Actually, this mechanism is very interesting. Do you think it will work on bacterials?

- Y3 P$ B) u7 Z2 d' C, y抗病毒药物还是有几种的,只是比较少~~~。机制也不同,大多是从附着、脱壳、出胞膜等角度着手的。

Looks like that you guys have excellent background on medicines. I am a chemist working in a pharmaceutical company.

B.T.W., from your point of view, how to avoid or solve drug-resistance problem?

总的说来,病毒类药物主要是根据病毒的复制而针对性开发的,主要有以下几类:5 E; m% @! a# k! U U+ N7 C

抗药性问题: 8 \4 N4 f( L1 l. Z从个体来说,主要是不滥服抗病毒药物和抗生素,以免产生抗性。从整体说:这就和电脑的杀毒软件和电脑病毒一样,是在不断拮抗之中的。当然如果不对动物和人滥用抗生素,抗药性情况会更好些。
