Biological Activity

[Description]:

Xanthopterin hydrate, an unconjugated pteridine compound, is the main component of the yellow granule in the Oriental hornet bear wings, produces a characteristic excitation/emission maximum at 386/456 nm[2]. Xanthopterin hydrate(XPT) causes renal growth and hypertrophy in rat[1].Xanthopterin hydrate inhibits RNA synthesis[4].

[In Vitro]

Xanthopterin (7.8-250 mM; 24 hours) show a significant reduction in mitochondrial activity with respect to controls (IC50=109 mM)[2]. Cell Viability Assay[2] Cell Line: MCF-7 cells Concentration: 7.8 mM-250 mM Incubation Time: 24 hours Result: Resulted in a reduction in mitochondrial activity.
