In vitro study | Tarenflurbil ((R)-Flurbiprofen) can significantly reduce Aβ secretion, but at the same time, increases the level of intracellular Aβ. The binding between [ 3 H]9-cis-RA and RXRα is competitively inhibited by both unlabeled (R)-Flurbiprofen and 9-cis-RA. (R)-Flurbiprofen can interfere with the interaction between RXRα and 9-cis-retinoid acid (9-cis-RA), and that 9-cis-RA decreases Tarenflurbil ((R)-Flurbiprofen)’s reduction of Aβ secretion. Tarenflurbil ((R)-Flurbiprofen) treatment significantly increases the levels of intracellular Aβ species. The well characterized, nonsteroidal anti-inflammatory drug (nonsteroidal anti-inflammatory drug), Tarenflurbil ((R)-Flurbiprofen) affects only Aβ and not Notch β formation, indicating that second generation GSMs and nonsteroidal anti-inflammatory drug-based GSMs have different modes of action regarding Notch processing. |
In vivo study | Effects of the early and late onset of treatment with Tarenflurbil ((R)-Flurbiprofen) are assessed in C57BL6/J mice that develop a non-remitting form of the disease, and in SJL mice that develop a relapsing-remitting (RR)-EAE. Tarenflurbil ((R)-Flurbiprofen) completely prevents the development of clinical EAE scores in C57BL6/J mice when the treatment is started within 3 days after immunization. This regimen is referred to as preventive treatment. The effect is dose-dependent, and the minimum daily dose for complete prevention is 5 mg/kg/day. Effects of Tarenflurbil ((R)-Flurbiprofen) are comparable to those of Fingolimod (FTY720, 0.5 mg/kg/day), which is used as the positive control. Tarenflurbil ((R)-Flurbiprofen) also significantly reduces clinical EAE scores in C57BL6/J mice when treatment is started shortly before onset of clinical manifestations, referred to as semi-therapeutic (10 mg/kg/day) and reduces clinical scores when the treatment is initiated after full development of the disease on day 13 (5 mg/g/day). |

toxicity | Non-steroidal anti-inflammatory drugs (NSAIDs) have anti-inflammatory, analgesic and antipyretic effects, the list of toxicity from small to large is naphtone, salenoxyl, sulindac, diclofenac, ibuprofen, ketoprofen, aspirin, naproxen, tolmetin, flurbiprofen, yantongxikang, phenoxyibuprofen, indomethacin, chloromethanoic acid. Aspirin may be the first choice for traditional NSAID drugs. If children cannot tolerate their adverse reactions during treatment, other non-steroidal anti-inflammatory drugs can be used. Selective COX-2 inhibitors have been developed that will all replace traditional NSAIDs. The listed selective COX-2 inhibitors include Nimesulide (Nimesulide), rofecoxib (vioxab), celecoxib (celecoxib), etodolac (Rodine), meloxicam, etc. A recent large-scale, international, multicenter, randomized, double-blind, prospective study showed that selective COX-2 inhibitors had few gastrointestinal and renal side effects and had no significant effect on platelet function, it can be used as the first choice for early combination therapy in children with JRA instead of aspirin. |
adverse reactions | The most common adverse reactions were dyspepsia, stomach discomfort, etc., occasionally Head Pain, rash, etc. Peptic ulcer, bronchial asthma patients and pregnant women, lactating women should not take. other adverse reactions were Nausea, Diarrhea, Abdominal Pain, blurred vision, urinary tract infection, dermatitis and so on. A small number of liver transaminase increased, continue medication, may develop, can remain unchanged or disappear. When instilled into the eye, there was mild tingling and burning sensation and/or visual disturbance. There is a report that the bleeding time is prolonged due to the influence of platelet aggregation, and the tendency of increasing intraocular hemorrhage after the application of this drug in ophthalmic surgery is reported.
