Biological Activity
Questin exhibits antibacterial activity against V. harveyi, V. anguillarum, V. cholerae, and V. parahemolyticus with MIC values of 31.25 µg/mL, 62.5 µg/mL, 62.5 µg/mL, and 125 µg/mL, respectively[1].
Questin (48 h) strongly inhibits the growth of human colon cancer cells (SW620), with a GI50 value of 0.9 mg/mL[2].
Questin (50-100 μM; 24 h) shows certain toxicity to the human A549 lung cell line and reduces cell viability[3].
Questin displays a moderate level of selective antiprotozoal activity against the animal protozoan pathogen Tritrichomonas foetus, with a MIC of 12.5 µg/mL[5].
