less susceptible. 3-[3-(4-Chlorophenyl)propyl]chroman (9c) was selected for preliminary mechanism of action studies due to its potent activity against both serotypes (IC50 of 0.48μM and 1.36μM towards HRV1B and 14, respectively) coupled with high selectivity (SI=206.18 and 73.26, respectively). Results of time of addition/removal studies suggest that 9c, similarly to related derivatives, behaves as a capsid
在我们研究抗鼻炎病毒色烯和苯并二氢吡喃衍生物的构效关系后,我们设计并合成了两个系列的新的3-苯基烷基-2H-色烯和-苯并二氢吡喃,在两个循环之间带有不同大小的脂肪族连接链。在HeLa细胞培养物中评估了新化合物对人鼻病毒(HRV)血清型1B和14感染的细胞毒性和抗病毒活性。大多数测试化合物以微摩尔或亚微摩尔浓度干扰HRV1B的繁殖,而HRV14较不敏感。选择3- [3-(4-氯苯基)丙基]苯并二氢吡喃(9c)是因为它对两种血清型均具有有效的活性(对HRV1B和14的IC50分别为0.48μM和1.36μM),并具有较高的抗药性,因此被选作初步的作用机理研究。选择性(分别为SI = 206.18和73.26)。
