It has now been discovered that a high therapeutic effect in treating various disorders associated with enhanced activity of kinase p38 may be achieved by using a potent p38? kinase inhibitor compound which also has inhibitory activity against p38?. Furthermore, reducing the activities of both kinase p38? and kinase p38? without reducing the activity of a kinase p38? to such an extent that undesired side effects are observed upon administration to a subject having a disorder associated with enhanced activity of kinase p38 has been discovered to be achievable by modifying inhibitors of p38? such that the modification engenders inhibitory activity against p38?. Described are compounds with activity against p38? and p38?.； Disclosed are methods of using described compounds and compositions to modulate a stress activated protein kinase (SAPK) system with an active compound, wherein the active compound exhibits inhibition of the p38? and p38? MAPKs. Also disclosed are methods for identifying compounds which inhibit p38? and p38? MAPKs and which can modulate a stress activated protein kinase (SAPK) system.
