Definitions
- the present invention relates to a therapeutic agent for Parkinson's disease and the like.
- the present invention also relates to novel compounds useful as therapeutic agents for Parkinson's disease and the like.
- Parkinson's disease It is said that more than 100,000 patients with Parkinson's disease exist in Japan, but the current drug therapy is mainly symptomatic therapy represented by dopamine replacement therapy. It is considered that the cause of Parkinson's disease is a lack of dopamine due to a decrease in nerve cells that produce dopamine, but there is no one on the market as a fundamental therapeutic agent. Therefore, it is desired to develop a drug that can be a fundamental therapeutic drug for Parkinson's disease. In addition, such a fundamental therapeutic agent for Parkinson's disease is expected to be utilized in the treatment of Parkinson's syndrome which exhibits the same symptoms as those in Parkinson's disease.
- meloxicam which is an oxicam non-steroidal anti-inflammatory drug, has been reported to exhibit an MPP + -induced neuronal cell death inhibitory effect and a motor dysfunction reducing effect in MPTP-administered Parkinson's disease model mice (Non-Patent Documents 1 to 3). .. Therefore, meloxicam is considered to be a candidate drug such as a therapeutic drug for Parkinson's disease, but it also has a problem. For example, meloxicam has a strong COX inhibitory activity and causes side effects such as gastrointestinal disorders, so it is not desirable as a therapeutic agent for Parkinson's disease and the like.
- a novel therapeutic agent for Parkinson's disease which can be a fundamental therapeutic agent for Parkinson's disease.
- a therapeutic agent for Parkinson's disease may be useful as a therapeutic agent for Parkinson's syndrome or a pharmaceutical agent for protecting nerve cells.

- meloxicam was used instead of the evaluation compound, and the same evaluation was performed. The results are shown in Table 1 below. The meloxicam had a very strong COX-2 inhibitory activity, whereas the compounds evaluated had a lower COX-2 inhibitory activity than meloxicam.
- COX-2 inhibitory activity is significantly weaker than that of meloxicam
- COX-2 of IY-091, IY-092, IY-093, IY-094, IY-101, IY-102, IY-103 and IY-104 No inhibitory activity was detected.
- Example 27 Evaluation of protective effect against MPP + -induced cultured neuronal cell death
- MPP + (1-methyl-4-phenylpyridinium
- DMEM Dulbecco's modified Eagle medium
- SIGMA penicillin (100 U/mL) streptomycin (100 ⁇ g/mL).
- Example 28 Evaluation of drug efficacy using MPTP-induced Parkinson's disease model mouse MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine)-induced Parkinson's disease model for drug efficacy evaluation of many therapeutic drugs for Parkinson's disease
- the mouse is being used.
- the model mouse can be used to evaluate the drug efficacy dose and the safety.
- MPTP-induced Parkinson's disease model mice were used to evaluate the improving effect of the evaluated compounds on experimental Parkinsonism by the Pole test method.
- the mice and samples used are as follows. ⁇ Mice: Male C57BL/6 mice (SLC, 9 weeks old at the start of administration, 11 weeks old at the time of behavior evaluation, 20-25 g) Acclimatized for 7 days after arrival.
- ⁇ MPTP 30 mg/kg subcutaneously administered to mice (dissolved in Saline)
- -Evaluation compound Intraperitoneally or orally administered to mice at 3, 7.5, 10, 20 or 30 mg/kg (dissolved in 0.5% CMC)
- ⁇ Meloxicam reference example: Intraperitoneally administered to mice at 10 mg/kg (dissolved in Saline) The administration was performed by grouping as follows.
- ⁇ Control group CMC twice daily intraperitoneal administration (morning and evening) for 15 days, Saline once daily subcutaneous administration (daytime) for the first 5 days
- MPTP group CMC twice daily intraperitoneal administration (morning and evening) 15 days
- MPTP + evaluation compound group Evaluation compound once or twice daily intraperitoneally or orally (10 mg administration once in the morning, or 3, 7.5, 10 , 20 or 30 mg once a day in the morning and evening) 15 days, MPTP 30 mg/kg once a day subcutaneously (day)
- MPTP + meloxicam group meloxicam once a day intraperitoneally (once day) 10 mg administration) 15 days
- IY-027, IY-053, IY-060, IY-065, IY-067, IY-068, IY-069, and IY-093 are used in consideration of the measurement results of neuronal cell protective effect.
- IY-027 was intraperitoneally administered, and the others were orally administered to mice.
- the Pole test was performed as follows. Before the administration on the 15th day, the mouse was grasped upward by the tip of a rod having a diameter of 8 mm and a height of 55 cm, and the time from the beginning of movement until the mouse turned completely downward was defined as T turn . The longer this time is, the greater the degree of movement disorder is.
- Each mouse was acclimated once, and the same measurement was performed 5 times per mouse, and the average value was used. The results are shown in FIGS.
- Each of the compounds to be evaluated shortened the T turn lengthened by the administration of MPTP to the same extent as the control group not administered with MPTP. Thus, it was shown that any of the evaluated compounds improved the movement disorder.
- a significant difference was observed between the MPTP group and the MPTP+evaluated compound group (IY-027, IY-053, IY-060, IY-093) at a significance level of 0.1%.
- a significant difference was observed between the MPTP group and the MPTP+assessed compound group (IY-067) at the 1% significance level.
- Example 29 Measurement of plasma and brain concentrations
- the mice and samples used are as follows. ⁇ Mouse: Male C57BL/6 mouse (self breeding, 22-30 g) Evaluation compound: 10 mg/kg (dissolved in 0.5% CMC) 1, 4 and 8 hours after oral or intraperitoneal administration of the compound to be evaluated, blood was collected from the inferior vena cava using a 26G injection needle + 1 mL syringe anesthetized and heparinized, and the microcooled centrifuge (KUBOTA3780 was cooled to 4°C. ) was centrifuged at 5000 rpm for 5 minutes, and the supernatant was used as plasma. Next, the whole brain was taken out and the brain weight was measured.
- KUBOTA3780 was cooled to 4°C.
- a bead crusher bead crusher ⁇ T-12
- the compound in which -XY- represents -CR 4 R 5 -CR 6 R 7- has higher intracerebral transferability (brain/plasma concentration ratio) than meloxicam, but its plasma concentration is It was low and tended to decrease rapidly with time.
- the compound in which -XY- represents -CR 4 R 5 -SO 2- showed a high concentration in the brain, and had higher intracerebral transferability (brain/plasma concentration ratio) than meloxicam.
- the other evaluated compounds behaved similarly to meloxicam.
- the results of using IY-027 manufactured in Example 1, using IY-065, and using IY-093 are shown in Table 2 below.
- the lower limit of quantification of plasma concentration was 0.003 ⁇ M
- the lower limit of quantification of brain concentration was 0.012 nmol/g
- the lower limit of quantification of plasma concentration was 0.01 ⁇ M
- the lower limit of quantification is 0.04 nmol/g.
- the lower limit of quantification of plasma concentration is 0.1 ⁇ M
- the lower limit of quantification of brain concentration is 1.0 nmol/g.
- the compound of the present invention has a neuronal cell protective effect and improves motor disorders in Parkinson's disease model mice, and thus may be useful as a therapeutic agent for Parkinson's disease. It is considered that the compound of the present invention can suppress the progression of Parkinson's disease and stop the progression thereof. In addition, the compound of the present invention is considered to be applicable to the treatment of Parkinson's syndrome which exhibits the same symptoms as those in Parkinson's disease. Since the existing drugs bromocriptine, levodopa, and dopamine itself do not have a protective effect on MPP + -induced neuronal cell death, the compounds of the present invention have utility over these existing drugs for the treatment of Parkinson's disease and the like. I will get it.
- oral administration of the compound of the present invention markedly improves the movement disorder of Parkinson's disease model mice, and no remarkable toxicity is observed in the mice, and therefore, it can be easily taken and can contribute to improvement of QOL of patients.
- the compounds of the present invention are less likely to cause gastrointestinal disorders and may be more useful because of their lower COX inhibitory activity compared to meloxicam.
