PS1097
PS1097 is a broad-spectrum antiviral inhibitor with a BVDV RdRp IC50 of 0.64 μM. PS1097 selectively reduces RTN3 protein levels, causes partial RTN3 mRNA reduction, and leaves other endoplasmic reticulum-resident proteins unaffected. PS1097 inhibits replication of Zika virus and multiple viruses that use the endoplasmic reticulum as a replication hub. PS1097 inhibits BVDV RdRp enzymatic activity and exerts activity against Bovine Viral Diarrhea Virus. PS1097 can be used for the research of zika virus infection, usutu virus infection, west nile virus infection, COVID-19, coxsackie b virus 5 infection, chikungunya virus infection, vaccinia virus infection.

PS1097 (1.7-100 μM; 48 h) potently inhibits ZIKV Brazil/2016/INMI1 replication in Huh-7 cells with an EC50 of 0.69 μM and a high Selectivity Index of 331.7[1].
PS1097 (100 μM starting serial dilutions; 48 h most assays) exhibits broad-spectrum antiviral activity against multiple RNA and DNA viruses that rely on endoplasmic reticulum remodeling for replication, with EC50 values ranging from 0.1 to 5.51 μM across susceptible virus-cell line pairs, and high Selectivity Indices in most systems[1].
PS1097 (0.6-6 μM; 48 h) dose-dependently inhibits ZIKV NS5 protein synthesis in Huh-7 and Vero E6 cells, with maximal inhibition observed at 6 μM[1].
PS1097 (6 μM; 48 h) potently and selectively downregulates reticulon 3 protein levels in Huh-7 cells, with a partial reduction in corresponding reticulon 3 mRNA levels[1].
PS1097 (1.7-100 μM; 48 h) potently inhibits ZIKVBr replication in Huh-7 cells with an EC50 of 0.69 μM and a high SI of 331.7, indicating strong antiviral activity with low cytotoxicity[2].
PS1097 (0.6-6 μM; 48 h) dose-dependently inhibits ZIKVBr protein synthesis in Huh-7 and Vero E6 cells, leading to reduced viral yield[2].
PS1097 (6 μM; 48 h) potently and selectively downregulates RTN3 protein levels in Huh-7 cells, with a partial reduction in RTN3 mRNA, suggesting a post-transcriptional component to the protein depletion[2].
PS1097 (3-4 days post-viral infection) potently inhibits BVDV-induced cytopathogenicity in MDBK cells with an EC50 of 1.3 μM and shows no significant cytotoxicity up to 100 μM[3].
PS1097 potently inhibits purified BVDV NS5B∆24 polymerase activity with an IC50 of 0.64 μM[3].

Cell Line:Huh-7 cells, Vero E6 cells
-
Concentration:0.6 μM (1× EC50), 3 μM (5× EC50), 6 μM (10× EC50)
-
Incubation Time:48 h
-
Result:Dose-dependently reduced ZIKV NS5 protein levels in both Huh-7 and Vero E6 cells.
Drastically reduced NS5 protein levels at 6 μM compared to untreated infected cells.
Caused corresponding reductions in viral RNA released into supernatants that mirrored intracellular protein levels.
-
Cell Line:Huh-7 cells
-
Concentration:6 μM
-
Incubation Time:48 h
-
Result:Caused a significant, selective reduction in RTN3 protein levels (both long and short isoforms) compared to untreated cells, while RTN4, FAM134B, and TMEM41B protein levels remained unchanged.
Reduced RTN3 mRNA levels by approximately 50%, which contributes to but does not fully account for the marked depletion of RTN3 protein.
