- Discovery of novel and potent aryl diamines as leukotriene A4 hydrolase inhibitors
-
The synthesis and biological evaluation of a series of aryl diamines as inhibitors of LTA4-h inhibitors are described. The optimization which led to the identification of the optimal para-substitution on the diphenyl ether moiety and diamine spacer is discussed. The resulting compounds such as 3l have excellent enzyme and cellular potency as well as desirable pharmacokinetic properties.

- Derivatives of quinoline as inhibitors for MEK
-
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.
