Apilimod
(Synonyms: 阿匹莫德; STA 5326) 目录号 : GC35373
Apilimod (STA-5326) is a potent and orally-available inhibitor of the cytokines interleukin-12 (IL-12) and interleukin-23 (IL-23) with the potential to treat certain autoimmune and inflammatory diseases. Apilimod (STA-5326) inhibits IL-12 with IC50 of 1 nM, 1 nM and 2 nM, in IFN-γ/SAC-stimulated human PBMCs, human monocytes and mouse PBMCs, respectively.

Cell experiment: | Cervical lymph node cells obtained from immunized mice on day 18 (2×105 cells/well) arecultured in 0.2 mL RPMI 1640 containing 10 mM HEPES, 0.1 mM nonessential amino acid, 1 mM sodium pyruvate, 100 U/mL penicillin, 100 μg/mL streptomycin, 1×10-5 M 2-mercaptoethanol, 10% FCS, and 10 μg/mL IRBP1-20. For cytokine assay, supernatants are collected after 72 hours and analysed for IFN-γ, IL-4 and IL-17 by quantitative capture ELISA using quantikine ELISA kits and mouse IL-17 ELISA Ready-SET-Go kits. Cell proliferation is evaluated using a cell proliferation assay. |
Animal experiment: | In most experiments, 5 mg/kg or 20 mg/kg Apilimod or vehicle only (0.5% carboxyl methyl cellulose) is orally administered once a day for six days a week from day 0 to day 14 after immunization. In the effector phase experiments, 20 mg/kg Apilimod or vehicle is orally administered once a day, from day 9 to day 14 after immunization. |

Apilimod selectively inhibits TLR-induced cytokine expression. It selectively inhibits the production of IL12p40, whereas it has little effect on IL8 production in THP-1 cells[1]. Apilimod reduces not only PtdIns(3,5)P2 production but also that of PtdIns5P in intact cells[2].

Apilimod alters TGFβ signaling pathway and prevents cardiac fibrotic remodeling
Theranostics 2021 Apr 19;11(13):6491-6506.PMID:33995670DOI:10.7150/thno.55821.
Rationale: TGFβ signaling pathway controls tissue fibrotic remodeling, a hallmark in many diseases leading to organ injury and failure. In this study, we address the role of Apilimod, a pharmacological inhibitor of the lipid kinase PIKfyve, in the regulation of cardiac pathological fibrotic remodeling and TGFβ signaling pathway. Methods: The effects of Apilimod treatment on myocardial fibrosis, hypertrophy and cardiac function were assessed in vivo in a mouse model of pressure overload-induced heart failure. Primary cardiac fibroblasts and HeLa cells treated with Apilimod as well as genetic mutation of PIKfyve in mouse embryonic fibroblasts were used as cell models. Results: When administered in vivo, Apilimod reduced myocardial interstitial fibrosis development and prevented left ventricular dysfunction. In vitro, Apilimod controlled TGFβ-dependent activation of primary murine cardiac fibroblasts. Mechanistically, both Apilimod and genetic mutation of PIKfyve induced TGFβ receptor blockade in intracellular vesicles, negatively modulating its downstream signaling pathway and ultimately dampening TGFβ response. Conclusions: Altogether, our findings propose a novel function for PIKfyve in the control of myocardial fibrotic remodeling and the TGFβ signaling pathway, therefore opening the way to new therapeutic perspectives to prevent adverse fibrotic remodeling using Apilimod treatment.
The PIKfyve Inhibitor Apilimod: A Double-Edged Sword against COVID-19
Cells 2020 Dec 27;10(1):30.PMID:33375410DOI:10.3390/cells10010030.
The PIKfyve inhibitor Apilimod is currently undergoing clinical trials for treatment of COVID-19. However, although Apilimod might prevent viral invasion by inhibiting host cell proteases, the same proteases are critical for antigen presentation leading to T cell activation and there is good evidence from both in vitro studies and the clinic that Apilimod blocks antiviral immune responses. We therefore warn that the immunosuppression observed in many COVID-19 patients might be aggravated by Apilimod.
ELAVL4, splicing, and glutamatergic dysfunction precede neuron loss in MAPT mutation cerebral organoids
Cell 2021 Aug 19;184(17):4547-4563.e17.PMID:34314701DOI:10.1016/j.cell.2021.07.003.
Frontotemporal dementia (FTD) because of MAPT mutation causes pathological accumulation of tau and glutamatergic cortical neuronal death by unknown mechanisms. We used human induced pluripotent stem cell (iPSC)-derived cerebral organoids expressing tau-V337M and isogenic corrected controls to discover early alterations because of the mutation that precede neurodegeneration. At 2 months, mutant organoids show upregulated expression of MAPT, glutamatergic signaling pathways, and regulators, including the RNA-binding protein ELAVL4, and increased stress granules. Over the following 4 months, mutant organoids accumulate splicing changes, disruption of autophagy function, and build-up of tau and P-tau-S396. By 6 months, tau-V337M organoids show specific loss of glutamatergic neurons as seen in individuals with FTD. Mutant neurons are susceptible to glutamate toxicity, which can be rescued pharmacologically by the PIKFYVE kinase inhibitor Apilimod. Our results demonstrate a sequence of events that precede neurodegeneration, revealing molecular pathways associated with glutamate signaling as potential targets for therapeutic intervention in FTD.
Discovery of SARS-CoV-2 antiviral drugs through large-scale compound repurposing
Nature 2020 Oct;586(7827):113-119.PMID:32707573DOI:10.1038/s41586-020-2577-1.
The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 2019 has triggered an ongoing global pandemic of the severe pneumonia-like disease coronavirus disease 2019 (COVID-19)1. The development of a vaccine is likely to take at least 12-18 months, and the typical timeline for approval of a new antiviral therapeutic agent can exceed 10 years. Thus, repurposing of known drugs could substantially accelerate the deployment of new therapies for COVID-19. Here we profiled a library of drugs encompassing approximately 12,000 clinical-stage or Food and Drug Administration (FDA)-approved small molecules to identify candidate therapeutic drugs for COVID-19. We report the identification of 100 molecules that inhibit viral replication of SARS-CoV-2, including 21 drugs that exhibit dose-response relationships. Of these, thirteen were found to harbour effective concentrations commensurate with probable achievable therapeutic doses in patients, including the PIKfyve kinase inhibitor apilimod2-4 and the cysteine protease inhibitors MDL-28170, Z LVG CHN2, VBY-825 and ONO 5334. Notably, MDL-28170, ONO 5334 and Apilimod were found to antagonize viral replication in human pneumocyte-like cells derived from induced pluripotent stem cells, and Apilimod also demonstrated antiviral efficacy in a primary human lung explant model. Since most of the molecules identified in this study have already advanced into the clinic, their known pharmacological and human safety profiles will enable accelerated preclinical and clinical evaluation of these drugs for the treatment of COVID-19.
Apilimod enhances specific productivity in recombinant CHO cells through cell cycle arrest and mediation of autophagy
Biotechnol J 2023 Feb;18(2):e2200147.PMID:36478399DOI:10.1002/biot.202200147.
Chinese hamster ovary (CHO) cells are expected to acquire the ability to produce higher recombinant therapeutic protein levels using various strategies. Genetic engineering targeting the cell cycle and autophagy pathways in the regulation of cell death in CHO cell cultures has received attention for enhancing the production of therapeutic proteins. In this study, we examined the small-molecule compound Apilimod, which was found to have a positive influence on recombinant protein expression in CHO cells. This was confirmed by selective blocking of the cell cycle at the G0/G1 phase. Apilimod treatment resulted in decreased expression of cyclin-dependent kinase 3 (CDK3) and Cyclin C and increased expression of cyclin-dependent kinase suppressor p27Kip1, which are critical regulators of G1 cell cycle progression and important targets controlling cell proliferation. Furthermore, total transcription factor EB (TFEB) was lower in apilimod-treated CHO cells than in control cells, resulting in decreased lysosome biogenesis and autophagy with Apilimod treatment. These multiple effects demonstrate the potential of Apilimod for development as a novel enhancer for the production of recombinant proteins in CHO cell engineering.
