Apilimod mesylate (STA 5326 mesylate) is a potent IL-12/IL-23 inhibitor.

YM201636 (IC50=33 nM), a specific PIKfyve inhibitor, is less effective to p110α and insensitive to Fabl, which is yeast orthologue.

Apilimod (STA 5326) inhibits the production of IL-12 and IL-23 and reduces dendritic cell infiltration in psoriasis.

Vacuolin-1 is a cell-permeable inhibitor of Ca2+ dependent fusion of lysosomes to the cell membrane. It acts by inhibiting release of lysosomal content.vacuolin‐1 is a potent and selective PIKfyve inhibitor and inhibits late‐stage autophagy by impairing lysosomal maturation

APY0201 is a effective, highly specific, ATP-competitive PIKfyve inhibitor (IC50: 5.2 nM). It can interrupt the conversion of phosphatidylinositol 3-phosphate (PtdIns3P) to PtdIns(3, 5)P2.

MOMIPP is a PIKfyve inhibitor and a macropinocytosis inducer. MOMIPP readily penetrates the blood-brain barrier and is moderately effective in suppressing progression of intracerebral glioblastoma xenografts[1][2].
