The present invention relates to the imidazole derivative of the following formula (I)
wherein R1 is hydrogen, optionally substituted alkyl and the like, R2 is hydrogen, optionally substituted alkyl and the like, R3is optionally substituted heteroaryl, R4 is optionally substituted cycloalkyl, optionally substituted phenyl and the like, provided that when R1 is hydrogen, and R2 and R4 are the same or different and each is phenyl or phenyl substituted by halogen atom, lower alkyl or lower alkoxy, R3 is benzothiazolyl or thiazolyl substituted by phenyl, the imidazole derivative of the following formula (XII)
wherein R6 is optionally substituted phenyl or optionally substituted heteroaryl and R7 is substituted phenyl, and pharmaceutically acceptable salts thereof. The compounds of the formulas (I) and (XII) and pharmaceutically acceptable salts thereof of the present invention inhibit IL-4 and IL-5 production by Th2 cells and are effective for the prophylaxis and treatment of allergic diseases such as atopic dermatitis, bronchial asthma, allergic rhinitis and the like.

showing the importance of steric bulk around the bicyclic ring system. The derived C7-carboxamidotetramates, but not C7-acyl systems, exhibited potent antibacterial activity against MRSA, with the most active compounds exhibiting well-defined physicochemical and structure–activity properties. This work clearly demonstrates that denselyfunctionalised tetramates are both readily available and may exhibit
