unrelated DNA and RNA viruses. Compound 24 represents a new class of selective influenza A virus inhibitors acting during the virus entry process, as evidenced by our findings in a time-of-addition assay. Molecular descriptors and in silico prediction of ADMET properties of the active compounds were calculated. According to in silico ADMET and drug similarity studies, active compounds have been estimated to
在之前的研究中,我们发现了一类具有抗病毒活性的 1,3,4-噻二唑衍生物。N -3-(甲基硫烷基)-1-[5-(苯基氨基)-1,3,4-噻二唑-2-基]丙基}苯甲酰胺成为设计新型甲型流感病毒抑制剂的相关先导化合物。在本研究中,我们通过对一系列结构类似物进行化学合成和抗病毒评估来详细阐述这一初步线索。在这项研究中,通过环化相应的氨基硫脲作为合成前体,合成了 13 种新型 1,3,4-噻二唑衍生物。通过色谱和光谱数据确认合成化合物的结构和纯度。四升-基于蛋氨酸的 1,3,4-噻二唑衍生物显示出抗甲型流感病毒的活性,两种最好的化合物是24带有 5-(4-氯苯基氨基)-1,3,4-噻二唑部分,30带有 5-( benzoylamino)-1,3,4-thiadiazole structure [antiviral EC 50针对流感 A/H3N2 病毒:分别为 4.8 和 7.4 µM]。1,3
