Description
Technical Field
The invention belongs to the field of opioid receptor antagonists, and relates to the discovery of an action target point of an alkaloid compound in safflower seeds, in particular to the discovery of action target points of kct11, kct12, kct17 and kct33 in the alkaloid compound. The alkaloid compounds are kct11, kct12, kct17, kct, derivatives and corresponding pharmaceutically acceptable salt-forming compounds; the target is Mu opioid receptor; the application is the prevention and treatment of diseases such as opioid addiction, tolerance, respiratory depression, constipation, cancer and the like.
Background
Safflower seed is the seed of the asteraceae plant safflower (Carthamus tinctorius l.), known as "western Ping Zi". The safflower seed oil has the effects of dredging channels and relieving pain, and activating blood and dissolving stasis, and is mainly used for treating amenorrhea due to blood stagnation, dysmenorrhea, arthralgia, traumatic blood stasis and swelling, macula and the like. Clinical and pharmacological studies show that safflower is beneficial to nervous system, cardiovascular and cerebrovascular and immune system, and has pharmacological activities of analgesia, anti-inflammatory, antibacterial, anti-tumor and anti-fatigue. However, most of the current research is focused on the cellular level, and little research is done on the target site of action of pure compounds (Yuan Qinqin, liu Wenying. Research on bioactive components and functional properties of safflower has progressed. Food industry science 2020,41 (03): 432-344;Sun LP,Shi FF,Wang K,et al.Antioxidant and Anti-Inflammatory Activities of Safflower (Carthamus tinctorius L.) Honey extract. FOODS.2020,9 (8): 1039-1054).
Opioid receptors are a member of the superfamily of G protein-coupled receptors, mainly in central and peripheral neurons, and neuroendocrine (pituitary, adrenal), immune and ectodermal cells, expressed in mainly 4 subtypes: mu, kappa, delta and NOP. Research has shown that opioid receptors are associated with diseases such as pain, nervous system, respiratory system, gastrointestinal system, cancer, etc. At present, a great number of opioid analgesics have remarkable side effects, such as drug addiction, drug tolerance, respiratory depression, constipation and the like. And researches show that the opioid receptor antagonist has the efficacy of preventing and treating side effects of opioid analgesic drugs. There are studies reporting that the development of cancer at opioid receptors is closely related. Thus, new Opioid Receptor antagonists have been discovered to provide targeted therapies for Opioid-induced diseases, as well as cancer (Xiaolin, z., zheng, y., and Ruibin, s.research progress in drugs based on Opioid Receptor subtypes.chinese Journal of Pharmacology and toxicology.2017,31 (4): 346-351; yang Huan, bao Jingying, jiang Miaomiao, etc. analgesic effects of Opioid agonists and target pathway research developments therefor Anhui medicine 2017,21 (02): 211-215; pan Chenling, meng Hao, wang Liangliang, et al, recent hot spot in Opioid Drug development, organic chemistry, 2018,38 (10): 2625-2632, zhu Lianghan, cui Zhiying, zhu Qihua, et al, opioid Receptor agonist research evolution, pharmaceutical evolution, 2018,42 (07): 537-543, trescot, a.m., datta, s., lee, m., et al, operational pharmaceutical, pain, 2008,11 (2): S133-S153, fe, y., he, x.z., yang, y.l., et al, current Research on Opioid Receptor function, current targets, 2012,13 (2): 230-246, singleton, p.a., movement, j., karp.d., et al, temperature operation receiver: A New Target for Cancer Therapy.

Compounds kct (N-P-Coumaroyl Serotonin/N-P-coumaroyl serotonin), kct, kct17 and kct (N-Cinnamoyl Serotonin/cinnamoyl serotonin) were derived from Kunming plant institute, national academy of sciences. The stably transformed cell line (HEK 293T-Mu) highly expressing the humanized Mu opioid receptor is derived from university of California Europe division in the United states; loperamide (cat# 0840) was purchased from Tocres. Dimethyl sulfoxide (DMSO, cat# A503039-0250). HBSS buffer (Gibco, 14065056). The detection platform is Kang Ningdi third generationThe signal detected by the imager is the wavelength shift caused by the Dynamic Mass Reset (DMR) of the cell.
