Abstract
Description
Technical Field
[0001] The present invention belongs to the field of pharmaceutical chemistry, and specifically relates to a class of dual degraders of estrogen and androgen receptors with high biological activity, a preparation method, a pharmaceutical composition and use thereof in medicine. Background Art
[0002] The incidence of breast cancer involves many factors, including lifestyle, social environment, mental health, and heredity or gene changes. In 2020, female breast cancer has surpassed lung cancer to become the most common cancer in the world, accounting for 11.7% of all cancers. In 2020, there were more than 2.26 million new cases of female breast cancer and about 685,000 deaths worldwide, accounting for 24.5% and 15.5% of the total number of new cancer cases and deaths in women, respectively.
[0003] Breast cancer is a systemic disease for which endocrine therapy is an important treatment. However, endocrine therapy resistance has become a difficult clinical problem. Studies have shown that women not only have estrogen and estrogen receptors (ER), but also widely express androgens and androgen receptors (AR). At the same time, AR is highly expressed in a considerable proportion of breast cancers and may play an important role in the occurrence and development of breast cancer: (1) ER α Positive breast cancer. Studies have shown that AR and ER α There is signal crosstalk in breast cancer, such as the N-terminus of AR can interact with ER α The ligand binding domain of AR binds to ER α There are common co-activator proteins; AR in ER α The expression of ER positive breast cancer is as high as 86.8%, and is significantly associated with tamoxifen treatment failure. α Potential targets for androgen receptor-positive breast cancer (Yang Man, Wei Wei, Research progress on androgen receptor in breast cancer treatment [J], Chinese Journal of Breast Disease (Electronic Edition), 2017, 11(05): 296-299). (2) Triple-negative breast cancer (TNBC), TNBC is a type of breast cancer that lacks ER α There is still a lack of effective clinical therapeutic targets for breast cancer subtypes that express AR. Studies have found that AR is also highly expressed in TNBC tissues, and as the only hormone receptor type, it accounts for 37%. AR is closely related to the prognosis of TNBC and can promote the growth and metastasis of TNBC cells. Currently, the clinical use of anti-androgen drugs alone to treat TNBC has shown a certain sensitivity, and AR inhibitors combined with other classic targeted therapeutic drugs have more potential value for the treatment of TNBC (Lu Yang, Wang Jinqiu, Guo Yu, Research progress on the role of androgen receptor in the treatment and prognosis of triple-negative breast cancer [J], Tumor, 2018, 38(12): 1155-1159+1164).
[0004] Currently, AR inhibitor drugs such as enzalutamide have entered clinical research for the treatment of breast cancer (Chen Junqing, Chen Zhanhong, Wang Xiaojia, Research progress of androgen receptor targeted therapy for triple-negative breast cancer [J], Journal of Oncology, 2018, 24(05): 499-503). In the Phase II clinical study (MDV3100-11) of the efficacy of enzalutamide in AR-positive advanced TNBC, 75 of the 118 patients enrolled were evaluable, with a 16-week clinical benefit rate of 35% (26 / 75) and a 24-week clinical benefit rate of 29% (22 / 75). The Phase IIB clinical study of enzalutamide combined with paclitaxel in the neoadjuvant treatment of triple-negative breast cancer (NCT02689427) will evaluate whether enzalutamide combined with weekly paclitaxel can further improve the pathological complete remission rate of AR-positive TNBC.
[0005] PROTAC (Proteolysis Targeting Chimeras) is a heterobifunctional molecule, one end of the molecule is connected to a ligand that binds to the target protein, and the other end is connected to a ligand of an E3 ligase, and the middle is connected by a suitable linker. PROTAC degrades the target protein through the ubiquitin proteasome system, directly mediating the degradation of the pathogenic target protein, which can overcome the drug resistance problem of traditional drugs. PROTAC mediates the formation of a ternary complex and labels the target protein with ubiquitination, which can be recycled in theory, so the amount of catalyst can play a role. Compared with traditional small molecule inhibitors, PROTAC can not only achieve selectivity that is difficult to achieve with traditional small molecules on certain targets, but also has significant advantages in improving activity. As a revolutionary technology, PROTAC has developed for 20 years, especially in the past 5 years. It has developed rapidly and has become a new direction for new drug research and development.
[0006] ARV-471 is a new anti-breast cancer drug developed by Arvinas, a leading company in the PROTAC field. It is currently in Phase II clinical trials abroad. In December 2021, Arvinas announced the safety and activity data of ARV-471 in patients with ER+ / HER2- locally advanced or metastatic breast cancer at the 44th San Antonio Breast Cancer Symposium (2021SABCS). The results showed good clinical benefits: Among 47 patients who were evaluable for clinical benefit (confirmed complete remission, partial remission, or stable disease ≥24 weeks), the clinical benefit rate of ARV-471 treatment was 40%, of which 3 cases achieved PR (another 1 case did not confirm PR), and the ORR was 7.89% (3 / 38). This result also shows that in order to achieve better clinical benefits, anti-breast cancer drugs based on ER degradation mechanisms need to be further studied.
[0007] In view of the clinical characteristics of breast cancer, in the in-depth development of anti-breast cancer drugs, ER / AR dual degraders are expected to become a novel and important technical path for anti-breast cancer drugs, but there is currently a lack of development or reports of such dual-mechanism drugs in the world.

[0080] Drug composition and dosage
[0081] The present invention also provides a pharmaceutical composition comprising a therapeutically effective amount of one or more compounds of formula (I) formulated with one or more pharmaceutical carriers (additives) and / or diluents, and optionally one or more of the above-mentioned other therapeutic agents. The compounds of the present invention can be administered in any suitable manner for any of the above-mentioned uses, for example, orally, such as tablets, capsules (each including sustained release or timed release preparations), pills, powders, granules, elixirs, tinctures, suspensions (including nanosuspensions, microsuspensions, spray-dried dispersions), syrups and emulsions; sublingually; buccally; parenterally, such as by subcutaneous, intravenous, intramuscular or intrasternal injection or infusion techniques (e.g., in the form of sterile injectable aqueous or non-aqueous solutions or suspensions); nasally, including administration to the nasal membrane, such as by inhalation spray; topically, such as in the form of creams or ointments; or rectally, such as in the form of suppositories. They can be administered alone, but are usually administered using a pharmaceutical carrier selected based on the selected route of administration and standard pharmaceutical practice.
[0082] Pharmaceutical carriers are formulated based on a number of factors that are within the purview of those skilled in the art. These factors include, but are not limited to: the type and nature of the active agent being formulated; the subject to whom the composition containing the active agent is to be administered; the intended route of administration of the composition; and the targeted therapeutic indication. Pharmaceutical carriers include aqueous and non-aqueous liquid media and various solid and semisolid dosage forms.
[0083] The carriers may include many different ingredients and additives in addition to the active agent, which are included in the formulation for various reasons known to those skilled in the art, such as stabilizing the active agent, binders, etc. Descriptions of suitable pharmaceutical carriers and factors involved in carrier selection can be found in a number of readily available sources, such as Allen, LV Jr. et.al. Remington: The Science and Practice of Pharmacy (2 Volumes), 22nd Edition (2012), Pharmaceutical Press.
[0084] Of course, the dosage regimen of the compounds of the invention varies depending on known factors, such as the pharmacodynamic properties of the specific agent and its mode and route of administration; the species, age, sex, health condition, medical condition and weight of the recipient; the nature and extent of symptoms; the type of concurrent treatment; the frequency of treatment; the route of administration, the patient's renal and liver function and the desired effect. According to general guidance, when used for a specified effect, the daily oral dosage of each active ingredient should be about 0.001 mg / day to about 10-5000 mg / day, preferably about 0.01 mg / day to about 1000 mg / day, and most preferably about 0.1 mg / day to about 600 mg / day. During a constant rate infusion, the most preferred intravenous dosage should be about 0.01 mg / kg / minute to about 10 mg / kg / minute. The compounds of the invention can be administered in a single daily dose, or the total daily dose can be administered in divided doses twice, three times or four times a day.
[0085] The compound can usually be administered in a mixture with suitable pharmaceutical diluents, excipients or carriers (collectively referred to as pharmaceutical carriers in the present invention) appropriately selected according to the intended administration form (eg, oral tablets, capsules, elixirs and syrups) and in accordance with conventional pharmaceutical practice.
[0086] Dosage forms (pharmaceutical compositions) suitable for administration may contain from about 0.1 mg to about 2000 mg of active ingredient per dosage unit. In these pharmaceutical compositions, the active ingredient will generally be present in an amount of about 0.1-95% by weight based on the total weight of the composition.
[0087] A typical injectable preparation can be prepared as follows: at least one compound of the present invention (250 mg) is aseptically placed in a vial, lyophilized in an aseptic manner and sealed. For use, the vial contents are mixed with 2 mL of physiological saline to produce an injectable preparation.
[0088] The scope of the present invention includes (alone or in combination with a pharmaceutical carrier) a pharmaceutical composition comprising a therapeutically effective amount of at least one compound of the present invention as an active ingredient. Optionally, the compound of the present invention can be used alone, in combination with other compounds of the present invention, or in combination with one or more other therapeutic agents (e.g., anticancer agents or other pharmaceutically active substances).
[0089] Regardless of the selected administration route, the compound of the present invention (which may be used in a suitable hydrated form) and / or the pharmaceutical composition of the present invention are formulated into a pharmaceutical dosage form by conventional methods known to those skilled in the art.
[0090] Actual dosage levels of the active ingredients in the pharmaceutical compositions of the present invention may be varied so as to obtain an amount of the active ingredient that is effective to achieve the desired therapeutic response for a particular patient, composition, and mode of administration, without being toxic to the patient.
[0091] The selected dosage level will depend upon a variety of factors, including the activity of the specific compound of the present invention being employed, or its ester, salt or amide; the route of administration; the time of administration; the rate of excretion of the specific compound being employed; the rate and extent of absorption; the duration of the treatment; other drugs, compounds and / or substances used in combination with the specific compound being employed; and the age, sex, weight, condition, general health and prior medical history of the patient being treated and other factors well known in the medical art.
[0092] A doctor or veterinarian with ordinary skills in the art can easily determine and prescribe the desired pharmaceutical composition of an effective amount. For example, in order to achieve the desired therapeutic effect, a physician or veterinarian can start the dosage of the compound of the present invention used in the pharmaceutical composition at a level lower than the desired level, and gradually increase the dosage until the desired effect is achieved. Generally, the compound of the present invention of a suitable daily dose will be the amount of the compound of the lowest dose that effectively produces a therapeutic effect. Such an effective dose generally depends on the above factors. Generally, the range of the compound of the present invention for oral, intravenous, intraventricular and subcutaneous doses for patients is about 0.01 to about 1000 mg / kg body weight / day. If necessary, the active compound of the effective daily dose can be administered separately at appropriate intervals in two, three, four, five, six or more subdoses in a day, optionally in a unit dosage form. In certain aspects of the present invention, medication is administered once a day.
[0093] While it is possible for a compound of the present invention to be administered alone, it is preferable to administer the compound as a pharmaceutical formulation (composition).
[0094] The above features mentioned in the present invention or the features mentioned in the embodiments can be combined in any way.
