    • PURPOSE: Provided is a novel amino acid salt of aceclofenac including aceclofenac riginate and aceclofenac argininate, which has significantly improved solubility and bioavailability compared to the parent material, aceclofenac. CONSTITUTION: The amino acid salt of aceclofenac is represented by the following formula I. In formula I, R is H or H2NC=NH-, m is an integer of 3 or 4, an n is an integer of 1-5. The aminoacid salt of aceclofenac is prepared by the method comprising a step of reacting aceclofenac with an amino acid represented by the following formula II in an equivalent ratio of 1:1-1:5.
    • 目的:提供醋氯芬酸的新型氨基酸盐,包括醋氯芬酸精氨酸和醋氯芬酸精氨酸,与母体药物醋氯芬酸相比,其具有显着改善的溶解度和生物利用度。 组成:醋氯芬酸的氨基酸盐由下式I表示。在式I中,R为H或H 2 NC = NH-,m为3或4的整数,n为1-5的整数。 醋氯芬酸的氨基酸盐通过包括如下步骤的方法制备,所述方法包括以1:1-1:5的当量比使醋氯芬酸与由下式II表示的氨基酸反应的步骤。
