Biochem/physiol Actions

Apilimod (STA-5326) is a potent, orally active and selective inhibitor of the cytokines IL-12 and IL-23. Apilimod selectively suppresses synthesis of IL-12 and IL-23 by inhibition of phosphotransferase activity of TLR-4 regulator lipid kinase PIKfyve (phosphatidylinositol-3-phosphate 5-kinase). It suppresses Th1 cells response in vivo and reduces inflammatory histopathologic changes. Also, it exhibits strong anti COVID-19 activity in two cell lines (Vero E6:IC50 < 0.08 μM; A549-ACE2:IC50 = 0.007 μM). Apilimod potently reduces entry of SARS-CoV S pseudovirions on 293/hACE2 cells.

Toll-like receptor (TLR) signaling is a key component of innate immunity. Aberrant TLR activation leads to immune disorders via dysregulation of cytokine production, such as IL-12/IL-23. Herein, we identify and characterize PIKfyve, a lipid kinase, as a critical player in

Since 2002, beta coronaviruses (CoV) have caused three zoonotic outbreaks, SARS-CoV in 2002-2003, MERS-CoV in 2012, and the newly emerged SARS-CoV-2 in late 2019. However, little is currently known about the biology of SARS-CoV-2. Here, using SARS-CoV-2 S protein pseudovirus
