Two Trichothecene Mycotoxins from Myrothecium roridum Induce Apoptosis of HepG-2 Cells via Caspase Activation and Disruption of Mitochondrial Membrane Potential.
Trichothecene mycotoxins are a type of sesquiterpenoid produced by various kinds of plantpathogenic fungi. In this study, two trichothecene toxins, namely, a novel cytotoxic epiroridin acid and a known trichothecene, mytoxin B, were isolated from the endophytic fungus Myrothecium roridum derived from the medicinal plant Pogostemon cablin. The two trichothecene mytoxins were confirmed to induce ...
متن کاملIsolation and characterization of two verrucarins from Myrothecium roridum.
In the course of a screening for compounds inhibiting the growth of two human breast cancer cells lines, two highly cytotoxic compounds were isolated from fermentations of Myrothecium roridum. The elucidation of their structures revealed that they are macrocyclic trichothecenes of the verrucarin type, 16-hydroxyverrucarin A (1), reported here as a natural product for the first time, and verruca...
متن کاملEconazole Nitrate Induces Apoptosis in MCF-7 Cells via Mitochondrial and Caspase Pathways
Econazole nitrate (EN), a synthetic compound, is now in use as a routine antifungal drug. EN was shown to have antitumor effect, the tumor cell killing mechanisms, however, remain unclear. In this research, the apoptosis-inducing effect of EN on MCF-7 cells was investigated. The results showed that EN inhibited the proliferation of MCF-7 cells in a time- and dose-dependent manner by MTT method ...

متن کاملPhytotoxicity and mammalian cytotoxicity of macrocyclic trichothecene mycotoxins from Myrothecium verrucaria.
Macrocyclic trichothecene toxins produced by Myrothecium verrucaria (a phytopathogen of interest in biological weed control) and the non-trichothecene toxin atranone B from Stachybotiys atra were tested for phytotoxicity in duckweed (Lemna pausicostata L.) plantlet cultures and kudzu (Pueraria lobata L.) leaf disc assays, and for mammalian cytotoxicity in four cultured cell lines. Roridin E and...
