structural features of Schiff bases of hydroxyaminoguanidines (SB-HAG) led to nine substituted salicylaldehyde Schiff bases of HAG (SSB-HAG) derivatives and three other SB-HAG derivatives. These new compounds were tested for the first time against infection by a coronavirus, mouse hepatitis virus (MHV). The most active compound, 2 [1-[(3'-allyl-2'-hydroxybenzylidene)amino]- 3-hydroxyguanidine], against the
羟基氨基胍(SB-HAG)的席夫碱的结构特征的进一步修改导致HAG衍生物(SSB-HAG)衍生物和其他三个SB-HAG衍生物的九个取代的水杨醛席夫碱。首次对这些新化合物进行了抗冠状病毒,小鼠肝炎病毒(MHV)感染的测试。最具活性的化合物2 [1-[((3'-烯丙基-2'-羟基亚苄基)氨基] -3-羟基胍]对MHV的生长比羟基胍的活性高约376倍,比HAG活性高约564倍比较TCID50值本身。从用这些化合物处理过的细胞释放的MHV的噬菌斑分析表明,SSB-HAG甲苯磺酸盐可能抑制病毒感染的细胞中病毒RNA的转录。对两个子集的定量构效关系(QSAR)分析表明,抑制活性与电子和亲脂性参数密切相关。根据对这些新化合物的抑制活性和QSAR分析,对甲苯磺酸SSB-HAG甲苯磺酸盐抗冠状病毒感染的抗病毒活性的结构要求非常严格。
