, p. 1053 - 1059 (2007/10/02)
A convenient synthesis is described for pyrazoloquinazolin-9-one (4), an internally expanded benzolog of the biologically relevant pyrazolopyrimidines (2).
Synthesis of prox-Benzoisoallopurinol
Foster, Robert H.,Leonard, Nelson J.
, p. 3072 - 3077 (2007/10/02)
Pyrazoloquinazolin-9-one (prox-benzoisoallopurinol, 1), an extented analogue of 7-hydroxypyrazolopyrimidine (isoallopurinol, 2) and a potential dimensional probe for substrates of xanthine oxidase, has been synthesized by two independent routes.The title compound, prepared by elaboration of either a suitably substituted indazole or a quinazolinone, was found to be an active substrate for and an alternative-substrate inhibitor of xanthine oxidase.The product of enzymatic oxidation of prox-benzoisoallopurinol has been identified as the corresponding prox-benzoisoalloxanthine.
