Abstract
Description
A tetrahydroquinoline ntd inhibitor and application thereof TECHNICAL FIELD
[0001] The present application belongs to the technical field of biological medicine, and particularly relates to a tetrahydroquinoline NTD inhibitor and application thereof. BACKGROUND
[0002] Prostate cancer is a very important tumor of the male reproductive system, ranking second in the world's common male malignancies and the fifth largest cause of cancer death (Bay F, Ferlay J, Soerjomatamam I, et al. Global cancer statistics 2018: globocan estimates of incidence and mortality worldwide for 36 cancers in 185 countries[J]. CA Cancer J Clin. 2018, 68:394-424.). Prostate cancer is histologically manifested as adenocarcinoma, mainly of the luminal phenotype, accompanied by basal cell loss (Zhang DX, Tang D. "Splice" a way toward neuroendocrine prostate cancer[J]. EBioMedicine, 2018, 35:12-13.). The incidence of prostate cancer is increasing year by year, and the latest US cancer statistics show that the incidence of prostate cancer in American men is 20%, which has surpassed lung cancer and ranked first; the mortality rate of prostate cancer is 10%, second only to lung cancer, ranking second (Siegel RL, Giaquinto AN, Jemal A. Cancer statistics, 2024[J]. CA Cancer J Clin, 2024, 74(1):12-49.). Prostate cancer is characterized by a long natural history of the disease, during which different treatments are needed according to tumor stage and invasiveness. The treatment of early prostate cancer includes surgical resection, chemotherapy and castration therapy, while for patients with advanced metastatic prostate cancer, there is currently no radical treatment, and only conservative treatment can be taken (Achan V, Putora PM, Omlin A, et al. Metastatic prostate cancer: treatment options[J]. Oncotarget, 2022, 100):48-59.). Even though most prostate cancers are discovered at an early stage, a portion of patients are diagnosed with locally advanced or even distant metastasis. The common methods for treating non-metastatic prostate cancer are radical prostatectomy and androgen deprivation therapy (ADT), and radical prostatectomy is only suitable for prostate cancer patients who are younger and can tolerate surgery.But after ADT treatment with a median time of 18-24 months, almost all patients inevitably develop castration-resistant prostate cancer (CRPC), and more than 80% of CRPC eventually turn into metastatic castration-resistant prostate cancer (mCRPC) (Oudard S, Progress in emerging therapies for advanced prostate cancer [J]. Cancer Treat Rev, 2013, 39(3): 275-289; Labriola Mk, Atig S, Hirshman N, et al. Management of men with metastatie casration-resistant prastate cancer following potent androgen receptor inhibition: a review of novel investigation-al therapies [J]. Prstate Cancer Prastatie Dis, 2021. 24(2); 301-309.) with a median survival of less than 3 years. In addition, endocrine therapy is also the first-line treatment for these patients. Although the treatment regimen dominated by endocrine therapy has achieved good results in clinical practice, after 2 years of treatment, prostate cancer cells will develop resistance to androgen deprivation, leading to disease progression to castration-resistant prostate cancer (CRPC) (Leiblich A, Hellberg I E E U, Sekar A, er al. Mating induces switch from horone-dependent to hormone-independent steroid receptor-mediated growth in Drosophila secondary cells [J]. PLoS Biol, 2019, 17(10): e3000145.). So far, little is known about the potential mechanisms of the development and maintenance of castration-resistant prostate cancer, leading to a lack of new therapeutic drugs for such a deadly disease. Therefore, finding new therapeutic targets is crucial to improve the prognosis of prostate cancer patients.
[0003] Androgen Receptor (AR) is an important target for prostate cancer drugs, and its structure plays an important guiding role in drug development. Androgen receptor is composed of four domains, including N-terminal binding domain (NTD), DNA binding domain (DBD), hinge region (HR), and C-terminal binding domain (LBD). NTD is the transcription activation region, which is the most non-conserved sequence region, encoded by exon 1, and contains two independent transcription activation function regions AF1 and AF5. AF1 region also contains two transcription units Tau-1 and Tau-5 (Duan M, Liu N, Zhou w, er al. Structural diversity of ligang-binging androgen recertors revealed by microsecond long molecular dynamics simulations and enhanced sampling[J]. J Chem Theony Compu, 2016, 12(9): 4611-4619; Helsen C, Claessens F. Looking at nuclear receptors from a new angle[J]. Mol Cell Endocrinol, 2014, 382(1): 97-106.). In recent years, small molecule androgen receptor inhibitors targeting NTD domain have emerged. The NTD domain of androgen receptor is essential for androgen receptor activity and exists in all forms of androgen receptor. Targeting this key region is expected to inhibit the activity of resistance-related androgen receptor splice variants and overcome the shortcomings of current drug therapy. EPI-001 is a new type of small molecule isolated from marine sponge extract, which can bind to AR NTD and prevent the interaction between protein and ligand. Although EPI-001 does not reduce the level of AR in serum, it can directly inhibit the activity of AR splice mutant and prevent its interaction with full-length AR (Sadar, M. D. Small molecule inhibitors targeting the "achilles' heel" of androgen receptor activity[J]. Cancer Res, (2011), 71(4): 1208-1213.). EPI-002 has entered the phase II clinical study stage (NCT02606123).Myung et al. found that EPI analogs covalently bind to the NTD to block the transcriptional activity of the androgen receptor and its splice variants and reduce the growth of CRPC xenografts (Myung IK, Banuelos CA, Fernandez JG eral. An androgen receptor N-terminal domain antagonist for treating prostate cancer [J]. J Clin invest, 2013, 123(7): 2948-2960). In addition, Banuelos et al. found that the binding site of EPI-001 is Tau-5 in AF1 (Banuelos C A, Tavakoli l, Tien A H, er al. Sintokamide A is novel antagonist of androgen receptor that uniquely binds activation function-1 in its amino-terminal domain [J]. J Biol Chem, 2016, 291(42): 22231-22243.).
[0004] The main drugs for treating prostate cancer in clinical practice are androgen receptor inhibitors, which can be divided into two categories: steroidal inhibitors and non-steroidal inhibitors. Steroidal inhibitors include cyproterone acetate. Steroidal inhibitors can bind to the receptor due to their structural similarity to androgens, and were initially used in clinical practice to treat prostate cancer. However, they were found to have adverse reactions such as liver toxicity and loss of sexual desire, which limited their clinical application (Sakkiah S, Ng H W, Tong W, et al. Structures of androgen receptor bound with ligands: advancing understanding of biological functions and drug discovery [J]. Expert Opin Ther Pat, 2016, 20(10): 1267-1282.). The first generation of non-steroidal inhibitors includes flutamide, nilutamide, and bicalutamide. They initially showed anti-androgen activity without agonistic effects, and were therefore used in clinical practice to treat prostate cancer. However, their use eventually led to an increase in serum testosterone levels, similar to steroidal inhibitors (Denmeade S R, Isaacs JT. A history of prostate cancer treatment [J]. Nat Rev Cancer, 2002, 2(5): 389-396.). The second generation of non-steroidal inhibitors includes enzalutamide, ARN-509, and ODM-201, all of which have been marketed. Non-steroidal inhibitors are more widely used in clinical practice due to their high selectivity and good tolerance, and the absence of side effects associated with steroidal drugs (Wirth M P, Hakenberg O W, Froehner M. Antiandrogens in the treatment of prostate cancer [J]. Eur Urol, 2007, 51(2): 306-313.). Therefore, non-steroidal inhibitors are the main direction of research in recent years. The non-steroidal androgen receptor inhibitors currently used in clinical practice all act on the LBD binding domain, which is a single target, making it difficult to treat prostate cancer patients. With the extension of the medication time, patients will inevitably develop drug resistance, and will eventually face the situation of having no available drugs. Through the understanding of the structure of the androgen receptor, the NTD binding domain and the DBD binding domain in the androgen receptor can also be used as targets for anti-prostate cancer drugs, making the selection of drugs for treating prostate cancer more diverse. In clinical practice, a multi-target combination drug strategy can be used to increase the efficacy and improve the quality of life of prostate cancer patients. SUMMARY
