交替 苯乙烯-马来酸共聚物 (alt-PSMA)不同于其他 聚阴离子抗病毒剂, alt-PSMA的负电荷 由羧酸基团提供, 硫酸盐或磺酸盐部分。我们 假设alt-PSMA 会对人类产生 免疫缺陷病毒1型(HIV-1) 其他聚阴离子,如相关的 聚苯乙烯磺酸钠化合物 (PSS)。 在使用细胞系和原代 免疫细胞,alt-PSMA是 其特征在于细胞毒性低, 抑制HIV-1 BaL和IIIB感染, 以及亚型A、B和 C. 在作用机制测定中,其中每种 将化合物加入细胞中, 在HIV-1感染前移除 (“洗脱”测定), alt-PSMA未引起增强 感染,而PSS洗脱增加 感染率比控制水平高70%这些 研究证明 alt-PSMA是有效的HIV-1 抑制剂具有保证进一步 调查
An alternating copolymer of styrene and maleic acid (alt-PSMA) differs from other polyanionic antiviral agents in that the negative charges of alt-PSMA are provided by carboxylic acid groups instead of sulfate or sulfonate moieties. We hypothesized that alt-PSMA would have activity against human immunodeficiency virus type 1 (HIV-1) comparable to other polyanions, such as the related compound, poly(sodium 4-styrene sulfonate) (PSS). In assays using cell lines and primary immune cells, alt-PSMA was characterized by low cytotoxicity and effective inhibition of infection by HIV-1 BaL and IIIB as well as clinical isolates of subtypes A, B, and C. In mechanism of action assays, in which each compound was added to cells and subsequently removed prior to HIV-1 infection (“washout” assay), alt-PSMA caused no enhancement of infection, while PSS washout increased infection 70% above control levels. These studies demonstrate that alt-PSMA is an effective HIV-1 inhibitor with properties that warrant further investigation.
