Background:

Xanthopterin, 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 (XPT) causes renal growth and hypertrophy in rat[1].Xanthopterin inhibits RNA synthesis[4].


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



[1]. Xanthopterin (XPT), an unconjugated pteridine compound, affects cell growth and differentiation. When injected into rats, XPT has caused changes that have been interpreted as renal growth and hypertrophy. [2]. Lord JL, et al. Cytotoxicity of xanthopterin and isoxanthopterin in MCF-7 cells.
