Description | A771726, also known as a-77-1726m1, belongs to the class of organic compounds known as trifluoromethylbenzenes. These are organofluorine compounds that contain a benzene ring substituted with one or more trifluoromethyl groups. A771726 is an extremely weak basic (essentially neutral) compound (based on its pKa). A771726 is a metabolite of leflunomide. Leflunomide is a medication of the DMARD type, used in active moderate to severe rheumatoid arthritis and psoriatic arthritis. It is a pyrimidine synthesis inhibitor. |
