Abstract
Oxazole derivatives of the formula (I) ##STR1## wherein one of R and R.sub.1 is a methylsulfonylphenyl, an aminosulfonyl-phenyl or an alkylaminosulfonylphenyl, and the other is a cycloalkyl having 5 to 7 carbon atoms which is optionally substituted by lower alkyl, a thienyl optionally substituted by lower alkyl or halogen atom or a furanyl optionally substituted by lower alkyl or halogen atom, and R.sub.2 is a lower alkyl, and pharmaceutically acceptable salts thereof. The oxazole derivatives and pharmaceutically acceptable salts thereof have superior antipyretic action, analgesic action, anti-inflammatory action, and particularly, selective inhibitory action on cyclooxygenase-2 (COX-2), and are expected to be useful as an antipyretic agent, an analgesic agent and an anti-inflammatory agent with less side-effects such as disorders in the digestive tract.
