Polyacrylic acid (PAA) and polymethacrylic acid (PMAA) were investigated for their antiviral properties in tissue culture. Compared to other related polyanions, as dextran sulfate, polystyrene sulfonate, polyvinyl sulfate, and polyphloroglucinol phosphate, PAA and PMAA were found to be significantly more antivirally active and less cytotoxic. PMAA added 24 hr prior to virus inoculation inhibited viral growth most efficiently but it was still effective when added 3 hr after infection. Neither a direct irreversible action on the virus nor inhibition of virus penetration into the cell could explain the antiviral activity of PMAA. PMAA inhibited the adsorption of the virus to the host cell and suppressed the one-cycle viral synthesis in tissue cultures inoculated with infectious RNA.
研究了聚丙烯酸(PAA)和聚甲基丙烯酸(PMAA)在组织培养中的抗病毒特性。与其他相关聚阴离子,如硫酸葡聚糖、聚苯乙烯磺酸盐、聚乙烯硫酸盐和聚间苯三酚磷酸酯相比,发现PAA和PMAA具有显著更高的抗病毒活性且细胞毒性更小。在病毒接种前24小时添加PMAA能最有效地抑制病毒生长,但在感染后3小时添加仍有效。PMAA对病毒既没有直接的不可逆作用,也没有抑制病毒进入细胞,这无法解释其抗病毒活性。PMAA抑制病毒吸附到宿主细胞上,并抑制接种感染性RNA的组织培养中的单周期病毒合成。
