Description
发明领域
本发明涉及苯基杂烷基胺衍生物用作一氧化氮合酶抑制剂方面的用途。同时也公开了某些新型苯基杂烷基胺衍生物及其制备方法,含有这些苯基杂烷基胺衍生物的组合物以及它们的治疗用途。
发明背景
一氧化氮是在哺乳动物细胞中在特定一氧化氮合酶(NOS)的作用下由L-精氨酸产生的。这些酶分成两种不同的种类:组成型NOS(cNOS)和诱导型NOS(iNOS)。目前,已经鉴别出两种组成型NOS和一种诱导型NOS。在组成型NOS中,内皮酶(ecNOS)涉及到平滑肌松弛和血压与血流调整,而神经元酶(ncNOS)则用作神经递质并且好象涉及多种生物机能如大脑局部缺血的调整。已经有人特别指出,诱导NOS牵涉到炎症性疾病的发病。因此对这些酶的调整在多种疾病的治疗中具有相当的潜力(J.E.Macdonald,Ann.Rep.Med.Chem.,1996,31,221-230)。为了鉴别那些能作为一氧化氮合酶的一种或多种异构形式的特定抑制剂的化合物,人们已经进行了相当的努力。这种化合物在治疗中的用途也已经被广泛要求过专利权。
U.S.专利4 902 710公开了具有如下化学式的新型化合物:
其中R1表示苯基,取代苯基、C5-7环烷基、噻吩基、卤代噻吩基,(C1-4烷基)-取代噻吩基、呋喃基、吡啶基或噻唑基;R2和R3彼此独立地为氢或甲基;n为0、1或2;在其它基团中,R可以是取代苯基。所述化合物是血清素和去甲肾上素摄取的有力和选择性的抑制剂,并且因此被宣称在治疗人体疾病如焦虑、沮丧和肥胖中是有用的。
本发明涉及一个令人惊奇的发现,即,一组苯基杂烷基胺衍生物,包括属于U.S.4 902 710一般范围内的一些化合物是一氧化氮合酶的抑制剂。

当然,对于上述治疗适应症来说,给药剂量将随所使用化合物、给药方式和所要治疗的疾病的不同而变化。但是,一般来说,当化合物的给药剂量为每天1mg-2000mg(固态)时会取得令人满意的结果。

为进行试验,将25μl的底物混合物(50mM Tris-HCl(20℃下的pH为7.5),400μM NADPH,20μM黄素腺嘌呤二核苷酸,20μM黄素单核苷酸,4μM四氢生物蝶呤,12μML-精氨酸和0.025mCi L-[3H]精氨酸)加入到一个96孔滤板(孔径为0.45μM)的孔中,其中装有25μl溶液,该溶液是由测试化合物溶于50mM Tris-HCl中形成的。通过加入50μl细胞溶菌产物(如上制备)开始反应,在室温下培育1小时后,加入50μl的3mM硝基精氨酸和21mM EDTA的水溶液终止反应。
使用Dowex AG-50W将标记的L-瓜氨酸与标记的L-精氨酸分离,在试样中加入150μl 25%的Dowex 50W(Na+形式)含水浆液,随后全部过滤进入96孔板。75μl滤液作为样品并加入到装有固体闪烁材料的96孔板容器中。使得样品干燥后,通过闪烁计数将L-瓜氨酸定量。
在一个标准的实验中,每75μl样品的基底活性为300dpm,而在对比试剂中,该值增加到1900dpm。将化合物活性用IC50来表示(试验中形成50%酶抑制的药物浓度),将氨基胍,其IC50(50%抑制浓度)为10μM,作为标准物进行测试来校验所述方法。化合物在一定范围的浓度下进行测试,并从得到的抑制结果计算IC50值。在100μM下抑制酶至少25%的化合物列为活性物,并对其进行至少一次重复试验。
筛选2
在下面的试验中,可以证明化合物对于诱导的一氧化氮合酶的人型也显示出活性。
诱发后,从培养的人体结肠腺癌细胞系DLD1(得自EuropeanCollection of Animal Cell Culture-细胞素号为90102540)制备酶。DLD1细胞培养在补充有10%胎牛血清,4mM L-谷氨酸盐和抗生素(100单位/毫升青霉素G、100μM/ml链霉素和0.25μM/ml两性霉素B)的RPMI1640介质中。细胞通常在含有35ml介质的225cm3烧瓶中成长,所述介质保持在37℃,含有5%CO2的湿润气氛中。
一氧化氮合酶由对干扰素-γ(IFN-γ)和白细胞间介素-1β(IL-1β)有响应的细胞产生。除去铺满培养瓶中的介质,并用25ml(每烧瓶)含有250单位/ml IL-1β和1000单位/ml IFN-γ的新鲜介质代替。培养17-20小时后,通过将烧瓶表面的细胞单层刮到培养介质中而收集细胞。通过离心法(每10分钟1000克)收集细胞,通过把细胞离心团块加入包括50mM Tris-HCl(20℃下的pH为7.5),10%(v/v)甘油,0.1%(v/v)Triton-X100,0.1mM二硫苏糖醇以及蛋白酶抑制剂混合物的溶液来制备溶菌产物,所述蛋白酶抑制剂混合物包括亮抑酶肽(2μM/ml),黄豆胰蛋白酶抑制素(10μM/ml),抑酶肽(5μM/ml)和苯基甲基磺酰氟(50μM/ml)。
为进行试验,将25μl底物混合物(50mM Tris-HCl(pH7.5)、400μM NADPH、20μM黄素腺嘌呤二核苷酸、20μM黄素单核苷酸和4μM四氢生物蝶呤)加入到96-孔板的孔中。通过将测试化合物与40μl细胞溶菌产物(如上制备)加在一起并在37℃培育1小时来进行预培养,1小时结束时,加入10μl的30μM L-精氨酸和0.025μCi的-L[3H]-精氨酸的50mM Tris-HCl溶液,开始酶促反应。在37℃下再继续培养1小时,通过加入50μl的3mM硝基精氨酸和21mM EDTA的水溶液终止反应。
使用Dowex AG-50W将标记的L-瓜氨酸与标记的L-精氨酸分离。将120μl 25%的Dowex 50W含水浆液加入到96孔滤板中(孔径0.45μm)。向其中加入120μl终止的试验混合物。75μl滤液作为样品并加入到装有固体闪烁材料的96孔板的孔中。使得样品干燥后,通过闪烁计数将L-瓜氨酸定量。
在一个标准的实验中,每75μl对比试剂的基本活性为300dpm,但当酶存在时该值增加到3000dpm。将化合物活性用IC50来表示(试验中产生50%酶抑制的药物浓度),用L-NMMA,其IC50(50%抑制浓缩)为约0.4μM,作为标准物进行测试以校验所述方法。化合物在一定范围的浓度下进行测试,并从得到的抑制结果计算IC50值。
测试时,在至少一个上述筛选中,实施例1-16化合物的IC50值低于15μM,这表明可以预测它们具有有效的治疗活性。
