Title:
NOVEL COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2022/168967
Kind Code:
A1
Abstract:
The present invention provides a novel copolymer utilizable for a drug delivery technique. More specifically, provided is a novel copolymer for a drug delivery carrier targeting a tumor. This copolymer comprises structural units shown by the following formulae (A), (B), and (C). [In the formulae, R1, R2, and R3 are the same or different and each represent a hydrogen atom or a C1-3 alkyl group; R4 represents a C1-3 alkyl group; R5 represents a hydrogen atom, a C1-18 alkyl group, an optionally substituted, 3- to 8-membered cycloalkyl group, an adamantyl group, an optionally substituted C6-18 aryl group, or an optionally substituted, 5- to 10-membered heteroaryl group; X1, X2, and X3 are the same or different and each represent an oxygen atom, a sulfur atom, or N-R7; R6 represents a hydrogen atom, a leaving group, or a linker; R7 represents a hydrogen atom or a C1-3 alkyl group; m is an integer of 1-100; and n is an integer of 0-3.]
