Title:

TEMPERATURE-RESPONSIVE AND BIODEGRADABLE POLYDEPSIPEPTIDE AND PROCESS FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/2005/056637

Kind Code:

A1

Abstract:

A polydepsipeptide which combines temperature responsiveness with biodegradability and is suitable for use as a medical material. The polydepsipeptide is represented by the general formula (I): [Chemical formula 1] (I) (wherein R¹ represents C_1-6 alkyl, hydroxylated C_1-6 alkyl, or C_1-6 alkyl substituted by C_1-3 alkoxy; R² represents hydrogen or methyl; x is an integer of 4 or larger; y is an integer of 0 or larger; and n is 1 or 2). Also provided is a use of the polydepsipeptide.
