PSI-7409 tetrasodium 是一种 sofosbuvir (PSI-7977) 的 5'-三磷酸活性代谢物，能够抑制 HCV NS5B polymerases，对 GT 1b_Con1，GT 2a_JFH1，GT 3a 和 GT 4a NS5B 聚合酶的 IC₅₀ 值分别为 1.6，2.8，0.7 和 2.6 μM。

PSI-7409 tetrasodium is an active 5-triphosphate metabolite of sofosbuvir (PSI-7977), inhibiting HCV NS5B polymerases, with IC 50 s of 1.6, 2.8, 0.7 and 2.6 μM for GT 1b_Con1, GT 2a_JFH1, GT 3a, and GT 4a NS5B polymerases, respectively.

PSI-7409 tetrasodium is an active 5-triphosphate metabolite, inhibiting HCV NS5B polymerases, with IC50s of 1.6, 2.8, 0.7 and 2.6 μM for GT 1b_Con1, GT 2a_JFH1, GT 3a, and GT 4a NS5B polymerases, respectively. PSI-7409 also weakly inhibits human DNA polymerase α, with an IC50 of 550 μM, but shows no inhibition on DNA Pol β and γ. In clone A cells, the levels of PSI-7409 gradually increases to a maximum concentration of about 25 μM over a period of 48 h. PSI-7409 forms at a much faster rate in primary human hepatocytes, achieving a maximum intracellular concentration of ～100 μM at 4 h and remains at that concentration for 48 h. has not independently confirmed the accuracy of these methods. They are for reference only.
