Description
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). Dehydroaltenusin arrests the cancer cell cycle at the S-phase and triggers apoptosis. Dehydroaltenusin possesses anti-tumor activity against human adenocarcinoma tumor in vivo.

How to use
In Vitro:
Dehydroaltenusin (38.0-44.4 μM; 24 hours) inhibits cell growth in a dose-dependent manner and the LD50 values varies from 38.0 to 44.4 μM. Dehydroaltenusin (38.0 μM; 6 hours) inhibits cell growth by blocking the S-phase of DNA replication. Dehydroaltenusin (75.0 μM; 24 hours) has a strong apoptotic effect on human cancer cells, DNA ladders can be detected after 12 h of incubation with dehydroaltenusin.
In Vivo:
Dehydroaltenusin (injection; 20 mg/kg; 2-day intervals; 12-39 days) shows suppressed tumor growth from 21 days.
