| Zhang et al. (2020) | Human testicular tissue (observational immunofluorescence) | FOXO4 localized to Leydig cell nuclei in elderly men (≥65 yrs) but cytoplasmic in young men (<30 yrs); valida FOXO4 como um(a) human aging target; correlated with reduziu steroidogenic enzyme expression | [4] |
| Bourgeois et al. (2025) | Solution NMR structural analysis (p53-FOXO4-DRI complex) | Identified p53 TAD2 as specific binding site; ambos(as) peptide and p53 TAD2 fold synergistically upon binding; phospho-Ser46/Thr55 aprimora affinity; HIV-TAT contributes stabilizing contacts | [2] |
Clinical / Human Trial Status
There are atualmente no completed or published human ensaios clinicos for FOXO4-DRI. O composto remains no(a) preclinical stage. Cleara Biotech describes itself como um(a) "preclinical-stage company" e e preparing the lead candidate CL04183 for Investigational New Drug (IND) applications. Some private wellness clinics offer FOXO4-DRI off-label; these nao sao registered ensaios clinicos e o(a) substance nao e FDA-aprovado(a) para human use.[1]
Dosage Summary
| Setting | Dose | Route / Schedule | Notes |
|---|---|---|---|
| In Vitro (standard) | 25 µM | Cell culture; 5 days exposure | Most common eficaz concentration[1][6] |
| In Vitro (range) | 6.25–50 µM | Cell culture | Dose-dependent senolytic effect[1] |
| In Vivo (standard) | 5 mg/kg | i.p. or i.v.; 3 doses every outro(a) day, or every 2 days for 1 month | Used across all principal efficacy studies[1][4][5] |
| Acute Toxicity | Up to 100 mg/kg | Single i.v. injection (BALB/c mice) | No mortality or observable toxicity within 24h |
