Modulators of Rho C activity

A method for modulating the activity of a Rho C enzyme, comprising:

• contacting said Rho C enzyme with an effective amount of a compound of formula 1:
• 14
• wherein R1 is H, lower alkyl, aralkyl, aryl-lower alkenyl, or —(CH2)nCH(R7)NR8R9, where n is 0-6 inclusive, R7 is H, lower alkyl, aryl, or aralkyl, R8 is H, lower alkyl, cyclo-alkyl, aryl, or aralkyl, and R9 is R, RCO—, ROCO—, or RNHCO—, where R is lower alkyl, cycloalkyl, aryl, or aralkyl, wherein aryl and aralkyl are substituted with 0-3 substituents selected from the group consisting of lower alkyl, halo, nitro, —OH, trifluoromethyl, or lower alkoxy;
• R2 is lower alkyl, aryl, aralkyl, or —(CHR10)n—(CO)—R11, wherein m is 0-4, R10 is H or lower alkyl, and R11 is lower alkyl, cycloalkyl, aryl, or aralkyl, wherein aryl and aralkyl are substituted with 0-3 substituents selected from the group consisting of lower alkyl, halo, nitro, —OH, trifluoromethyl, or lower alkoxy;
• R3, R4, R5, and R6, are each independently H, lower alkyl, halo, nitro, OH, lower alkoxy, NH2, lower alkylamino, di(lower alkylamino), trifluoromethyl, or SH;
• or a pharmaceutically acceptable salt thereof.

A method for treating a disorder mediated by RhoC, comprising:

• administering to a subject having a RhoC-mediated disorder an effective amount of a compound of formula 1:
• 15
• wherein R1 is H, lower alkyl, aralkyl, aryl-lower alkenyl, or —(CH2)nCH(R7)NR8R9, where n is 0-6 inclusive, R7 is H, lower alkyl, aryl, or aralkyl, R8 is H, lower alkyl, cyclo-alkyl, aryl, or aralkyl, and R9 is R, RCO—, ROCO—, or RNHCO—, where R is lower alkyl, cycloalkyl, aryl, or aralkyl, wherein aryl and aralkyl are substituted with 0-3 substituents selected from the group consisting of lower alkyl, halo, nitro, —OH, trifluoromethyl, or lower alkoxy;
• R2 is lower alkyl, aryl, aralkyl, or —CHR10)m—(CO)—R11, wherein m is 0-4, R10 is H or lower alkyl, and R11 is lower alkyl, cycloalkyl, aryl, or aralkyl, wherein aryl and aralkyl are substituted with 0-3 substituents selected from the group consisting of lower alkyl, halo, nitro, —OH, trifluoromethyl, or lower alkoxy;
• R3, R4, R5, and R6, are each independently H, lower alkyl, halo, nitro, OH, lower alkoxy, NH2, lower alkylamino, di(lower alkylamino), trifluoromethyl, or SH;
• or a pharmaceutically acceptable salt thereof.

A composition for modulating the activity of a Rho C enzyme, said composition comprising:

• an effective amount of a compound of formula 1
• 16
• wherein R1 is H, lower alkyl, aralkyl, aryl-lower alkenyl, or —(CH2)nCH(R7)NR8R9, where n is 0-6 inclusive, R7 is H, lower alkyl, aryl, or aralkyl, R8 is H, lower alkyl, cyclo-alkyl, aryl, or aralkyl, and R9 is R, RCO—, ROCO—, or RNHCO—, where R is lower alkyl, cycloalkyl, aryl, or aralkyl, wherein aryl and aralkyl are substituted with 0-3 substituents selected from the group consisting of lower alkyl, halo, nitro, —OH, trifluoromethyl, or lower alkoxy;
• R2 is lower alkyl, aryl, aralkyl, or —(CHR10)m—(CO)—R11, wherein m is 0-4, R10 is H or lower alkyl, and R11 is lower alkyl, cycloalkyl, aryl, or aralkyl, wherein aryl and aralkyl are substituted with 0-3 substituents selected from the group consisting of lower alkyl, halo, nitro, —OH, trifluoromethyl, or lower alkoxy;
• R3, R4, R5, and R6, are each independently H, lower alkyl, halo, nitro, OH, lower alkoxy, NH2, lower alkylamino, di(lower alkylamino), trifluoromethyl, or SH;
• or a pharmaceutically acceptable salt thereof.
