摘要:
The invention relates to compounds of general structure (1 ): Q-(L 1 ) n -(L 2 ) o -(L 3 ) p -(L 4 ) q -D, wherein Q is a click probe; D is a cytotoxin containing an enediyne moiety; L 1 , L 2 , L 3 and L 4 are each individually linkers that together link Q to D; n, o, p and q are each individually 0 or 1, provided that n + o + p + q = 1, 2, 3 or 4, wherein D comprises a functional moiety (21), wherein R 12 = C 1-3 -alkyl, the wavy line indicates the connection to the remainder of the cytotoxin, and wherein D is conjugated to (L 4 ) q by replacing the amine H atom, and to conjugates obtainable by reacting the compound according to the invention with a protein comprising a click probe F capable of reacting with click probe Q in a click reaction. The invention further relates to a bioconjugate according to general structure (2): Pr-[(L 6 )-Z-(L 1 ) n -(L 2 ) o -(L 3 ) p -(L 4 ) q -D] xx , wherein Z is a connecting group that is formed in a click reaction, L 6 is a linker that links Z to Pr and Pr is a (glyco)protein.

摘要:
Disclosed are linkers containing a 2,3-disubstituted succinic group, or 2-monosubstituted, or 2,3-disubstituted fumaric or maleic (trans (E)- or cis (Z)-butenedioic), or acetylenedicarboxyl group for conjugation of a cytotoxie agent, and/or one or more different functional molecules per linker to a cell-binding molecule, through bridge linking pairs of thiols on the cell-binding molecule specifically. Also disclosed are methods of making such linkers, and of using such linkers in making homogeneous conjugates, as well as of application of the conjugates in treatment of cancers, infections and autoimmune disorders.

A formulstion comprising (i) an immunoconjugate of the following formula (I): wherein Ab is an anti-GCC antibody molecule, X is a linker component, Z is a therapeutic agent, and m is an integer from 1 - 15, or a pharmaceutically acceptable salt thereof, (ii) polysorbate 20, and (iii) histidine or a salt thereof.
摘要:
The present invention relates to conjugates, in particular antibody-drug conjugates and immunotoxins, having the formula (I): A-(L-D)p or a pharmaceutically acceptable salts or solvates thereof, wherein A is an antibody that selectively binds FAP; L is a linker; D is a drug comprising a cytolysin or a Nigrin-b A-chain; and p is 1 to 10, and to use of such conjugates in the therapeutic treatment of tumors. Methods of producing such conjugates and components for use in such methods are disclosed.
摘要:
The present invention relates to duocarmycin-containing antibody-drug conjugates (ADCs) for use in the treatment of human solid tumours expressing HER2, wherein the human solid tumour expressing HER2 is endometrial cancer, in particular uterine serous carcinoma (USC). In particular, the present invention relates to duocarmycin-containing ADCs for use in the treatment of endometrial cancer, notably USC, with HER2 IHC 2+ or 1+ and HER2 FISH negative tumour tissue status.
