Abstract
本发明公开了一种异苯并二氢吡喃类化合物及其药物组合物和应用。该化合物结构如式I,还包含其药学上可接受的盐,其可有效阻断α1‑受体(在微摩尔浓度水平甚至纳摩尔浓度水平的体外抑制率达到100%,IC50值最优低于5nM),而且对α1A‑受体的选择性更优,体内低剂量即可显现明显药效;应用广泛,可制备为能够有效治疗前列腺增生、膀胱过度活动症或高血压的药物。化合物制备方法便捷易操作、适于多种结构类型。
Description
技术领域
本发明涉及一种异苯并二氢吡喃类化合物及其药物组合物和应用,尤其涉及一种可制备为具有优异的选择性阻断活性的α1-受体拮抗剂药物的异苯并二氢吡喃类化合物及其药物组合物和应用。
背景技术
良性前列腺增生(benign prostatic hyperplasia,BPH)是一种中老年男性排尿功能障碍疾病,其主要表现为前列腺间质和腺体增生、前列腺增大,出现下尿路症状及膀胱出口梗阻等症状,排尿频率增加、排尿急迫性增加及夜间排尿增加、排尿疼痛、不畅、不全和溢流性尿失禁,严重影响患者的生活质量。
前列腺增生通过两种主要机制引发尿路梗阻。第一种机制是前列腺间质的增加导致结节性增大,进而导致前列腺尿道扭曲和尿路阻塞。第二种机制是前列腺和膀胱颈的平滑肌张力增加,这是由α1肾上腺素受体介导的。α1-受体拮抗剂能够阻断前列腺和膀胱颈部的α1肾上腺素受体,从而缓解梗阻。一些α1-受体拮抗剂,如坦索罗辛和西罗酮,通过对位于前列腺和膀胱颈的α1A-受体肾上腺素受体具有高亲和力而表现出尿路选择性。
肾上腺素受体存在于许多器官系统中,包括泌尿生殖道、胃肠道、血管系统和虹膜。因此,α1-受体拮抗剂的使用与全身不良反应相关,尤其是体位性低血压,鼻腔充血是由α1-受体拮抗剂的血管舒张作用引发的另一种不良反应。同时“虹膜松弛综合征”是泌尿科医生经常忽视的特殊不良反应症状,当患者进行白内障手术时,可能会影响围手术期的治疗效果。此外由于一些α1-受体拮抗剂是尿路选择性的,如坦索罗辛和西罗酮,对泌尿生殖道中常见的α1A肾上腺素受体具有优先拮抗作用。理论上认为它们应该比其他α1-受体拮抗剂更安全,然而由于其在下尿路的集中作用,引发的射精功能障碍更为常见。
以往治疗前列腺增生的可选药物是有限的,药物只能提供短期的症状缓解,而且具有显著的不良反应。其中一个例子是苯氧基苯丙胺,一种非选择性不可逆的α-受体拮抗剂。在症状缓解的几个小时内,患者有体位性低血压、轻度头痛、昏厥和反复跌倒的风险。由于对前列腺增生的进展缺乏有效的控制,许多患者尽管服用了多年的药物,最终还是会出现并发症或需要手术干预。

实施例31:片剂的制备
按照上述处方,采用常规方法混合、制粒、干燥、整粒、压片,共制备成片剂100片。
实施例32:化合物对α1-受体的抑制活性
1、实验原理
通过建立了共转目标受体和Gα16的细胞系,使得受体被激活后能引起Gα16蛋白的活化,进而激活磷脂酶C(PLC)产生IP3和DAG,IP3可与细胞内内质网和线粒体上的IP3受体结合,从而引起胞内钙的释放。因此,测定胞内钙的变化可以作为检测目标受体活化状态的方法。Fluo-4/AM是一种钙荧光探针指示剂用来测量钙离子,作为非极性脂溶性的化合物,进入细胞后在细胞脂解酶的作用下,AM基团解离,释出Fluo-4;由于Fluo-4是极性分子,不易通过脂质双分子膜,它可使Fluo-4长时间保留在细胞内。最终可以通过测量被激发的荧光强度来反映Gα蛋白被激活的水平。如果筛选的化合物能够激动目标受体,则可以使钙流反应大大升高。反之,如果筛选的化合物能够拮抗目标受体,则可以使钙流反应大大降低。
