-like thrombin inhibitors

DiMaio,Gibbs,Lefebvre,Konishi,Munn,Shi Yi Yue,Hornberger

, p. 3331 - 3341 (2007/10/02)

The design of low molecular weight thrombin inhibitors IIa-d (hirutonins) that bind concurrently with the enzyme's catalytic site and auxiliary 'anion- binding exosite' for fibrinogen recognition is reported. A practical synthesis of the required homologo
