Description
In Vitro
Rabdosin B (200 μM; 3-12 h) induces cell cycle retardation of the G2 phase and S phase in root meristematic cells. Rabdosin B shows a time- and dose-dependent increase in DNA damage[1].
Rabdosin B shows a biphasic, dose-dependent effect on root growth and a strong inhibitory effect on root hair development in lettuce seedlings (Lactuca sativa L.). Lower concentrations of Rabdosin B (20-80 μM) significantly promots root growth, but its higher levels at 120-200 μM, by contrast, has inhibitory effects. Additionally, all tested concentrations (10-40 μM) inhibits root hair development of seedlings in a dose-dependent manner[1].
Rabdosin B has cytotoxic against human tumour HepG2, GLC-82 and HL-60 cell lines with IC50 values of 8.95 μM, 4.47 μM and 10.22 μM, respectively[2].
Rabdosin B (6 μM, 9 μM, 12 μM, 15 μM; 24-48 hours) induces significant DNA damage to HepG2 cells in a time- and dose-dependent manner[2].

Genotoxicity/Mutagenicity Study
The bacterial reverse mutation assay detects point mutations that restore amino-acid prototrophy in auxotrophic Salmonella typhimurium or Escherichia coli tester strains; after exposure to a test article, mutagenic activity is read out as an increased number of revertant colonies on minimal agar compared with the vehicle control. The assay uses tester strains with different mutation targets so that base-substitution and frameshift mutagens can be detected, and testing is performed with and without exogenous mammalian metabolic activation because some chemicals require biotransformation to become mutagenic.
