Tesirine (SG3249) is an antibody-drug conjugate (ADC) pyrrolobenzodiazepine (PBD) dimer payload. Tesirine combines potent antitumor activity with desirable physicochemical properties such as favorable hydrophobicity and improved conjugation characteristics. SG3199 ( HY-101161 ) is the released warhead component of the ADC payload Tesirine. SG3199 retains picomolar activity in a panel of cancer cell lines. PBD dimers are highly efficient DNA minor groove cross-linking agents with potent cytotoxicity
In Vitro
SG3199 (HY-101161) is the released warhead component of the ADC payload Tesirine. SG3199 inhibits K562, NCIN87, BT474, and SKBR3 cancer cells with IC 50 s of 150 pM, 20 pM, 1 nM and 320 pM. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
