  • BR96-DOX
CC-1065Sequence-specific minor groove of DNAInduces adenine alkylation
AnthracyclinesDNA, RNA complexesInhibit DNA and RNA synthesis by intercalating between base pairs, preventing replications
PyrrolobenzodiazepineSequence-selective. Bind to the minor groove of DNA and covalently attach to guanine residues

Interfere with the action of endonuclease enzymes on DNA and block transcription by inhibiting DNA polymerase in a sequence specific manner

Other cytotoxic agents used in the development of antibody-drug conjugates include:

  • Streptonigtin (anti CD30 and anti CD70)
  • Geldanamycin (HSP90 inhibitor)
  • Centanamycin (ML-970; indolecarboxamide);
  • SN38 is the active metabolite of irinotecan (an analog of Camptothecin, a topoisomerase I inhibitor)
