A group of 4H-1,2,4-triazole-derived thioureas was efficiently prepared and evaluated for antibacterial,
antifungal and antiviral activities.The chemical identity of all derivatives was established on the
basis of spectral methods. The molecular structures of 10 and 21 were determined by an X-ray crystallography.
Compounds with phenyl (1), 3,4-dichlorophenyl (2) and p-methoxyphenyl (3) substituents were the
most promising against fungi species. The derivative 12 has proved to be significantly active against CVB-5.
The CNS-activity of five new 4H-1,2,4-triazolo-thiourea derivatives 2, 10, 12, 18 and 21 was investigated. The results
proved that activity of all tested thiourea compounds may be connected with the serotonergic system. Derivatives 2, 10,
12, 18 acted as inhibitors of the head twitch responses (HTR).The biological activity of 21 was also linked with the endogenous
opioid system. The derivative 18 diminished the spontaneous mobility and 10 reduced the amphetamineinduced
activity of laboratory animals.
一批4H-1,2,4-三唑衍生物硫脲被高效制备并评估其抗菌、抗真菌和抗病毒活性。所有衍生物的化学身份基于光谱方法确立。分子结构10和21通过X射线晶体学确定。具有苯基(1)、3,4-二氯苯基(2)和p-甲氧基苯基(3)取代基的化合物对真菌种类最为有效。衍生物12对CVB-5显示出显著活性。研究了五个新的4H-1,2,4-三唑硫脲衍生物2、10、12、18和21的中枢神经系统活性。结果证明所有测试的硫脲化合物的活性可能与血清素系统有关。衍生物2、10、12、18作为头部抽动反应(HTR)的抑制剂。21的生物活性也与内源性阿片系统相关。衍生物18降低了自发活动性,10减少了实验室动物的安非他命诱导活动。
