Description

Transmucosal administration agent containing a compound having a phenylpyrazole skeleton that acts on the circadian clock protein CRY

[0001] The present invention relates to a transmucosally ingestible agent and the like.

[0002] The clock protein CRY plays a central role in the oscillation of the circadian clock and is a causative gene for human sleep rhythm disorders. Furthermore, Cry gene knockout mice show abnormalities in glucose metabolism. Therefore, CRY is expected to be a drug discovery target for sleep rhythm disorders and glucose metabolism disorders.

[0003] The carbazole derivative KL001 was reported as the world's first synthetic compound acting on CRY. KL001 interacts with both CRY1 and CRY2, which are closely related isoforms, and inhibits CRY degradation via the ubiquitin ligase FBXL3, thereby activating CRY function and extending the circadian rhythm at the cellular and tissue levels. Furthermore, KL001 inhibits glucagon-stimulated gluconeogenesis in primary cultured mouse hepatocytes. Furthermore, an orally available KL001 derivative has been developed and has been reported to improve glucose intolerance in diet-induced and genetically obese mouse models (Non-Patent Document 1, Patent Document 1, Patent Document 2). This derivative (SHP656) exhibits selectivity for CRY2.

[0004] Furthermore, phenylpyrazole derivatives have been reported as compounds that selectively activate CRY1 and CRY2 (Non-Patent Document 2).

After treatment, measurements were continued for another 2 weeks in constant darkness. Experiments using Cry1 KO and Cry2 KO mice were performed similarly, with treatment at ZT19 and subsequent measurements after treatment. Since the Cry1 KO mouse has a cycle approximately 70 minutes shorter than the wild-type mouse, the administration time was adjusted to be 70 minutes earlier each day. On the other hand, since the Cry2 KO mouse has a cycle approximately 50 minutes longer than the wild-type mouse, the administration time was adjusted to be 50 minutes later each day. The behavioral rhythm period was calculated using the analysis software ActogramJ.

[0093] Analysis of glucose tolerance in obese model mice: Male C57BL / 6J mice were fed a high-fat diet to create obese model mice. TH139, TH301, or control DMSO suspended in 1% Metolose was orally administered at 100 mg / kg once daily on ZT1 (1 hour after the onset of the light phase). Before and after the 1-week or 4-week treatment period, the mice were fasted for 16 hours and then subjected to glucose tolerance tests by intraperitoneal administration of a glucose solution.

[0094] (1-2) Test results We analyzed the pharmacokinetics of CRY1-selective KL101 and CRY2-selective TH301 in individual mice (Figure 1). TH301 maintained a blood concentration of 1 μM or higher for more than 4 hours after oral administration, suggesting that it could be used directly for in vivo experiments. On the other hand, KL101 exhibited very low blood concentrations, indicating that further modification was necessary for in vivo experiments.

[0095] KL101 and TH301 are both phenylpyrazole derivatives with similar structures (Figure 2). Because the upper portion of these molecules plays an important role in isoform selectivity (Miller, S. et al. Structural differences in the FAD-binding pockets and lid loops of mammalian CRY1 and CRY2 for isoform-selective regulation. Proc Natl Acad Sci USA 118, e2026191118 (2021)). Therefore, we obtained TH139 (Figure 2), a molecule in which the lower portion of KL101 was replaced with TH301, and analyzed its effects. In human U2OS cells, TH139 extended the circadian rhythm period of the Bmal1-dLuc reporter, similar to KL101 (Figure 3). Furthermore, TH139 inhibited the degradation of the CRY1-LUC reporter, increasing its half-life, while having little effect on the half-life of the CRY2-LUC reporter (U2OS cells: Figure 4; HEK293 cells: Figure 5). TH139 also exhibited a similar effect to KL101 in mouse fibroblasts (Figure 6). Because CRY is a transcriptional repressor of the Per2 gene, activation of CRY reduces the Per2::Luc reporter. While TH139 repressed the Per2::Luc reporter in wild-type cells containing both CRY1 and CRY2 (Figure 6, top left), the repression effect was attenuated in Cry1 KO cells lacking CRY1 (Figure 6, bottom left). On the other hand, the repression effect was maintained in Cry2 KO cells lacking CRY2 (Figure 6, bottom right), and was abolished in Cry1 / Cry2 KO cells lacking both CRY1 and CRY2 (Figure 6, top right). These results demonstrate that TH139 selectively activates CRY1.

[0096] Next, we analyzed the pharmacokinetics of TH139 in mice (Figure 7). After oral administration of 50 mg / kg, TH139 maintained a blood concentration of 1 μM or higher for more than 4 hours, suggesting its suitability for in vivo experiments. Following oral administration of 100 mg / kg, both TH139 and TH301 maintained blood concentrations of 10 μM or higher for more than 4 hours. Because the brain is protected by the blood-brain barrier, most compounds in the blood cannot reach the brain. The suprachiasmatic nucleus controls the behavioral rhythm of sleep and wakefulness, and compounds must reach the brain to control behavioral rhythms. Meanwhile, gluconeogenesis is primarily carried out in the liver. After oral administration, we measured the concentrations of TH139 and TH301 in the brain and liver and found that they were present in both tissues at concentrations equal to or higher than those in the blood (Figure 8). Thus, oral administration of TH139 and TH301 is expected to selectively activate CRY1 and CRY2 functions in various tissues, including the brain and liver.

[0097] To treat sleep rhythm disorders, we attempted to control behavioral rhythms in mice. CRY protein activity exhibits a circadian rhythm, increasing in daytime activity in the suprachiasmatic nucleus (SNU) beginning at ZT7 (7 hours after the onset of the light period) and decreasing in the middle of the night beginning at ZT19 (7 hours after the onset of the dark period). Pharmacokinetic analysis indicated that the plasma concentrations of both TH139 and TH301 significantly decreased approximately 8 hours after oral administration, suggesting that their effects could not be maintained for 24 hours. Therefore, we compared the effects of TH139 and TH301 at ZT7 and ZT19. Wild-type mice were orally administered 50 mg / kg of TH301 once daily under constant darkness for 2 weeks, and behavioral rhythms were measured (Figure 9). Administration at ZT7 did not affect the circadian period, but administration at ZT19 prolonged the period, and the period-prolonging effect disappeared upon discontinuation of administration. Thus, activation of CRY2 by TH301 successfully controlled behavioral rhythms in a time-of-day and reversible manner. The period-lengthening effect observed at ZT19, when CRY activity begins to decline, is consistent with the mechanism of action of TH301 activating CRY2. Similarly, CRY1 activation by oral administration of 50 mg / kg TH139 also altered the period of behavioral rhythms in a time-of-day-dependent and reversible manner (Fig. 10). Only TH301 significantly lengthened the period in Cry1 KO mice, and only TH139 significantly lengthened the period in Cry2 KO mice (Fig. 11), demonstrating that these compounds exhibit isoform selectivity even at the individual level.

[0098] Furthermore, we attempted to control blood glucose levels in mice with the aim of applying this to diabetes treatment. Mice fed a high-fat diet became obese and showed impaired glucose tolerance. 100 mg / kg of TH139 or TH301 was orally administered once daily for four weeks to these obese model mice, and the effects on glucose tolerance were analyzed (Figure 12). The administration time was ZT1, at which CRY activity in the liver begins to decrease. While administration of the control DMSO worsened glucose intolerance within four weeks, administration of TH139 and TH301 prevented this deterioration. Furthermore, oral administration of 100 mg / kg of TH139 for one week after glucose intolerance had progressed was effective in improving glucose intolerance (Figure 13).

[0099] Previous studies have suggested that compounds selective for CRY2 are effective in treating impaired glucose tolerance. The results above indicate that not only CRY2-selective activation but also CRY1-selective activation is effective in treating impaired glucose tolerance.

[0100] Test Example 2 (2-1) Materials and Methods Acquisition of Compounds: TH320 was purchased from ChemDiv (K410-0861). TH321 was purchased from Life Chemicals (F0561-0620). Analysis of Circadian Rhythms in Human U2OS Cells: The method described in Non-Patent Document 2 was used. Analysis of CRY Degradation in Human HEK293 Cells: The method described in Non-Patent Document 2 was used. Analysis of Circadian Rhythms in Cry1 / Cry2 Knockout Mouse Fibroblasts Rescued from Cry: The method described in Non-Patent Document 2 was used. Crystal Structure Analysis of CRY1: The method described in Non-Patent Document 2 was used. (2-2) Test Results TH301 has two oxygen atoms bound to the sulfur atom, whereas KL101 has no oxygen atom bound to the sulfur atom (Figure 2). To clarify the effect of these oxygen atoms on the activity of the compounds, TH320 with two oxygen atoms bound and TH321 with one oxygen atom bound (Figure 14) were obtained and analyzed. In human U2OS cells, TH321 extended the circadian rhythm of the Bmal1-dLuc reporter slightly more strongly than KL101, whereas TH320 extended it approximately 10-fold more strongly (Fig. 15). Furthermore, TH320 also enhanced the inhibition of CRY1-LUC reporter degradation and increased its half-life (Fig. 16). In Cry1 / Cry2 knockout mouse fibroblasts in which CRY1 or CRY2 was rescued, TH320 exhibited a more potent and selective effect on CRY1 than KL101 (Fig. 17). These results suggest that the activity of KL101 increases depending on the number of oxygen atoms bound to the sulfur atom. To clarify the molecular mechanism, we performed X-ray crystallography of CRY1 bound to TH320 and TH321. As a result, three water molecules (W1, W2, and W3) were found near S in the compounds, and in TH320, two O atoms bound to S interacted with W1 and W3, respectively (Fig. 18), while in TH321, one O atom bound to S interacted with W3 (Fig. 19). On the other hand, although W1-W3 were present in the CRY1-KL101 complex described in Non-Patent Document 2, no interaction with KL101 was observed (Fig. 20).W1, W2, and W3 form a strong hydrogen-bond network with serine 252 (S252), arginine 293 (R293), aspartic acid 387 (D387), and aspartic acid 389 (D389) of CRY1, and it is thought that TH320 and TH321 increase the activity by interacting with this network via O. These results suggest an effective means to increase the activity of KL101, a compound selective for CRY1.
