Abstract

A novel class of antiinflammatory drugs, which are substituted derivatives of the fused tricyclic system 6-hydroxypyrimido [2, 1-flpurine-2, 4, 8 (lH, 3H, 9H)-trione (see, for instance, Table 111), is described. Synthetic procedures and structure determination with the assistance of X-ray crystallography are discussed. Semiempirical molecular orbital calculations are used to investigate the relative stability of the possible isomers and ...
