1. A compound of formula (I)
or a pharmaceutically acceptable salt thereof.
wherein:
n is 0-1;
X and Y are independently selected from -NH-, -O-, -S-, or -NR8- where R8 is alkyl of 1-6 carbon atoms and X may additionally comprise a CH2 group;
R7 is a group (CH2)mR9 where m is 0,or an integer of from 1-3 and R9 is a substituted aryl group, an optionally substituted cycloalkyl ring of up to 10 carbon atoms, or an optionally substituted heterocyclic ring or an N-oxide of any nitrogen containing ring;
R6 is a divalent cycloalkyl of 3 to 7 carbon atoms, which may be optionally further substituted with one or more alkyl of 1 to 6 carbon atom groups; or is a divalent pyridinyl, pyimidinyl, or phenyl ring; wherein the pyridinyl, pyrimidinyl, or phenyl ring may be optionally further substituted with one or more specified groups;
R1, R2, R3 and R4 are each independently selected from hydrogen or various specified organic groups.
Compounds are useful as pharmaceuticals for the inhibition of MEK activity.
化合物的化学式(I)或其药用盐。其中:n为0-1;X和Y分别选择自-NH-、-O-、-S-或-NR8-,其中R8为1-6个碳原子的烷基,X还可以包括一个CH2基团;R7为(CH2)mR9基团,其中m为0或1-3的整数,R9为取代芳基、最多含有10个碳原子的环烷基环、或者取代的杂环环,或者任何含氮环的N-氧化物;R6为3到7个碳原子的二价环烷基,可以选择地进一步取代为一个或多个1到6个碳原子的烷基基团;或者为二价吡啶基、嘧啶基或苯基;其中吡啶基、嘧啶基或苯基可以选择地进一步取代为一个或多个特定基团;R1、R2、R3和R4分别独立选择自氢或各种指定的有机基团。这些化合物可用作抑制MEK活性的药物。
