Definitions

  • the present application relates to the technical field of medicines, in particular to a class of condensed ring compounds and their compositions as active ingredients, and the use of such compounds and their compositions for preparing analgesic drugs.
  • Pain is a self-protective reaction caused by tissue damage or potential tissue damage, accompanied by physiological conditions such as emotional anxiety and tension, and is a common symptom or accompanying symptom of many clinical diseases. Pain is divided into acute pain and chronic pain. Acute pain is mainly caused by surgery, severe physical trauma, etc. Chronic pain is usually caused by nociceptive pain, inflammation, neuropathic pain, migraine, etc.
  • Analgesics are a class of drugs that act on the central nervous system and can effectively relieve or eliminate pain without affecting other sensations. They are of great significance in first aid.
  • opioid alkaloids Opioids
  • NSAIDs nonsteroidal anti-inflammatory drugs
  • Opioid receptors include the classical mu, delta, kappa and nonclassical nociceptin (NOP) receptors.
  • ⁇ receptor agonists have the strongest analgesic effect, but usually increase addiction and even cause respiratory depression; ⁇ receptor agonists are less addictive, but the analgesic effect is far less than ⁇ receptor agonists; The analgesic effect of receptor agonists is between the two, but it is easy to cause side effects such as hallucinations, mydriasis, and irritability.
  • the current mainstream opioid receptor agonists mainly include morphine, oxycodone, fentanyl, sufentanil, remifentanil, and methadone. Worryingly, the current abuse of opioids has also led researchers to expand into new research directions, but most of them are in the early clinical stage.
  • Antipyretic and analgesic drugs are a class of drugs that can relieve fever and relieve local pain. They exert antipyretic and analgesic effects by inhibiting the synthesis and release of prostaglandins (PGs) in the hypothalamus, and usually have anti-inflammatory effects. These drugs are better for local pain, neuralgia, joint pain, menstrual pain and other dull pain, but less effective for other kinds of pain. At present, the commonly used ones are: aspirin, ibuprofen, voltaren, and chinoli, etc., but the use of such drugs needs to be considered in different situations.
  • PGs prostaglandins
  • Analgesics currently have relatively large side effects. Therefore, the development of high-quality analgesics is still imminent.

疼痛是一种因组织损伤或潜在的组织损伤产生的一种自我保护性反应，同时伴有情绪不安、紧张等生理情况，是临床多种疾病的常见症状或伴随症状。疼痛分为急性疼痛和慢性疼痛，急性疼痛主要是由手术、身体严重创伤等原因引起；慢性疼痛通常由伤害性疼痛、炎症、神经病理性疼痛偏头痛等原因引起。Pain is a self-protective reaction caused by tissue damage or potential tissue damage, accompanied by physiological conditions such as emotional anxiety and tension, and is a common symptom or accompanying symptom of many clinical diseases. Pain is divided into acute pain and chronic pain. Acute pain is mainly caused by surgery, severe physical trauma, etc. Chronic pain is usually caused by nociceptive pain, inflammation, neuropathic pain, migraine, etc.
镇痛药(Analgesics)是一类作用于中枢神经***，能有效缓解或消除痛觉又不影响其他感觉的药物，在急救中具有重要意义。目前申报上市的镇痛药物主要由阿片生物碱类(Opioids)、非甾体抗炎(Nonsteroidal Anti-inflammatory Drugs，NSAIDs)类等两大类，但阿片受体类药物仍占据主导地位。阿片受体包括经典受体μ、δ、κ和非经典痛敏肽(NOP)受体。μ受体激动剂的镇痛效果最强，但通常会增加瘾性，甚至引起呼吸抑制作用；δ受体激动剂的成瘾性较小，但镇痛效果远不及μ受体激动剂；κ受体激动剂的镇痛效果在两者之间，但容易引起幻觉、瞳孔散大、烦躁不安等副作用。目前主流的阿片受体激动剂主要有***、羟考酮、芬太尼、舒芬太尼、瑞芬太尼、***等。令人担忧的是，目前阿片类药物的滥用也使得研究人员扩展新的研究方向，但大多处于临床早期。解热镇痛药是一类能解热并减轻局部疼痛的药物，通过抑制下丘脑中的***素(PGs)的合成和释放，发挥解热和镇痛作用，通常兼有抗炎作用。 此类药物对局部疼痛、神经痛、关节痛、月经痛等钝痛效果较好，但对其他种类疼痛效果较差。目前临床常用的有：阿司匹林、布洛芬、扶他林和奇诺力等，但是此类药物的使用需分多种情况考虑。Analgesics are a class of drugs that act on the central nervous system and can effectively relieve or eliminate pain without affecting other sensations. They are of great significance in first aid. Currently, the analgesic drugs declared for marketing are mainly divided into two categories: opioid alkaloids (Opioids) and nonsteroidal anti-inflammatory drugs (NSAIDs), but opioid receptor drugs still occupy a dominant position. Opioid receptors include the classical mu, delta, kappa and nonclassical nociceptin (NOP) receptors. μ receptor agonists have the strongest analgesic effect, but usually increase addiction and even cause respiratory depression; δ receptor agonists are less addictive, but the analgesic effect is far less than μ receptor agonists; The analgesic effect of receptor agonists is between the two, but it is easy to cause side effects such as hallucinations, mydriasis, and irritability. The current mainstream opioid receptor agonists mainly include morphine, oxycodone, fentanyl, sufentanil, remifentanil, and methadone. Worryingly, the current abuse of opioids has also led researchers to expand into new research directions, but most of them are in the early clinical stage. Antipyretic and analgesic drugs are a class of drugs that can relieve fever and relieve local pain. They exert antipyretic and analgesic effects by inhibiting the synthesis and release of prostaglandins (PGs) in the hypothalamus, and usually have anti-inflammatory effects. These drugs are better for local pain, neuralgia, joint pain, menstrual pain and other dull pain, but less effective for other kinds of pain. At present, the commonly used ones are: aspirin, ibuprofen, voltaren, and chinoli, etc., but the use of such drugs needs to be considered in different situations.
镇痛药目前都有较大的副作用。因此，开发优质的镇痛药仍迫在眉睫。Analgesics currently have relatively large side effects. Therefore, the development of high-quality analgesics is still imminent.

实施例十五：β-淀粉样蛋白沉积抑制活性Example 15: β-amyloid deposition inhibitory activity
加速衰老的小鼠(SAMP8)63只，雄性(研究开始时为8个月大)，平均分成9组，每组7只。未干预组正常饮用自来水；实验组1-实验组8分别饮用用自来水溶解的含化合物(RE-01、RE-23、RE-31、RE-32、RE-33、RE-37、RE-45、RE-47)的溶液，给药剂量均为0.1mg/kg/日。给药八周后，取出鼠脑，用Methacarn(甲醇:氯仿:乙酸＝6:3:1)固定，并植入石蜡。然后，使用切片机制备8μm厚的切片。Accelerated aging mice (SAMP8), 63 males (8 months old at the start of the study), were divided into 9 groups with 7 mice in each group. The non-intervention group drank tap water normally; experimental group 1-experimental group 8 respectively drank tap water containing compounds (RE-01, RE-23, RE-31, RE-32, RE-33, RE-37, RE-45 , RE-47) solution, the dosage is 0.1mg/kg/day. Eight weeks after administration, the rat brain was taken out, fixed with Methacarn (methanol:chloroform:acetic acid=6:3:1), and embedded in paraffin. Then, 8 μm thick sections were prepared using a microtome.
使用VECTASTATIN ABC试剂盒对切片进行链霉抗生物素蛋白-生物素免疫染色。在10％的正常山羊血清中孵育一小时后，用PBS将抗β-淀粉样蛋白(Aβ)抗体稀释至10倍，并在4℃下孵育过夜。第二天，进行PBS清洗、用生物素化的抗兔二次抗体孵育1.5小时、PBS清洗，并用过氧化物酶标记的链霉抗生物素蛋白孵育1.5小时。用DAB使免疫反应可视化并制备样品。Sections were immunostained with streptavidin-biotin using the VECTASTATIN ABC kit. After incubation in 10% normal goat serum for one hour, the anti-β-amyloid (Aβ) antibody was diluted 10-fold with PBS and incubated overnight at 4°C. The next day, wash with PBS, incubate with biotinylated anti-rabbit secondary antibody for 1.5 hours, wash with PBS, and incubate with peroxidase-labeled streptavidin for 1.5 hours. Immunoreactions were visualized and samples prepared with DAB.
在显微镜下对海马体中的免疫反应性Aβ样颗粒进行计数。Aβ样免疫反 应性颗粒在海马体中作为棕色沉积物被观察到。每个个体用一切片进行计数。Immunoreactive Aβ-like granules in the hippocampus were counted under a microscope. Aβ-like immunoreactive granules were observed as brown deposits in the hippocampus. Each individual was counted using one slice.
如图2所示，在加速衰老小鼠(SAMP8)的未干预组中观察到了海马体中的β-淀粉样蛋白样免疫反应性。以0.1mg/kg/日的给药剂量情况下，在加速衰老的小鼠(SAM8)的实验组1-实验组8中，β-淀粉样蛋白样免疫反应性减小。这表明，由于本发明公开的化合物的干预，使β-淀粉样蛋白-免疫反应性颗粒的数量显著减少，所以，本发明公开的化合物能够抑制β-淀粉样蛋白沉积。As shown in Figure 2, β-amyloid-like immunoreactivity in the hippocampus was observed in the untreated group of accelerated aging mice (SAMP8). At a dose of 0.1 mg/kg/day, β-amyloid immunoreactivity was reduced in experimental groups 1 to 8 of accelerated aging mice (SAM8). This shows that the compounds disclosed in the present invention can inhibit the deposition of β-amyloid protein due to the significant reduction in the number of β-amyloid-immunoreactive granules due to the intervention of the compounds disclosed in the present invention.
