生物测试
将式(I)的化合物如下测试各种活性:
筛查策略:
设计筛查策略以选择具有合适钠通道阻滞活性和低的副作用倾向的化合物。为此目的,将所有化合物通过初步钠通道检测(藜芦碱诱发的[14C]胍进入大鼠的前脑突触体的摄取)来处理,并从产生的浓度影响曲线计算IC50值。为了完成此数据,还测量选择的化合物抑制[3H]BTX-B结合的IC50’s。
之前的研究显示:取代的三嗪为双氢叶酸还原酶(DHFR)活性的潜在抑制因子(McCullough和Bertino1971,Cashmore等人,1975,Booth等人,1987)和Sapse等人,1994)。DHFR(例如甲氨蝶呤)的抑制因子已用于治疗各种癌症(Suster等人,1978和Niculescu-Duvaz等人,1982),因为该酶的抑制作用干扰细胞生长,但是因为此影响(对于细胞生长),DHFR的抑制因子也可能产生畸形(Skalko和Gold,1974,Feldcamp和Carey,1993及Buckley等人,1997)。应发现为DHFR的潜在抑制因子的化合物,然后此化合物本身可能具有作为抗癌剂的潜力。几种方法可用于测量DHFR活性的抑制,为了此研究,我们已检测化合物抑制[3H]甲氨蝶呤的结合的效果(Myers等人,1975和Rothenberg等人,1977)。
另一通常的副作用标记为人类Ether-a-go-go相关基因(hERG)钾通道(内向整流,Ikr)活性的抑制,这可能是致命的,因为通过长QT综合症的发展导致心力衰竭。有用的初步筛查通过测量[3H]阿斯咪唑(astemizole)结合至细胞膜表达hERG的抑制来评价,以评价影响此通道的潜在性。通过测量在10μM下的抑制来测试选择的化合物的该活性。假定抑制值位于10%和90%之间,可以计算各化合物的外推IC50。
上述筛查级联(cascade)鉴别了具有合适钠通道阻滞活性的化合物,所述化合物具有(较)低的前述副作用倾向。为了进一步开发这些化合物,需要一些它们药效性药理作用的知识。
钠通道阻滞剂,例如在大鼠中中脑动脉阻塞后降低神经损伤和梗塞体积的西帕曲近(Sipatrigine)(Smith等人,1997),以及苯妥英(在青光眼实验模型中保护视网膜神经节细胞免于死亡)(Hains和Waxman,2005),显示在神经退化模型范围中的神经保护功效。由于供氧失败危及醣酵解和氧化磷酸化,缺血性损害最终导致电失效(神经信号)和泵失效(细胞膜电势的复原)。这些失效(电和离子泵活性)与下降的ATP的局部浓度有关(Astrup等人1981)。因而化合物的以下效果得以显现,在严重的新陈代谢损害后维持在大鼠海马区的0.4mm切片中ATP的浓度(具有新陈代谢抑制因子的培养,碘乙酸盐)。
实验步骤:
制备大鼠前脑突触体和匀浆:
实验使用重175-250g的雄性Wistar大鼠的前脑(无小脑/髓质的整个大脑)来进行。进行所有努力以减少使用的动物的数量,所有实验根据UK Animals(Scientific Procedures)Act,1986和the European Community Council Directive of 24November1986(86/609/EEC)进行。以下通过击昏和断头处死动物,将前脑(无小脑/髓质的整个大脑)快速地切开并转移至含有冰冷的0.25M蔗糖的称量管中。
突触体(包含突触体的重和轻的线粒体部分)通过转移前脑(已知净重)至玻璃陶工器皿中和使用特氟隆研钵的均匀化来制备,所述器皿中已添加9体积冰冷的0.25M蔗糖,所述均匀化通过设定为900rpm的Braun Potter S马达驱动的匀质器8“上和下冲程”来进行。将所得匀浆在1036x g下在4℃下离心10min,收集上清液。如上,将剩余小球在新鲜冰冷的0.25M蔗糖中再悬浮,并重复离心步骤。将上清液部分汇集并在40,000x g(平均)在4℃下离心15min,将所得小球以每毫升合适检测缓冲液20-25mg湿重的浓度在合适的检测缓冲液中再悬浮。
匀浆通过转移已知重量的前脑至含有9体积冰冷的50mMpH 7.4的HEPES缓冲液的冷却的管中来制备。将混合物在4℃下通过设定在最大速度下的Ultra-TurraxTM匀质器的3x5sec脉冲均匀化。将所得匀浆在40,000x g(平均)下在4℃下离心15min,丢弃上清液。将所得小球再悬浮在9体积新鲜冰冷的pH 7.4的缓冲液中(如上),重复离心步骤,将所得小球以每毫升检测缓冲液20-25mg湿重的浓度在[3H]BTX-B结合缓冲液中再悬浮。

所有步骤在4℃(或在冰上)进行。将新切割的大鼠肝脏切入0.25M的冰冷蔗糖中,随后在包含15mM二硫苏糖醇的50mM pH6.0的磷酸盐缓冲液(10ml/g组织)中均匀化(U-turrax)。将所得匀浆在47,500x g下离心20min,在使用前将上清液(通过棉絮过滤以除去脂肪块)贮存在-80℃下(Rothenberg等人)。
[3H]甲氨蝶呤结合至大鼠肝脏匀浆上清液部分的抑制基本上如Arons等人,1975所述进行。简要地,将化合物在室温下,在巯基乙醇(60mM)存在下,在最终体积410μL的50mM pH 6.0的磷酸盐缓冲液中,用NADPH(480μM)、肝脏上清液(DHFR酶)和[3H]甲氨蝶呤(50nM)温育15分钟。结合反应通过添加50μl木炭悬浮液(由在50mM pH 6.0的磷酸盐缓冲液中悬浮的以重量比100∶4∶1存在的木炭、牛血清白蛋白和葡聚糖组成)而停止。将样品旋转,使其放置2分钟,将木炭通过在全速下微量离心5min来沉淀。将清晰的上清液的等分试样转移至含有用于使用液体闪烁光谱的放射性测量的液态闪烁体的计数瓶中。
将[3H]甲氨蝶呤的特定结合确定为在200μM“冷”甲氨蝶呤存在和不存在下结合的差异。百分抑制值通过与此值的比较来计算。

以及C=IC50(即为抑制50%特定结合需要的浓度)
海马切片检测:
以下通过击昏和断头处死动物,将前脑(无小脑/髓质的整个大脑)快速地切开并转移至含有冰冷的预充气(pre-gassed)的人造脑脊液(aCSF)的容器中。将海马快速地切割,使用Mcllwain组织切片机制备0.4mm切片。将切片任意地分布在50ml含有25-30ml冰冷的预放气的aCSF的锥形烧瓶中。当将介质通过真空吸出除去时,将烧瓶用95%O2/5%CO2在连续充气(continuedgassing)下在30℃下温育30分钟。添加新制的aCSF,将切片如前所述进一步温育30分钟。介质再次通过真空吸出除去,并用25ml预先升温(30℃)的无Ca2+的aCSF代替。在连续充气下再温育10min之后,通过立即转移至含有0.4ml冰冷的0.5M三氯乙酸(TCA)的各微量离心管中除去2-3片(使用Eppendorf移液管在100μl体积中)用于测量ATP和蛋白质。将碘乙酸盐(25μl 0.4M的溶液)添加至烧瓶中,并停止充气。正好11min后,将3-4片切片除去,并转移至如前所述的微量离心管中。
测量ATP和蛋白质:
通过超声将单个切片破坏,并将所得匀浆在10000x g下在4℃下离心5min。将上清液倒入新管中,任何剩余的上清液通过真空吸出除去。将小球通过超声再悬浮在0.5ml 0.1M KOH中,所得悬浮液伴随缓慢的搅拌在37℃温育30分钟。
通过与荧光素酶试剂(购自Perkin Elmer的ATPLite)混合并测量随后在96-孔板计数器中的发光,测量在6μl上清液中的ATP的浓度。
蛋白质浓度用牛血清白蛋白作为参考标准使用BCATM蛋白质检测(穿刺)来测量。
ATP浓度表示为nmoles/mg蛋白质,和通过与1μM TTX的效果直接比较计算的神经保护指标(%保护)。
hERG:
进行检测以测量在10μM下化合物的效果。进行假定结合斜率为1,对于具有10%和90%之间的抑制值的化合物,将IC50值外推。
