A compound of formula IV: as well as drug-linkers and conjugates comprising this compound, and the use of the conjugates in treating cancer.

Azetidobenzodiazepine dimers and conjugates comprising them for use in the treatment of cancer

A compound which is either A: and salts and solvates thereof, as well as their conjugates with a cell-binding agent.

Pyrrolobenzodiazepines and conjugates thereof

Conjugates of an antibody that binds to CD25 with PBD dimers.

Pyrrolobenzodiazepine-antibody conjugates

Conjugates of an antibody that binds to CD19 with PBD dimers.

A compound which is either A: or B: and salts and solvates thereof, as well as their conjugates with a cell-binding agent.

Site-specific antibody-drug conjugates are described, in particular conjugates comprising pyrrolobenzodiazepines (PBDs) having a labile protecting group in the form of a linker. The site of conjugation, along with modification of the antibody moiety, allows for improved safety and efficacy of the ADC.

Site-specific antibody-drug conjugates

This invention relates to peptidomimetic linkers and anti-body drug conjugates thereof pharmaceutical compositions containing them, and to their use in therapy for the prevention treatment of cancer.

Peptidomimetic compounds and antibody-drug conjugates thereof

The disclosure provides conjugates of an isolated humanized anti-CD22 antibody and PBD dimers.

Pyrrolobenzodiazepine-anti-CD22 antibody conjugates

A conjugate of formula (I) wherein Ab is a modified antibody having at least one free conjugation site on each heavy chain. 

Pyrrolobenzodiazepine conjugates

A compound with the formula I: (I) and salts and solvates thereof, wherein: R&#x2033; is a group of formula II: (II) where each of n and m are independently selected from 1, 2 and 3. 

Pyrrolobenzodiazepines and conjugates thereof as antitumour agents

A conjugate of formula I:L-(D)&#x2003;&#x2003;(1) wherein L is a Ligand unit, Dis a Drug Linker unit of formula II:  wherein either: (a) Rand Rform a nitrogen-carbon double bond between the nitrogen and carbon atoms to which they are bound; or (b) Ris OH, and Ris:  p is an integer of from 1 to 20.

Pyrrolobenzodiazepine antibody conjugates

A conjugate comprising the following topoisomerase inhibitor derivative (A*): with a linker for connecting to a Ligand Unit, wherein the linker is attached in a cleavable manner to the amino residue. The Ligand Unit is preferably an antibody. Also provided is A* with the linking unit attached, and intermediates for their synthesis, as well as the released warhead.

Compounds and conjugates thereof

A compound of formula I and salts and solvates thereof, wherein: Rand Rare independently selected from H, R, OH, OR, SH, SR, NH, NHR, NRR', nitro, MeSn and halo; where R and R&#x2032; are independently selected from optionally substituted Calkyl, Cheterocyclyl and Caryl groups; Ris selected from H, R, OH, OR, SH, SR, NH, NHR, NRR&#x2032;, nitro, MeSn and halo; R&#x2033; is a Calkylene group, which chain may be interrupted by one or more heteroatoms, e.g. O, S, NR(where Ris H or Calkyl), and/or aromatic rings, e.g. benzene or pyridine; Y and Y&#x2032; are selected from O, S, or NH; R, R, Rare selected from the same groups as R, Rand Rrespectively; Ris selected from OH, OR, where Ris Calkyl; and Ris a linker for connection to a cell binding agent. 

A conjugate of formula (A): where Y is selected from a single bond, and a group of formulae A1 or A2: where N shows where the group binds to the N10 of the PBD moiety;
