| Description | Calicheamicin (Calicheamicin γ1) is an antitumor antibiotic and is a DNA synthesis inhibitor. It also is a cytotoxic agent that causes double-strand DNA breaks. |
| In vitro | PF-06647263 (anti-EFNA4-ADC) is generated by conjugating hE22 lysine residues to the AcButDMH-N-Ac-calicheamicin-γ1 linker-payload, with an average drug-to-antibody ratio (DAR) of 4.6. PF-06647263 induces antigen- and concentration-dependent cytotoxicity, causing cell death after 96 hours of exposure (EC50: ~1 ng/mL) [1]. |
