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.
