A series of alkylazulene-1-sodium sulfonate derivatives which has an isopropyl group at 6-position were synthesized, and their anti-ulcer activities were examined in Shay pylorus-ligated rats. The values of lipophilicity (log P) as a parameter of these new azulene derivatives were also examined in reference to the structure-activity relationship. The optimum value of log P, which showed maximal anti-ulcer activity, was about -0.46. Among the derivatives of azulene examined, 3-ethyl-6-isopropylazulene-1-sodium sulfonate (compound IXb : KT1-785) exhibited the most potent inhibitory action against Shay ulcer, and its anti-peptic activity was similar to that of 3-ethyl-7-isopropylazulene-1-sodium sulfonate (KT1-32). It also had more activity than guaiazulene sodium sulfonate (GAS). Furthermore, KT1-785 was extremely stable under heating as compared to GAS.
研究人员合成了一系列烷基氮杂环烯-1-磺酸钠衍生物,这些衍生物在 6 位上有一个异丙基,并在 Shay 幽门结扎大鼠体内检测了它们的抗溃疡活性。此外,还参照结构-活性关系研究了这些新的薁衍生物的亲脂性(log P)参数值。显示最大抗溃疡活性的最佳对数值约为-0.46。在所研究的薁衍生物中,3-乙基-6-异丙基薁-1-磺酸钠(化合物 IXb:KT1-785)对夏伊溃疡的抑制作用最强,其抗消化活性与 3-乙基-7-异丙基薁-1-磺酸钠(KT1-32)相似。它的活性也高于瓜亚磺酸钠(GAS)。此外,与 GAS 相比,KT1-785 在加热条件下极为稳定。
