• the use of receptor-mediated or dependent diseases or conditions, the diseases are particularly preferably breast cancer.
• Estrogen is a steroid hormone secreted by the endocrine system and plays an important role in the reproductive system, bone tissue, cardiovascular, immune system and central nervous system.
• the estrogen signaling system plays an important role in regulating cell growth, differentiation and apoptosis.
• the occurrence and development of estrogen-dependent tumors such as breast cancer, ovarian cancer, and endometrial cancer are closely related to estrogen.
• the main chemotherapy for breast cancer is to use anti-estrogens such as tamoxifen, but tamoxifen exhibits the properties of an estrogen agonist in the uterus and has a stimulating effect on cancer cells in the uterus. Because of these serious side effects, it is imperative to seek new safe and effective treatments.
• ER estrogen receptor
• ER is a steroid hormone receptor, a ligand-activated transcription factor that belongs to the nuclear receptor superfamily. It contains two subtypes: each is composed of different genes. Encoded ER ⁇ (discovered in 1950) and ER ⁇ (discovered in 1996). ER ⁇ and ER ⁇ show a high degree of similarity at the amino acid level. The similarity in the DNA binding domain is as high as 97%, and the similarity in the ligand binding domain is as high as 56%. However, there is only 24% low homology at the N-terminus. Source. The ER contains 6 structural domains (AF), which constitute 4 main functional areas.
• AF structural domains
• the functional area of the N-terminal A/B domain has a ligand-independent transcriptional activation functional area AF-1, which has constitutive activation activity. By interacting with basic transcription factors, resurrection factors and other transcription factors, the transcription of target genes is activated. There are multiple phosphorylation sites in this region. It is reported that the role of AF-1 depends on the phosphorylation of proteins.
• the DNA binding domain (DBD) composed of the C domain is highly conserved and contains two zinc finger domains, which can specifically bind to the target DNA. At the same time, this domain plays an important role in the dimerization of the receptor. . Domain D is the hinge region, linking DBD and ligand domain (LBD), with low conservation (the homology of the two subtypes is only 30%).
• the C-terminal E domain constitutes the ligand binding domain (LBD), which determines the relationship between ER and estrogen, SERM (selective estrogen receptor modulator), SERD (selective estrogen receptor downregulator) and other ligands Specific binding.
• LBD has a ligand-dependent transcriptional activation functional area AF-2, which cooperates with AF-1 to play the function of ER receptor activating target gene transcription.
• AF-2 ligand-dependent transcriptional activation functional area
• LBD has a strong dimerization interface and can still play a role in the absence of ligands. Therefore, LBD is a key part of receptor dimerization.
• ER ⁇ is mainly distributed in the uterus, ovaries, testes, pituitary, kidney, epididymis and adrenal glands, while ER ⁇ is mainly distributed in the prostate, ovaries, lungs, bladder, brain and blood vessels. Since full agonists or full antagonists have serious side effects, SERM research came into being. Its "selectivity" means that SERM behaves as an agonist in certain tissues such as bone, liver, and the ER ⁇ concentration area of the cardiovascular system, while it behaves as an antagonist in other tissues such as the breast. It can be an agonist or an antagonist in the uterus (the more prominent area of ERa).
• SERMs currently on the market include Tamoxifen, Raloxifene, Bazedoxifene and Toremifene, etc.
• studies have found that the SERMs currently on the market are still serious
• long-term use of tamoxifen and toremifene can cause endometrial hyperplasia, polyps and endometrial cancer.
• the common side effects of raloxifene include hot flashes, leg pain, breast swelling and pain and veins. Embolism and so on. Therefore, the research and development of new compounds is still a problem to be solved.
• Tamoxifen which belongs to a class of compounds called selective estrogen receptor modulators (SERMs), has the effect of stabilizing ER ⁇ and slightly upregulating ER ⁇ receptor levels; in contrast, fulvestrant (fulvestrant) causess the rapid degradation of ER ⁇ and exacerbates the blockade of the ER receptor signaling pathway.
• SERMs selective estrogen receptor modulators
• fulvestrant fulvestrant
• SEDs selective estrogen receptor downregulators
• SERDs such as Fulvestrant can effectively treat some ER ⁇ -positive breast cancers that are resistant to tamoxifen. Therefore, compounds that cause ER ⁇ degradation can be used to prolong the duration of the efficacy of anti-estrogen therapy (possibly using different SERMs, aromatase inhibitors and SERDs in sequence) for successful treatment of breast cancer patients.
