Abstract: An in situ film-forming methyl acetate-based solution of at least one absorbable, segmented block copolymer with amorphous and semi-crystalline segments contains at least one bioactive agent which exhibits antimicrobial, anti-inflammatory, antiviral, anesthetic, hemostatic, and/or antineoplastic activity. The absorbable polymers can be a polyaxial copolyester, polyether-ester and polyether-ester urethane. The solution can be applied (e.g., sprayed or swabbed) onto animal and human skin or accessible body cavities to prevent or treat one or more disorders preventable or treatable by the bioactive agent therein.

Abstract: A method for modifying a protein or polypeptide is disclosed which includes the steps of dispersing a protein or polypeptide in an essentially non-aqueous medium and peracylating the protein or polypeptide with a cyclic anhydride having a carbon chain substituent selected from the group consisting of alkyl and alkenyl groups. Most preferably, the cyclic anhydride is succinic anhydride, although glutaric anhydride may also be employed. Preferably, the step of peracylating the protein or polypeptide is performed in the presence of an acid catalyst, most preferably &rgr;-toluene sulfonic acid. The resultant modified protein or polypeptide may be employed in numerous applications including drug delivery, absorbable sutures, and thermoplastic films and molded articles.
