| | XANTHOPTERIN Usage And Synthesis |
| Uses | 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]. | | Synthesis Reference(s) | Journal of the American Chemical Society, 95, p. 4455, 1973 DOI: 10.1021/ja00794a071 | | References | [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. DOI:10.1159/000188363
