Definitions

  • the present invention belongs to the field of medicine, and specifically relates to a new class of compounds and their use for degrading androgen receptor (AR). These compounds can degrade AR and can be used as AR inhibitors or degradants for the treatment of diseases such as prostate cancer.
  • AR degrading androgen receptor
  • Prostate cancer has become an important disease threatening men's health.
  • prostate cancer is the highest incidence of male tumors, and the mortality rate is second only to lung cancer.
  • the annual incidence of prostate cancer is also increasing at a rate of about 10%.
  • the growth of prostate cancer is almost entirely dependent on the androgen receptor (AR) pathway.
  • AR has become a research hotspot in the field of biomedicine.
  • prostate cancer patients can be cured by surgery. However, about 30% of prostate cancer patients will relapse due to distant metastasis of cancer cells, forming advanced disease.
  • androgen therapy can be used, that is, castration combined with antiandrogen therapy. Castration reduces the circulating levels of androgens and the activity of androgen receptor (AR).
  • Antiandrogen therapy can competitively bind to androgens and block the function of androgen receptor (AR). Although this therapy is effective at first, it will quickly fail and turn into hormone-refractory prostate cancer.
  • AR has been confirmed as the cause of hormone-refractory prostate cancer.
  • Overexpression of AR can cause hormone-sensitive prostate cancer to develop into hormone-refractory prostate cancer, so AR is a therapeutic target for hormone-refractory prostate cancer.
  • the overexpression of AR in hormone-refractory prostate cancer can convert anti-androgen antagonists into agonists, which is an important reason why androgen therapy cannot prevent the development of prostate cancer in the later stage of treatment.
  • Seeking drugs with stronger AR antagonism and smaller AR agonistic activity is an important direction for the development of treatment of hormone-refractory prostate cancer.
  • enzalutamide which was approved for marketing in 2012, is used for prostate cancer and metastatic castration. Treatment of resistant prostate cancer. However, about 20%-40% of prostate cancer patients are innately resistant to enzalutamide. Those prostate cancer patients who are initially sensitive to enzalutamide will eventually develop resistance after long-term treatment.
  • AR has also become a new target for the treatment of breast cancer, and the clinical trial of enzalutamide for the treatment of breast cancer has entered the phase II clinical study.
  • AR also plays an important role in hormone-related diseases such as acne, hair loss, and benign prostate enlargement.
  • the purpose of the present invention is to provide a class of compounds which can degrade AR and can be used as AR inhibitors or degradants for the treatment of diseases such as prostate cancer.

Abstract

本发明提供了一类具有降解雄激素受体(AR)活性的化合物,具体地,本发明提供了一种如下式(I)所示的化合物;其中,各基团的定义如说明书中所述。本发明的化合物具有很好的雄激素受体(AR)降解活性,可以用于制备治疗AR表达相关疾病的药物。

Description

具有降解雄激素受体活性的化合物 技术领域
本发明属于医药领域,具体地涉及一类新化合物及其能降解雄激素受体(AR)的用途。这些化合物能降解AR,并且可用作AR抑制剂或降解剂用于治疗前列腺癌等疾病。
背景技术
前列腺癌已成为威胁男性健康的重要疾病。在北美和欧洲,前列腺癌是发病率最高的男性肿瘤,死亡率仅次于肺癌。在中国,前列腺癌每年的发病率也以10%左右的速度增长。前列腺癌的生长几乎完全依赖雄激素受体(AR)途径,AR作为雄激素发挥生物学效应的靶点,已成为生物医学领域研究的热点。
部分前列腺癌患者可通过手术治愈。但约有30%的前列腺癌患者会因为癌细胞远处转移而复发,形成晚期疾病。对于这类晚期疾病患者可采用去雄激素疗法治疗,即:去势结合抗雄激素药物治疗。去势能降低雄激素的循环水平和雄激素受体(AR)的活性。抗雄激素药物治疗能竞争性的与雄激素结合而阻断雄激素受体(AR)的功能。这一疗法虽然一开始有效,但会迅速失效而转变为激素难治性前列腺癌。
近年来,AR的过度表达已经被确证是导致激素难治性前列腺癌形成的原因。AR的过表达会导致激素敏感性前列腺癌发展为激素难治性前列腺癌,因而AR是激素难治性前列腺癌的治疗靶点。并且在激素难治性前列腺癌中AR的过表达可将抗雄激素的拮抗剂转化成激动剂,这是去雄激素疗法治疗后期不能防止前列腺癌发展的重要原因。
寻求具有更强的AR拮抗和更小AR激动活性的药物是开发治疗激素难治性前列腺癌的重要方向,例如:2012年获批上市的恩杂鲁胺,用于前列腺癌,转移性去势抵抗性前列腺癌的治疗。然而约20%~40%的前列腺癌患者对恩杂鲁胺先天性耐药,那些一开始对恩杂鲁胺敏感的前列腺癌患者,在长期治疗之后最终还是会出现耐药。
近年来,AR也成为治疗乳腺癌的新靶点,恩杂鲁胺治疗乳腺癌的临床试验已进入二期临床研究。此外,越来越多的研究表明AR在青春痘、脱发、良性前列腺肿大等荷尔蒙相关的疾病中也发挥重要作用。
发明内容
本发明的目的就是提供一类化合物,其能将AR降解,并且可用作AR抑制剂或降解剂用于治疗前列腺癌等疾病。
在本发明的第一方面,提供了一种如下式I所示的化合物,其异构体、前药、或其药学上可接受的盐:
