The compound has an excellent anti-inflammatory activity, and other biological activity.

Pyridine derivatives

4-aryl pyrimidine compounds of general formula and salts thereof: wherein X is CH or N; R1 is hydrogen, halogen, C1-6 alkyl, C1-6 alkoxy, etc.; R2 is hydrogen or hydroxy; R3 is hydrogen, C1-6 alkyl, etc.; R4 is hydrogen, hydroxy, halogen, amino, etc.; R5 is hydroxy, amino, carboxy, etc.; R6 is hydrogen, carbamoyl, cyano, carboxy, C1-6 alkoxycarbonyl, etc. and R7 is amino or C1-6 alkanoylamino. The compounds (I) or the salts thereof have an excellent anti-inflammatory activity and the like.

4-6-diphenyl pyridine derivatives as antiinflammatory agents

This invention is to provide a process for producing 2-amino-4,6-disubstituted nicotinic acid ester analogs and salts thereof, comprising the reaction shown by the following scheme. The ester analogs can be prepared in one pot, and in good yield by using tertiary alkyl cyanoacetate. Furthermore, the method is useful for preparing derivatives of various analogs of the ester, e.g. alkyl substituted and aryl substituted analogs. 

Pyridine compounds of general formula:wherein &#x2014;Rrepresentsin which Ris hydrogen, Calkyl, halogen, hydroxy, Calkoxy, nitro, amino, Calkylsulfonylamino, Calkoxycarbonyl, Calkylamino, di (Calkyl)amino, Calkanoylamino, phenyl Calkylamino, phenylsulfonylamino, or &#x2014;O&#x2014;(CH)&#x2014;R; Rrepresents hydrogen or halogen; Rrepresents 1.2.3.6-tetrahydro-pyridine, or &#x2014;CRRRwherein Rrepresents H or Calkyl and Rand Rare joined to form a 5-8 membered saturated ring optionally containing up to three heteroatoms; Ris carbamoyl, CN, carboxyl, etc.; Ris amino, Calkylamino, di Calkylamino, etc. or salt thereof. The compound has an excellent anti-inflammatory activity, and other biological activity.

A compound of the formula (I)in which Ris &#x2014;OR, &#x2014;SR, &#x2014;SOR, &#x2014;SOR, &#x2014;NHR, or &#x2014;NRR, and R, R, and Rare as defined broadly in the text. Ris H, C-Calkyl, carbamoyl, or an ester group. Ris thienyl, pyridyl optionally substituted by halogen or C-Calkoxy; naphthyl optionally substituted by C-Calkoxy; dioxane fused phenyl; dioxacyclopentane fused phenyl; or optionally substituted phenyl. Y is CH or N. A process for preparing such compounds, pharmaceutical compositions containing such compounds, and a method of treating asthma using them are also disclosed and claimed.
