The invention relates to certain compounds of formula (I) (I) wherein Y is an electron-withdrawing group; Q is (formula) Z is a leaving group; J is NR5, with R5 being hydrogen or a substituted or unsubstituted alkyl, alkenyl, alkynyl or aryl group. R1 to R4 optional substituents and m is an integer between 1 and 12; n is an integer between 0 and 4; o is between 0 and 4. These compounds are useful as linkers for realisably joining a targeting moiety such as an antibody to a "cargo" compound such as a drug, particularly an anti-cancer drug. The invention also relates to conjugates of a targeting moiety and a drug utilising the linker, to methods of synthesis of the linker and to processes for the production of the conjugate. The use of the conjugate in the treatment of disease such as cancer is also disclosed.

A series of self-immolative linkers containing a thiol-reactive group at one end and a hydroxyl- or amine-reactive group at the other were prepared. The utility of these reagents for preparations of bioconjugates was explored by reacting the linkers with appropriately functionalized model drugs and peptides. Degradation studies of a series of conjugates with different linkers reveal that the structure

The invention features polynucleotide constructs containing one or more components (i) containing a disulfide linkage, where each of the one or more components is attached to an internudeotide bridging group or a terminal group of the polynucleotide construct, and each of the one or more components (i) contains one or more bulky groups proximal to the disulfide group. The invention also features polynucleotide constructs containing one or more components (i) containing a disulfide linkage, where each of the one or more components (i) is attached to an internudeotide bridging group or a terminal group of the polynucleotide construct, and each of the one or more components (i) contains at least 4 atoms in a chain between the disulfide linkage and the phosphorus atom of the internudeotide bridging group or the terminal group; and where the chain does not contain a phosphate, an amide, an ester, or an alkenylene. The invention also features methods of delivering a polynucleotide to a cell using the polynucleotide constructs of the invention.
