The preparation of 6- and 7-(pX-phenyl)-4(3H)-pteridinones (X = H, CH3, OCH3) is described.The oxidation of these compounds by (immobilized) Arthrobacter M-4 cells containing xanthine oxidase has been studied.The oxidation monitored by uv spectroscopy usually goes fast, except for 7-(pX-phenyl)-4(3H)-pteridinones (X = CH3, OCH3), which are slowly oxidized.With bacterial cells immobilized in gelatine crosslinked with glutaraldehyde small laboratory-scale oxidations were carried out.Based on spectral data the products of the oxidation reactions are 6- and 7-aryllumazines.

Reaction of 7-phenyl, 7-p-methoxyphenyl, 7-t-butyl- and 6,7-diphenylpteridine with ethylamine and t-butylamine in the presence of potassium permanganate leads to the introduction of the ethylamino or t-butylamino group at C-4 in the above-mentioned pterid

7-Phenyl, 7-(p-methoxyphenyl)-, 7-methyl-, 7-t-butyl-, 6,7-diphenyl-, 6,7-dimethyl- and 2-phenylpteridine are converted in good yields into their respective 4-amino compounds, when they are dissolved in liquid ammonia (-40 deg) and potassium permanganate
