The present invention describes pyridazinone compounds which are cyclooxygenase (COX) inhibitors, and in particular, are selective inhibitors of cyclooxygenase-2 (COX-2). COX-2 is the inducible isoform associated with inflammation, as opposed to the constitutive isoform, cyclooxygenase-1 (COX-1) which is an important “housekeeping” enzyme in many tissues, including the gastrointestinal (GI) tract and the kidneys. The selectivity of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently marketed non-steroidal anti inflammatory drugs (NSAIDs).
本发明描述的
哒嗪酮化合物是环氧化酶(COX)
抑制剂,尤其是环氧化酶-2(COX-2)的选择性
抑制剂。COX-2 是与炎症相关的诱导型同工酶,而环氧合酶-1(COX-1)是组成型同工酶,是许多组织(包括胃肠道和肾脏)中重要的 "管家 "酶。这些化合物对 COX-2 的选择性最大程度地减少了目前市场上销售的非甾体抗炎药(N
SAIDs)对胃肠道和肾脏的副作用。
