203640-35-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 203640-35-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,6,4 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 203640-35:
(8*2)+(7*0)+(6*3)+(5*6)+(4*4)+(3*0)+(2*3)+(1*5)=91
91 % 10 = 1
So 203640-35-1 is a valid CAS Registry Number.

METHODS OF INHIBITING BACTERIAL VIRULENCE AND COMPOUNDS RELATING THERETO

-

Paragraph 0175, (2017/01/31)

The present invention relates to compounds and methods for the treatment of bacterial infections. Because their mechanism of action does not involve killing of bacteria or inhibiting their growth, the potential for these compounds to induce drug resistance in bacteria is minimized. Through inhibiting bacterial virulence, the present invention provides a novel means of treating bacterial infections.

Design and synthesis of procollagen C-proteinase inhibitors

Turtle, Eric,Chow, Nicholas,Yang, Charles,Sosa, Sergio,Bauer, Udo,Brenner, Mitch,Solow-Cordero, David,Ho, Wen-Bin

, p. 7397 - 7401 (2013/02/22)

Non-peptidic inhibitors of procollagen C-proteinase (PCP) were designed from substrate leads. Compounds were optimized for potency and selectivity, with N-substituted aryl sulfonamide hydroxamates having the best combination of these properties. Compounds

Highly selective and orally active inhibitors of type IV collagenase (MMP-9 and MMP-2): N-sulfonylamino acid derivatives

, p. 640 - 649 (2007/10/03)

Various N-sulfonylamino acid derivatives were synthesized and evaluated for their in vitro and in vivo activities to inhibit type IV collagenase (MMP-9 and MMP-2). When the amino acid residue and the sulfonamide moiety were modified, their inhibitory activities were greatly affected by the structure of the sulfonamide moiety. A series of aryl sulfonamide derivatives containing biaryl, tetrazole, amide, and triple bond were found to be potent and highly selective inhibitors of MMP-9 and MMP-2. In addition, these compounds were orally active in animal models of tumor growth and metastasis. These results revealed the potential of the N-sulfonylamino acid derivatives as a new type of candidate drug for the treatment of cancer.
