IL-17A 8.3 (pIC50)
Interleukin-17A (IL-17A), a pro-inflammatory cytokine produced primarily by Th17 cells. IL-17A is implicated in the pathogenesis of autoimmune diseases (e.g., psoriasis, rheumatoid arthritis, ankylosing spondylitis), cancer (tumor promotion or suppression depending on context), and neurodegenerative disorders. |
|---|---|
| ln Vitro |
A biochemical or cell-based assay measured a pIC50 of 8.3 for IL-17A modulator-2, which corresponds to an IC50 of approximately 5 nM. It inhibits the biological action of IL-17A, presumably by blocking IL-17A binding to its receptor or by inhibiting downstream signaling.
|
| ln Vivo |
No published in vivo data. Based on its potent in vitro activity (pIC50 = 8.3), IL-17A modulator-2 would be expected to reduce IL-17A-mediated inflammation in vivo, such as attenuating skin inflammation in psoriasis models or reducing joint swelling in arthritis models, though this remains to be validated.
|
| Enzyme Assay |
Binding affinity for IL-17A is assessed via a biochemical assay (e.g., AlphaLISA or TR-FRET). Recombinant human IL-17A and a labeled IL-17A antibody or receptor are incubated with serially diluted modulator-2 (0.001-10 uM). The assay signal is measured to calculate the half-maximal inhibitory concentration (pIC50 = 8.3).
|
| Cell Assay |
For in vitro cellular assays, IL-17A-responsive cells (e.g., HT-29 or human dermal fibroblasts) are seeded in 96-well plates. Cells are pre-incubated with serially diluted IL-17A modulator-2 (0.1-1000 nM) for 1 hour, then stimulated with recombinant human IL-17A (10 ng/mL) for 24 hours. Supernatants are collected, and CXCL8 (IL-8) or CCL20 levels are measured by ELISA. The IC50 is calculated from the dose-response curve.
|
| Animal Protocol |
No published in vivo data. For research use, the imiquimod (IMQ)-induced psoriasis-like mouse model is used. BALB/c mice are treated topically with IMQ cream on the shaved back for 5-7 days. IL-17A modulator-2 is administered orally or intraperitoneally at 10-50 mg/kg daily. PASI scores (erythema, scaling, thickness) are recorded daily. On day 5-7, skin biopsies are taken for histopathological analysis (H&E staining) and for qPCR or ELISA measurement of inflammatory cytokines (IL-6, TNF-alpha, IL-22).
|
| ADME/Pharmacokinetics |
IL-17A modulator-2 has a molecular weight of 577.63 g/mol and a formula of C33H31N5O5. DMSO solubility is 100 mg/mL (173.12 mM). Detailed PK parameters (e.g., half-life, oral bioavailability) are not publicly available; as a small molecule, PK properties will depend on formulation and administration route, with oral bioavailability likely moderate.
|
| Toxicity/Toxicokinetics |
Detailed toxicological data are not publicly available. As a small-molecule IL-17A modulator, potential toxicities may include increased susceptibility to infections (consistent with IL-17A blockade) and gastrointestinal disturbances. No severe toxicities have been reported in research models.
