Definitions

  • the invention belongs to the field of medicine and relates to a novel fused ring-based azetidinyl triazole derivative, a preparation method thereof and a pharmaceutical composition containing the same and as a therapeutic agent, in particular as an oxytocin antagonist Uses and uses in the manufacture of a medicament for the treatment or prevention of a disease or condition known or capable of exhibiting a beneficial effect of inhibiting oxytocin.
  • Oxytocin is a cyclic nonapeptide that is normally synthesized by the hypothalamic paraventricular nucleus and released via the posterior pituitary. OT has a wide range of physiological functions, including social connections, sexual reproduction, and childbirth. OT exerts a physiological effect by binding to its oxytocin receptors (OTRs).
  • OTRs oxytocin receptors
  • Oxytocin modulators such as blockers or antagonists
  • Oxytocin modulators may be effective in treating abortion.
  • Studies have also shown that premature patients have higher oxytocin sensitivity and oxytocin receptor density than women of the same age. Therefore, the use of oxytocin receptor antagonists to block the action of oxytocin and its receptors is an important way to resist preterm birth.
  • Oxytocin modulators can also be used to improve the conception rate of patients receiving IVF embryo transfer, especially in patients with multiple unsuccessful transplant history.
  • Another condition associated with oxytocin is dysmenorrhea, which is characterized by pain and discomfort during menstruation. Oxytocin plays a role in the cause of dysmenorrhea due to its activity as a uterine vasoconstrictor (Akerlund et al., Ann. NY Acad. Sci. 734: 47-56, 1994). Oxytocin antagonists have a therapeutic effect on this condition.
  • oxytocin has been found to be one of the most potent substances that can induce penile erection in rats, rabbits and monkeys.
  • central administration of oxytocin is said to shorten the latency to ejaculation and shorten the post-ejaculation interval.
  • Meston et al. (Arch. Gen.
  • Psychiatry, 57(11): 1012-30, 2000 describe the injection of oxytocin into specific parts of the brain (ie, the paraventricular nucleus in the hypothalamus) in male animals.
  • the internal time can help the penis to erect and shorten the ejaculation latency and post-ejaculation interval when injected through the central or peripheral.
  • Oxytocin has also been successfully used to treat a patient with a sarcotic disorder. Inhalation of oxytocin through the nasal cavity can effectively restore ejaculation in patients who have previously failed to ejaculate during sexual intercourse (Ishak et al., J. Sex Med., 5(4): 1022-4, 2007).
  • Antagonists (or blockers) of oxytocin receptors have been shown to prolong the ejaculation latency of patients with premature ejaculation in clinical trials.
  • a selective oxytocin receptor antagonist IX-01, 400 mg or 800 mg in the second phase of clinical practice can significantly prolong the vaginal ejaculation latency of patients with premature ejaculation and improve the patient's self-perception (McMahon) , et.al., J. Urol., 197 (4S): e1344, 2017).
  • Another literature reported that in the ejaculation model of rats, a poorly cerebral oxytocin receptor antagonist (GSK557296) can only be effective when administered at specific central sites (intraventricular and intrathecal).
  • the oxytocin receptor is very similar to the structure of vasopressin receptors (including V1a receptor, V1b receptor, V2 receptor), in which V1a receptor and V2 receptor are mainly expressed in the periphery, which regulate blood pressure and kidney function, respectively.
  • V1b receptor is mainly expressed in the brain and pituitary gland, and controls the release of adrenocorticotropic hormone and ⁇ -endorphin. Therefore, for safety reasons, highly selective OTR agonists are also a key issue that must be considered in future developments (Alan D. Borthwick. J. Med. Chem. 2010, 53, 6525-6538).
  • OTR antagonists include: WO2005028452, WO2005082866, WO2006077496, WO2006092731, WO2006100588, and WO2006100557.
  • highly selective OTR antagonists remain the focus of development.
  • the inventors designed a compound having the structure represented by the general formula (I), and found that a compound having such a structure has a highly selective inhibitory effect on OTR, has good drug absorption, and has good brain permeability. Sexually, it can effectively block the downstream function of oxytocin receptor mediated by oxytocin.

Description

稠环基氮杂环丁基三唑类衍生物、其制备方法及其在医药上的应用 技术领域
本发明属于医药领域,涉及一种新的稠环基氮杂环丁基三唑类衍生物、其制备方法及含有该衍生物的药物组合物及其作为治疗剂,特别是作为催产素拮抗剂的用途和在制备用于治疗或预防已知或可显示抑制催产素会产生有益效应的疾病或病症的药物的用途。
背景技术
催产素(oxytocin;OT)是一种环状九肽,通常由下丘脑室旁核合成,并经由脑垂体后叶释放。OT具有广泛的生理功能,包括社会联系、有性生殖、分娩等。OT通过与其特异性受体(oxytocin receptors;OTRs)结合而发挥生理作用。
近年来,已经积累了有力的证据,表明催产素激素在引起哺乳动物特别是人的分娩中起主要的作用。通过“下调”催产素,预期可阻断催产素对子宫的直接(收缩)和间接(增加前列腺素合成)作用。催产素调节剂(如阻断剂或拮抗剂)对于治疗流产可能是有效的。也有研究表明早产患者比同孕龄妇女具有更高的催产素敏感性和催产素受体密度。因此,使用催产素受体拮抗剂阻断催产素与其受体的作用,是抗早产的一种重要途径。在试管婴儿胚胎移植的过程中,部分病人的子宫收缩会出现加剧的情况,并且和胚胎的着床成功率成负相关(Lan et al.,Reprod Biomed Online.25(3):254-60,2012)。因此,催产素的调节剂,也可用于改善接受试管婴儿胚胎移植的患者的受孕率,特别是有多次移植不成功病史的病人。另一种和催产素有关的状况是痛经,其特征为月经期的疼痛和不适。催产素在痛经的原因中起作用,其归因于其作为子宫血管收缩剂的活性(Akerlund et al.,Ann.NY Acad.Sci.734:47-56,1994)。催产素拮抗剂可对此病症具有治疗效应。
文献记载,在男性和女性体内,循环催产素水平会在性刺激和性唤起中增加,且在性高潮中达到最大值。如在Gimpl和Fahrenholz(Physiological Reviews 81(2):629-683,2001)中所详述,催产素经发现为可诱导大鼠,兔子和猴子阴茎勃起的最强力物质的一种。此外,中枢给予催产素据称会缩短到达射精的潜伏期及缩短射精后间隔。同样地,Meston等人(Arch.Gen.Psychiatry,57(11):1012-30,2000)述及在雄性动物体内,催产素在注射入脑的特定部位(亦即丘脑下部的室旁核)内时可帮助阴茎勃起且经中枢或外周注射时会缩短射精潜伏期和射精后间隔。催产素还被成功用于治疗一例性快感缺失症的病人,通过鼻腔吸入催产素,可使先前在性交中无法射精的病人,有效的恢复射精功能(Ishak et al.,J.Sex Med.,5(4):1022-4,2007)。而催产素受体的拮抗剂(或阻断剂),在临床实验中,显示出延长早泄病人的射精潜伏期的作用。一个处于临床二期阶段的选择性催产素受体拮抗剂IX-01,400毫克或800毫克,口服给予早泄病人后,可显著延长病人的阴 道内射精潜伏期,并可改善病人的自我感觉(McMahon,et.al.,J.Urol.,197(4S):e1344,2017)。另有文献报道,在大鼠的射精模型中,一个透脑性较差的催产素受体拮抗剂(GSK557296),只在特定中枢部位(脑室内及鞘内注射)给药时,才可有效的抑制大鼠的射精行为(Clement et al.,Br.J.Pharmacol.,169:1477-85,2013)。GSK557296在二期临床实验中,口服给药后也没有显示出相应的药效(Shinghal et.al.,J.Sex Med.,10:2506-17,2013)。因此,发现透脑性较好的催产素受体拮抗剂,是开发治疗早泄等射精功能障碍药物的关键。
催产素受体与加压素受体(包括V1a受体,V1b受体,V2受体)的结构非常相似,其中V1a受体和V2受体主要在外周表达,分别具有调节血压和肾脏功能。V1b受体主要在脑和下垂体中表达,可控制促肾上腺皮质激素和β-脑内啡的释放。因此,出于安全性的考虑,高选择性OTR激动剂也是以后开发中必须考虑的关键问题(Alan D.Borthwick.J.Med.Chem.2010,53,6525–6538)。
目前公开了一系列的OTR拮抗剂的专利申请,其中包括:WO2005028452、WO2005082866、WO2006077496、WO2006092731、WO2006100588和WO2006100557。但高选择性的OTR拮抗剂仍是开发的重点。经过不断努力,本发明人设计具有通式(I)所示结构的化合物,并发现具有此类结构的化合物对OTR具有高选择性抑制作用,药代吸收好,且具有较好的脑通透性,可有效阻断催产素所介导的催产素受体的下游功能。

3.1样品制备
用DMSO稀释药物化合物至50mM,得到储备液I;移取适量储备液I,用甲醇稀释得到200μM稀释储备液II;移取10μl储备液II于1.5ml Eppendorf管中,加入990μl空白血浆,混匀得到2μM血浆样品2(DMSO含量≤0.2%),用于该浓度血浆蛋白结合率的测定。移取上述配好的50μl血浆样品,记为T 0,置于-80℃冰箱保存待测。
3.2实验过程
取RED装置插入平衡透析管插至于96孔的底板中。取上述配制好的含待测物血浆样品2及相应空白血浆样品300μl,置于红色标记的孔中(plasma chamber)。取500μl pH 7.4磷酸缓冲盐溶液,置于并排红色标记的另一孔中(buffer chamber)。按上述步骤处理方法,每个化合物每一个浓度为2-3个样本。完毕用封条(sealing tape)覆盖96孔底板,并将整块底板放至热混仪中,以400rpm转速,于37℃平衡4h。孵化结束后,从热混仪中取出96孔底板装置,完成平衡透析。取50μl平衡后的血浆样品或透析液样品,加入50μl相对应的未平衡的不含药的空白磷酸盐缓冲液或不含药的空白血浆,加入内标(乙腈配制)300μl,涡旋混合5min,离心10min(4000rpm),取上清液进行LC/MS/MS分析。T 0样品不经孵化,直接采用上述建立的LC/MS/MS法分别测定总药物(plasma chamber)及游离药物(buffer chamber)与内标物色谱峰面积比,计算游离百分率(f u plasma%)。

血浆游离百分率(f u plasma%)=C buffer/C plasma×100%;
脑匀浆游离百分率(f u brain hom%)=C buffer/C brain hom×100%;
脑组织游离百分率(f u brain%)=f u brain hom/(Df-(Df-1)*f u brain hom)×100%;此处Df=11

3.实验方法和实验材料
3.1.实验动物和饲养条件
实验用SD雌性大鼠,40只,购自上海斯莱克实验动物有限责任公司(中国上海,许可证号SCXK(沪)2012-0002,合格证编号20150000541877),购入时180-200g,5只/笼饲养,12/12小时光/暗周期调节,温度23±1℃恒温,湿度50~60%,自由进食进水。动物购进后,进行适应性饲养后,开始实验。
3.2.动物分组:
SD大鼠适应性饲养后,分组如下:
组别 N 诱导剂 给药剂量 给药体积及途径
溶剂组 10 1μg/kg OT —— 6ml/kg,p.o.
化合物2-10mpk 10 1μg/kg OT 10mg/kg 6ml/kg,p.o.
化合物2-30mpk 10 1μg/kg OT 30mg/kg 6ml/kg,p.o.
化合物2-100mpk 10 1μg/kg OT 100mg/kg 6ml/kg,p.o.
注:p.o.为口服给药。
3.3.实验方法:
SD大鼠适应性喂养至合适体重后,随机分组如下:溶剂组、化合物2-10mpk、化合物2-30mpk和化合物2-100mpk。造模前1小时动物口服给药,给药后20min动物麻醉(20%乌拉坦8ml/kg麻醉),颈静脉插入PE导管以便静脉给药,管内充满生理盐水;腹部开口,结扎左侧靠近卵巢侧的子宫角,并在距离卵巢3cm处配线,切口,插入连有压力换能器的PE管,结扎后通过三通注入0.1ml生理盐水;连接多功能信号采集处理系统后,平衡压力后,在给药后1小时静脉给予1μg/kg OT,观察10-15min内的子宫压力变化。
3.4.数据统计
实验结束后,分别计算选取给予诱导剂前后5min子宫收缩压的曲线下面积(AUC),通过计算诱导前后曲线下面积差值与诱导前曲线下面积的比值,并与给予受试物后的比值的差值来判断受试物的药效作用。
△AUC比值=(AUC 0-AUC T)/AUC 0
AUC 0:诱导前曲线下面积;AUC T:诱导后曲线下面积。
4.结果
化合物2对OT诱导大鼠的子宫收缩模型的药效作用见图1。
5.结论
与溶剂对照组相比较,化合物2的30mpk和100mpk可有效阻断催产素所介导的催产素受体的下游功能(子宫收缩),子宫收缩模型能定量表征化合物的OTR拮抗活性。已有文献报道,男性大脑中的催产素受体与男性的射精功能有着紧密的联系。因此,在具有好的脑通透性的条件下,具有较强催产素受体拮抗功能的本发明化合物,能用于治疗男性性功能障碍。
