  4-(4-Cycloalkyl/aryl-oxazol-5-yl)benzenesulfonamides as Selective Cyclooxygenase-2 Inhibitors:  Enhancement of the Selectivity by Introduction of a Fluorine Atom and Identification of a Potent, Highly Selective, and Orally Active COX-2 Inhibitor JTE-522

  摘要：

  A series of 4-(4-cycloalkyl/aryl-oxazol-5-yl)benzenesulfonamide derivatives were synthesized and evaluated for their abilities to inhibit cyclooxygenase-2 (COX-2) and cyclooxygenase-1 (COX-1) enzymes. In this series, substituent effects at the ortho position to the sulfonamide group on the phenyl ring were examined. Most substituents reduced or lost both COX-2 and COX-1 activities. In contrast, introduction of a fluorine atom preserved COX-2 potency and notably increased COX-1/COX-2 selectivity. This work led to the identification of a potent, highly selective, and orally active COX-2 inhibitor JTE-522 [9d, 4-(4-cyclohexyl-2-methyloxazol-5-yl)2-fluorobenzenesulfonamide], which is currently in phase II clinical trials for the treatment of rheumatoid arthritis, osteoarthritis, and acute pain.

  Oxazole derivatives of the formula (I) wherein one of R and R1 is a methylsulfonylphenyl, an aminosulfonylphenyl 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 R2 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.

  式（I）的噁唑衍生物 其中 R 和 R1 中的一个是甲磺酰基苯基、氨磺酰基苯基或烷基氨磺酰基苯基，另一个是具有 5 至 7 个碳原子的环烷基，该环烷基可选择被低级烷基、可选择被低级烷基或卤素原子取代的噻吩基或可选择被低级烷基或卤素原子取代的呋喃基取代，R2 是低级烷基，以及它们的药学上可接受的盐。噁唑衍生物及其药学上可接受的盐类具有优异的解热作用、镇痛作用和抗炎作用，特别是对环氧化酶-2（COX-2）具有选择性抑制作用，有望用作解热剂、镇痛剂和抗炎剂，且副作用较小，如消化道功能紊乱。
