In Vitro
Although still exceptionally potent, the iso-duocarmycin SA derivatives and natural product analogues exhibited a corresponding approximate 3-5-fold reduction in cytotoxic activity [L1210 IC(50) for (+)-iso-duocarmycin SA = 50 pM and for (+)-iso-yatakemycin = 15 pM] consistent with their placement on a parabolic relationship correlating activity with reactivity. The DNA alkylation selectivity of the resulting key natural product analogues was unaltered by the structure modification in spite of the minor-groove presentation of a potential H-bond donor.
In Vivo
Duocarmycin SA (DSA) concentrations as low as 0.001 nM significantly sensitized U-138 cells to proton irradiation. DSA demonstrates synergistic cytotoxicity against GBM cells treated with proton radiation in vitro, which may represent a novel therapeutic alternative for the treatment of GBM.
