Abstract

Disclosed are compounds of Formula (I) and pharmaceutically acceptable salts and solvates thereof. Such compounds are MEK inhibitors and are useful in the treatment of proliferative diseases, such as cancer. Also disclosed are pharmaceutical compositions containing such compounds as well as methods of using the compounds and compositions of the invention in the treatment of cancer.

where the alkyl, alkenyl, alkynyl, cycloalkyl, heteroaryl, and heterocycloalkyl are independently optionally substituted with one, two, three, four, five, six or seven groups independently selected from halo, alkyl, haloalkyl, nitro, optionally substituted cycloalkyl, optionally substituted heterocycloalkyl, optionally substituted aryl, optionally substituted arylalkyl, optionally substituted heteroaryl, —OR8, —NR8R8′, —NR8S(O)2R9, —CN, —S(O)mR9, —C(O)R8, —C(O)OR8, —C(O)NR8R8′, —NR8C(O)NR8′R8″, —NR8C(O)OR8′ and —NR8C(O)R8′;
or one of R1 and R2 together with the carbon to which they are attached, R3 and R4 together with the carbon to which they are attached, and R5 and R6 together with the carbon to which they are attached form C(O) or C(═NOH);
m is 0, 1, or 2;
R7 is hydrogen, halo or alkyl;
R8, R8′ and R8″ are independently selected from hydrogen, hydroxy, optionally substituted alkoxy, alkyl, alkenyl, alkynyl, aryl, cycloalkyl, heteroaryl, and heterocycloalkyl;
where the alkyl, alkenyl, alkynyl, aryl, cycloalkyl, heteroaryl, and heterocycloalkyl are independently optionally substituted with one, two three, four, or five groups independently selected from alkyl, halo, hydroxy, hydroxyalkyl, optionally substituted alkoxy, alkoxyalkyl, haloalkyl, carboxy, alkoxycarbonyl, alkenyloxycarbonyl, optionally substituted cycloalkyl, optionally substituted cycloalkyloxycarbonyl, optionally substituted aryl, optionally substituted aryloxy, optionally substituted aryloxycarbonyl, optionally substituted arylalkyl, optionally substituted arylalkyloxy, optionally substituted arylalkyloxycarbonyl, nitro, cyano, optionally substituted heterocycloalkyl, optionally substituted heteroaryl, —S(O)nR31 (where n is 0, 1, or 2 and R31 is optionally substituted alkyl, optionally substituted aryl, optionally substituted heterocycloalkyl, or optionally substituted heteroaryl), —NR34SO2R34a (where R34 is hydrogen or alkyl and R34a is alkyl, alkenyl, cycloalkyl, aryl, heteroaryl, or heterocycloalkyl), —SO2NR35R35a (where R35 is hydrogen or alkyl and R35a is alkyl, alkenyl, cycloalkyl, aryl, heteroaryl, or heterocycloalkyl), —NR32C(O)R32a (where R32 is hydrogen or alkyl and R32a is alkyl, alkenyl, alkoxy, or cycloalkyl), —NR30R30′ (where R30 and R30′ are independently hydrogen, alkyl, or hydroxyalkyl), and —C(O)NR33R33a (where R33 is hydrogen or alkyl and R33a is alkyl, alkenyl, alkynyl, or cycloalkyl);
and
R9 is alkyl, alkenyl, alkynyl, aryl, cycloalkyl, heteroaryl, and heterocycloalkyl;
where the alkyl, alkenyl, alkynyl, aryl, cycloalkyl, heteroaryl, and heterocycloalkyl are independently optionally substituted with one, two, three, four, or five groups selected from halo, hydroxy, alkyl, haloalkyl, haloalkoxy, amino, alkylamino, and dialkylamino;
