Many derivatives of sodium alkylazulene sulfonates were newly synthesized and their antiulcer activites were examined in Shay pylorus-ligated rats. The values of lipophilicity (log P), a physicochemical parameter, of these new azulene derivatives were also examined in order to study the structure-activity relationship. The optimum value of log P which gave maximum anti-ulcer activity was about -1.0. Among the derivatives of azulene examined, 3-ethyl-7-isopropylazulene-1-sulfonic acid sodium salt (KT1-32) exhibited an extremely potent inhibitory action against Shay ulcer, and its antipeptic activity was more potent than than of guaiazulene sodium sulfonate (GAS). Furthermore, KT1-32 was extremely stable on heating as compared to GAS.
多种新合成的钠代烷基吖啶磺酸盐衍生物在沙伊幽门结扎大鼠中进行了其抗溃疡活性的检测。此外,还研究了这些新吖啶衍生物的亲脂性(log P)这一物理化学参数,以探讨结构-活性关系。log P的最佳值,即提供最大抗溃疡活性的值,大约为-1.0。在检测的吖啶衍生物中,3-乙基-7-异丙基吖啶-1-磺酸钠盐(KT1-32)对沙伊溃疡显示出极其强大的抑制作用,其抗胃酸活性比愈创木基吖啶磺酸钠(GAS)更强。此外,与GAS相比,KT1-32在加热过程中极为稳定。
