WEHI-P8
Based on 1 Customer Validation
WEHI-P8 is an orally active SARS-CoV-2 papain-like protease (PLpro) inhibitor with an IC50 of 12 nM and a Kd of 9.0 nM. WEHI-P8 reduces viral load, body weight loss, pulmonary inflammation, immune cell infiltration and pro-inflammatory mediator levels in SARS-CoV-2-infected mice. WEHI-P8 prevents pulmonary hemorrhage, immune cell infiltration, fibrotic remodeling and neuroinflammation, and improves cognitive function in a mouse model of post-acute sequelae of SARS-CoV-2 infection (PASC). WEHI-P8 is applicable for the research of COVID-19 and PASC.

Biological Activity
WEHI-P8 (16-24 h) inhibits the activity of SARS-CoV-2 PLpro in FRET assays using HEK293T cells, with an EC50 of 298 nM[1].
WEHI-P8 (0-5 μM) inhibits SARS-CoV-2 replication in Vero cells in plaque assays, with an antiviral EC50 of 360 nM, which slightly decreases to 290 nM when combined with a P-glycoprotein inhibitor[1].

WEHI-P8 (150 mg/kg; p.o.; administered 2 h before infection, 6 h after infection, and 24 h after infection) prevents acute infection-induced mortality, alleviates long-term pulmonary pathological damage, mitigates neuroinflammation, and improves cognitive function in a PASC mouse model[1].

-
Animal Model:C57BL/6 J (WT, 6-8 weeks old, both sexes, intranasal infection with mouse-adapted SARS-CoV-2 P21 strain)[1]
-
Dosage:100 mg/kg; 150 mg/kg
-
Administration:p.o.; 6 h, 24 h, 48 h post-infection
-
Result:Reduced lung viral burden.
Prevented infection-induced weight loss.
Reduced lung haemorrhage and inflammation to mild levels (100 mg/kg) or minimal/unremarkable levels (150 mg/kg).
Significantly reduced lung macrophage and neutrophil counts (100 mg/kg); significantly reduced lung macrophage, neutrophil, and T cell counts (150 mg/kg).
Significantly reduced lung levels of multiple pro-inflammatory cytokines/chemokines including IFN-γ, IL-1β, TNF, IL-18, IL-6, GROα, and MCP-1.
Reduced lung viral burden to levels below the lower limit of detection (150 mg/kg).

-
Dosage:150 mg/kg
-
Administration:p.o.; 2 h pre-infection, 6 h post-infection, 24 h post-infection
-
Result:Ensured 100% survival of treated mice during the acute infection phase, compared to vehicle-treated mice requiring euthanasia.
Prevented infection-induced weight loss during the acute phase.
Reduced lung haemorrhage and inflammatory foci to near-unremarkable levels, with lungs histologically similar to mock-infected mice.
Significantly reduced microglial activation (increased microglial projection area) in the hippocampus, indicating reduced neuroinflammation.
Significantly increased time spent exploring a novel object in the Novel Object Recognition Test, indicating improved cognitive function compared to vehicle and PLT-treated mice.
Rescued the infection-induced reduction in total distance travelled during behavioural testing in female mice, a deficit not mitigated by PLT treatment.
