摘要

几种抗病毒的无环核苷酸类似物可激活细胞因子基因的表达,如巨噬细胞中的tnf - α、IL-10和脾细胞中的ifn - γ。这是ifn - γ产生的一氧化氮大量增加的潜在机制。更亲脂性的前药,双- pom - pmea和双- poc - pmpa,对巨噬细胞具有杀细胞作用,从而抑制一氧化氮的形成。

Stimulation of cytokine and nitric oxide production by acyclic nucleoside phosphonates.

Several antiviral acyclic nucleotide analogues activate expression of genes for cytokines, such as TNF-alpha, IL-10 in macrophages and IFN-gamma in splenocytes. This is an underlying mechanism for substantially enhanced production of nitric oxide generated by IFN-gamma. More lipophilic prodrugs, bis-POM-PMEA and bis-POC-PMPA, are cytocidal for macrophages and thus inhibit nitric oxide formation.
