AI Technical Summary
Current treatments for inflammatory bowel disease (IBD) mainly focus on anti-inflammatory and symptomatic treatments, lacking radical cures, and there is an urgent need to find new therapeutic targets.
Develop a multi-TRP ion channel modulator that regulates calcium ion influx by inhibiting TRPV1, activating TRPM8 and TRPA1, inhibiting macrophage activation under inflammatory conditions, reducing the release of pro-inflammatory factors, promoting the release of anti-inflammatory factors, and alleviating intestinal inflammation and mucosal damage.
This modulator is more effective than TRPV1 inhibitors, TRPM8 agonists and TRPA1 agonists alone in treating intestinal inflammation. It significantly reduces intestinal inflammation and mucosal damage, lowers lactate dehydrogenase levels, and has little effect on biochemical and hepatic and renal function in mice. Moreover, the effect of enema administration is better than that of oral administration.

Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of medicine, in particular to a multi-TRP ion channel modulator and a preparation method and application thereof. BACKGROUND
[0002] Inflammatory bowel disease (IBD) is a chronic intestinal inflammatory disease with unknown etiology and recurrent attacks, including ulcerative colitis (UC) and Crohn's disease (CD). UC mainly involves the colorectum, and the lesion is limited to the mucosal layer and submucosal layer; CD has a jumping onset in the entire digestive tract, and the lesion range can involve the entire layer. The pathogenesis of IBD may be related to genetic factors, environmental factors, and mucosal immune disorders.
[0003] Transient receptor potential ion channels (TRP channels) are divided into six groups and 26 subtypes: TRPA1, TRPV (1-6), TRPM (1-8), TRPML (1-3), TRPC (1, 3-7), and TRPP (2, 3, 5). TRP channels are ligand-gated calcium-permeable non-selective cation channels and important temperature receptors. TRPV1, also known as capsaicin receptor and vanilloid receptor, can be activated by various physical and chemical stimuli, such as heat (temperature > 43℃), protons (pH < 5.9), etc. TRPM8 is a cold sensation receptor that can be activated by low temperature (< 28°C), pressure, and cold sensation compounds. TRPA1, also known as ANKTM1, is also a cold sensation receptor that can be activated by many aromatic substances. Currently, TRP channels are widely studied in the nervous system diseases and are considered as important drug targets for pain and peripheral neuritis.
[0004] Existing treatment methods are mainly anti-inflammatory and symptomatic treatment, and there is no effective method for radical cure of the disease. Therefore, it is urgent to find the potential pathogenesis of IBD through scientific research to find new therapeutic targets. SUMMARY
[0005] To solve the above technical problems, the present application develops a multi-TRP ion channel modulator that can inhibit TRPV1, activate TRPM8, and activate TRPA1, and the molecular structure is as follows (molecular weight: 827.95): .
[0006] Applicant's previous studies found that STW5, a European traditional plant preparation for treating functional gastrointestinal disorders, can modulate the activation and desensitization of intestinal primary sensory neurons TRPA1 and TRPV1 (PMID: 32682914); Menthacarin, a European traditional plant preparation for treating functional gastrointestinal disorders, can induce calcium influx and desensitization of macrophages, intestinal primary sensory neurons and colon organoids (PMID: 33127519). Further studies found that the cold sensation receptor TRPM8 can reduce the release of substance P in primary sensory neurons by regulating the binding of PKAca and GSK-3β, thereby inhibiting substance P-induced apoptosis of epithelial cells, reducing intestinal mucosal damage, and relieving intestinal inflammation. It is also clear that TRPM8 agonists (menthol) and substance P receptor antagonists (aprepitant) can be potential drug choices for intestinal inflammation and mucosal damage (PMID: 38280896); alcohol can exacerbate intestinal inflammation and induce macrophage M2b polarization through TRPV1-MAPK / NF-κB, and TRPV1 inhibitor capsaicin (CPZ) can be a potential drug choice for intestinal inflammation. CPZ has a certain activating effect on another TRP channel TRPA1 and has a potential therapeutic effect on intestinal inflammation (PMID: 38810558). Another study found that TRPV1 agonist alcohol can induce circulatory system microbial imbalance, leading to a significant increase in gram-negative bacteria and pro-inflammatory bacterial endotoxins in the body, damaging the colon epithelial barrier function, and exacerbating the occurrence and development of esophageal cancer (PMID: 40001134).
[0007] In summary, TRP ion channels, especially TRPV1, TRPM8 and TRPA1, have certain therapeutic effects on functional gastrointestinal disorders, intestinal mucosal damage, intestinal inflammation, immune disorders, dysbiosis, digestive tract tumors, pain, peripheral neuritis, etc.

[0108] 2) Calcium ion influx detection: Procedure: The macrophage cell line RAW264.7 cells were used for detection, and the stable cells were subcultured and cultured for 1 hour without serum. Then, the cells were loaded with Fluo-4 AM calcium ion influx reagent for 0.5 h. After removing the loading liquid, the cells were cultured in serum-free medium for half an hour and then subjected to experiment. The cells were stimulated with serum-free medium containing different stimulants. After each stimulation, the stimulant was replaced. The fluorescence intensity of the cells at 488 nm wavelength under different stimulations was recorded by microscope, which was the calcium ion influx intensity. The stimulants and concentrations were: multi-TRP ion channel modulator (Compound 1) 1 μM, CPZ 1 μM, Icilin 1 μM, Allylisothiocyanate (AITC) 1 μM, and combinations thereof.
[0109] Results: Figure 5 The fluorescence change pictures of the same macrophage cells under different stimulations are shown in A, and Figure 5 The fluorescence intensity change column chart is shown in B. It can be seen that the multi-TRP ion channel modulator can increase the calcium influx of the cells, and the calcium influx intensity after stimulation with CPZ+Icilin+AITC is similar. The calcium influx intensity after stimulation with Icilin+AITC is further increased, while CPZ+Icilin can decrease the calcium influx intensity of the cells. CPZ+AITC can increase the calcium influx intensity of the cells, but not as much as the multi-TRP ion channel modulator. The calcium influx intensity after stimulation with CPZ alone is the lowest. Icilin alone can increase the calcium influx intensity of the cells, but not as much as AITC.
[0110] In summary, the multi-TRP ion channel modulator has a regulatory effect on the calcium ion influx of the cells, and the effect is similar to that of the mixed stimulants of TRPV1 inhibitor CPZ, TRPM8 agonist Icilin, and TRPA1 agonist AITC.
[0111] II. Detection of cell function regulation as follows: 3) Activation of macrophage function pathway: Procedure: The macrophage cell line RAW264.7 cells were used for detection, and the stable cells were subcultured and cultured for 1 hour without serum. Then, the cells were loaded with Fluo-4 AM calcium ion influx reagent for 0.5 h. After removing the loading liquid, the cells were cultured in serum-free medium for half an hour and then subjected to experiment. The cells were stimulated with serum-free medium containing different stimulants. After each stimulation, the stimulant was replaced. The fluorescence intensity of the cells at 488 nm wavelength under different stimulations was recorded by microscope, which was the calcium ion influx intensity. The stimulants and concentrations were: multi-TRP ion channel modulator (Compound 1) 1 μM, CPZ 1 μM, Icilin 1 μM, Allylisothiocyanate (AITC) 1 μM, and combinations thereof.
[0112] Results: AsFigure 6 As shown in A, after stimulating the cells with multi-TRP ion channel modulator 100 nM / 1 μM / 10 μM, it was found that it had no obvious effect on the molecular level and phosphorylation level of NF-κB and p38 of normal cells. Further stimulation with LPS simulated the inflammatory state, and it was found that under the stimulation of LPS, multi-TRP ion channel modulator 100 nM / 1 μM / 10 μM could inhibit the molecular level and phosphorylation level of NF-κB, and inhibit the molecular level and phosphorylation level of p38, indicating that it had an inhibitory effect on the activation of macrophages in the inflammatory state. Next, by comparing the effects of multi-TRP ion channel modulator, CPZ, Icilin, and AITC under different stimulations, Figure 6 B found that: CPZ can significantly inhibit the phosphorylation of NF-κB of normal cells, affecting the function of normal cells, CPZ, Icilin, and AITC can significantly promote the phosphorylation of p38 of normal cells, affecting the function of normal cells, the combination of the three, AITC alone, and Icilin alone can significantly promote the phosphorylation of NF-κB and Erk1 / 2 of normal cells, affecting the function of normal cells; under the stimulation of LPS, the application of multi-TRP ion channel modulator, the combination of the three molecules, and CPZ can significantly inhibit the phosphorylation of NF-κB, inhibit the activation of macrophages in the inflammatory state, multi-TRP ion channel modulator and CPZ can significantly inhibit the phosphorylation of p38, inhibit the activation of macrophages in the inflammatory state, multi-TRP ion channel modulator, CPZ, and AITC can significantly inhibit the phosphorylation of Erk1 / 2, inhibit the activation of macrophages in the inflammatory state.
[0113] In summary, multi-concentration multi-TRP ion channel modulator has no obvious effect on normal macrophages, but can inhibit the activation of macrophages in the inflammatory state. Compared with CPZ, Icilin, and AITC, and their combinations, multi-TRP ion channel modulator has less effect on normal cells, but has similar inhibitory effect on the activation of macrophages in the inflammatory state.
[0114] 4) Macrophage inflammatory factor release: Process: Detecting the use of macrophage cell line RAW264.7Cells, cells stably passaged in culture were stimulated with LPS 1 μg / mL (mimic inflammatory state) and serum-free medium containing different stimulants for 6 h after serum-free culture for 1 h. The supernatant was collected and ELISA was performed to detect the concentrations of pro-inflammatory factors IL-1β, TNF-α, IL-23, IFN-γ, IL-12 and the concentration of anti-inflammatory factor IL-10. Stimulants and concentrations: multi-TRP ion channel modulator (Compound 1) 1 μM, CPZ 1 μM, Icilin 1 μM, Allyl isothiocyanate (AITC) 1 μM and the combination of CPZ, Icilin and AITC.
[0115] Results: As shown in Figure 7 , stimulation of multi-TRP ion channel modulator can significantly inhibit the release of other pro-inflammatory factors in macrophages under inflammatory state except IL-12, and significantly promote the release of anti-inflammatory factor IL-10. In contrast, CPZ mainly inhibits the release of IFN-γ, Icilin mainly inhibits the release of IL-1β and TNF-α, but promotes the release of IL-23, AITC mainly inhibits the release of IL-1β, TNF-α and IFN-γ, and promotes the release of IL-10, while the combination of the three promotes the release of IL-23.
[0116] In summary, multi-TRP ion channel modulator has an inhibitory effect on the release of major pro-inflammatory factors in macrophages under inflammatory state, and has a promoting effect on the release of anti-inflammatory factors, which is consistent with the respective effects of TRPV1 inhibitor CPZ, TRPM8 agonist Icilin and TRPA1 agonist AITC, but the effect is better than the combination of the three.
[0117] III. Animal experiments are as follows: 1) Regulation of intestinal inflammation: Procedure: Eight-week-old C57BL6 mice were used to model the disease. They were given 2.5% DSS in drinking water for 7 days, and their body weight was measured daily during this period. On the 8th day, the mice were sacrificed, and serum, colon length was measured, and the last 0.5 cm of rectum was taken for H&E staining. The indicators were compared. The administration methods were as follows: 100 μL of PBS solution containing 10 μM, 100 μM, and 1 mM of the multi-TRP ion channel modulator (Compound1) was administered orally, equivalent to 41.3975 μg / kg / day, 413.975 μg / kg / day, and 4.13975 mg / kg / day, respectively; 100 μL of PBS solution containing a mixture of 10 μM, 100 μM, and 1 mM of CPZ, Icilin, and AITC was administered orally, equivalent to CPZ 18.845 μg / kg / day, 188.45 μg / kg / day, and 1.8845 mg / kg / day; Icilin 15.5645 μg / kg / day, 155.645 μg / kg / day, and 1.55645 mg / kg / day, respectively; AITC 4.9575 μg / kg / d, 49.575 μg / kg / d, 495.75 μg / kg / d; 100 μL of PBS solution containing 10 μM of multi-TRP ion channel modulator (Compound1) was administered via enema, which is equivalent to 41.3975 μg / kg / d.
[0118] Result: As Figure 8 As shown in the AE, the control group of the enteritis mouse model exhibited the most severe intestinal inflammation and mucosal damage, with the most significant colonic shortening. In the treatment groups, the 1mM multi-TRP ion channel modulator and the 1mM mixture of CPZ, Icilin, and AITC showed the best therapeutic effects, with the 100μM multi-TRP ion channel modulator showing similar efficacy. Furthermore, compared to the 100μM mixture of CPZ, Icilin, and AITC, it resulted in less mucosal damage. Figure 8 (BD). It is worth noting that an enema of 10 μM of multi-TRP ion channel modulators can achieve similar therapeutic effects as an oral administration of 1 mM of multi-TRP ion channel modulators. Figure 8 BD).
[0119] In summary, the therapeutic effect of multi-TRP ion channel modulators on intestinal inflammation and mucosal damage in mice is slightly better than the combined application of TRPV1 inhibitor CPZ, TRPM8 agonist Icilin, and TRPA1 agonist AITC, and the effect of multi-TRP ion channel modulators via enema is better than that via oral administration.
[0120] 2) Mouse toxicity test: Procedure: After the mice in the control group and the groups orally administered with the multi-TRP ion channel modulator (Compound 1) at 10 μM, 100 μM and 1 mM were sacrificed, the serum was subjected to biochemical, liver function, kidney function, blood lipid and other index determination, and the liver and kidney were subjected to H&E staining for comprehensive evaluation of drug toxicity.
[0121] Results: The liver and kidney staining results are shown in Figure 9 A, and no obvious difference was observed between the groups. The biochemical, liver function, kidney function, blood lipid and other results are shown in Figure 9 B, and some inflammation and damage related indexes were relieved in the administration groups. As shown in Figure 9 C, it was found through comparison that the total protein and albumin amount in the 1 mM group was obviously improved, the total bilirubin was slightly reduced in the 1 mM group, which might be caused by anemia due to intestinal inflammation and bleeding, the alkaline phosphatase was slightly increased in the 100 μM and 1 mM groups, the lactate dehydrogenase was obviously higher in the control group than in the administration groups, which also reflected the reduction of inflammation and tissue damage, the total bile acid was slightly increased in the 100 μM and 1 mM groups, which could also be explained by anemia caused by the aggravation of intestinal inflammation in other groups, and there was no obvious difference in other indexes.
[0122] In summary, the multi-TRP ion channel modulator has little effect on the biochemical, liver function, kidney function, blood lipid and other indexes of mice, slightly affects the metabolism of bile acid and bilirubin, and can obviously reduce the level of lactate dehydrogenase.
