Abstract:Peramivir is an effective antiviral drug for treating influenza A and B with the trihydrate form as the solid serving. However, a small amount of dihydrate still exists during the manufacturing process in a few production batches. Focusing on the problem, this study successfully obtained a new dihydrate single crystal structure, a higher-quality trihydrate single crystal structure surpassing previously reported findings, and a novel anhydrous form designated as form A. A comprehensive comparison of the crystal… Show more
