  The present invention pertains generally to the field of therapeutic compounds. More specifically the present invention pertains to certain substituted pyrazolo[1,5-a]pyrimidine-7-amine compounds PPA that, inter alia, inhibit cyclin-dependent protein kinases (CDKs), especially CDK12 and/or CDK13, and are selective, for example, for CDK12 and/or CDK13 as compared to CDK7. In addition to selectively inhibiting CDK12 and/or CDK13, the compounds also act as selective Cyclin K degraders thereby removing the key cofactor required for CDK12 and/or CDK13 activation; this confers additional cellular potency and selectivity. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit CDK, especially CDK12 and/or CDK13; and to treat disorders including: disorders that are associated with CDK, especially CDK12 and/or CDK13; disorders that result from an inappropriate activity of a CDK, especially CDK12 and/or CDK13; disorders that are associated with CDK mutation, especially CDK12 and/or CDK13mutation; disorders that are associated with CDK overexpression, especially CDK12 and/or CDK13 overexpression; disorders that are associated with upstream pathway activation of CDK, especially CDK12 and/or CDK13; disorders that are ameliorated by the inhibition of CDK, especially CDK12 and/or CDK13; proliferative disorders; cancer; viral infections (including HIV); neurodegenerative disorders (including Alzheimer's disease and Parkinson's disease); ischaemia; renal diseases; cardiovascular disorders (including atherosclerosis); autoimmune disorders (including rheumatoid arthritis); and disorders caused by dysfunction of translation in cells (including muscular dystrophy). Optionally, the treatment further comprises treatment (e.g., simultaneous or sequential treatment) with a further active agent which is, e.g., a DNA repair inhibitor, an immune checkpoint inhibitor, an agent stimulating the immune system, a cell cycle checkpoint inhibitor, a Her2 blocker, a transcriptional inhibitor, a cytotoxic chemotherapeutic agent, etc.

  本发明涉及治疗化合物领域。更具体地说，本发明涉及某些取代的吡唑并[1,5-a]嘧啶-7-胺化合物PPA，这些化合物在抑制细胞周期依赖蛋白激酶（CDKs）方面具有选择性，特别是CDK12和/或CDK13，并且相对于CDK7具有选择性。除了选择性地抑制CDK12和/或CDK13外，这些化合物还作为选择性的Cyclin K降解剂，从而去除了CDK12和/或CDK13激活所需的关键辅因子；这赋予了额外的细胞效力和选择性。本发明还涉及包含这些化合物的制药组合物以及在体内外使用这些化合物和组合物来抑制CDK，特别是CDK12和/或CDK13，并治疗与CDK，特别是CDK12和/或CDK13相关的疾病，包括：由CDK，特别是CDK12和/或CDK13引起的疾病；由CDK突变，特别是CDK12和/或CDK13突变引起的疾病；由CDK过表达，特别是CDK12和/或CDK13过表达引起的疾病；由CDK上游通路激活，特别是CDK12和/或CDK13激活引起的疾病；由抑制CDK，特别是CDK12和/或CDK13抑制改善的增殖性疾病；癌症；病毒感染（包括艾滋病毒）；神经退行性疾病（包括阿尔茨海默病和帕金森病）；缺血；肾脏疾病；心血管疾病（包括动脉粥样硬化）；自身免疫性疾病（包括类风湿性关节炎）；以及由细胞翻译功能障碍引起的疾病（包括肌萎缩性侧索硬化症）。可选地，治疗还进一步包括与另一种活性剂的治疗（例如，同时或顺序治疗），该活性剂可以是DNA修复抑制剂、免疫检查点抑制剂、刺激免疫系统的剂、细胞周期检查点抑制剂、Her2阻断剂、转录抑制剂、细胞毒化学治疗剂等。

  HER2-positive (HER2+) breast cancer is defined by HER2 oncogene amplification on chromosome 17q12 and accounts for 15–20% population of breast-cancer patients. Therapeutic anti-HER2 antibody such as trastuzumab is used as the first-line therapy for HER2-positive breast cancers. However, more than 50% of the patients respond poorly to trastuzumab, illustrating that novel therapy is warranted to overcome the resistance. We previously reported that in the majority of HER2+ breast-cancer patients, CDK12 is co-amplified on 17q12 and involved in developing tumors and trastuzumab resistance, proposing CDK12 as a potential drug target for HER2+ breast cancers. Here, we designed and synthesized novel 2,6,9-trisubstituted purines as potent CDK12 inhibitors showing strong, equipotent antiproliferative activity against trastuzumab-sensitive HER2+ SK-Br3 cells and trastuzumab-resistant HER2+ HCC1954 cells (GI50 values < 50 nM) both of which express a high level of CDK12. Two potent analogue 30d and 30e at 40, 200 nM greatly downregulated the levels of cyclinK and Pol II p-CTD (Ser2), as well as the expression of CDK12 downstream genes (IRS1 and WNT1) in a dose-dependent manner. We also observed structure-property relationship for a subset of potent analogues, and found that 30e is highly stable in liver microsomes with lack of CYP inhibition. In addition, 30d exhibited a synergy with trastuzumab in the both cells, suggesting that our inhibitors could be applied to alleviate trastuzumab-resistance of HER2+ breast cancers and escalate the efficacy of trastuzumab as well. Our study may provide insight into developing a novel therapy for HER2+ breast cancers.

  HER2阳性（HER2+）乳腺癌是由17q12染色体上HER2癌基因扩增定义的，占乳腺癌患者人群的15-20％。治疗HER2阳性乳腺癌的一线疗法是使用抗HER2抗体如曲妥珠单抗。然而，超过50％的患者对曲妥珠单抗反应不佳，说明需要新的治疗方法来克服耐药性。我们先前报道，在大多数HER2+乳腺癌患者中，CDK12在17q12上共扩增，并参与肿瘤和曲妥珠单抗耐药性的发展，因此建议CDK12作为HER2+乳腺癌的潜在药物靶点。在这里，我们设计和合成了新型2,6,9-三取代嘌呤作为强效CDK12抑制剂，对曲妥珠单抗敏感的HER2+ SK-Br3细胞和曲妥珠单抗耐药的HER2+ HCC1954细胞（GI50值<50 nM），都表现出强大、等效的抗增殖活性，这两种细胞都表达高水平的CDK12。两种强效类似物30d和30e在40、200 nM时，明显降低了cyclinK和Pol II p-CTD（Ser2）的水平，以及CDK12下游基因（IRS1和WNT1）的表达，呈剂量依赖性。我们还观察到一些强效类似物的结构-性质关系，并发现30e在肝微粒体中非常稳定，没有CYP抑制作用。此外，30d在两种细胞中与曲妥珠单抗表现出协同作用，表明我们的抑制剂可用于减轻HER2+乳腺癌对曲妥珠单抗的耐药性，并提高曲妥珠单抗的疗效。我们的研究可能为HER2+乳腺癌的新型治疗提供洞见。
