The present invention describes pyridazinone compounds of formula I
1
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).
本发明描述了公式I1的吡啶并咪唑酮化合物,它们是环氧合酶(COX)抑制剂,特别是选择性地抑制环氧合酶-2(COX-2)。 COX-2是与炎症相关的可诱导异构体,与包括胃肠道和肾脏在内的许多组织中重要的“家务”酶环氧合酶-1(COX-1)相对。这些化合物对COX-2的选择性最小化了目前市场上非甾体抗炎药(NSAIDs)所见的不良胃肠和肾脏副作用。
