【背景技术】
香草素受体-1(VR1,或瞬时感受器电位香草素-1(transient receptor potential vanilloid-1),TRPV1)是辣椒中的刺激性成分辣椒碱(8-甲基-N-香草基-6-壬烯酰胺)的受体。TRPV1的分子克隆在1997年已有报道(Caterina等人,1997,Nature,389,pp816-824),其属于非选择性阳离子通道的TRP通道家族。TRPV1被诸如辣椒碱、仙人掌毒素、热、酸、花生四烯酸乙醇酰胺、脂质代谢物等的刺激物所激活或致敏;因此,其在哺乳动物中作为伤害性刺激的分子整合体(molecular integrator)起到关键性的作用(Tominaga等人,1998,Neuron,21 pp531-543;Hwang等人,2000,PNAS,97,pp6155-6160)。TRPV1高效表达于初级传入感觉神经元,而且有报道称还表达于各种器官和组织例如膀胱、肾、肺、肠、皮肤、中枢神经系统(CNS)、以及非神经元组织(Mezey等人,2000,PNAS,97,pp3655-3660;Stander等人,2004,Exp.Dermatol.13,pp129-139;Cortright等人,2001,BBRC,281,pp1183-1189),而且TRPV1蛋白在疼痛疾病情况下被上调。内源/外源性刺激物对TRPV1的激活不仅导致伤害性刺激的传递,而且还导致神经肽例如P物质、CGRP(降钙素基因相关肽)在神经元中的释放,由此诱发神经原性炎症。TRPV1敲除小鼠在包括伤害性机械刺激和急性热刺激的许多行为测试中表现出正常的应答,但是在炎症状态下几乎不表现热过敏性(thermal hypersensitivity)(Caterina等人,2000,Science,288,pp306-313;Davis等人,2000,Nature,405,pp183-187;Karai等人,2004,J.Clin.Invest.,113,pp1344-1352)。
如上所述,TRPV1敲除小鼠对热或伤害性刺激表现出降低的应答,这已得到TRPV1拮抗剂在各种动物疼痛模型中的作用的支持(Immke等人,2006,Semin.Cell.Dev.Biol.,17(5),pp582-91;Ma等人,2007,Expert Opin.Ther.Targets,11(3),pp307-20)。公知的TRPV1拮抗剂抗辣椒碱在数种炎性疼痛和神经性疼痛的模型中降低由物理性刺激导致的痛觉过敏(Walker等人,2003,JPET,304,pp56-62;Garcia-Martinez等人,2002,PNAS,99,2374-2379)。此外,用TRPV1激动剂辣椒碱等处理传入感觉神经元的原代培养物,导致神经功能的损伤以及神经细胞的死亡。TRPV1拮抗剂对此类神经功能的损伤以及神经细胞死亡起到防御作用(Holzer P.,1991,Pharmacological Reviews,43,pp143-201;Mezey等人,2000,PNAS,97,3655-3660)。TRPV1表达于分布在胃肠道的所有区域中的感觉神经元上,而且高度表达于炎性病症如肠易激综合征和炎性肠病中(Chan等人,2003,Lancet,361,pp385-391;Yiangou等人,2001,Lancet,357,pp1338-1339)。另外,激活TRPV1会刺激感觉神经,这又会导致神经肽的释放,已知所述神经肽在胃肠道病症例如胃-食管回流疾病(GERD)以及胃十二指肠溃疡中起到关键作用(Holzer P.,2004,Eur.J.Pharmacol.500,pp231-241;Geppetti等人,2004,Br.J.Pharmacol.,141,pp1313-1320)。
表达TRPV1的传入神经大量地分布在气道粘膜中,而且支气管过敏性与痛觉过敏具有非常相似的机理。质子和脂氧化酶产物已知是TRPV1的内源性配体,众所周知它们是发生哮喘和慢性阻塞性肺病的重要因素(Hwang等人,2002,Curr.Opin.Pharmacol.pp235-242;Spina等人,2002,Curr.Opin.Pharmacol.pp264-272)。另外,有报道称,空气污染物质(一类导致哮喘的物质),即颗粒物,特异性地作用于TRPV1,而且此类作用能够被抗辣椒碱抑制(Veronesi等人,2001,NeuroToxicology,22,pp795-810)。膀胱超敏(urinary bladder hypersensitiveness)和尿失禁是由各种中枢/周围神经病症或损伤导致的,而且在传入神经和膀胱上皮细胞中表达的TRPV1在膀胱炎症中扮演着重要的角色(Birder等人,2001,PNAS,98,pp13396-13401)。再者,TRPV1敲除小鼠在解剖学方面是正常的,但是与野生型小鼠相比,具有更高频率的、低幅度的、非排尿性的膀胱收缩,并且在膀胱充盈期间反射性排尿(reflex voiding)降低,这因此表明TRPV1影响膀胱的功能(Birder等人,2002,Nat.Neuroscience,5,pp856-860)。TRPV1分布在人表皮角质形成细胞以及初级传入感觉神经中(Denda等人,2001,Biochem.Biophys.Res.Commun.,285,pp 1250-1252;Inoue等人,2002,Biochem.Biophys.Res.Commun.,291,pp124-129),并且参与各种伤害性刺激以及疼痛如皮肤刺激和瘙痒的传递,由此与由神经原性/非神经原性因素导致的皮肤疾病和病症如皮肤炎症的病因具有密切的相关性。这得到以下报道的支持:TRPV1拮抗剂抗辣椒碱抑制人皮肤细胞中的炎性介质(Southall等人,2003,J.Pharmacol.Exp.Ther.,304,pp217-222)。在近几年中,已积累了关于TRPV1的其他作用的证据。TRPV1有可能通过感觉血管活性神经肽的释放参与血流/血压的调节,而且还参与血浆葡萄糖水平的调节或I型糖尿病的发病机理(Inoue等人,Cir.Res.,2006,99,pp 119-31;Razavi等人,2006,Cell,127,pp1123-35;Gram等人,2007,Eur.J.Neurosci.,25,pp213-23)。另外,有报道称,TRPV1敲除小鼠与其野生型同胞仔相比表现出更少的焦虑相关行为,在运动上没有差异(Marsch等人,2007,J.Neurosci.,27(4),pp832-9)。最近,还报道了TRPV1和肥胖症之间的关系。在这一报道中,饲喂高脂肪饮食时,TRPV1缺失小鼠比野生型具有降低的体重和肥胖(Motter等人,2008,FEBSlett.,582,pp2257-2262)。此外,有报道称表达TRPV1的神经在I型糖尿病(T1DM)中起作用并且小分子拮抗剂对TRPV1的阻断改善II型糖尿病(T2DM)的鼠模型中的胰岛素抵抗。(Suri等人,2008,Trends Pharmacol.l Sci.29(1),pp29-36;Gunthorpe等人,2008,Curr Pharm.Des.,14,pp32-41)。
基于上述信息,已有人正在研制各种TRPV1拮抗剂,而且一些涉及在研TRPV1拮抗剂的专利和专利申请已被公开(Szallasi等人,2007,Nat.Rev.Drug Discov.,6,pp357-72;Appendino等人,2006,Progress in Medicinal Chemistry,44,pp 145-180;Rami等人,2004,Drug Discovery Today:Therapeutic Strategies,1,pp97-104;Correll等人,2006,Expert Opin.Ther.Patents,16,pp783-795;Kyle等人,2006,Expert Opin.Ther.Patents,16,pp977-996)。

实验例:生物效力试验
1.45Ca内流试验
1)分离新生大鼠中的脊髓背根神经节(DRG)及其原代培养物
将新生(2-3天龄或少于2-3天龄)SD大鼠放入冰中5分钟进行麻醉,然后用70%酒精进行消毒。分割脊髓所有部分的DRG(Wood等人,1988,J.Neurosci.8,pp3208-3220),并收集在已加入1.2g/l碳酸氢钠和50mg/l庆大霉素的DME/F12培养基中。将DRG在37℃下分别于200U/ml胶原酶和2.5mg/ml胰蛋白酶中连续培养30分钟。这些神经节用添加有10%马血清的DME/F12培养基清洗2次,通过火烧光滑的Pasteur吸管进行研磨,用Nitex80膜过滤,得到单细胞悬浮液,然后再洗涤该悬浮液1次。将悬浮液离心,然后以特定的细胞密度水平重新悬浮于细胞培养基中。作为细胞培养基,将添加有10%马血清的DME/F12培养基用在汇合单层(1∶1)上的C6神经胶质瘤细胞调节2天的相同培养基稀释,然后添加NGF(神经生长因子)以调节至200ng/ml的最终浓度。细胞在为了杀死分化的非神经元细胞而添加有阿糖胞苷(Ara-C,100μM)的培养基中生长2天后,将培养基换成不含Ara-C的培养基。将重新悬浮的细胞在预先用10μg/ml多聚-D-鸟氨酸包被的Terasaki板上以1500-2000个神经元/孔的密度进行铺板。
2)45Ca内流实验
通过用HEPES(10mM,pH 7.4)缓冲的无Ca2+、Mg2+的HBSS(H-HBSS)洗涤4次,来平衡来自2天的原代培养物的DRG神经细胞。从各个孔中除去每个孔中的溶液。向每个孔中添加包含受试化合物的培养基以及在H-HBSS中的辣椒碱(最终浓度0.5μM)和45Ca(最终浓度10μCi/ml),然后在室温下温育10分钟。将Terasaki板用H-HBSS洗涤5次并在室温下干燥。向每个孔中添加0.3%SDS(10μl)以洗脱45Ca。在向每个孔中添加闪烁鸡尾酒后,通过计数放射活性来测量进入神经元的45Ca内流的量。受试化合物对香草素受体的拮抗活性以浓度为0.5μM的辣椒碱的最大应答的抑制百分数来计算。结果示于表1中。

2.镇痛活性试验:由苯基对苯醌诱发的小鼠扭体试验
将雄性ICR小鼠(平均体重25g)保持在受控的照明环境(12小时开/12小时关)中用于实验。动物接收腹膜注射0.3ml的化学刺激剂苯基对苯醌(溶解在包含5%乙醇的盐水中,以形成4.5mg/kg的剂量)并在6分钟后,在随后6分钟的时间内计数腹部收缩的数量。在注射苯基对苯醌前30分钟,动物(10只动物/组)通过腹膜给药接受0.2ml受试化合物在载体乙醇/Tween 80/盐水(10/10/80)中的溶液。在口服给药的情况下,在注射0.2ml的0.02%苯基对苯醌之前54分钟时给药0.2ml受试化合物在载体乙醇/Tween 80/盐水(5/5/90)中的溶液。相对于盐水对照组中的响应数量,响应受试药物化合物的扭体数量的减少被视作镇痛作用的指示。镇痛作用根据%抑制等式(%抑制=(C-T)/C x 100)来计算,其中C和T分别表示对照组和化合物治疗组的扭体数量。对于苯基对苯醌(给药途径(P.O.))引起的扭体的镇痛活性的试验结果显示于表2。
