Xanthopterin
Based on 1 Customer Validation
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. Xanthopterin (XPT) causes renal growth and hypertrophy in rat. Xanthopterin inhibits RNA synthesis.
