A sequence of symmetrical and unsymmetricalurea derivatives 1–24 were synthesized and characterized by standard spectroscopic techniques. The synthesized analogues were tested for their in vitro H+/K+-ATPase and anti-inflammatory activities. The majority of the compounds showed outstanding activity, compared to that of omeprazole and indomethacin, usual standard drugs of antiulcer and anti-inflammatory
合成了一系列对称和不对称的尿素衍生物1-24,并通过标准光谱技术进行了表征。测试了合成的类似物的体外H + / K + -ATPase和抗炎活性。与分别为抗溃疡和抗炎药的常用标准药物奥美拉唑和消炎痛相比,大多数化合物均具有出色的活性。特别是,羟基,甲基和甲氧基衍生物13-24是最活跃的化合物,对苯环上的各种取代基具有明显的扩增作用,因此对胃溃疡的抑制有积极作用。化合物1-3和22-24 由于分子上存在吸电子基团(Cl和F),因此具有出色的抗炎活性。

A grease composition comprising at least one polymer having a mesogen structure in the principal chain or in the side chain(s) thereof, and at least one viscous agent is disclosed. A viscous agent which is a discotic compound having, in the molecule thereof, a discotic core and three or more side chain groups radially extended from said discotic core is also disclosed. The discotic core and/or said side chain groups has at least one tautomeric group therein, and at least one side chain group of said three or more side chains has, at the end portion thereof, a long chain group in which 20 or more atoms selected from the group consisting of oxygen, carbon, nitrogen, silicon and sulfur atoms are linked in a straight-chain-like manner or in a branched manner.
