Description

Novel antipyretic analgesic drug and preparation method and application thereof
Technical Field
The invention relates to a novel antipyretic analgesic drug, a preparation method and application thereof, belonging to the technical field of medicines.
Background
Loxoprofen Sodium (Loxoprofen Sodium) is an anti-inflammatory analgesic drug which has the inhibition effect on cyclooxygenase COX-1 and COX-2. The loxoprofen sodium as the first synthesized aryl propionic acid precursor type non-steroidal anti-inflammatory drug has the advantages of obvious analgesic effect, and comparable anti-inflammatory and antipyretic effects with other similar drugs. Clinical trials show that after oral administration, the drug is metabolized to trans-OH type drug in human body, and meanwhile, the concentration distribution in liver and plasma is higher than that in other parts, and then the drug is rapidly converted into glucose conjugate and finally discharged out of body in the form of urine. The loxoprofen sodium has the analgesic effect which is 10 to 20 times stronger than that of ketoprofen, indometacin and naproxen, and also has the advantages of quick and obvious effect, small toxic and side effect, wide clinical application range and the like.
Through long-term clinical practice, COX-2 specific inhibitors that were previously considered "perfect" were also gradually exposed as follows:
the problems are as follows: (1) the curative effect is not increased, (2) the adverse reaction is not reduced; (3) the ulcer rate is reduced in a short term, and no difference exists in long-term use; (4) severe myocardial infarction occurs. Therefore, how to search for a non-steroidal anti-inflammatory drug with less toxic and side effects, higher bioavailability, and higher safety and effectiveness becomes one of the hot spots in the research and development of the industry.
There are many loxoprofen sodium derivatives that have been proposed so far, and for example, loxoprofen sodium derivatives have been proposed in Japanese patent application laid-open Nos. 58-4699 and 54-103852, International publication No. WO93/02999, and domestic patent application No. 201680000788.3, but they have various disadvantages.
Therefore, the problems to be solved clinically at present are that the absorption efficiency of the medicine is improved, the metabolic stability is improved, and the toxic and side effects are reduced.

Step 2. Collection of blood sample and separation of serum
Blood was collected from the retro-orbital venous plexus of the mice using flat capillaries 10, 20, 30 and 60 minutes and 2, 4, 8 and 24 hours after oral administration. Each group of 16 mice was subdivided into 4 groups and 2 blood samples were collected from 4 mice at each time period (10 minutes and 2 hours; 20 minutes and 4 hours; 30 minutes and 8 hours; 60 minutes and 24 hours). The blood was centrifuged (Micro 12, Hanil, Korea) at 13000rpm for 10 minutes to isolate serum for analysis.
Step 3 pharmacological analysis
Sera were treated for pharmacological analysis according to the method previously reported (Wang BYG et al, Biol. Pharm Bull. 30 (9) 1657-1662). The content of the test compound was analyzed by UPLC/MS (SIR mode). The quantization accuracy was 5ng/mL (detection limit: 1ng/mL), and the internal standard was used. Bioavailability of the compounds of the invention can be expressed as Cmax, Tmax and AUC values. The results are shown in Table 5.

*Cmax(ng/mL): the maximum serum concentration calculated or evaluated from the observed serum concentration or concentration-time curve.
*Tmax(hr):CmaxThe point in time of occurrence.
AUC (ng hr/ml) (area under curve; ng hr/ml): area under the serum concentration-time curve.
As shown in Table 5, control group 2,3, 4TmaxBoth 0.4 hr, control 1 and test 1-20TmaxAll have no significant difference in 0.4-0.8 hours. However, C, which indicates bioavailability, in the test group compared with the control groupmaxValues and AUC values increased 3-fold and 2-fold, respectively. Thus, this indicates that the bioavailability of the compounds of the present invention is significantly better than that of the control group.
