Oxazolo[5,4-d]pyrimidines can be considered as 9-oxa-purine analogs of naturally occurring nucleic acid bases. Interest in this ring system has increased due to recent reports of biologically active derivatives. In particular, 5-aminooxazolo[5,4-d]pyrimidine-7(6H)-ones (9-oxa-guanines) have been shown to inhibit ricin. The...

Expert Opin Drug Discov. 2007 Sep;2(9):1161-83. doi: 10.1517/17460441.2.9.1161.

Naturally occurring methyl xanthines, especially caffeine and theophylline, have been widely investigated for their pharmacological properties as cognition enhancers, bronchodilator agents and mild diuretics. The xanthine core (3,7-dihydro-1H-purine-2,6-dione) has been largely manipulated in the search for selective ligands for...
