Methods of treatment
This disclosure relates to use of certain aldehyde compounds for treating pulmonary fibrosis, hypoxia, and connective tissue and autoimmune disease such as scleroderma, lupus, arthritis and related conditions in a mammal.
1. A method of treating idiopathic pulmonary fibrosis in a patient, the method comprising administering to said patient a therapeutically effective amount of a compound selected from:
(S)-2-hydroxy-6-((1-(6-methoxynicotinoyl)piperidin-2-yl)methoxy)benzaldehyde; and
2-hydroxy-6-((2-(1-isopropyl-1H-pyrazol-5-yl)pyridin-3-yl)methoxy)benzaldehyde; or
a pharmaceutically acceptable salt thereof.
2. A method of treating idiopathic pulmonary fibrosis in a patient, the method comprising administering to said patient a therapeutically effective amount of a compound, wherein the compound is 2-hydroxy-6-((2-(1-isopropyl-1H-pyrazol-5-yl)pyridin-3-yl)methoxy)benzaldehyde.
3. The method of claim 2 , wherein the patient is administered 500 to 1000 mg of 2-hydroxy-6-((2-(1-isopropyl-1H-pyrazol-5-yl)pyridin-3-yl)methoxy)benzaldehyde per day.
4. The method of claim 2 , wherein the patient is administered 600 to 900 mg of 2-hydroxy-6-((2-(1-isopropyl-1H-pyrazol-5-yl)pyridin-3-yl)methoxy)benzaldehyde per day as a single dose.
5. The method of claim 2 , wherein the compound is an ansolvate characterized by at least two X-ray powder diffraction peaks (Cu Kα radiation) selected from 13.37°, 14.37°, 19.95° and 23.92° 2θ (each ±0.2° 2θ).
6. The method of claim 5 , wherein the compound is characterized by at least three X-ray powder diffraction peak (Cu Kα radiation) selected from 13.37°, 14.37°, 19.95° and 23.92° 2θ (each ±0.2° 2θ).
