表2
本发明的化合物经药理试验确证了其对酶FAAH(脂肪酸酰胺水解酶)的抑制作用。
试验方案1:抑制活性通过放射酶试验证明,该试验基于测定花生四烯酸乙醇胺(anandamide)[乙醇胺1-3H]经FAAH水解的产物(Life Sciences(1995),56,1999-2005和Journal of Biochemical and Biophysical Methods(2004),60(2),171-177)。因此,取小鼠大脑(去掉小脑)并在-80℃储存。使用仪在反应缓冲液(10mM Tris-HCl,pH=8,150mM NaCl和1mM乙二胺四乙酸(EDTA))中通过将组织匀浆来临时制备膜匀浆液。酶反应在96孔多屏过滤板(Multiscreen filtration plates)中进行,终体积为70μL。经无脂肪酸的牛血清白蛋白(BSA,1mg/ml)补充的反应缓冲液用于酶反应以及该化合物和花生四烯酸乙醇胺[乙醇胺1-3H]的稀释。连续向孔中加入含BSA的反应缓冲液(43μL/孔)、以不同浓度稀释的测试化合物(7μL/孔,含1%DMSO)和膜制品(10μL/孔,即每次试验200μg的组织)。该化合物在25℃与酶预培养20分钟后,通过加入用冷的花生四烯酸乙醇胺稀释的花生四烯酸乙醇胺[乙醇胺1-3H](15-20Ci/mmol的具体活性)(10μL/孔,最终浓度10μM,每次试验0.01μCi)启动反应。在25℃培养20分钟后,通过加入在1.5M NaCl和0.5MHCl缓冲液中制备的5M活性炭溶液(50μl/孔)终止该酶反应。将该混合物搅拌10分钟,然后通过真空抽滤回收含乙醇胺[1-3H]的水相,并通过液体闪烁(liquid scintillation)对其进行计数。
试验方案2:抑制活性通过酶试验中的荧光技术证明,该技术基于测定花生四烯酰基(arachidonoyl)7-氨基-4-甲基香豆酰胺(AAMC)经FAAH水解的荧光产物(Analytical Biochemistry(2005),343:143-151,J.of BiomolecularScreening(2006),11(5):519-527和J.of Neurosciences Methods(2007),161:47-54)。因此,取小鼠大脑(去掉小脑)并在-80℃储存。通过使用仪在反应缓冲液(10mM Tris-HCl,pH=8,150mM NaCl和1mM乙二胺四乙酸(EDTA))中将组织匀浆,临时制备脑组织匀浆液。该酶反应在黑色聚苯乙烯384孔板中进行,终体积为50μL。经无脂肪酸的牛血清白蛋白(BSA,1mg/ml)补充的反应缓冲液用于酶反应、该化合物的稀释和AAMC的稀释。连续向孔中加入含BSA的反应缓冲液(25μL/孔)、以不同浓度稀释的测试化合物(5μL/孔,含1%DMSO)和膜制品(10μL/孔,即每次试验200μg的组织)。在25℃与酶预培养20分钟后,该反应通过每孔加入10μL底物(AAMC,最终浓度为10μM)启动。在37℃培养40分钟后,通过荧光计数(Envision板读数器)测量产生的氨基甲基香豆素(AMC)。
在试验方案1的条件下,本发明的最具活性的化合物具有0.001μM至1μM的IC50值(抑制50%的FAAH的对照酶活性的浓度)。例如3、7、12、23、28和34号化合物分别具有3.5nM、89nM、19nM、34nM、12nM和3.2nM的IC50值。
在试验方案2的条件下,本发明的最具活性的化合物具有0.001μM至1μM的IC50值(抑制50%的FAAH的对照酶活性的浓度)。例如44和45号化合物分别具有7.4nM和0.47nM的IC50值。
由此表明本发明的化合物对酶FAAH具有抑制活性。
在止痛试验中评价了本发明的化合物的体内活性。
因此,将PBQ(苯基苯醌,以2mg/kg溶于含5%乙醇的0.9%氯化钠溶液中)腹膜内(i.p.)给药于体重为25至30g的雄性OF1小鼠导致腹部强直(stretching),注射后5至15分钟的时间内平均扭转(torsion)或收缩(contraction)30次。在给药PBQ 60分钟或120分钟之前,将该测试化合物以0.5%混悬于吐温80中,通过口服(p.o.)或腹膜内(i.p.)给药。在这些条件下,在1和30mg/kg之间的剂量范围,本发明最有效的化合物使PBQ诱导的强直数量减少了35%至80%。
例如,表1的化合物24和35(在30mg/kg的口服剂量,在120分钟)减少了50%的PBQ诱导的强直次数,
酶FAAH(Chemistry and Physics of Lipids,(2000),108,107-121)催化多种脂肪酸酰胺和酯的内源性衍生物(例如N-花生四烯酰基乙醇胺(花生四烯酸乙醇胺)、N-棕榈酰乙醇胺、N-油酰乙醇胺、油酰胺或2-花生四烯酰基甘油)的水解。这些衍生物尤其通过与大麻素和辣椒素受体相互作用产生不同的药理学活性。
