Abstract
The invention relates a group of compounds having formula (I) and their use as medicaments for non-steroidal analgesic analgesia, anti-arthritis, and protecting gastrointestinal tract mucous membrane. The invention also discloses the pharmaceutical compositions containing the compounds of formula (I), wherein R1, R2, R3 and X are defined in the specification.
Description
Technical field
The invention belongs to autoimmunization and regulate technical field of pharmaceuticals, in particular, the pharmaceutical composition and the purposes that the present invention relates to a kind of new compound and preparation method thereof and contain this compound.
Background technology
For a long time, NSAID (non-steroidal anti-inflammatory drug) such as Asprin, be widely used in treatments such as analgesic, analgesia and resisting rheumatoid disease, but because unsatisfactory curative effect and common gi tract and Toxicity of Kidney are restricted this class medicinal application, especially to such as suffering from disease such as rheumatic arthritis, the patient that need take medicine for a long time is more like this.These pharmacological actions of NSAID (non-steroidal anti-inflammatory drug) may to carry out the biosynthetic cyclooxygenase of prostaglandin(PG) relevant with blocking-up gi tract and renal tissue arachidonic acid.Suppressing cyclooxygenase is the main mechanism of most of NSAID (non-steroidal anti-inflammatory drug), is diseases such as prevention, treatment asthma and anaphylaxis and suppress the 5-lipoxygenase.Recent study shows that prostaglandin(PG) is not the factor that directly causes leucocyte chemotaxis, and belongs to the leukotriene B of arachidonic acid metabolite
4(LTB
4) be that a kind of intensive causes the material from cell chemotaxis.Arachidonic acid generates various leukotrienes under the catalysis of 5-lipoxygenase, cause acute and chronic inflammation.The cyclooxygenase-2 inhibitors class medicine that has now gone on the market does not suppress to produce the 5-lipoxygenase of various leukotrienes under effective inhibition cyclooxygenase-2 activity concentration, also can not block the generation of this metabolic pathway product.In fact because this type of medicine has suppressed arachidonic acid and also just might cause more substrate through the metabolism of cyclooxygenase approach,, cause the synthetic increase of various leukotrienes by the lipoxygenase pathway metabolism.Compound of the present invention is the common inhibitor of cyclooxygenase and 5-lipoxygenase, promptly keeps the curative effect of cyclooxygenase-2 inhibitors, has avoided again causing various untoward reactions by leukotriene.
Summary of the invention
It is the new cyclooxygenase and the common inhibitor of 5-lipoxygenase that one object of the present invention has been to provide a kind of nonsteroidal new compound.
