title: 6-Dimethylamino 1H-pyrazolo[3,4-d]pyrimidine derivatives as new inhibitors of inflammatory mediators in intact cells.
abstract: The synthesis of 6-dimethylamino 1H-pyrazolo[3,4-d]pyrimidines substituted at positions 1 and 4, and their effects on murine macrophage and human neutrophil functions are described. Several compounds and especially 4b-6b are potent inhibitors of PGE(2) generation in murine macrophages. This action is related to a direct effect on COX-2 activity without affecting the enzyme expression. Some of these compounds also inhibited COX-1 and COX-2 in human monocytes and 4b showed selectivity for COX-2 inhibition.
