Antivirální účinnost
Suspenze HeLa-buněk (6x10^) se smíchala se Rhinoviry HGP (3x10^ jednotek tvořících destičky, PFU) a nanesla na mikrozkušební desku, která obsahovala zkoušené sloučeniny ve stoupajícím zředění. Buňky se potom kultivovaly v Eglově roztoku minimální výživy, který obsahoval 2 % telecího séra, 1 % tryptosefosfátové polévky, 100 /Ug/ml streptomycinu a 20 jednotek/ml penicilinu G. Po 2 dnech kultivace při 33 °C se potom mikroskopicky pozoroval virální cytopathogenický účinek a cytotoxicita. Antivirální účinnost (I zkoušených sloučenin je taková koncentrace, při které je cytopathogenický účinek zbrzděn o 50 % proti kontrolní kultuře. Cytotoxicita je dána jako minimální koncentrace, při které byly pozorovány toxické symptomy (cytotoxická dávka).
Výsledky jsou uvedeny v tabulce 1 a ukazují, že sloučeniny podle vynálezu projevují anti-rhinovirovou aktivitu při koncentracích, které byly 10 až 10 000 krát nižší než cytotoxické dávky.
