Description: SG2057 is a pentyldioxy linked PBD dimer which binds sequence selectively in the minor groove of DNA forming DNA interstrand and intrastrand cross-linked adducts, and also mono-adducts depending on sequence. SG2057 has multilog differential in vitro cytotoxicity against a panel of human tumour cell lines with a mean GI(50) of 212 pM. The agent is highly efficient at producing DNA interstrand cross-links in cells which form rapidly and persist over a 48 h period. Significant antitumor activity was demonstrated in several human tumor xenograft models.
