ⅱ.最好代表离去基团或OH,
b)使式Ⅳ化合物与式Ⅴ化合物反应,
式Ⅳ中A、R1、R2和R3的定义同上,
式Ⅴ中R4、R5、R6、R7和R8定义同上,R代表酯化了的基团,
ⅰ.在式Ⅰ化合物中,如果需要,可以将任意存在的-S-基团氧化为-SO-或-SO2-基团,
ⅱ.在式Ⅰ化合物中,如果需要,可以将任意存在的-SO-基团氧化为-SO2-基团,
ⅲ.如果需要,可以将R3代表氢的式Ⅰ化合物酰化、烷基化或芳烷基化,
ⅳ.如果需要,可以将R3不代表氢的式Ⅰ化合物水解,
ⅴ.如果需要,可以将式Ⅰ化合物转变成其生理上适用的盐,
上面ⅰ~ⅳ中二项或二项以上也可以按与上述不同的顺序进行。
M+代表阳离子,例如碱金属离子或碱土金属离子,铵离子或烷基铵离子,尤其是钠离子或钾离子。
如果按照优先选用的方法(a),使式Ⅱ化合物与式Ⅲ化合物反应,那么X1和X2代表可以亲核除去的离去基团,例如Cl、Br、I、-O-SO2-CH3、-O-SO2-CF3或-O-SO2-(C6H4-对CH3)。
式Ⅱ化合物与式Ⅲ化合物或其盐的反应在惰性溶剂(例如水、二氯甲烷、甲醇、乙醇、丙酮、乙酸乙酯、甲苯、四氢呋喃、乙腈、二甲基甲酰胺、二甲亚砜或上述溶剂的混合物)中,在无机或有机碱(例如氢氧化钠或氢氧化钾、碳酸钠或碳酸钾、醇钠或醇钾、氢化钠或氢化钾或氨化钠或
氨化钾、氨水、三乙胺、三丁胺或吡啶)存在下,于-20℃~+150℃,最好在0℃~80℃,可以容易地进行。
式Ⅱ化合物是已知化合物(例如,参见Gronowitz,The Chemistry of Heterocyclic Compounds”,Band44,“Thiophene and its Derivatives”,Parts 1~3,New York1985~6),或者可以按类似已知方法的方法制备,例如使上面定义的适当取代的2,3-、3,4-或4,5-二氨基噻吩(式Ⅳ)与合适的含硫化合物(例如二硫化碳)进行闭环反应制备(例如DE-A-313,2167)。
所需的2,3-、3,4-或4,5-二氨基噻吩可以按文献方法制备,或者可以按类似已知方法的方法制备。例如,可以通过还原适当取代的氨基硝基噻吩制得。
方法(b)应用的酯(式Ⅴ)中,R代表酯化了的基团,最好是(C1~C6)-烷基或苄基。
按照方法(b),式Ⅳ化合物与式Ⅴ化合物的反应,可以按照同Preston等在Benzimidazoles and Congeneric Tricyclic Compounds,Part 1,New York,P.10-3中所述类似的方法进行。
因此,如果R3代表氢,那么可以将制得的式Ⅰ化合物转变成生理上适用的盐。
应用合适的氧化剂,可以将T=-S-的式Ⅰ化合物进一步转变成T=-SO-或-SO2-的化合物。同样,也可以使取代基R1、R2和R7中的-S-基团氧化。
上述反应可以在合适的惰性溶剂(例如二氯甲烷、氯仿、四氯化碳、1,2-二氯乙烷、甲苯、乙酸乙酯、乙酸、三氟乙酸、水、甲醇、乙醇或它们的混合液中,于20℃~+150℃,最好在-10℃~+40℃进行。
合适的氧化剂有例如过氧化氢、过酸或过酸酯(例如过乙酸、三氟过
乙酸、单过氧邻苯二甲酸、间氯过苯甲酸及其酯)、臭氧、四氧化二氮、碘苯、N-氯琥珀酰亚胺、1-氯苯并三唑、次氯酸钠、过氧二硫酸钾、次氯酸叔丁酯、过碘酸或高锰酸四丁基铵、偏过碘酸钠、二氧化硒或二氧化锰、硝酸铈铵、铬酸、氯、溴、二氮杂双环-[2.2.2]辛烷-溴复合物、二溴化二噁烷、过溴吡啶鎓、硫酰氯、2-芳磺酰基-3-芳氧基氮丙啶、四异丙醇钛/叔丁基过氧化氢(任意地加入(D)-或(L)-酒石酸二烷基酯以及一定量的水)。
同样,分离出的任意固定氧化酶或微生物也可以作为氧化剂使用。
应用等摩尔量的氧化剂,如果合适,在氧化成T=-SO-中可以应用略超过5~10摩尔%的氧化剂,或者当氧化成T=-SO-时,甚至需要大的过量和/或需要较高的反应温度。
本发明也涉及式Ⅲ的新中间体。它们可以应用本领域技术人员熟知的方法,例如按“The Chemistry of Heterocyclit Compounds-Pyridine and its derivatives”,Parts 2 and 3,E.Klingsberg Ed.Interscience publishers,1962所述方法制备。
除了从X2代表羟基的式Ⅲ化合物合成X2代表离去基团的式Ⅲ化合物以外,还可以合成X2代表氯或溴的式Ⅲ化合物,例如用N-溴琥珀酰亚胺、三氯异氰脲酸使相应的2-甲基吡啶囟化[Chem,Ber.120,649~651(1987)],或者用其他的N-囟代酰胺(如N-氯代邻苯二甲酰亚胺)。
下面叙述几个制备X2代表羟基的式Ⅲ化合物的方法,但本发明不限于这几个实例。通过一般的方法,可以将它们转变成X2代表离去基团的式Ⅲ化合物。
从式Ⅵ硝基化合物或式Ⅶ含氯化合物,可以得到X2代表羟基、R6和R8相同或不相同且可以代表氢或甲基、R7代表单取代或多取代(C6~C12)-芳氧基或(C7~C11)-芳烷氧基的式Ⅲ化合物。
在惰性溶剂(例如四氢呋喃、二噁烷、乙腈、丙酮、甲基乙基酮、二甲亚砜、二甲基甲酰胺、二甲基乙酰胺、六甲基磷三酰胺或1,3-二甲基-3,4,5,6-四氢-2(1H)-嘧啶酮)中,于有机或无机碱(例如氢氧化钠、碳酸氢钠、碳酸钠、氢化钠或丙醇钠、碳酸锂、氢氧化钾、碳酸钾、氢化钾、碳酸氢钾或叔丁醇钾)存在下,在0℃~溶剂沸点之间温度,使式Ⅵ化合物或式Ⅶ化合物与式RH的醇反应。
与从式Ⅵ化合物制备式Ⅲ化合物相比,从式Ⅶ化合物制备式Ⅲ化合物是有利的,式Ⅶ化合物可以由式Ⅵ化合物经氯化剂(例如乙酰氯、亚硫酰氯和三氯氧化磷)作用制得。
也可以应用类似于Ⅶ的4-氟-2-甲基吡啶[J.Prakt.Chem.9,164~172(1959)]和4-氟-2-甲基吡啶-N-氧化物。
作醇使用的例如有4-氟-、4-氯-、4-三氟甲基-、2,4-二氟-、3,5-二氟-、3,5-二氯-、3,5-双-三氟甲基-和五氟苄基醇以及4-氟-、
4-氟-、3-三氟甲基-、2,4-二氟苯酚和四氟苯酚,但本发明不受这些实例的限制。
得到的式Ⅷ化合物与三氟乙酸酐在0℃反应,或者与乙酸酐,如果需要,在酸(例如冰醋酸)存在下,于80℃~120℃反应,得到乙酸酯(式Ⅸ)。
应用碱金属氢氧化物或碳酸盐,在甲醇、乙醇、水或类似的溶剂中,使式Ⅸ化合物进行碱水解,得到X2代表羟基的式Ⅲ化合物。
X2代表羟基、R6代表烷氧基、R8代表氢的式Ⅲ化合物可以按以下过程制备。
例如,2-甲基-3-羟基-7-吡喃酮X与囟化物RaX在氧化银存在下反应,或者与三氟甲磺酸氟代烷基酯反应,得3-烷氧基吡喃-4-酮,再与氨水反应,得2-甲基-3-烷氧基-4-吡喃酮(式Ⅺ)[J.Org.Chem.,29,776(1964)]。
应用囟化剂,例如POCl3,可以将式Ⅺ化合物转变成2-甲基-3-烷氧基-4-氯吡啶;应用醇RH,在碱存在下,可以由2-甲基-3-烷氧基-4-氯吡啶得到4-烷氧基衍生物。
为了得到式ⅩⅣ化合物,使类似物N-氧化物ⅩⅢ与醇化物反应是有利的。
所用取代的苄醇与酚前面已经提到过。
在氧化银存在下,可以由式Ⅺ化合物直接得到式ⅩⅤ化合物。
本发明还涉及以类似的方法,应用异构体5-羟基-2-甲基-4-吡喃酮(式ⅩⅦ)而不是应用2-甲基-3-羟基-7-吡喃酮(式Ⅹ)制备式Ⅲ化合物,5-羟基-2-甲基-4-吡喃酮(式ⅩⅦ)可以从曲酸ⅩⅥ制得(J.Chem.Soc.1956,2558)。
在EP-A-166,287和EP-A-208,452中,还叙述了制备3,4-二烷氧基-2-甲基吡啶和4,5-二烷氧基-2-甲基吡啶的方法。
新的式Ⅰ化合物及其盐具有重要的药理学性质。
它们明显地抑制胃酸分泌,此外,它们还具有极好的胃、肠保护作用。
“胃肠保护作用”是指可以预防和治疗胃肠病症,尤其是胃肠炎症或损伤(例如胃溃疡、十二指肠溃疡、胃炎或由于胃酸或多或药物所致的胃刺激),胃肠炎症和损伤可以由微生物、细菌毒素、药物(如抗炎药或抗风湿剂)、化学品(如乙醇)、胃酸或受力情况所引起。
根据取代的噻吩并咪唑(式Ⅰ)及其药理学上适用的盐的极好的特性,它们非常适用于作为人用药物和兽用药物,它们尤其可以用于治疗和预防胃和肠的病症以及由于胃酸过量分泌所引起的病症。
已经发现,在体外本发明式Ⅰ化合物与酸(例如与乙酸钠/缓冲剂,pH值约为4~5.5)形成的化合物,明显地抑制结肠H+/K+三磷酸腺甙酶(参见Gustin和Goodman,J.Biol.Chem.256,[1981]10651~10656)。在体内,使式Ⅰ化合物通过胃肠道,也可以生成上述
转化产物。转化产物生成的情况依赖于取代方式和pH值。
结肠H+/K+三磷酸腺甙酶对肠粘膜中电解质平衡有决定性的影响。因此,结肠H+/K+三磷酸腺甙酶抑制剂(如上述化合物)可以干预上述平衡,并可用于治疗电解质平衡紊乱的病症。
因此,本发明还涉及式Ⅰ化合物或其酸转化产物在治疗腹泻疾病中的应用。这样病症的例子有胃炎(如霍乱、副伤寒、旅行腹泻或其他形式的分泌腹泻),但是还包括溃疡性的结肠炎、克罗恩(Crohn)氏疾病和局限性回肠炎。
此外,本发明还涉及式Ⅰ化合物与酸反应生成的转化产物。
因此,本发明还涉及用于治疗和预防上述病症的式Ⅰ化合物。
同样,本发明还包括用于治疗和预防上述病症的药物制剂中本发明化合物的应用。
此外,本发明还涉及含有1个或1个以上式Ⅰ化合物和/或它们药学上适用的盐的药剂,以及包含式Ⅰ化合物和环糊精,特别是β-环糊精的药剂。
药剂可以按照本身已知的和本领域专业人员熟知的方法制得。本发明的药理学上有活性的化合物(即有效化合物)或者如上述作为药物应用,或者最好与合适的药用辅助剂并用制成片剂、糖衣丸剂、胶囊剂、栓剂、乳剂、混悬剂或溶液剂,其中有效成分含量最好为0.1~96%。
所需药物剂适用的辅助剂,本领域专业人员是熟悉的。除了溶剂之外,还须应用胶凝剂、栓剂基质、片剂辅助剂以及其他有效化合物赋形剂、抗氧化剂、分散剂、乳化剂、消泡剂、矫味剂、防腐剂、助溶剂或着色剂。
有效化合物可以口服或非经胃肠道服用,最好是口服。
为了获得预期效果,人用药中有效化合物的口服剂量,一般说来按体重计算,每天约0.01~20mg/kg,如果合适,可以分成几个(最好1~4
个)单独的剂量。作为规则,对于非经胃肠道给药,可以应用类似的或者较低的剂量(尤其是用有效化合物静脉给药)。任何熟悉本领域的人员根据其专门的知识,可以容易地确定各个病例所需服用的有效化合物的合适剂量和型式。
如果应用本发明化合物和/或它们的盐治疗上述病症,那么药用制剂还可以含有一种或一种以上药学上有效的其他药物成分,例如抗菌药物[如沃夫洛克赛齐恩(ofloxazine)]、抗酸剂(如氢氧化铝、铝酸镁、胃溃宁、铋盐)、安定药(例如苯并二氮*类,如安定)、解痉剂(如苯哌乙胺酯、胺苯戊酯)、抗胆碱能剂[如哌仑西平、特来折匹恩(telezapine)、羟苯环嘧、苯胺硫酯]、局部麻醉剂(如丁卡因、普鲁卡因),以及可任选添加的促胃液素拮抗剂、酶、维生素或氨基酸。
为得到口服剂型,将有效化合物与制剂中常用的添加剂(例如赋形剂、稳定剂或惰性稀释剂)混合,以常用的方法制成合适的服用剂型,例如片剂、糖衣丸剂、硬明胶胶囊剂、水混悬剂、醇混悬剂或油混悬剂,或水溶液剂、醇溶液剂或油溶液剂。阿拉伯树胶、氧化镁、碳酸镁、乳糖、葡萄糖或淀粉,特别是玉米淀粉可以用作为惰性赋形剂。在该情况下,可以制成干颗粒或湿颗粒。油状的赋形剂或溶剂有植物油和动物油,例如向日葵油或鳕鱼肝油。
为进行皮下注射或静脉注射给药,将有效化合物或它们的生理上适用的盐制成溶液剂、混悬剂或乳剂,如果需要,可以应用制剂中常用的物质,例如助溶剂、乳化剂或辅助剂。适用于本发明新的有效化合物及其相应生理上适用的盐的溶剂有例如水、生理盐水溶液或醇(例如乙醇、丙醇或甘油),此外还有糖溶液(如葡萄糖或甘露糖醇溶液)以及上述各种溶剂的混合液。
