(24R)-Cycloart-25-ene-3beta,24-diol may be an anti-tumor promoter, it exhibits inhibitory effects on both Epstein-Barr virus early antigen (EBV-EA) and (+/-)-(E)-methtyl-2-[(E)-hydroxyimino]-5-nitro-6-methoxy-3- hexemide (NOR 1) activation.
11-Oxomogroside IIa is a cucurbitane glycoside extracted from the fruits of Siraitia grosVenorii. It has inhibitory effects against the EBV-EA activation induced by TPA, shows weak inhibitory effects on activation of NOR 1, a nitric oxide (NO) donor.
Mogroside III-A2 exhibits inhibitory effects with IC50 values of 346-400 mol ratio/32 pmol TPA. and shows weak inhibitory effects on activation of (+/-)-(E)-methyl-2-[(E)-hydroxyimino]-5-nitro-6-methoxy-3-hexemide (NOR 1), a nitric oxide (NO) donor.
