Abstract
Description
[Technical Field]
[0001] This invention belongs to the field of medicinal chemistry and specifically relates to a breiaconitine A derivative having analgesic activity, a method for preparing the same, and its use. [Background technology]
[0002] Pain is one of the diseases that harm human health. Chronic pain, also known as "non-dead cancer," has a serious impact on people's physical and mental health and quality of life, and is a major challenge in the global health field.
[0003] Bulleaconitine A, also known as crude uberlotin, is a C19-diterpenoid alkaloid distributed in most plants of the genus Aconitum, primarily found in Citropira (Aconitum L. bulleyanum Diels), a plant of the genus Aconitum. In 1986, scientists confirmed the analgesic effect of bulleaconitine A using the rising method, hot plate method, photothermal feeding method, and formaldehyde seizure method, and developed it as a clinical drug. Currently available dosage forms include tablets, capsules, pills, and injections. Oxalistatin has good analgesic, anti-inflammatory, and immunosuppressive effects and is widely used to treat various chronic pains such as rheumatoid arthritis, osteoarthritis, neuropathic pain, herpes zoster pain, shoulder pain, lumbar sprains, sprains, cancer pain, and postoperative pain. Furthermore, it can alleviate inflammatory responses such as redness, emphysema, and fever associated with rheumatoid arthritis and rheumatoid arthritis. Its non-dependency, drug tolerance, and gastrointestinal reactions result in significantly lower toxicity and side effects compared to opioids and nonsteroidal anti-inflammatory drugs, making it highly suitable for patients requiring long-term pain relief. In 2013, bryaconitine A was incorporated into the "Expert Consensus on Neuropathic Pain Management," demonstrating its important role in treating chronic pain caused by various factors. [ka] Braiaconitine A
[0004] Breiaconitine A is a non-addictive, non-opioid herbal analgesic with advantages such as high analgesic efficacy, long duration of action, and no dependence. However, it has a narrow safety margin and high acute toxicity, causing transient mild panic, nausea, numbness of the lips and tongue, and palpitations during use. Regarding the presentation of animal toxicity literature, the toxicity of the biester alkaloids contained in breiaconitine A is mainly to the nervous system (especially the vagus nerve and sensory nerves), and it also acts directly on the myocardium, potentially leading to death through respiration or myocardial paralysis. Therefore, developing new derivatives of breiaconitine A that have high biological activity and low toxicity is of great significance for the clinical application of analgesics.

[0140] The beneficial effects of the present invention will be demonstrated below through experimental examples.
[0141] Experimental Example 1: Anti-inflammatory and analgesic activity and toxicity test of the compound of the present invention 1. Laboratory animals and samples Test animals: Kunming mice (half male and half female; weight 22±2g) provided by Chengdu Dashuo Laboratory Animals Co., Ltd. The mice were housed in the animal room of the Laboratory Animal Research Institute of Sichuan Provincial Academy of Medical Sciences and Sichuan Provincial Citizens' Hospital, where the temperature was maintained at 23±2℃, the humidity at 55±5%, and the photoperiod at 16:8h (L:D). Before the experiment, the mice were adaptively reared for 2-3 days with free access to water and food. For 12 hours prior to the experiment, the mice were fasted but not deprived of water. Each group consisted of 10 test animals, and at least 6 usable data points were secured for each group. The animal experiments were conducted strictly in accordance with relevant regulations on laboratory animal management in China.
[0142] Test samples: The compounds obtained in the examples of the present invention (tested sample group) and breiaconitine A (positive control group) were each dissolved in 0.1 mol / L hydrochloric acid in a 1:1 molar ratio, and then diluted with physiological saline to the planned concentration for measurement. The blank control was physiological saline containing 0.1 mol / L hydrochloric acid. Except for changing the tested sample to physiological saline, the control group animals underwent the same treatment as the experimental group.
[0143] 2. Experimental Method (1) Measurement of analgesic activity (acetic acid rising method): Ten mice were randomly selected (half male and half female) and placed in separate mouse cages. The sample solution to be measured was injected subcutaneously into each mouse at a dose of 0.1 mL / 10 g body weight. After 15 minutes, a 0.7% acetic acid solution was injected intraperitoneally, and the mice were observed and the number of rising responses in each mouse within 15 minutes was recorded. The blank group was subcutaneously injected with physiological saline, the experimental group was injected with the sample to be measured, and the positive group was injected with breiaconitine A. Analgesic activity is expressed as the percentage reduction in the number of risings compared to the blank group (rising inhibition rate). The specific calculation formula is as follows. Rising suppression rate (pain relief rate) = (Average number of risings in the blank group - Average number of risings in the experimental group) / Average number of risings in the blank group × 100%
[0144] 50% effective dose (ED) 50 Measurement: The drug to be measured was dissolved in a 0.1 mol / L HCl solution in a 1:1 molar ratio, and then diluted geometrically with physiological saline to create at least five different dose-concentration groups. The rising inhibition rate for each dose group was measured using the above method, which measures analgesic activity by acetic acid rising. The obtained dose-inhibition rate data were entered into SPSS software (version 17.2), and the ED of the samples was determined by probit regression. 50 I calculated it.
[0145] (2) Acute toxicity and median lethal dose (LD50) 50 Measurement of LD50 (LD50) was performed by dissolving the drug in a 1:1 molar ratio in a 0.1 mol / L HCl solution, diluting it to the desired concentration with physiological saline, randomly selecting 10 mice from each group (half male and half female), placing them in separate cages, and subcutaneously injecting them with different sample solutions at a dose of 0.1 mL / 10 g body weight. In the acute toxicity preliminary experiment, the measurement concentration was set to 20 mg / kg, and then, based on the survival rate of the experimental animals obtained in the preliminary experiment, the drug was divided into at least 5 concentration / dose groups in a geometric progression. The survival rate of the mice within 24 hours was recorded by observation. The obtained dose-survival rate data was entered into SPSS software (version 17.2), and the LD50 of the drug was determined by probit regression. 50 I calculated it.
[0146] (3) Calculation of the Therapeutic Index (TI) value: The therapeutic index of the compound was calculated based on the 50% effective dose and the median lethal dose. The specific calculation formula is as follows. Therapeutic Index (TI) = Median Lethal Dose (LD50) / 50% Effective Dose (ED) 50 ).
[0147] (4) Measurement of anti-inflammatory activity: The effect of the compound at a concentration of 30 μM on the cellular activity of RAW264.7 cells was measured using the MTT method. The suppression of NO release in the LPS-induced inflammatory response of RAW264.7 cells by the compound at a concentration of 30 μM was measured using the Griess method. The specific methods are as follows.
[0148] MTT method: MTT was prepared in a 5 mg / ml solution using PBS buffer, filtered and sterilized using a 0.22 μm filter membrane, and then stored in a dark place under refrigeration. Each compound was accurately weighed, a 50 mmol / L mother liquor was prepared with DMSO, frozen and stored in a dark place, and then diluted to a 30 μmol / L solution with DMEM containing 10% FBS. RAW264.7 cells of three or more generations were added to the culture medium, and a cell suspension was prepared by gently pipetting until the cells detached. 10 μL was aspirated and placed on a glass slide, and after counting, 6 × 10⁶ 3 Cells were inoculated into a 96-well plate at 1 / well, with 100 μL of cell suspension in each well. After incubation at 37°C and 5% CO2 for 24 hours, the supernatant was aspirated. 100 μL of medium was added to each well of the zero group (CO group), and 100 μL of LDMSO (1 / 1000) was added to each well of the blank group (CK group). The sample to be measured (100 μL / well) was added to the experimental group. After 12 hours, the supernatant was aspirated, 5 μg / ml of MTT (120 μL / well) was added, and the cells were incubated at CO2 for 4 hours. After incubation, the supernatant was aspirated, DMSO (150 μL / well) was added, and the mixture was shaken for 10 minutes (50 r / min) in a shaker. The absorbance was measured at 492 nm. The relative cell activity (%) was calculated using the following formula. Cell-relative activity (%) = (OD 実験 -OD CO ) / (OD CK -OD CO) × 100%.
[0149] Griess method: Add RAW264.7 cells of 3 generations or more to the culture medium, gently pipette until the cells detach, prepare a cell suspension, aspirate 10 μL and place it on a glass slide, count the cells, and then measure 3 × 10 4 Cells were inoculated into 96-well plates, with 100 μL of cell suspension in each well. After incubation at 37°C and 5% CO2 for 24 hours, the supernatant was aspirated. 100 μL of DMSO (1 / 1000) was added to each well of the blank and LPS groups. The test sample (100 μL / well) was added to the experimental group. After 2 hours, 1 μg / ml of LPS (3 μL / well) was added to both the LPS and experimental groups. After 22 hours, 50 μL of supernatant was aspirated and placed in a new 96-well plate. Griess Reagent I (50 μL / well) from the NO kit was added, followed by Griess Reagent II (50 μL / well). Absorbance values were read at 562 nm and substituted into the standard curve to calculate the NO content. Calculation formula: NO inhibition rate (%) = (OD LPS -OD 実験 ) / (OD LPS -OD ブランク ).

Experimental Results Table 1: Analgesic activity and acute toxicity of each compound [Table 1] TIFF2026511621000118.tif254170TIFF2026511621000119.tif118170 a The mice showed clear signs of poisoning or death, and no analgesia rate was observed. In the blank group, physiological saline containing 0.1 mol / L HCl was used. b A 0% analgesic rate indicates that, under current experimental conditions, the inhibitory effect of this drug is below the detection limit or does not show a significant difference compared to other treatment groups. cIn acute toxicity experiments, mice were administered at a concentration of 20 mg / kg, and their deaths were observed within 24 hours. If death occurred, it was recorded as positive (+); if not, it was recorded as negative (-). *P<0.05; **P<0.01.
[0151] Table 2: ED of some compounds 50 LD 50 and treatment index [Table 2] a LD in the table 50 >X, when animals are treated with a drug concentration of X mg / kg under current experimental conditions, does not result in death or toxicity, and LD 50 This indicates that the concentration may be higher than this. 50 This needs to be confirmed through further experiments.
[0152] Table 3: Compound suppression rates of NO production in LPS-induced RAW264.7 cells [Table 3]
[0153] First, the effective dose of 50% of breiaconitine A as described in the literature (ED 50 The analgesic activity of the compounds was evaluated using an initial screening concentration of 0.05 mg / kg, and the acute toxicity of the compounds was evaluated by subcutaneous injection (initial concentration 20 mg / kg) (Table 1). As can be seen from the data in Table 1, all compounds obtained in the examples of the present invention, except for compounds 1 and 2, did not cause death in mice in the initial acute toxicity evaluation experiment, and their toxicity was far lower than that of breiaconitine A. Most of the compounds showed analgesic activity equivalent to breiaconitine A (based on an analgesic rate of 49% or higher). Therefore, compounds with an analgesic rate of 49% or higher were selected for 50% effective dose ED. 50The following was measured. Furthermore, since the compounds obtained in the examples of the present invention have low acute toxicity, the remaining compounds with relatively high analgesic activity (based on an analgesic rate of 40% or more in the initial screening activity) were selected and administered at 0.5 mg / kg (Table 1), and compounds with an analgesic rate of 60% or more at this concentration were selected for a 50% effective dose ED. 50 The median lethal dose (LD50) of the preferred compounds listed above was measured. 50 The following was measured. As can be seen from the data in Table 2, all of the preferred compounds listed above showed activity equivalent to that of breiaconitine A, but their toxicity was far lower than that of breiaconitine A, and their corresponding therapeutic indices were all higher than those of breiaconitine A.
[0154] Furthermore, the anti-inflammatory activity of the compounds was evaluated, and RAW cytotoxicity experiments were performed on compounds that had lower toxicity than breiaconitine A and good analgesic activity (based on an analgesic rate of 40% or more in initial screening activity) (Table 3). Subsequently, NO inhibition experiments were performed on compounds with a RAW cell viability of 85% or more to investigate their anti-inflammatory activity. As can be seen from the data in Table 3, some compounds have good anti-inflammatory activity (based on an NO inhibition rate of 40% or more) (Table 3).
[0155] As can be seen from the experimental results above, the compounds obtained in this invention have good analgesic and anti-inflammatory activity and low toxicity, and can be used in the preparation of effective and low-toxicity analgesics.
