chloride to yield, following the usual process, the oxamic acid derivatives. Most of the new compounds exhibited, by intraperitoneal route in rats, a very potent antianaphylactic activity on PCA response, higher than that of the reference compound disodium cromoglycate (DSCG). The new derivatives, in contrast with DSCG, were effective on PCA even by oral route. The most interesting derivative of the new series
合成了一系列N-(4-异恶唑基噻唑-2-基)草酰胺酸衍生物,并在大鼠被动皮肤过敏反应(PCA)模型上进行了测试,以验证其潜在的抗过敏活性。通过合适的溴乙酰基异恶唑与硫脲的反应得到相应的氨基噻唑,然后与草酸单酯氯化物缩合,按照常规方法制得草酰胺酸衍生物,从而制备这些化合物。大多数新化合物通过大鼠腹膜内途径表现出对PCA反应的非常强的抗过敏活性,高于参考化合物色甘酸二钠(DSCG)。与DSCG相比,新衍生物甚至通过口服途径对PCA也有效。
