Application Number:	11/829,217
Claims:	1. A method for treating asthma comprising administering a therapeutically effective amount of 3-{4-Methyl-3-[methyl-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-amino]-piperidin-- 1-yl}-3-oxo-propionitrile or a pharmaceutically acceptable salt thereof to a mammal. 2. The method of claim 1 comprising administering a therapeutically effective amount of a pharmaceutically acceptable salt of 3-{4-Methyl-3-[methyl-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-amino]-piperidin-- 1-yl}-3-oxo-propionitrile to the mammal. 3. The method of claim 2 wherein the pharmaceutically acceptable salt is selected from the group consisting of hydrochloride, hydrobromide, hydroiodide, nitrate, sulfate, bisulfate, phosphate, acid phosphate, acetate, lactate, citrate, acid citrate, tartrate, bitartrate, succinate, maleate, fumarate, gluconate, saccharate, benzoate, methanesulfonate, ethanesulfonate, benzenesulfonate, p-toluenesulfonate and pamoate salts. 4. The method of claim 1 wherein the therapeutically effective amount of 3-{4-Methyl-3-[methyl-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-amino]-piperidin-- 1-yl}-3-oxo-propionitrile or pharmaceutically acceptable salt thereof is administered orally. 5. The method of claim 1 wherein the mammal is a human. 6. The method of claim 1 further comprising administering one or more additional agents which modulate a mammalian immune system or antiinflamatory agents to the mammal. 7. A method for treating psoriasis comprising administering a therapeutically effective amount of 3-{4-Methyl-3-[methyl-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-amino]-piperidin-- 1-yl}-3-oxo-propionitrile or a pharmaceutically acceptable salt thereof to a mammal. 8. The method of claim 7 comprising administering a therapeutically effective amount of a pharmaceutically acceptable salt of 3-{4-Methyl-3-[methyl-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-amino]-piperidin-- 1-yl}-3-oxo-propionitrile to the mammal. 9. The method of claim 8 wherein the pharmaceutically acceptable salt is selected from the group consisting of hydrochloride, hydrobromide, hydroiodide, nitrate, sulfate, bisulfate, phosphate, acid phosphate, acetate, lactate, citrate, acid citrate, tartrate, bitartrate, succinate, maleate, fumarate, gluconate, saccharate, benzoate, methanesulfonate, ethanesulfonate, benzenesulfonate, p-toluenesulfonate and pamoate salts. 10. The method of claim 7 wherein the therapeutically effective amount of 3-{4-Methyl-3-[methyl-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-amino]-piperidin-- 1-yl}-3-oxo-propionitrile or pharmaceutically acceptable salt thereof is administered orally. 11. The method of claim 7 comprising administering a therapeutically effective amount of 3-{4-Methyl-3-[methyl-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-amino]-piperidin-- 1-yl}-3-oxo-propionitrile to the mammal. 12. The method of claim 7 further comprising administering one or more additional agents which modulate a mammalian immune system or antiinflamatory agents to the mammal.
