  • the present invention relates to a pharmaceutical use of a hexahydrodibenzo[a,g]quinolizin compound, and in particular to its use in the manufacture of a medicament for the treatment and/or prevention of benign prostatic hyperplasia.
  • Benign prostatic hyperplasia is a common physiological disease in middle-aged and elderly men. With the inevitable population aging, the incidence of benign prostatic hyperplasia has been greatly improved compared with the previous one. It has become a middle-aged male in China. One of the most common geriatric diseases. Data show that prostatic hyperplasia is very low before the age of 40, and about half of men over the age of 50 have benign prostatic hyperplasia, and nearly 90% of those aged 80 have the disease. Benign prostatic hyperplasia is a benign adenomatous hyperplasia of cells in the peri-urethral region of the prostate.
  • prostate hyperplasia is one of the common diseases in domestic and foreign middle-aged men, which greatly reduces the quality of life of patients.
  • the pathogenesis of benign prostatic hyperplasia is complex and related to a variety of enzymes and receptors.
  • the two most widely used drugs for the treatment of BPH are 5 ⁇ -reductase inhibitors and ⁇ -adrenergic receptor antagonists, which are respectively aimed at the prostate volume and smooth muscle tone which cause symptoms of benign prostatic hyperplasia. for treatment.
  • the 5 ⁇ -reductase inhibitor inhibits the conversion of testosterone to dihydrotestosterone in the body, thereby reducing the content of dihydrotestosterone in the prostate, thereby achieving the therapeutic goal of reducing the volume of the prostate and improving dysuria.
  • this class of drugs is only suitable for the treatment of patients with sputum with enlarged prostate volume and lower urinary tract symptoms, and often accompanied by erectile dysfunction, ejaculation abnormalities, low libido and other side effects such as feminization of male breasts and breast pain. Therefore, it is clinically most widely used as ⁇ -adrenergic receptor antagonists.
  • Adrenergic receptors are classified into ⁇ -receptors and ⁇ -receptors, and ⁇ -adrenergic receptors ( ⁇ -ARs) are divided into two types of receptors, ⁇ and a 2 , which have been identified. a subtype of three a r receptors of a 1A , a 1B and a 1D . Studies have shown that there are mainly receptors in the matrix components and glandular epithelium of the prostate, where a 1A -ARs account for about 70% of the total a r ARs in the prostate and urinary tract.
  • a 1A -receptors are mainly distributed in the prostate, urethra and bladder triangle, vas deferens, a 1B -receptor distributed in blood vessels, and a 1D -receptor distributed in bladder detrusor and ureter smooth muscle.
  • a r ARs In the pathological condition of BPH, the density of a r ARs increased significantly. In addition, the distribution of a r ARs subtypes varies with age. This age-related distribution has an understanding of and treatment of benign prostatic hyperplasia and lower urinary tract system symptoms, and the development of ⁇ -adrenergic receptor antagonists. Significance. The a 1A -adrenergic receptor is considered to be an ideal target for the treatment of benign prostatic hyperplasia, and its blockade has been shown to be effective in reducing the contractile frequency of prostate smooth muscle and improving bladder emptying.
  • Blocking of the a 1B -adrenergic receptor can lead to vascular smooth muscle relaxation, arteriovenous dilatation, and reduced peripheral resistance, which may cause side effects such as dizziness and hypotension in some patients.
  • Activation of a 1D -adrenergic receptors can lead to hyperactivity of the detrusor, which can reduce the occurrence of emptying symptoms, which has been confirmed in animal experiments.
  • a combination of a 1A and a 1D -adrenergic receptors is very effective in controlling benign prostatic hyperplasia. Effective drugs. Because it contains the function of reducing the frequency of contraction of the smooth muscle of the prostate and inhibiting the detrusor dysfunction, in addition to avoiding the cardiovascular side effects caused by the ⁇ 1 ⁇ -adrenergic block.
  • Phenoxybenzamine An irreversible non-selective ⁇ / ⁇ 2 receptor blocker of phenoxybenzamine ⁇ -haloalkanes, which blocks alpha receptors in the prostate and relaxes fibrous tissue of the prostate. It is clinically used to treat non-mechanical diseases caused by the prostate. Difficulties in urination caused by sexual urethral obstruction.
  • the phenoxybenzamine structure contains a ⁇ -chloroethylamine structure, which is easily reacted with other enzymes in the body, so that toxicity and side effects are more.
  • phenoxybenzamine blocks the presynaptic ⁇ 2 receptor while blocking the 04 receptor, so that feedback releases norepinephrine at the nerve endings, causing reflexivity.
  • Side effects such as tachycardia and irregular heartbeat.
  • ⁇ -adrenergic receptor antagonist with high selectivity for ⁇ receptor has emerged (eg: prazosin, terazosin, doxazosin, alfuzosin) ;).
  • a r adrenergic receptor can alleviate contraction of prostatic and urethral smooth muscle caused by the sympathetic nerve, alleviating the symptoms of urethral obstruction from dynamics.
  • These drugs are effective in relieving the symptoms of lower urinary tract while reducing the side effects caused by vasodilation.
  • the oxazinoids have the structural nucleus of quinazoline and are currently commonly used in the clinical treatment of BPH and its lower urinary tract symptoms (LUTS).
  • LUTS lower urinary tract symptoms
  • the drugs listed for the treatment of benign prostatic hyperplasia are a 1A receptor selective antagonists, namely Tamsulosin and Silodosin.
  • Tanluo Xin is considered to be ⁇ 1 ⁇ receptor selective antagonists, however it ⁇ other less selective receptor, as listed earlier are very much in market share. But it still has some side effects, such as side effects in the immune system and the eye, as well as side effects such as ejaculation disorders, blood pressure lowering, and headaches.
  • the soon-to-market drug, silodosin has better receptor selectivity and its selectivity is significantly better than tamsin, so its clinical side effects are significantly less than tamsulosin. Therefore, the development of drugs with better ⁇ 1 ⁇ receptor selectivity undoubtedly has a good market prospect for the treatment of benign prostatic hyperplasia. Summary of the invention

Description

一种六氢二苯并 ia,gl喹嗪类化合物的药物用途
技术领域
本发明涉及一种六氢二苯并 [a,g]喹嗪类化合物的药物用途, 具体涉及其在制 备治疗和 /或预防良性前列腺增生疾病的药物中的用途。 背景技术
良性前列腺增生 (benign prostatic hyperplasia, BPH)是中老年男性常见的生理 病变, 随着不可避免的人口老龄化, 良性前列腺增生的发病率较以前相比有大幅 度的提高, 已成为我国中老年男性最常见的老年病之一。 资料显示, 前列腺增生 在 40岁以前发病率很低, 而在 50岁以上男性中约有一半患有良性前列腺增生, 80岁者近 90%患有该病。 良性前列腺增生是前列腺尿道周围区细胞的良性腺瘤性 增生, 腺体的进行性肿大可使前列腺尿道狭窄, 引起膀胱尿液流出梗阻, 最初临 床表现为下泌尿道系统症状 (; Lower urinary tract symptoms, LUTS), 最终可发展为 尿潴留、 膀胱感染、 膀胱结石和肾衰竭, 甚至会危及患者的生命。 因此, 前列腺 增生作为国内、 外中老年男性的常见疾病之一, 极大地降低了患者的生活质量。
良性前列腺增生的发病机制比较复杂, 与多种酶和受体有关。 目前, 临床上 用于治疗 BPH应用最广泛的两种药物分别是 5α-还原酶抑制剂和 αι-肾上腺素受体 拮抗剂, 分别针对造成前列腺增生症状的前列腺体积和平滑肌张力这两个因素进 行治疗的。 5α-还原酶抑制剂通过抑制体内睾酮向双氢睾酮的转变, 进而降低前列 腺内双氢睾酮的含量, 达到缩小前列腺体积、 改善排尿困难的治疗目的。 但是该 类药物只适用于治疗有前列腺体积增大伴下尿路症状的 ΒΡΗ患者,而且常伴有勃 起功能障碍、 射精异常、 性欲低下和其他如男性乳房女性化、 乳腺痛等副作用。 因此, 临床上又以 αι-肾上腺素受体拮抗剂应用最多。
肾上腺素受体 (adrenergic receptors, ARs)分为 α-受体和 β-受体, α-肾上腺素 受体 (α-ARs)又分 αι、 a2两种类型的受体, 目前已经确定有 a1A、 a1B禾卩 a1D三种 ar 受体的亚型。 研究表明, 在前列腺的基质成分和腺管上皮中主要存在 (^型受体, 其中 a1A-ARs约占人体前列腺及尿路系统中总 arARs的 70%。在生殖、泌尿系统, a1A -受体主要分布在前列腺、 尿道和膀胱三角区、 输精管, a1B -受体分布在血管, a1D-受体分布在膀胱逼尿肌和输尿管平滑肌。
在 BPH病理情况下, arARs密度明显增加。 此外, 随着年龄的变化 arARs 亚型的分布特点也不同, 这种年龄与分布的相关性对了解和治疗良性前列腺增生 及下泌尿道系统症状, 开发 αι-肾上腺素受体拮抗剂具有重要意义。 a1A -肾上腺素 受体被认为是治疗良性前列腺增生的理想靶点, 对它的阻断已经被证明可以有效 减少前列腺平滑肌的收缩频率, 同时改善膀胱的排空。 对 a1B -肾上腺素受体的阻 断可以导致血管平滑肌舒张, 动静脉扩张, 外周阻力减少等症状, 可能在某些病 人身上引发副作用, 诸如头晕和低血压。 a1D-肾上腺素受体的激活能导致逼尿肌 的活动过度, 对其阻滞可以减少排空症状的发生, 这已经在动物试验中得到了证 实。 理论上 a1A和 a1D -肾上腺素受体的联合抑制剂是控制良性前列腺增生非常有 效的药物。 因为它包含减少前列腺平滑肌收缩频率和抑制逼尿肌功能失调两项功 能, 此外又可避免 α -肾上腺素受体阻滞所引起的心血管的副作用。
第一代被开发利用并能够有效减缓良性前列腺增生症状的 α受体阻断剂是酚 苄明 (Phenoxybenzamine;)。 酚苄明属 β-卤代烷类不可逆的非选择性 αι2受体阻断 剂, 能阻断前列腺中的 α受体, 使前列腺体纤维组织松弛, 临床上用于治疗前列 腺引起的非机械性尿道梗阻导致的排尿困难。 酚苄明结构中含有 β-氯乙胺结构, 它在体内易与其他酶发生反应, 故毒性和副作用较多。 而且作为非选择性 α受体 阻断剂, 酚苄明在阻滞 04受体的同时阻滞突触前 α2受体, 故反馈性地引起神经末 梢释放去甲肾上腺素, 从而引起反射性心动过速、 心律不齐等副作用。
为了减少这些副作用, 针对 αι受体具有高选择性的第二代 αι-肾上腺素受体 拮抗剂应运而生 (;如: 哌唑嗪, 特拉唑嗪, 多沙唑嗪, 阿夫唑嗪;)。 ar肾上腺素受 体可以缓解由交感神经引起的前列腺和尿道平滑肌的收缩, 从动力学方面减轻尿 道梗阻的症状。 这些药物在有效缓解下尿路症状的同时减少了因血管扩张导致的 副作用的产生。 唑嗪类药物都具有喹唑啉的结构母核, 是目前临床上治疗 BPH及 其引起的下尿路症状 (LUTS)的常用药物。 然而由于 αι -肾上腺素受体的广泛分布 和重要生理功能, 使用 αι -肾上腺素受体拮抗剂常会出现体位性低血压、 头晕、 无 力等副作用。
近几年上市治疗良性前列腺增生的药物为 a1A受体选择性拮抗剂, 分别为坦 洛辛 (Tamsulosin)和西洛多辛 (Silodosin)。虽然坦洛辛被认为是 α受体选择性拮抗 剂, 然而它对其它 αι受体选择性较差, 由于上市较早目前市场占有量很大。 但它 仍然有一些副作用, 比如免疫系统及眼部方面的副作用, 此外还有射精障碍、 血 压降低、 头疼等副作用。 才上市不久的药物西洛多辛具有较好的受体选择性, 其 选择性明显优于坦洛辛, 因此目前其在临床上的副作用也明显少于坦洛辛。 因此, 开发具有较好的 α受体选择性的药物对于良性前列腺增生的治疗无疑是具有较 好的市场前景的。 发明内容

化合物 DC037009对去甲肾上腺素诱导尿道平滑肌收缩有明显的拮抗作用, IC50 = 1.66 nM, 并显著强于对去甲肾上腺素诱导的血管平滑肌收缩的抑制作用, 受体选择比达到 873, 并且尿道抑制率与阳性药相当。 DC037009选择性优于阳性 药坦洛新和西洛多辛, 是坦洛新的 1617倍, 是西洛多辛的 11倍, 对于减少现有 药物存在的副作用十分重要。 实施例 4: 药理学研究
雄性 SD大鼠, 体重 250-450 g, 乌拉坦 (1.2 g/kg)腹腔注射麻醉。 沿腹白线作 一至耻骨联合处切口, 使膀胱、 前列腺、 尿道暴露。 再用一导管由膀胱穹隆部插 入尿道前列腺处, 并用缝合线固定于膀胱颈部 (膀胱尿道联合处)。 闭合耻骨下远 端尿道。导管的另一端连接压力感受器, 以测量尿道内压力 (IUP)。分离十二指肠, 距胃幽门部约 2cm切开、 插管行荷包缝合, 供给受试样品。 另外行颈正中切口, 分离颈总动脉, 插管连接动脉压力换能器测定动脉血压, 在整个操作过程中注意 勿伤及神经和血管。 在手术结束后, 注射少量 (0.1~0.2 mL)生理盐水使尿道内压力 大约平衡在 10 cm水柱。 然后于给药前、 给药后 5 min、 30 min、 1 h、 1.5 h、 2 h、 3 h(如作用稳定或减弱结束实验;)静脉推注浓度为 30 g/mL 的盐酸苯肾上腺素 (PHE)l mL/kg诱导尿道内压升高, 观察并记录给药前后不同时间点苯肾上腺素引 起的大鼠尿道内压和外周动脉基础血压的变化。
实验结果表明西洛多辛、 DC037009 能剂量依赖性地抑制苯肾上腺素诱导的 尿道内压 (IUP)和外周动脉压 (MBP)的升高。 其抑制苯肾上腺素诱导尿道内压增加 作用为: DC037009>西洛多辛; 抑制苯肾上腺素诱导血压升高作用依次为: 西洛 多辛 >DC037009;对尿道的选择性分别为: DC037009>西洛多辛。此外, DC037009 起效剂量明显低于阳性药 Silodosin (;见图 1和图 2)。 实施例 5: 药效学实验
BPH大鼠模型的建立: 6周龄 SD雄性大鼠 49只 (体重 200g左右) , 其中 37只做为 BPH模型组。 每天腹部皮下注射丙酸睾酮, 另外 12只做为 Sham组注 射橄榄油, 持续 4周。 4周后, 49只大鼠按 30mL/kg水的剂量灌胃, 观察并记录 每只大鼠的排尿情况 (记录每次排尿量和 2小时内排尿次数) 。
根据以上验证结果, 首先剔除排尿情况不正常的大鼠, 然后将状态正常 BPH 模型组大鼠分为 2组, 每组 12只, Sham组挑出 12只作为对照组。 分组的原则是 力求 2组 BPH模型组分别与 Sham组在体重、 2小时内的排尿次数、 单次排尿量 以及排尿总量上相比呈显著性差异, 并且 BPH模型组 2组之间没有显著差异。 实 验结果表明, 两组 BPH模型大鼠均与 Sham组体重及两小时内排尿次数、 单次排 尿量有显著差异, 而排尿次数与总排尿量没有差异 (图 3 ) 。
药效验证实验: 本实验共分 7组: Sham组、 Silodosin组 (BPH-1,3组剂量)和 DC037009组 (BPH-2,3组剂量)。 CMCNa溶解的各剂量化合物以 5mL/kg大鼠灌胃, 20min后各组大鼠以 30mL/kg水负荷灌胃。 同一种化合物不同剂量研究时间间隔 大于 24小时。
Silodosin和 DC037009组大鼠的排尿次数、单次排尿量均呈现剂量依赖关系,
DC037009与阳性药 Silodosin药效相当, 起效剂量为 lmg/kg。 药效学实验证明化 合物 DC037009可以在总排尿量一定的情况下, 显著增加单次排尿量, 减少排尿 次数 (图 4 ) 。 实施例 6: 药代动力学研究
