How to use
In Vitro:
5,6-Dihydroxyindole (1, 10, 20, 50, 100 μM; for 4 hours) dose-dependently decreases OD492 values. Pretreatment of Sf9 cells with 1.0 mM 5,6-Dihydroxyindole for 4 hours results in 97% mortality, and LC50 values of 20.3 μM in buffer and 131.8 μM in a culture medium. Preincubation of a baculovirus stock with 1.25 mM 5,6-Dihydroxyindole for 3 hours near fully disables recombinant protein production. The LC50 for lambda bacteriophage and eggs of the wasp Microplitis demolitor are 5.6 and 111.0 μM, respectively. 5,6-Dihydroxyindole and its spontaneous oxidation products are also active against viruses and parasitic wasps.
