Albaspidin AA displays strong antibacterial activity against the vegetative form of P. larvae (MIC ranging from 0.168-220 uM). It may have in vitro nematocidal activity against L4 stage larvae.
Filixic acid ABA exhibits inhibitory effects on neuraminidase of influenza virus H5N1 with IC50 as 29.57 ± 2.48 μM, it may have anti-influenza virus activity.
Albaspidin-AP, -PP, -PB inhibit Fatty acid synthase (FAS) with IC50 values ranging from 23.1+/-1.4 to 71.7+/-3.9 microM, they could be considered to be a promising class of FAS inhibitors, and FAS is emerging as a potential therapeutic target to treat can
Ptaquiloside shows genotoxicity, it also has carcinogenic effects. Ptaquiloside has immunosuppressive effects, it reduces NK cell activities by enhancing metallothionein expression, which is prevented by selenium.
