| Description | Ibuprofen is an anti-inflammatory inhibitor targeting COX-1 and COX-2 with IC50 of 13 μM and 370 μM, respectively.In Vitro:Ibuprofen inhibits the enzyme cyclooxygenase COX-1 and COX-2, which convert arachidonic acid to prostaglandin H2 (PGH2). Its action is similar to aspirin, indomethacin and all other NSAIDs in intact cells, broken cells, and purified enzyme preparations[1]. Ibuprofen inhibits the constitutive activation of NF-κB and IKKα in the androgen-independent prostate tumor cells PC-3 and DU-145. It sensitizes prostate cells to ionizing radiation and blocks stimulated activation of NF-κB following exposure to TNFα or ionizing radiation in the androgen-sensitive prostate tumor cell line LNCaP. Both of these cannot be attributed directly to inhibition of IκB-α kinase but to inhibition of an upstream regulator of IKKα[2]. Ibuprofen exerts an anticancer effect by reducing survival of cancer cells. Ibuprofen is more efficacious than aspirin and acetaminophen, and comparable with (R)-flurbiprofen and indomethacin in induction of p75NTR protein expression in cell lines from bladder and other organs[3].In Vivo:Ibuprofen reacts with the heme group of cyclooxygenase to prevent arachidonic acid conversion. Prior exposure to Ibuprofen in vivo protects cyclooxygenase completely from the irreversible effects of aspirin in platelets[4]. Ibuprofen treatment is effective in attenuating joint inflammation and early articular cartilage degeneration in the adult female Sprague-Dawley rat model induced by high-repetition and high-force (HRHF) task. It dose this by blocking the increases in serum C1 and 2C (a biomarker of collagen I and II degradation) as well as the ratio of collagen degradation to synthesis (C1, 2C/CPII, the latter a biomarker of collage type II synthesis) induced by HRHF[5].

Ibuprofen is an inhibitor of cyclooxygenase 1 and cyclooxygenase 2 with IC50 values of 12 and 80 μM, respectively [1].
Cyclooxygenase (COX) is an enzyme that is responsible for the formation of prostaglandins, prostacyclin and thromboxane.
In HCT-116 p53wt or HCT-116 p53-/-colon carcinoma cell lines, S- and R-ibuprofen induced apoptosis and blocked cell cycle is in part dependent on p53. The anti-proliferative effects were significantly higher in the p53wt cell line than in the p53-deficient cells [2].
In nude mice model bearing HCT-116 p53wt and p53-/- xenografts, R-ibuprofen significantly inhibited the growth of p53wt expressing xenografts and only a small inhibition of p53-/- xenografts [2]. In hypercholesterolemic animals, ibuprofen reduced the levels of total cholesterol, VLDL, LDL, triglycerides and atherogenic index. Also, ibuprofen inhibited COX enzymes and inhibited the generation of free radicals during prostaglandins synthesis, which reduced the levels of lipid peroxidation, superoxide dismutase [3]. In rats, ibuprofen (60 mg/kg) improved mechanical hyperalgesia through reducing central hyperexcitability [4].

The Effect of Ibuprofen on Cytokine Production by Mononuclear Cells from Schizophrenic Patients.[Pubmed:28374670]
Folia Biol (Praha). 2017;63(1):13-19.
The existence of a restrained inflammatory state in schizophrenic individuals posed the question whether anti-inflammatory drugs may exert antipsychotic effects. Therefore, the effect of Ibuprofen (IB) on cytokine production by human peripheral blood mononuclear cells (PBMC) from schizophrenic patients was examined and compared to that of healthy subjects. PBMC from 25 schizophrenic patients and 24 healthy volunteers were incubated for 24 h with lipopolysaccharide (LPS) in the absence or presence of various concentrations of IB. The levels of IL-1beta, IL-6, TNF-alpha, IL-10 and IL-1ra in the supernatants were tested applying ELISA kits. The secretion of TNF-alpha by cells from schizophrenic patients was significantly lower compared with controls. IB caused stimulation of TNF-alpha and IL-6 production by cells of the two groups and enhanced IL-1beta secretion by cells from schizophrenic patients. IB inhibited IL-1ra and IL-10 generation by cells from the two groups. Without IB, IL-1ra secretion was negatively correlated with the disease severity, while 200 mug/ml of IB positively correlated with the PANSS total score. IL-10 production was positively correlated with the PANSS positive subscale score both in the absence or presence of IB. The findings suggest that the effect of IB on the production of inflammatory cytokines may benefit the health of schizophrenic patients.
Significant solubility of carbon dioxide in Soluplus((R)) facilitates impregnation of ibuprofen using supercritical fluid technology.[Pubmed:28375669]
Pharm Dev Technol. 2018 Sep;23(7):697-705.
Treatment of Soluplus((R)) with supercritical carbon dioxide allows promising applications in preparing dispersions of amorphous solids. Several characterization techniques were employed to reveal this effect, including CO2 gas sorption under high pressure and physicochemical characterizations techniques. A gravimetric method was used to determine the solubility of carbon dioxide in the polymer at elevated pressure. The following physicochemical characterizations were used: thermal analysis, X-ray diffraction, Fourier transform, infrared spectroscopy and scanning electron microscopy. Drug loading of the polymer with Ibuprofen as a model drug was also investigated. The proposed treatment with supercritical carbon dioxide allows to prepare solid solutions of Soluplus((R)) in less than two hours at temperatures that do not exceed 45 degrees C, which is a great advantage to be used for thermolabile drugs. The advantages of using this technology for Soluplus((R)) formulations lies behind the high sorption capability of carbon dioxide inside the polymer. This will ensure rapid diffusion of the dissolved/dispersed drug inside the polymer under process conditions and rapid precipitation of the drug in the amorphous form during depressurization accompanied by foaming of the polymer.
Encapsulation of Ibuprofen in CD-MOF and Related Bioavailability Studies.[Pubmed:28355489]
Mol Pharm. 2017 May 1;14(5):1831-1839.
Although Ibuprofen is one of the most widely used nonsteroidal anti-inflammatory drugs (NSAIDs), it exhibits poor solubility in aqueous and physiological environments as a free acid. In order to improve its oral bioavailability and rate of uptake, extensive research into the development of new formulations of Ibuprofen has been undertaken, including the use of excipients as well as Ibuprofen salts, such as Ibuprofen lysinate and Ibuprofen, sodium salt. The ultimate goals of these studies are to reduce the time required for maximum uptake of Ibuprofen, as this period of time is directly proportional to the rate of onset of analgesic/anti-inflammatory effects, and to increase the half-life of the drug within the body; that is, the duration of action of the effects of the drug. Herein, we present a pharmaceutical cocrystal of Ibuprofen and the biocompatible metal-organic framework called CD-MOF. This metal-organic framework (MOF) is based upon gamma-cyclodextrin (gamma-CD) tori that are coordinated to alkali metal cations (e.g., K(+) ions) on both their primary and secondary faces in an alternating manner to form a porous framework built up from (gamma-CD)6 cubes. We show that Ibuprofen can be incorporated within CD-MOF-1 either by (i) a crystallization process using the potassium salt of Ibuprofen as the alkali cation source for production of the MOF or by (ii) absorption and deprotonation of the free-acid, leading to an uptake of 23-26 wt % of Ibuprofen within the CD-MOF. In vitro viability studies revealed that the CD-MOF is inherently not affecting the viability of the cells with no IC50 value determined up to a concentration of 100 muM. Bioavailability investigations were conducted on mice, and the Ibuprofen/CD-MOF pharmaceutical cocrystal was compared to control samples of the potassium salt of Ibuprofen in the presence and absence of gamma-CD. From these animal studies, we observed that the Ibuprofen/CD-MOF-1 cocrystal exhibits the same rapid uptake of Ibuprofen as the Ibuprofen potassium salt control sample with a peak plasma concentration observed within 20 min, and the cocrystal has the added benefit of a 100% longer half-life in blood plasma samples and is intrinsically less hygroscopic than the pure salt form.
