Notes: Isoxanthopterin is a natural intermediate in the pteridine pathway, which has roles in pigmentation and cell division.{29527} It can be produced naturally from 7-oxobiopterin or in vitro by the oxidation of pterin by xanthine oxidase.{29527,29524} Isoxanthopterin is a guanine analog that interferes with RNA and DNA synthesis and can inhibit cell proliferation.{29523,29526} Methylated derivatives of isoxanthopterin are fluorescent guanine analogs that are used to study DNA structure.{29523,29525}
