Dehydroaltenusin

Cancer-programmed cell death

Room temperature

Dehydroaltenusin is a small molecule selective inhibitor of eukaryotic DNA polymerase α, a type of antibiotic produced by a fungus with an IC50 value of 0.68 μM. The inhibitory mode of action of dehydroaltenusin against mammalian pol α activity is competitive with respect to the DNA template primer (Ki=0.23 μM) and non-competitive with respect to the 2'-deoxyribonucleoside 5'-triphosphate substrate (Ki=0.18 μM)[1]. Dehydroaltenusin arrests the cancer cell cycle at the S-phase and triggers apoptosis[1]. Dehydroaltenusin possesses anti-tumor activity against human adenocarcinoma tumor in vivo[1].
