Abstract
Description
[Technical Field]
[0001] The present invention relates to pharmaceutical compositions of the compound of formula (I) or its stereoisomers, pharmaceutically acceptable salts and pharmaceutical formulations thereof, and their application in the manufacture of medicaments for treating diseases associated with inhibitors that inhibit AAK1. [Background technology]
[0002] Neuropathic pain (NP) is a general term for a range of pain caused by damage or disease of the somatosensory nervous system and can be divided into peripherally-induced neuropathic pain (pNP) and central neuropathic pain. Clinically, pNP is more common and can be specifically divided into diabetic peripheral neuralgia, postherpetic neuralgia, trigeminal neuralgia, and chronic postoperative neuralgia. Patients with pNP often experience symptoms such as spontaneous pain (pain without any external stimulus), allodynia (increased response to painful stimuli), hyperalgesia (pain in response to normally non-painful stimuli), and paresthesia, which significantly impact the patient's quality of life.
[0003] AAK1 is a member of the Ark1 / Prk1 family of serine / threonine kinases and is widely expressed in the brain and spinal cord. Studies have shown that AAK1 gene knockout mice are endowed with persistent pain or hypoalgesia responses, and do not develop allodynia in a spinal nerve ligation neuropathic pain model, demonstrating that AAK1 is a viable target for the treatment of pNP.

[0153] Example 4: hERG potassium ion channel activity test Experimental platform: electrophysiological manual patch clamp system Cell line: Chinese hamster ovary (CHO) cell line stably expressing hERG potassium ion channel Experimental Method: hERG potassium channel currents were recorded at room temperature using the whole-cell patch clamp technique in CHO (Chinese Hamster Ovary) cells stably expressing the hERG potassium channel. Glass microelectrodes were fabricated by pulling glass electrode blanks with a BF150-86-10 Sutter puller. After filling the electrode with internal solution, the tip resistance was approximately 2-5 MΩ. The glass microelectrode was then inserted into the amplifier probe for connection to the patch clamp amplifier. Voltage clamping and data recording were computer-controlled using pClamp 10 software. The sampling frequency was 10 kHz and the filtering frequency was 2 kHz. After whole-cell recording, the cells were clamped to -80 mV, and a step voltage was applied to elicit the hERG potassium current (I hERG) by depolarizing from -80 mV for 2 s to +20 mV, repolarizing to -50 mV for 1 s, and then returning to -80 mV. The stimulation was repeated every 10 s, and the hERG potassium current was allowed to stabilize (for at least 1 min) before the administration process began. Compounds were administered for at least 1 min per test concentration, and at least two cells were tested for each concentration (n ≥ 2).
[0154] Data processing: Data analysis and processing were performed using pClamp 10, GraphPad Prism 5, and Excel software. The inhibition of hERG potassium current (peak hERG tail current evoked at -50 mV) by different compound concentrations was calculated using the following formula:
[0155] Inhibition%=[1‐(I / Io)]×100% Here, Inhibition% represents the percentage of inhibition of the hERG potassium current by the compound, and I and Io represent the amplitude of the hERG potassium current after administration and before administration, respectively.
[0156] Compound IC50 was calculated by fitting the following equation using GraphPad Prism 5 software:
[0157] Y=Bottom+(Top-Bottom) / (1+10^((LogIC50-X)×HillSlope)) where X is the Log value of the sample detection concentration, Y is the percentage inhibition at the corresponding concentration, and Bottom and Top are the minimum and maximum percentage inhibition, respectively.
[0158] Experimental results: The IC50 values of the test compounds for the inhibitory effect on the hERG potassium channel are shown in Table 4.
[0159] [Table 4]
[0160] Example 5: Spinal nerve ligation (SNL)-induced neuralgia model in mice Male C57BL / 6J mice (8 weeks old) purchased from Jinan Pengyue Experimental Animal Breeding Co., Ltd. were acclimatized and raised for one week before being used to create the model. The specific preparation method is as follows: 1) Disinfect surgical instruments and ligatures, 2) Anesthetize the mouse with isoflurane and place it in the prone position on the operating table. 3) Cut the mouse's hair near the hipbone, disinfect the skin, and make an incision approximately 2 cm long along the spine. 4) Separate the fascia along the spine and bluntly separate the muscles to expose the L5 transverse process. 5) Using forceps, carefully bite off the L5 transverse process to expose the L5 spinal nerve. 6) Carefully separate the L5 nerve using a glass separation needle and ligate the L5 nerve with a 5-0 ligature. 7) The muscles and skin are sutured and disinfected with iodophor. The day after model creation, mice that were not successfully created were removed (signs of successful model creation: the mouse's hind legs were curled). After model creation, mice were stroked for 3-5 minutes every day to allow the animals to become accustomed to the experimenter, and then placed on a metal pain measurement frame for 40-60 minutes of adaptation. After environmental adaptation was completed on the third day, Von Frey filaments (Aesthesio) were used. (R) The animals were tested for baseline values (Ascending test) using 0.16, 0.4, 0.6, 1.0, 1.4, and 2.0 grams (0.16, 0.4, 0.6, 1.0, 1.4, and 2.0 grams). Each animal was measured twice, with at least 5 minutes between measurements, and the average was calculated. The animals were grouped according to their baseline values (10 animals per group). After grouping, LX-9211 (1 and 10 mg / kg), Compound 2 (1 and 10 mg / kg), or vehicle (40% PEG-400 + 10% ethanol + 15% Tween 80 + 35% saline) was administered orally by gavage, and the mechanical pain threshold (MPT) of the mice was tested 1, 3, and 6 hours after administration. Time-MPT curves were plotted and statistical analysis was performed using GraphPad 8.3.0.
[0161] Results and Conclusions: The results are shown in Figure 1. At 1, 3, and 6 hours after a single administration, both 10 mg / kg LX-9211 and Compound 2 effectively increased the pain threshold of SNL model mice. The analgesic effect of 10 mg / kg LX-9211 peaked at 1 hour after administration and gradually decreased thereafter. However, the analgesic effect of 10 mg / kg Compound 2 peaked at 3 hours after administration and remained stable from 1 to 6 hours, demonstrating superior efficacy at 3 and 6 hours after administration. These data suggest that the analgesic activity of Compound 2 is superior to that of LX-9211.

[0164] [Table 5] NOTE: Vehicle for oral gavage: 40% PEG-400 + 10% Ethanol + 15% Tween 80 + 35% Saline; (Saline: physiological saline, Ethanol: ethanol, Tween 80: Tween 80)
[0165] After oral gavage, whole blood and brain tissue were collected at 0.5, 4, and 24 h. The whole blood was centrifuged to separate the plasma. The brain tissue was washed with cold saline to remove any remaining blood, then suction-dried and homogenized. All samples were stored at -80°C before analytical detection. Quantitative analysis of the samples was performed using LC-MS / MS.

[0175] [Table 9]
[0176] Tablets of the composition containing Compound 3 were prepared according to the formula in the table. First, Compound 3 was mixed with a wetting agent by sieving five times, then mixed in a mixer for 15 minutes, then a diluent and a disintegrant were added and mixed for 15 minutes, and finally a lubricant was added and mixed for another 3 minutes to obtain a composition containing Compound 3. The composition was then compressed into tablets using a tablet press.
[0177] The present inventors have observed whether the above formulation causes the composition to aggregate or stick to equipment due to the softening or melting of Compound 3 during the process, and have also investigated the content uniformity of the finished product.
[0178] [Table 10]
[0179] Conclusion: Adding a certain amount of wetting agent in the formulation significantly improved the softening / melting phenomenon that occurred during the preparation of compound 3, and the content uniformity of the tablets was good. 7.3 Prescriptions 13-18
[0180] [Table 11]
[0181] Preparation method: Compound 3 and a wetting agent were mixed in a mixer for 15 minutes, then a diluent and a disintegrant were added and mixed for 15 minutes, and finally magnesium stearate was added and mixed for 3 minutes to obtain a composition containing Compound 3.
