Emerging evidence shows that FLU exerts protective effects in multiple organs, making it a promising candidate for topical ocular therapy. Developing an FLU eyedrop for glaucoma can address a significant treatment gap with potentially fewer side effects compared with conventional therapies. To optimise formulation development, precise quantification of FLU in ocular compartments such as aqueous humour, as well as systemic circulation, is essential to characterise drug absorption, ocular bioavailability, and safety. Methods: We developed and validated a UHPLC-MS method for FLU detection in aqueous humour and serum using simple sample preparation steps. Results: The 11-min-long reverse phase chromatography followed by SRM-based mass spectrometry detection provides a highly selective and sensitive FLU detection method. Our method was proved to be linear in the 0.0625–1.5 µg/mL range and was validated according to the EMA guidelines. Conclusions: The simplicity of sample preparation, the tolerable matrix effects, and the favourable detection parameters provide a robust tool for preclinical pharmacokinetic and pharmacodynamic studies of FLU’s ocular protective effects.}, year = {2026}, eissn = {1424-8247}, orcid-numbers = {Guba, Andrea/0009-0009-0535-2025;

We previously showed that the Sigma-1 receptor (S1R) agonist fluvoxamine protects against IRI and IRI-induced graft injury during transplantation. Here, we developed a novel compound, 'VCC904125', with potent S1R affinity and minimal blood-brain barrier penetration to mitigate renal IRI without psychoactive side effects. Mice were treated with VCC904125 before clamping the left renal pedicles, followed by contralateral nephrectomy. VCC904125 markedly alleviated BUN and serum creatinine levels, KIM-1 and NGAL expression, and structural damage at both 24 and 48 h after reperfusion. S1R activation by VCC904125 targets key pathways underlying IRI, including apoptosis and inflammation. VCC904125 treatment impeded the apoptotic p53-Bax pathway and influenced CaMKII-NF-κB signaling, resulting in diminished proinflammatory cytokine expression. In the ex vivo model, kidneys were perfused and stored in an HTK preservation solution supplemented with VCC904125 to simulate cold storage conditions before transplantation. VCC904125 ameliorated structural injury profoundly after cold ischemia. Taken together, S1R activation by VCC904125 decreases renal IRI via ameliorating apoptotic and inflammatory pathways. These results highlight the therapeutic promise of S1R activation in mitigating cold and warm ischemia and improving transplant outcomes.}, keywords = {Inflammation; STIMULATION; APOPTOSIS; PROTECTS; ISCHEMIA/REPERFUSION INJURY; FACTOR-KAPPA-B; Fluvoxamine; p53; Sigma-1 receptor; RENAL ISCHEMIA/REPERFUSION INJURY}, year = {2025}, eissn = {2045-2322}, orcid-numbers = {Tóth, Ákos Roland/0000-0002-2516-0508; Lakat, Tamás/0000-0001-9769-3728; Budai, András/0000-0002-4634-2140; Wágner, László József/0000-0001-6806-4076; Őrfi, László/0000-0001-6149-2385; Szabó, Attila/0000-0001-7321-9861; Fekete, Andrea/0000-0002-0210-153X; Hosszú, Ádám/0000-0002-8415-5637} }
