For the purpose to examine as to their antiviral activities, 2-acylaminoacetamidine (II) and 3-acylaminopropionamidine hydrochlorides (III) were synthesized from the corresponding nitriles via ethyl imidates. The difference of the reactivity between ethyl 2-acylaminoacetimidates and ethyl 3-acylaminopropionimidates on the course of amidination were postulated. Iminoesterification of dinitrile, (p-cyano) benzamidopropionitrile (XVIII), was discussed by referring the infrared spectrum of a corresponding monocyanomonoester, ethyl p-(N-cyanoethylcarbamoyl) benzoate (XXI). Among the compounds obtained hereof, 3-(p-methyl) benzamidopropionamidine hydrochloride was found to have an inhibitory effect on influenza virus in mice and in membrane culture.
为了检测它们的抗病毒活性,通过相应的腈类经由乙基咪唑合成2-酰氨基乙脒(II)和3-酰氨基丙脒盐酸盐(III)。假设了乙基2-酰氨基乙咪唑和乙基3-酰氨基丙咪唑在酰胺化过程中的反应活性差异。通过参考相应的单氰单酯(ethyl p-(N-cyanoethylcarbamoyl) benzoate)(XXI)的红外光谱,讨论了二氰(对-氰基)苯甲酰胺丙腈(XVIII)的亚胺酯化。其中,3-(对-甲基)苯甲酰胺丙脒盐酸盐被发现对小鼠和膜培养中的流感病毒具有抑制作用。
