Ibuprofen Lysine (Arflamin, Ibuprofen lysinate, NeoProfen, Saren), the pyridyl ester of ibuprofen, is an anti-inflammatory drug that belongs to the non-steroidal anti-inflammatory drug (NSAIDs) class. The MOA (mechanism of action) of Ibuprofen Lysine is to act as a non-selective COX inhibitor with an IC50 of 0.33 mM, and also has an antiplatelet effect, though Ibuprofen Lysine is relatively mild and short-lived when compared with that of aspirin or other agents.
| ln Vitro |
L-lysine (ibuprofen) (24 h) suppresses the activity of COX-1 and COX-2, with IC50 values of 13 μM and 370 μM, respectively[1]. Ibuprofen (500 μM, 48 h) L-lysine causes apoptosis in AGS cells (adenocarcinoma stomach cell line) and suppresses angiogenesis and cell proliferation[2]. In AGS cells, ibuprofen (500 μM, 48 h) L-lysine upregulates wild type P53 and Bax gene RNA levels while downregulating transcription of Akt, VEGF-A, PCNA, Bcl2, OCT3/4, and CD44 genes[2]. In both primary CF nasal epithelial cells and cystic fibrosis (CF) cell models, ibuprofen (500 μM, 24 hours) L-lysine stimulates microtubule elongation to the cell periphery and restores microtubule-dependent intracellular cholesterol transport[3]. Through photosensitization, ibuprofen (500 μM, 24 h) L-lysine amplifies UV-induced cell death in MCF-7 and MDA-MB-231 cells[4].

| ln Vivo |
In a model of postpartum breast cancer, ibuprofen (300 mg/kg; po; daily, for 14 days) and L-lysine diminish overall tumor development and improve anti-tumor immune features without causing negative autoimmune reactions[5]. In a rat model of chronic Oxaliplatin-induced peripheral neuropathy, L-lysine lowers the incidence of neuropathy, as does ibuprofen (60 mg/kg; ih; every other day for 15 days)[6]. L-lysine reduces muscle growth (average muscle fiber cross-sectional area) without altering the control of supraspinatus tendon adaptations to exercise, when combined with ibuprofen (20 mg/kg; po; every 12 hours, 5 doses total)[7]. In a rat model of chronic lung infection, ibuprofen (35 mg/kg; po; twice daily) and L-lysine reduce the inflammatory response to pseudomonas aeruginosa[8].

| Cell Assay |
Cell Viability Assay[2]
Cell Types: AGS cells Tested Concentrations: 100-1000 μM Incubation Duration: 24 h, 48 h Experimental Results: Inhibited AGS cell viability with IC50 values of 630 μM (trypan blue staining, 24 h), 456 μM (neutral red assay, 24 h), 549 μM (trypan blue staining, 48 h) and 408 μM (neutral red assay, 48 h). |
| Animal Protocol |
Animal/Disease Models: Syngeneic (D2A1) orthotopic Balb/c mouse model of PPBC (postpartum)[5]
Doses: 300 mg/kg, daily for 14 days Route of Administration: Fed in animal feedings (added to pulverized standard chow and mixed dry, then mixed with water, made into chow pellets and dried thoroughly) Experimental Results: Suppresed tumor growth, decreased presence of immature monocytes and increased numbers of T cells. Enhanced Th1 associated cytokines as well as promoted tumor border accumulation of T cells. Animal/Disease Models: Oxaliplatin‑induced peripheral neuropathy[6] Doses: 60 mg/kg, every second day for 15 days Route of Administration: subcutaneous (sc) injection Experimental Results: Lowered sensory nerve conduction velocity (SNCV). |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
