Chemical structure

Chemical structure of "tesirine" (drawn in black). It consists of a pyrrolobenzodiazepine type dimer (top), which is the actual anti-cancer agent, a Val-Ala structure that can be cleaved by an enzyme to detach the anti-cancer agent from the antibody, a polyethylene glycol spacer, and a maleimide linker which is attached to a cysteine in the antibody's (rovalpituzumab's) peptide backbone, drawn blue. Each rovalpituzumab molecule has an average of two such attachments.
