psychostimulant activity of sydnocarb is linked with the presence of a phenylcarbamoyl residue on the exocyclic nitrogen atom of the sydnonimine. Further introduction of chlorine atoms or a trifluoromethyl group into various positions of the phenyl ring of the carbamoyl residue leads to a strengthening of central stimulant activity, however, toxicity was also increased by this [2].
先前表明 [1] sydnocarb 的精神兴奋剂活性与 sydnonimine 的环外氮原子上苯基
氨基甲酰基残基的存在有关。将
氯原子或三
氟甲基进一步引入
氨基甲酰基残基苯环的不同位置导致中枢兴奋剂活性增强,但毒性也因此增加[2]。
