Substituted 2-aminoalkylthiobenzimidazole compounds, pharmaceutical compositions thereof and methods for their use
View Patent ↗The present invention comprises the substituted 2-aminoalkylthiobenzimidazoles of formula I wherein R1-R5 and R11-R16 are hereinafter defined. These compounds, their derivatives and the pharmaceutically acceptable salts thereof are useful in the reduction of elevated blood sugar levels and are therefore useful in the treatment of hyperglycemia, diabetes, atherosclerosis and other blood sugar disorders. These compounds are particularly suitable in the treatment of type-2 diabetes.
1. The compound of formula I
wherein
R1 is H;
R2 is NR24R25;
R24 is (C 1 -C 6 )-alkylene-(C 6 -C 10 )-aryl wherein the aryl substituent may be mono- or poly-substituted by F, Cl, Br, I, CN, NO 2 , SH, OH, (C 1 -C 6 )-alkyl, O—(C 1 -C 6 )-alkyl, S—(C 1 -C 6 )-alkyl, S(O)—(C 1 -C 6 )-alkyl and S(O) 2 —(C 1 -C 6 )-alkyl;
R25 is H;
R3 is (C 2 -C 10 )-alkenyl
R4 and R5 are each independently H or ((C 1 -C 6 )-alkyl;
R11, R12, R13, R14, R15 and R16 are each H;
m is 0; and
n is 0 or 1;
or a pharmaceutically acceptable salt thereof.
