The present invention describes pyridazione compounds having the formula (I), which are cyclooxygenase (COX) inhibitors The compounds are selective inhibitors of cyclooxygenase-2-(COX-2), which 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).
该发明描述了具有式(I)的吡啶化合物,这些化合物是环氧合酶(COX)抑制剂。这些化合物是环氧合酶-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,而不同于构成型同工酶环氧合酶-1(COX-1),后者是许多组织中重要的“基础”酶,包括胃肠道(GI)和肾脏。这些化合物对COX-2的选择性降低了目前市售的非甾体类抗炎药(NSAIDS)所见到的不良胃肠道和肾脏副作用。
