Ibuprofen

Ibuprofen ((±)-Ibuprofen) is a potent, orally active, selective COX-1 inhibitor with an IC₅₀ value of 13 μM. Ibuprofen inhibits cell proliferation, angiogenesis, and induces cell apoptosis. Ibuprofen is a nonsteroidal anti-inflammatory agent and a nitric oxide (NO) donor. Ibuprofen ((±)-Ibuprofen) can be used in the research of pain, swelling, inflammation, infection, immunology, cancers^[1][2][5][8]. IC50 & Target:IC50: 13 μM (COX-1), 370 μM (COX-2) In Vitro:Ibuprofen (24 h) inhibits COX-1 and COX-2 activity with IC₅₀ values of 13 μM and 370 μM^[1].
Ibuprofen (500 μM, 48 h) inhibits cell proliferation and angiogenesis, and induces apoptosis in AGS cells (Adenocarcinoma gastric cell line)^[2].
Ibuprofen (500 μM, 48 h) downregulates transcription of Akt, VEGF-A, PCNA, Bcl2, OCT3/4 and CD44 genes, but upregulates RNA levels of wild type P53 and Bax genes in AGS cell^[2].
Ibuprofen (500 μM, 24 h) restores microtubule reformation, microtubule-dependent intracellular cholesterol transport, and induces extension of microtubules to the cell periphery in both cystic fibrosis (CF) cell models and primary CF nasal epithelial cells^[3].
Ibuprofen (500 μM, 24 h) enhances UV-induced cell death in MCF-7 cells and MDA-MB-231 cells by a photosensitization process^[4].
In Vivo:Ibuprofen (300 mg/kg; p.o.; daily, for 14 days) reduces overall tumor growth and enhances anti-tumor immune characteristics without adverse autoimmune reactions in a model of postpartum breast cancer^[5].
Ibuprofen (60 mg/kg; i.h.; every second day for 15 days) reduces the risk of neuropathy in a rat model of chronic Oxaliplatin induced peripheral neuropathy^[6].
Ibuprofen (20 mg/kg; p.o.; every 12 hours, 5 doses total) decreases muscle growth (average muscle fiber cross-sectional area) without affecting regulation of supraspinatus tendon adaptions to exercise^[7].
Ibuprofen (35 mg/kg; p.o.; twice daily) attenuates the Inflammatory response to pseudomonas aeruginosa in a rat model of chronic pulmonary infection^[8].
