The present invention is directed to a compound represented by formula (1): (wherein Rrepresents an alkyl group which may have a substituent or an alkenyl group which may have a substituent; and each of Rand Rrepresents a hydrogen atom, an alkyl group, a hydroxyalkyl group, a dihydroxyalkyl group, or an alkynyl group, or Rand Rform, together with the nitrogen atom adjacent thereto, a nitrogen-containing saturated heterocyclic group which may have a substituent) and a drug composition containing the compound. The compound exhibits tumor necrosis factor (TNF-&#x3b1;) production inhibitory effect and improved absorption upon oral administration.

Benzofuran derivative

A phenylpyridazine derivative represented by the formula (1): Wherein, R1, R2, R3, X, Y, Z and n have the same meaning as defined in the specification; or a salt thereof, or a medicine containing the compound. The present invention provides water-soluble phenylpyridazine derivatives and medicines containing them, which have excellent inhibitory activity against interleukin-&#x3b2; production, high water solubility and high oral absorbability.

Water-soluble phenylpyridazine derivative and medicine containing the same

Compounds having the formula (1): wherein Rrepresents an alkyl or alkenyl group, Rand Reach independently represent a hydrogen atom or an alkyl, hydroxyalkyl, dihydroxyalkyl or alkynyl group, or Rand Rmay be fused together with the adjacent nitrogen atom to form a substituted or unsubstituted, nitrogen-containing, saturated heterocyclic group, X, Y and Z each independently represent a hydrogen atom, an alkyl group, a halogen atom or the like, and n stands for an integer of from 1 to 5; and also to medicinal compositions containing them. These compounds have inhibitory activity against IL-1&#x3b2; production, high water solubility and good oral absorbability.
