Hycanthone

Cell experiment:

Appropriate quantities of Hycanthone (1 to 100 μg) in 10 mL maintenance medium are added to plastic flasks (75 cm2) containing approximately 3×107 LLC-MK2 cells in monolayer, which are then incubated at 35°C for 24 h. Maintenance medium is decanted, and 2 mL influenza virus is added onto cell monolayers and incubated at 35°C for 2 h. The multiplicity of infection is approximately 1.0. Inoculum is removed and 10 mL maintenance medium is added to each flask, which is then incubated at 35°C for 24 h. Supernatant fluid is decanted, centrifuged at 100,000 g for 1 h, dialyzed against HCI-KCI buffer (pH 2.0) at 4°C for 24 h, and then dialyzed against two changes of phosphate-buffered saline (pH 7.1) at 4°C for 24 h. Fluids are passed through filters to obtain sterile preparations. Samples are stored at -80°C until assayed for interferon activity[2].

Animal experiment:

Female outbred Swiss albino mice used as definitive hosts weigh 18 to 20 g at the time of infection. Hycanthone is administered at 0.01 mL/g body weight intramuscularly by splitting the dose into the two hind legs, so that each mouse receives 80 mg/kg body weight of the free base. Treatments are usually performed during the 8th week after infection[1].
