Title:
ANTIBODY-DRUG CONJUGATE PRECURSOR AND INTERMEDIATE FOR SYNTHESIS THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/163234
Kind Code:
A1
Abstract:
The present invention provides: a method for improving the stability of an antibody-drug conjugate in vivo; and a conjugate precursor for producing a stabilized antibody-drug conjugate. More specifically, the present invention provides: an antibody-drug conjugate precursor represented by general formula (I): [wherein Z represents a reactive group capable of reacting with a functional group present in an antibody or a modified antibody; D represents an antitumor drug residue having such a structure that one hydrogen atom or one hydroxyl group is removed from an arbitrary position in an antitumor drug molecule, an analogue of the antitumor drug molecule or a derivative of the antitumor drug molecule or the analogue; and L represents a linker that links Z to D; wherein at least one of D and L has at least one lactonyl group as a substituent or a protecting group at an arbitrary position] or a salt thereof; an intermediate for the synthesis of the antibody-drug conjugate precursor or the salt thereof, or a salt of the intermediate; and others.
