    摘要:
    该发明描述了式I的吡啶并酮化合物,这些化合物是环氧合酶(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,与构成性异构体环氧合酶-1(COX-1)相对,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的选择性减少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。

    To synthesize 4-chloro-5-methoxy-2-(β-trifluoroethyl)-3(2H)-pyridazinone (4), the reactions of 4-chloro-5-methoxy-3(2H)-pyridazinone (5) with RCH2CF3 (R = I, TsO, MsO, TfO) in different solvents were studied. It was found that methyl group migration took place during this reaction. An oxonium salt 9 was suggested as the active intermediate for the formation of the byproduct 4-chloro-5-methoxy-2-me

    The present invention describes pyridazinone compounds of formula (I) 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 selectively of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently marketed non-steroidal anti-inflammatory drugs (NSAIDs).
    本发明描述了式(I)的吡啶酮化合物,它们是环氧合酶(COX)抑制剂,特别是选择性抑制剂环氧合酶-2(COX-2)。COX-2是与炎症有关的诱导型同工酶,而非构成型同工酶环氧合酶-1(COX-1),后者是许多组织(包括胃肠道和肾脏)中重要的“管家”酶。这些化合物对COX-2的选择性最小化了目前市场上非甾体类抗炎药(NSAIDs)所见的不良胃肠道和肾脏副作用。
