Patent Application
20230087342
The present invention relates to an azepane derivative having a κ opioid receptor agonistic effect.
The present application claims priority based on JP 2019-179727 A filed in Japan on Sep. 30, 2019, the content of which is incorporated herein by reference.
Three types of opioid receptors are known: μ, δ, and κ. Morphine, which exhibits a high affinity for μ opioid receptors, has been used as an analgesic for a long time. However, μ opioid receptor agonists such as morphine are known to cause adverse events such as dependence and respiratory depression via μ opioid receptors.
Meanwhile, κ opioid receptor agonists are also known to exhibit an analgesic effect, but are not involved in such adverse events caused by morphine.
On the other hand, it is known that κ opioid receptor agonists generally exhibit a sedative effect and a drug-aversion effect. The only κ opioid receptor agonist from which drug-aversion has been separated is Nalfurafine (Patent Literature 1). However, since Nalfurafine exhibits a sedative effect in an analgesic dose, it has been approved as an antipruritic drug, but has not been approved as an analgesic. That is, there is still no κ opioid receptor-selective agonist approved as an analgesic.
Accordingly, a κ opioid receptor-selective agonist not exhibiting a sedative effect or a drug-aversion effect is expected as an excellent treating, improving or preventing drug for diseases or symptoms related to κ opioid receptors such as an analgesic.
Patent Literature 2 discloses that a compound represented by the following formula (A):
has a κ opioid receptor agonistic activity. However, the activity is not sufficient.
Furthermore, Patent Literature 3 reports a compound represented by the following formula (B):
It is described that this compound has a κ opioid receptor selective binding effect and an analgesic effect. However, the analgesic activity is far from satisfactory.
In addition, Patent Literature 4 and Non Patent Literature 1 disclose that a compound (C) represented by the following formula:
has extremely high activity. However, the compound has had insufficient in vivo stability. When the compound is unstable in vivo, it is difficult to develop the compound as a pharmaceutical product due to the fact that expected drug efficacy is not exhibited, the influence of the decomposed product is exerted on the living body, and the like. Accordingly, in vivo stability is an important requirement in the development of pharmaceutical products.
Among analgesics on the market, there is still no drug having high κ opioid receptor agonist activity.
Therefore, in order to aim for an analgesic, a compound is desired that exhibits selectivity and high activity for κ opioid receptors, is excellent in in vivo stability, and has little sedative effect and drug-aversion effect.
An object of the present invention is to provide a medicine effective for treatment, improvement, or prevention of various diseases and symptoms related to κ opioid receptors, in which the sedative effect and the drug-aversion effect are suppressed.
Under such circumstances, as a result of intensive studies, the present inventors have found that a specific azepane derivative exhibits potent agonist activity against κ opioid receptors and high in vivo stability. Furthermore, it has been revealed that the present azepane derivative exhibits a potent analgesic effect, and does not exhibit a sedative effect even at a dose higher than that of Nalfurafine (Patent Literature 1). As described above, the present inventors have found an azepane derivative that is a highly safe κ opioid receptor agonist intended for an analgesic, and completed the present invention.

1)A hydrochloride was used.
As shown in Table 3, the compound of the present invention exhibits excellent metabolic stability.
Mouse Acetic Acid Writhing Test
The analgesic effect of the test compound was evaluated by an acetic acid writhing test. For the experiment, ICR male mice were used and acclimated to a plastic open field for 30 minutes before starting the test. After acclimation, the mice were administered with the test compound (30 to 3000 μg/kg) or water for injection subcutaneously or orally, and once returned to the open field. Thirty minutes after the administration of the test compound, a 0.6% aqueous acetic acid solution was additionally administered to the same mice by intraperitoneal administration. From 10 minutes after administration of the 0.6% aqueous acetic acid solution, the number of writhing reactions (writhing reactions in which the mouse stretches while pressing the abdominal cavity against the floor) induced in the mice was measured for 10 minutes, and the number of writhing reactions was compared with that of a control group (water for injection-administrated group) to evaluate the analgesic effect of the test compound. The results are shown in Table 4.
1)A hydrochloride was used.
2)The writhing suppressing effect was classified as follows according to the suppression rate.
3)N.C.: not calculated
As shown in Table 4, it has been confirmed that the compound of the present invention exhibits a potent analgesic effect.
Rotarod Test
The sedative effect (motor coordination disorder effect) of the test compound was evaluated by a rotarod test. For the experiment, ICR male mice that had learned a motion task in advance by rotarod training were used. Rotarod training was repeated while providing a moderate rest period until the mice acclimatized for 60 seconds on a rotating shaft rod rotating at 3 rpm (diameter 3 cm, KN-75, Natsume Seisakusho Co., Ltd.) and acquired motor learning. Thereafter, a total of three training units of 3 rpm for 180 seconds, 4 rpm for 180 seconds, and 5 rpm for 180 seconds were provided. After all training, a 90 to 120 minute rest was provided to reduce the burden on the mice. A mouse that failed to acquire motor learning by training was not used for the experiment.
In the rotarod test, the number of times of falling at 5 rpm for 300 seconds (cut-off value 300 seconds) was measured as a pre-value before administration of the test compound. After the measurement of the pre-value, the mice were treated with the test compound (3 to 500 μg/kg) or water for injection by subcutaneous administration (s.c.) or oral administration (p.o.), and the number of times of falling at 5 rpm for 300 seconds was measured at each of four points of 30 minutes, 60 minutes, 90 minutes, and 120 minutes after administration of the test compound, in the same manner as measurement of the pre-value. The total number of times of falling at the four points was defined as the total number of times of falling (total falls), and the sedative effect of the test compound was evaluated. The results are shown in
