176963-46-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 176963-46-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,9,6 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 176963-46:
(8*1)+(7*7)+(6*6)+(5*9)+(4*6)+(3*3)+(2*4)+(1*6)=185
185 % 10 = 5
So 176963-46-5 is a valid CAS Registry Number.

Hydroxyindole derivatives as inhibitors of IL-1 generation. II. Synthesis and pharmacological activities of (E)3-(7-hydroxy-6-methoxyindole-4-yl)-2-methylpropenoic acid derivatives

Tanaka,Okita,Akamatsu,Chiba,Obaishi,Nagakura,Sakurai,Yamatsu

, p. 187 - 198 (2007/10/03)

A series of (E)-3-(7-hydroxy-6-methoxyindole-4-yl)-2-methylpropenoic acid derivatives was prepared and the inhibitory activities of its members on IL-1 generation were evaluated in an in vitro system using exudate cells from the rat carboxy-methyl cellulose (CMC) induced air-pouch model. All the compounds in this new series were found to be inhibitors of IL-1 generation. In particular, the methoxy-substituted 2-phenyl compounds 28d-f were the most potent inhibitors of IL-1 generation (eg, 28d: IC50 = 0.8 μ,M). The compounds in this series also inhibited IL-1α and IL-1β generations in an in vitro system using human monocytes stimulated with LPS (eg, 28b: IC50 = 1.4 μM (IL-1α) and 0.9 μM (IL-1β)).
