of the Invention In general, the invention features compounds having the formula: or a pharmaceutically acceptable salt thereof, wherein each R1 is, independently, an alkyl group having 1 to 5, inclusive, carbon atoms, an alkoxy group having 1 to 5, inclusive, carbon atoms, a halogen, amino, hydroxy, nitro, cyano, carboxyl, trifluoreomethyl, ethyl carboxylate, or a hydrogen; m is an integer between 0 and 2, inclusive,; and A is either -(CH2)n-?-R2, where n is an integer between 1 and 5, inclusive, and R is hydroxy, an alkoxy group having 1 to 5, inclusive, carbon atoms, aralkoxy (e.g., benzyloxy), aralkyl (e.g., benzyl), amino, an alkyl group having 1 to 5, inclusive, carbon atoms, an alkylamino group having 1 to 5, inclusive, carbon atoms, a dialkylamino group with each alkyl group, independently having 1 to 5, inclusive, carbon atoms, a cycloalkylamino group wherein the ring has 4 to 6, inclusive, carbon atoms (e.g., pyrrolidino, piperidino, N-methylpiperazino), or morpholino; or A is an alkyl group having 1 to 5, inclusive, carbon atoms, a hydroxyalkyl group having 1 to 5, inclusive, carbon atoms, an alkoxyalkyl group having 2 to 8, inclusive, carbon atoms, an aralkoxyalkyl having 8 to 14, inclusive, carbon atoms, an aryl group (e.g., phenyl, toluyl) having 6 to 14, inclusive, carbon atoms, an aralkyl group (e.g., benzyl, phenylethyl) having 6 to 14, inclusive, carbon atoms, and a cycloalkyl group having 3 to 12, inclusive, carbon atoms. These compounds find use as cholestokinin (or CCK) antagonists. |
