PAV-104
Based on 1 Customer Validation
PAV-104 (MAV-104) is a host-targeted, pan-respiratory viral assembly inhibitor. PAV-104 targets a small subset of the host protein 14-3-3 within a transient multi-protein complex. PAV-104 inhibits SARS-CoV-2 replication by blocking post-entry viral assembly/budding through interaction with viral nucleocapsid (N) protein and interference with its oligomerization. PAV-104 is orally active in cats and shows favorable pharmacokinetic properties in rats. PAV-104 can be used for the study of COVID-19 and other respiratory viral infections, including Feline Infectious Peritonitis (FIP).

PAV-104 (MAV-104) (0-5000 nM; 48 h) shows a CC50 of 3732 nM in Calu-3 cells[1].
PAV-104 (6.25-100 nM; 1 h preincubation; 24 h post-infection) dose-dependently inhibits SARS-CoV-2 replication and suppresses infectious virus release in supernatants of SARS-CoV-2-infected Calu-3 cells[1].
PAV-104 (6.25-100 nM; 1 h preincubation; 72 h post-infection) reduces SARS-CoV-2-infected Calu-3 cells[1].
PAV-104 (0.001-1000 nM; 1 h preincubation; 48 h post-infection) inhibits SARS-CoV-2 replication in Calu-3 cells (EC50 = 1.7 nM, EC90 = 23.5 nM) and suppresses infectious SARS-CoV-2 titers in cell supernatants (EC50 = 0.5 nM, EC90 = 10.3 nM)[1].
PAV-104 (100 nM; 36 h post-infection) suppresses SARS-CoV-2 Gamma variant replication in primary human airway epithelial cells (AECs) (achieving > 99% inhibition at the tested concentration), and reduces SARS-CoV-2 Delta and Omicron variant replication in air–liquid interface (ALI) cultured primary AECs[1].
PAV-104 (50 nM; 1 h pre-infection treatment) does not inhibit SARS-CoV-2 release into supernatants at 24 h post-infection[1].
PAV-104 (50 nM; 20 min post-entry treatment; 24 h incubation) reduces SARS-CoV-2 viral titers in Calu-3 cell supernatants[1].
PAV-104 (100 nM; post-entry treatment; 36 h incubation) reduces SARS-CoV-2 N gene expression in primary AECs at ALI culture compared to pre-infection treatment[1].
PAV-104 (6.25-100 nM; 60 h) dose-dependently reduces SARS-CoV-2 structural proteins (N, M, E, S) in ultracentrifuged pellets of VLP-producing HEK293T cell supernatants, and does not affect protein synthesis or steady-state actin levels in cell lysates[1].
PAV-104 (0-100 nM; 60 h) inhibits SARS-CoV-2 virus-like particle (VLP) production in HEK293T cells transfected with N, M, E, and S proteins in a dose-dependent manner and has no effect on extracellular vesicle secretion from empty vector-transfected cells[1].
PAV-104 (50 nM; 2 h entry; 18 h post-entry incubation) in single-cycle infectious SARS-CoV-2 ΔS-VRP-infected Calu-3 cells does not affect N mRNA levels or N protein synthesis, but inhibits viral particle release into supernatants[1].
PAV-104 (cell extracts incubated for 1 h; eluted with free drug for 2 h) binds directly to SARS-CoV-2 N protein in Calu-3 cell extracts (Delta and Omicron variants)[1].
PAV-104 (20 h ultracentrifugation) inhibits the oligomerization of SARS-CoV-2 N protein in N-transfected HEK293T cells, and shows a reduction in the N intermediate complex (Fractions 20-22) in glycerol gradient ultracentrifugation[1].
PAV-104 (100 nM; 36 h post-infection) in SARS-CoV-2-infected primary AECs reverses SARS-CoV-2 induction of type-I interferon response and the maturation of nucleoprotein signaling pathway[1].
