Duocarmycin SA is an orally active antitumor antibiotic with an IC50 of 10 pM. Duocarmycin SA is an extremely potent cytotoxic agent capable of inducing a sequence-selective alkylation of duplex DNA. Duocarmycin SA demonstrates synergistic cytotoxicity against glioblastoma multiforme (GBM) cells treated with proton radiation in vitro.
Duocarmycin SA (DSA) (0.1-1 nM
72 hours) inhibits U-138 cell viability in a dose-dependent manner and activates apoptotic and necrotic pathways[2]. Duocarmycin SA (0.1 nM
72 hours) sensitizes human glioma cells to proton irradiation[2].
Duocarmycin SA (0.143 mg/kg, i.p., single dose) shows antitumor activity in murine lymphocytic leukemia P388 transplanted in CDF1 mice and shows a significant 30% increase in life span[3].
