Abstract: A method of manufacturing a proton-conductive polymer electrolyte membrane using polyvinyl alcohol (PVA) as a base material and having excellent proton conductivity and methanol blocking properties is provided. The method includes: heat-treating a precursor membrane including PVA and a water-soluble polymer electrolyte having a proton conductive group to proceed crystallization of the PVA; and chemically crosslinking the heat-treated precursor membrane with a crosslinking agent reactive with the PVA, to form a polymer electrolyte membrane in which a crosslinked PVA is a base material and protons are conducted through the electrolyte retained in the base material. The content of a water-soluble polymer except the PVA and the water-soluble polymer electrolyte in the precursor membrane is in a weight ratio of less than 0.1 with respect to the PVA.

Abstract: 3-[(1S)-1-(2-fluorobiphenyl-4-yl)ethyl]-5-[[amino(morpholin-4-yl)methylene]amino]isoxazole is an isoxazole compound useful as a therapeutic agent for an autoimmune disease. The isoxazole compound can be stabilized by using an antioxidant such as a metabisulfite, bisulfite, sulfite or dibutylhydroxytoluene. A pharmaceutical composition for oral administration comprising the isoxazole compound and the antioxidant is an excellent pharmaceutical composition, since the isoxazole compound contained in the composition is stabilized.
