HIDE SMILES / InChI
Apilimod is a small molecule inhibitor of interleukin-12 and interleukin-23 synthesis thereby preventing IL-12/IL-23 mediated immune responses. Apilimod is also observed to inhibit the nuclear accumulation of NF-kappB protein family, and viral infections dependent on phosphatidylinositol-3-phosphate 5-kinase (PIKfyve). Apilimod has been investigated as a potential treatment for a number of autoimmune conditions.

CNS Activity

Sample Use Guides

In a phase IIa clinical trial for rheumatoid arthritis Apilimod mesylate was administered orally at a dose of 100 mg/day or 100 mg twice per day for up to 12 weeks.
Route of Administration: Oral
Apilimod was tested for inhibition of EBOV infection in three cell lines: Vero E6, Huh 7, and hMDM cells. For each cell type, cells were plated in 1 black opaque 96-well plate, for the evaluation of drug cytotoxicity, and 2 clear-bottom, 96-well Operetta plates, for the evaluation of drug efficacy. Apilimod was dissolved in dimethyl sulfoxide (DMSO) and diluted in DMEM with 10% FBS with the final DMSO concentration not exceeding 0.05%. The Apilimod solution was diluted two-fold in an 8-point dilution series and transferred to cell plates 1 h prior to virus infection.
