Definitions

  • the invention belongs to the technical field of medicine, and particularly relates to a heterocyclic substituted pyrimidine compound, a pharmaceutically acceptable salt thereof or a stereoisomer thereof, a preparation method of these compounds, and a preparation of the compound for enhancing cGMP signaling function.
  • cGMP guanosine-3', 5'-cyclic phosphate, cyclic guanosine monophosphate
  • PDE-5 phosphodiesterase-5
  • PDE-5 inhibitors can be used for diseases caused by cGMP signaling dysfunction, including hypertension, heart failure, pulmonary hypertension, erectile dysfunction, benign prostatic hyperplasia, and female sexual dysfunction.
  • Erectile dysfunction is the most common sexual dysfunction in adult men. It refers to a disease in which the penis continues to fail to reach or maintain an erection to satisfy sexual life. ED is divided into organic ED, psychological ED and mixed ED. Although ED is not fatal, it will seriously affect the quality of life between husband and wife, affecting the marital relationship.
  • Peripheral drug therapy mainly refers to the application of phosphodiesterase-5 inhibitors (such as: sildenafil), including papaverine, soluble guanylate cyclase activator, Rho kinase agonist and topical alprostadil Applications.
  • Central drug therapy refers to the treatment with drugs such as dopamine receptor agonists, alpha adrenergic receptor antagonists, serotonin (5- ⁇ ) receptor agonists, oxytocin and oxytocin receptor agonists.
  • Gene therapy is based on the fact that the ion channel is an important material basis for the regulation of the smooth muscle tone of the cavernous body.
  • the plasmid vector hMaxi-K (pVAX-hSLO) expressing the gene is injected into the cavernous body, and the plasmid is expressed in the smooth muscle of the cavernous body. More potassium channels allow the sponge to relax.
  • Phosphodiesterase-5 (PDE-5) inhibitor represented by sildenafil (Viaco) is the first-line treatment for ED, and it is also the most popular treatment method for patients.
  • PDE-5 inhibitors currently on the market include sildenafil (Sildenafil), vardenafil (Vardenafil), tadalafil, Udenafil, etc., as well as in clinical phase III.
  • Avanafil These drugs are taken orally, are easy to take, have a rapid onset of action, and are effective. Among them, sildenafil and tadalafil are important profitable products of Pfizer and Eli Lilly, respectively, and the market for such drugs is huge.
  • Sildenafil (Vardenafil) Avanafil Avanafil With the clinical application of PDE-5 inhibitors, some potential safety issues have surfaced, among which sildenafil While vardenafil has an inhibitory effect on PDE-5, it also has a certain inhibitory effect on PDE-6, and PDE-6 affects the function of the retina, so these two drugs will affect human vision, especially west. There are many reports from Dinnafil. Tadalafil has good selectivity for PDE-6, but it has a certain inhibitory effect on PDE-11. Although the clinical pharmacological effects of PDE-11 are unknown, there are still potential risks. There are reports in the literature about him. It can cause low back pain. Whether it is related to PDE-11 still needs to be verified.
  • tadalafil is too long, and the half-life in the human body is about 16 hours, which makes it easy for patients to take drug interactions while taking other drugs.
  • nitrate drugs can be combined with tadalafil, which will make patients The blood pressure is lowered too much, which in turn leads to life-threatening.
  • Avastatin belongs to the second generation of PDE-5 inhibitors, which have good selectivity for PDE-6.
  • the ratio of PDE-6/5 is about 120, and it does not inhibit PDE-11, which is clinical.
  • the safety of the drug is guaranteed, but the drug has poor enzymatic activity in vitro, and its clinical dose is high (50mg, 100mg and 200mg), higher than sildenafil, vardenafil and tadalafil.
  • the clinical use of patients also poses a certain safety hazard, and the increased dose will also lead to an increase in the cost of treatment. From the perspective of pharmacoeconomics, there is still much room for improvement in arvavir.
  • avonafil Because of its short half-life, avonafil has a half-life of about 1.2 hours and a short half-life. Therefore, it can only be used for single treatment of erectile dysfunction, and is not suitable for the treatment of BPH, OAB and other diseases. Therefore, the development of PDE-5 inhibitors with stronger pharmacological activity, higher safety, and suitable (longer but not too long) half-life is very important for improving the quality of life (treatment of ED and LUTS) in elderly patients.

Description

杂环取代的嘧啶类化合物
1、 技术领域
本发明属于医药技术领域, 具体涉及杂环取代的嘧啶类化合物、 其药学上可接受的盐或 其立体异构体, 这些化合物的制备方法, 以及这些化合物在制备增强 cGMP信号传导功能的 药物中的应用。
2、 背景技术
cGMP (鸟苷 -3',5'-环磷酸, 环磷酸鸟苷) 是一种环状核苷酸, 存在于动植物细胞中, 是 一种细胞内的第二信使, 参与广泛的细胞反应, 它能够被 PDE-5 (磷酸二酯酶 -5)水解, 当 PDE-5被抑制以后, cGMP的水平就会升高, 从而产生多种生理效应, 比如血管平滑肌舒张 等。 因此, PDE-5抑制剂可以用于 cGMP信号传导功能紊乱引起的疾病, 包括高血压、心力 衰竭、 肺动脉高压、 勃起功能障碍、 前列腺增生以及女性性功能障碍等多种疾病。
勃起功能障碍 (Erectile dysfunction, ED)是成年男子最常见的性功能障碍, 指阴茎持续不 能达到或者维持勃起以满足性生活的一种疾病。 ED分为器质性 ED、心理性 ED和混合性 ED。 ED虽不致命, 但会严重影响夫妻之间的生活质量下降, 影响夫妻感情。
ED的治疗方法很多, 主要包含三个方面: 外周药物治疗、 中枢药物治疗以及基因治疗。 外周药物治疗主要是指磷酸二酯酶 -5抑制剂 (比如: 西地那非)的应用, 还包括了罂粟碱、 可 溶性鸟苷酸环化酶活化剂、 Rho激酶激动剂和局部前列地尔的应用。 中枢药物治疗是指使用 多巴胺受体激动剂、 α肾上腺素能受体拮抗剂、 5-羟色胺 (5-ΗΤ)受体激动剂、催产素及催产素 受体激动剂等药物的治疗。 基因治疗是依据离子通道是海绵体平滑肌张力调节的重要物质基 础这一基础, 通过向海绵体内注射表达 ο基因的质粒载体 hMaxi-K (pVAX-hSLO), 该质粒 在海绵体平滑肌中表达, 产生更多的钾离子通道, 从而使海绵体舒张。
目前治疗 ED的方法很多, 以西地那非 (万艾可)为代表的磷酸二酯酶 -5(PDE-5)抑制剂是 治疗 ED的一线用药, 也是最受患者青睐的治疗方法。 目前已经上市的 PDE-5抑制剂包括西 地那非 (Sildenafil)、 伐地那非 (Vardenafil)、 他达拉非 (Tadalafil)、 乌地那非 (Udenafil)等, 以及 处于临床三期的阿伐那非 (Avanafil)。 这些药物口服吸收, 服用简便, 起效迅速, 疗效确切。 其中,西地那非和他达拉非分别为辉瑞和礼来公司的重要盈利产品, 可见这类药物市场巨大。
Figure imgf000003_0001
西地那非 (Sildenafil) 伐地那非 (Vardenafil) 阿伐那非 (Avanafil) 随着 PDE-5抑制剂的临床应用, 一些潜在的安全性问题也逐渐浮出水面, 其中, 西地那 非和伐地那非在对 PDE-5有抑制作用的同时, 对于 PDE-6也有一定的抑制作用, 而 PDE-6 影响视网膜的功能, 因此这两个药物会对人的视觉造成影响, 尤以西地那非的报道居多。 他 达拉非对 PDE-6有很好的选择性,但它对 PDE-11有一定的抑制作用,虽然 PDE-11的临床药 理作用未知, 但仍存在潜在的风险, 有文献报道他达拉非可以引起腰痛, 这与 PDE-11 是否 有相关性仍需考证。 另外, 他达拉非的半衰期过长, 人体内半衰期约为 16小时, 这很容易使 患者在服用其它药物的同时产生药物相互作用, 比如硝酸酯类药物与他达拉非合用, 会使患 者的血压降低过多, 进而导致生命危险。
阿伐那非属于第二代的 PDE-5抑制剂, 它对 PDE-6有着很好的选择性, PDE-6/5的比例 约为 120, 并且它不抑制 PDE-11 , 这就为临床用药的安全性提供了保证, 但这个药物体外酶 学活性差, 其临床给药剂量很高 (50mg, lOOmg和 200mg), 高于西地那非、 伐地那非和他 达拉非, 这对患者的临床用药也构成了一定的安全性隐患, 并且用药量增加, 还会导致治疗 成本增加, 从药物经济学角度来看, 阿伐那非还有很大的改良空间。
从流行病学角度出发, 很多老年男性患者在患有 ED的同时, 还有可能伴随其它的泌尿 生殖系统疾病, 比如良性前列腺增生症 (BPH)、膀胱过度活化 (OAB)等下尿路症状 (LUTS), 这 些疾病给老年患者带来了巨大的痛苦, 严重的影响着他们的生活。 通过病理学分析, ED与 LUTS 具有相同的发病机制, 都与平滑肌的收缩或者平滑肌细胞增殖有关, 因此, 通过使用 PDE-5 抑制剂, 完全有可能治疗具有相同发病机制的 LUTS , 目前已经上市的伐地那非 (Vardenafil)和他达拉非 (Tadalafil), 都在进行临床实验治疗 LUTS, 并且取得了明确的疗效。 阿伐那非由于其半衰期短, 人体内半衰期约为 1.2小时, 半衰期过短, 因此其只能用于勃起 功能障碍单一治疗, 不适合 BPH、 OAB等疾病的治疗。 因此, 研发具有更强的药理活性, 更 高安全性, 并且具有合适(较长但又不过长)半衰期的 PDE-5抑制剂, 对于改善老年患者的生活 质量 (治疗 ED和 LUTS)具有非常重要的意义。
3、 发明内容 本发明提供了一类安全性高、 活性强的 PDE-5抑制剂, 具体技术方案为, 通式 (I)所示的 化合物、 其药学上可接受的盐或其立体异构体:
