摘要:
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 selectivity of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently markered non-steroidal anti-inflammatory drugs (NSAIDs).
摘要:
The invention relates to compounds having activity to inhibit lipoxygenase enzyme activity, to pharmaceutical compositions comprising these compounds, and to a medical method of treating. More particularly, this invention concerns certain substituted arylalkynyl- and ((heteroaryl)alkynyl)-N-hydroxy-ureas which inhibit leukotriene biosynthesis, to pharmaceutical compositions of these compounds and to a method of inhibiting leukotriene biosynthesis.
摘要:
Compounds of the structure ##STR1## where p and q are zero or one, but cannot both be the same, M is a pharmaceutically acceptable cation or a metabolically cleavable group, B is a valence bond or a straight or branched alkylene group, R is alkyl, cycloalkyl or --NR.sup.1 R.sup.2, where R.sup.1 and R.sup.2 are hydrogen, alkyl, cycloalkyl or alkanoyl, and A is optionally substituted carbocyclic aryl, furyl, benzo[b]furyl, thienyl, or benzo[b]thienyl are potent inhibitors of lipoxygenase enzymes and thus inhibit the biosynthesis of leukotrienes. These compounds are useful in the treatment or amelioration of allergic and inflammatory disease states.
摘要:
Compounds having the structure ##STR1## or a pharmaceutically acceptable salt thereof have activity as inhibitors of cylooxygenase and 5-lipoxygenase, reduce the biosynthesis of leukotrienes B.sub.4, C.sub.4, D.sub.4, and E.sub.4 and cylooxygenase products such as prostaglandins and thromboxane and are useful in the treatment of inflammatory and allergic disease states.
