Description
本发明涉及具有类视网膜活性的新化合物。更具体是涉及含有一个为取代的乙炔基苯基部分和第二个为四氢喹啉基,二氢苯并噻喃基或苯并二氢吡喃基部分的化合物。可以预料到这些化合物的氧化产物,特别是二氢苯并噻喃基的氧化物将具有类似其母体化合物的活性。
1985年1月9日公开的欧洲专利申请0133795中,揭示了通式4-(2-(4,4-二甲基-6-X)-2-丙烯基)苯甲酸的羧酸衍生物具有抑制软骨变形作用,通式中X表示四氢喹啉基,苯并二氢吡喃基或二氢苯并噻喃基。M.I.Dawson等人在医学化学杂志,第27卷,1516页的文章中揭示了类似于本发明的化合物,他们用炔属基团代替甲基取代的反式双键(Dawson中所显示的)。另外在1986年4月2日公开的欧洲专利申请176034A中,也揭示了含有乙炔基苯甲酸的四氢萘化合物。
本发明是关于下式Ⅰ化合物或其药物上可接受的盐
式中X是S,O或NR1其中R1是氢或低级烷基;n是0-5;R是H或低级烷基;A是H,-COOH或其药物上可接受的盐,酯或酰胺,-CH2OH或其醚或酯的衍生物,或-CHO或其缩醛衍生物,或-COR2或其缩酮衍生物(其中R2是-(CH2)mCH3,m是0-4)。
本发明第二方面是关于使用式Ⅰ化合物治疗皮肤病,例如痤疮,达里埃氏病,牛皮癣,鳞癣,湿疹,特应性皮炎和上皮癌。这些化合物还可以用于治疗关节炎病症和其它免疫性疾病(例如红斑狼疮),促进伤口愈合,干眼综合症以及消除阳光损伤皮肤。
本发明还涉及一种药物配方,该配方包括式Ⅰ化合物和用于组合的药物上可接受的赋形剂。
在另一方面本发明是关于制备式Ⅰ化合物的方法,其包括在有Pd(PQ3)4(Q是苯基)或类似配合物存在下,式Ⅱ化合物同式Ⅲ化合物反应得到相应的式Ⅰ化合物,
式中X1是卤素,较好为I;R是氢或低级烷基,n定义同上;A是H或保护的酸,醇,醛或酮;
脱除式Ⅰ的保护的酸,醇,醛或酮,
或对下式化合物(n是0-4)进行反应得到式Ⅰ的酸;或
式Ⅰ的酸转化成酸加成盐;或式Ⅰ的酸转化成酯;或
式Ⅰ的酸转化成酰胺;或还原式Ⅰ的酸得醇或醛;或
式Ⅰ的醇转化成醚或酯;或
氧化式Ⅰ的醇得醛或酮;或
式Ⅰ的醛转化成缩醛;或
式Ⅰ的酮转化成缩酮。
本文所用述语“酯”是指和包括有机化学经典使用述语定义内的任何化合物。当A为-COOH时,该述语包括处理含醇官能团所衍生得到的产物。如酯是由A为-CH2OH的化合物衍生得到的,那么述语“酯”包括式-CH2OOCR化合物,其中R是任何取代的或未取代的脂肪族,芳族或脂族-芳香族基团。
较理想的酯是由10或10多个碳原子的饱和脂肪醇或酸,或5到10个碳原子的环状或饱和脂肪环醇和酸衍生得到的酯。最好是由低级烷基酸同醇衍生得到的化合物。在本文,无论何处凡所用的低级烷基都是指1-6个碳原子,但苯基或低级烷基苯基酯也是较理想的。
酰胺具有有机化学经典的定义。在本文情况里,酰胺包括未取代酰胺和全部脂肪和芳香族单和二取代酰胺。较好的酰胺是由低级烷基取代的胺或低级烷基脂肪环基或芳香基(如苯基)取代的胺所衍生得到的单和二取代酰胺。那些由低级烷基胺得到的酰胺最好。由苯基或低级烷基苯基胺衍生得到的单和二取代酰胺也较理想,这对未取代的酰胺也是如此。
缩醛和缩酮包括式-CK的基团,其中K是(-OR)2,这里R为低级烷基。K也可为-OR1O-,其中R1是2-5个碳原子的直链或支链的亚烷基。
凡具有能形成如酸或胺官能度的盐的本发明化合物,都能制成其药物上可接受的盐。药物上可接受的盐是指能保留母体化合物活性,并且对给药者或经给药后的用者都不引起有害或不利影响的任何盐类。
酸的药物上可接受的盐可以由有机或无机硷衍生得到。这类盐可以是单或多价离子,无机离子具体较佳的是钠,钾,钙和镁。有机胺盐可由胺制得,具体的铵盐如单,二和三烷基胺或乙醇胺。盐也可由咖啡碱,三甲醇氨基甲烷和类似分子制得。当是由胺得到酸加成盐时,可以使用任何无机或有机酸。较好的盐为盐酸盐,硫酸盐,磷酸盐,以及含2-6个碳原子,可单或二酸式盐的有机酸的盐。季铵化合物可由烷基化试剂如甲基碘等制得。
本发明较好的化合物为其中(CH2)n-A基团是在苯环上乙炔基的对位;n是0,1或2;A是-COOH或其硷金属盐或有机胺盐或低级烷基酯,或-CH2OH和其低级烷基酯和醚。最理想的化合物为:
4-〔4,4-二甲基二氢苯并噻喃-6-基)苯甲酸;
4-〔4,4-二甲基二氢苯并噻喃-6-基乙炔基〕苯甲酸乙酯;
4-〔4,4-二甲基苯并二氢吡喃-6-基乙炔基〕苯甲酸乙酯;
4-〔4,4-二甲基苯并二氢吡喃-6-基乙炔基〕苯甲酸。
根据需治疗的病情,具体治疗的部位,用药量和其它应考虑的因素,本发明化合物可以按全身或局部进行给药。
在治疗皮肤病中,虽然在某些病例如治疗严重的囊性痤疮也可使用口服给药,但通常都采用局部给药。可以使用任何普通的局部配方如溶液、混悬液、凝胶、软膏、油膏。这种局部给药的配方在药物配方技术中已有具体的描述,如Easton,Pennsylvania,Mack出版公司第17版,Remington's Pharmacentical Science。对于局部使用,这些化合物还可以以粉剂或喷雾形式,尤其以气溶胶形式给药。
如果是用于全身给药,可以制成粉剂,丸剂,片剂等,或制成糖浆或剂用于口服。而在用于静脉内或腹膜内给药时,本化合物可制成溶液或悬浮液形式进行注射给药。在某些情况下,也可把本化合物制成栓剂形式,或在用于植入皮内的或肌肉内注射时,可制成持续释放的配方形式。
在这种局部配方中加入其他的药剂可起到治疗如皮肤干燥,防止光照等第二个目的,同样可加入其它的药剂,可用于治疗皮肤病,防此感染,减缓疼痛,炎症等。
凡适于类视网膜酸化合物治疗的皮肤病或任何其它已知或发现的病症,治疗有效量的一个或多个本发明化合物都能用于治疗。治疗浓度是能有效减缓具体病情或阻缓病情发展的扩展。在某些情况下,能以预防形式使用本化合物,起到防止具体病情的引发。根据具体病情的不同,所给的治疗浓度是不同的,在某些情况下,根据需治疗情况的严重程度和病者对治疗的反应来取定用药浓度。因此,最好是在具体用药的时候和地方,通过常规实验测定所用治疗浓度。然而,我们可以预计到在治疗如痤疮或其它皮肤病时,有效治疗浓度的配方是通常含0.001至5重量百分比。较好是约0.01至1%。如果是全身给药,那每天用量为0.01至100mg/kg体重,但在大多数情况下,0.1至10mg/kg的治疗结果较好。
这些化合物的类视网膜酸活性是用常规测定视网膜酸活性的方法加以证明,这包括这些化合物在鸟尿酸脱酸酶上的作用。最初是有verma & Boutwell,(癌研究,37卷,2196-2201页,1977年)研究视网膜酸与减少细胞增生之间的关系。这篇文献揭示了,在聚胺生物合成前,鸟尿酸脱酸酶(ODC)活性已增加了。另外还确立了这样的理论,即聚胺合成的增加同细胞增生有关或者有联系。因此,如果能抑制ODC活性的话,也就能调节细胞高增生。现在虽然还不知道引起ODC活性增加的全部因素,但12-邻十四烷酰佛波醇-13-乙酸盐(TPA)能诱发ODC活性是已知。视网膜酸能抑制由TPA引起ODC活性的诱发。本发明化合物也具有抑制TPA诱发ODC的功用,这基本上按《癌研究》,1662-1670,1975,的方法来测定。
本发明化合物可用不同的化学合成方法进行制备。为了描述本发明,本文概述了一系列合成步骤,实际按照它们或其原则就能合成得式Ⅰ化合物。对化学合成的工作者来说,这里所列的条件显然是具体的实例,可以从其中推广到式Ⅰ表示的任何一个化合物。
其中X是-S-的式Ⅰ化合物可按照反应路线Ⅰ制备
反应路线Ⅰ
式中,R是氢或低级烷基,Q是苯基,n是0-5,A是H或保护的酸,醇,醛或酮。X可以是Br,Cl或I,但当n是0时,Br和I较好,并且n是1-5时,I为较好。
下面将描述反应路线Ⅰ中合成适用的一般反应条件。首先式Ⅰ的苯硫酚在一个极性溶剂如丙酮中,用约等摩尔量的强硷如硷金属氢氧化物最好是氢氧化钠回流处理,回流时间为1至4小时,较好为2.5小时。然后所得溶液用等摩尔量式2的1-溴-3-甲基-2-丁烯(Aldrich)于烷剂中处理。再继续回流2天后,在室温下搅拌24小时生成式3,然后用常规方法加以分离。
在隋性气氛和有磷酸存在下,用五氧化二磷处理进行闭环得式4。具体是硫化物首先溶于隋性溶剂如苯,甲苯等,然后用略为过量的五氧化二磷及浓磷酸处理。所得溶液在隋性气体如氩气或氮气中搅拌回流24,然后按常规损伤回收和纯化产物。
在有氯化铝存在下,二氢苯并噻喃经乙酰氯处理得到式5的酮。在隋性气氛和低温(-10至10℃)下。制备得氯化铝于极性隋性溶剂中的悬浮液,所说隋性气氛可以是氩气或氯气,较好为氩气。本步骤的反应通常是在如二氯甲烷的溶剂中进行,用滴液漏斗或类似装置把氯化铝悬浮液加到二氢苯并噻喃和乙酰氯中。并且使用相对于二氢苯并噻喃物料过量5%摩尔的乙酰氯和过量10%摩尔的氯化铝。反应是在10-50℃的温度下搅拌0.5-4小时。最好是在室温下搅拌约2小时。然后用水和/或冰骤冷反应物,萃取产物并分馏或其它一些合适方法纯化产物。
在隋性气氛和低温下,用二异丙基酰胺锂或类似的硷引进式6的乙炔基官能度。该反应是在醚类溶剂如二烷基醚或环醚中进行,如四氢呋喃,吡喃等。
具体地说,二异丙基酰胺锂是在现场制备的,即通过二异丙基酰胺在无水溶剂如四氢呋喃中混合,于隋性气氛下冷却至-70℃和-50℃之间来制备。在低温下,加入于适当溶剂中的等摩尔烷基锂化合物,混合适当的时间至生成二异丙基酰胺锂(LDA)。把式5的酮(至少过量10%摩尔)溶于反应溶剂中并冷却至LDA混合物的温度,然后加入到LDA混合物中。经简单混合后,用过量20%摩尔的氯磷酸二烷酯,最好是氯磷酸二乙酯处理溶液。然后反应液渐渐热至室温,并加入到第二部份的二异丙基酰胺锂溶液中,该二异丙基酰胺锂也是在现场,于隋性气氛(较好氩气)和低温(例如-78℃)下使用无水溶剂制得的。再将所得的反应混合物温热至室温,并搅拌维持一段时间,较好是10至20小时,最好约15小时。然后酸化溶液,用常规方法回收产物。
式7化合物的制备是在无水隔氧的条件下进行的。可以使用无水的醚类溶剂如二烷基醚或环醚如呋喃或吡喃,尤其是四氢呋喃作为溶剂。式6溶液的制备首先是在隋性气氛如氩气或氮气下,然后加入强硷如正丁基锂(约过量10%摩尔)。反应是介于-10℃至10℃的低温,较好在0℃下进行。短期搅拌反应混合30分钟至2小时,接着用溶于反应溶剂的10%摩尔过量的熔融氯化锌进行处理。在起始温度下再搅拌混合物1-3小时,然后升温至环境温度10-40分钟。
式Ⅰ化合物是通过用式8的囟代的苯基的化合物(其中A是饣虮;さ乃幔迹┗蛲┩?的ZnCl盐偶合制得。式8化合物,即保护的酸等是化工厂有售的或者可用公知方法加以制备的。如果起始原料是酸,在亚硫酰二氯存在下,把该酸在适当的醇溶液中回流酯化,经回流2-5小时后得到所期望的酯。用常规方法回收和纯化所得酯。醇,醛和酮类都可以用McOmie,Plenum Publishing Press,1973和《保护基团》,Ed.Geene,John Willey & Sons,1981所描述的那些已知方法被形成醚和酯,缩醛或缩酮来进行保护。
为了增加n数值,而这些化合物不是商业有售的,可在阿恩特一艾斯特条件下,连续处理卤代苯甲酸或苯基烷基酸。然后按前面所述的一般方式酯化这些酸类。另外,可由这些制得其相应的醇或醛,并且酸经酯化或形成缩醛,或经类似保护反应后,可用于下列的偶合反应。
为了制备式Ⅰ化合物,(通过偶合反应)式8首先溶于一种无水反应溶剂。使用的式8化合物量与式7的摩尔浓度相接近。把式8的溶液加入到温度为-10℃-10℃四-三苯基磷钯(约过量于反应物摩尔量的5-10%)的反应溶剂悬浮液中。短暂搅拌该混合物约15分钟,立即在这所制得的反应混合物中加入式7的预制备溶液,这是在室温下进行的。在室温下,搅拌该溶液约15至25小时。然后用酸骤冷反应物,用常规操作分离和纯化产物得到式Ⅰ化合物。
制备其中n为1-5的化合物的另外方法是使用上面提到的阿恩特-艾斯特方法对n=0和A是酸官能团的式Ⅰ化合物进行反应。
X为氧的式Ⅰ化合物可按反应路线Ⅱ进行制备
反应路线Ⅱ
其中如反应路线Ⅰ所定义,n是0-5,R是氢或低级烷基,A是H或一个保护的酸,醇,醛或酮,X1可以是Br,Cl或I,但n是0时,Br或I较好,而n为1-5时,则I为较佳者。
这些化合物制备如下。式11的磷酸盐由相应的氯磷酸二苯酯和3-甲基-3-丁烯-1-醇制得,这些起始由Aldrich提供或已知方法制得。较好是在隋性气氛下把式10的醇溶于约过量10%的吡啶或类似物中并冷至约-10至10℃。然后在隋性气氛下,将上面溶液滴加到约等摩尔量氯磷酸二苯酯于反应溶剂的溶液中,使用的氯磷酸二苯酯摩尔量约过量于使用醇化合物的2-5%。隋性气氛可以是氩,氮或其它惰性气体。将混合物加热回流1-5小时,较好约3小时来完成反应。然后按常规方法回收产物。
把由上面(式11)所得的二苯基磷酸酯与苯酚反应制得化合物12。例如,在氩气和冷却至-10-10℃的装有氯化锡的烧瓶中加进苯酚,在低温下,进行完全混合约15分钟至1小时,接着低温下加入磷酸盐,这些步骤都是在隋性气氛如氩气或氮气下进行。磷酸盐加入完毕后,在环境温度下搅拌混合物至24小时。然后用硷金属硷等的稀水溶液骤冷,用常规方法萃取回收产物。
其后,式12化合物依次用反应路线1已描述制备酮,炔属化合物和其ZnCl盐的同样方法偶合反应处理形成得到式Ⅰ化合物。
其中X是氮的化合物可按下列反应路线制备:
如同上面一样,这里n是0-5,A是H或一个保护的酸,醇,醛或酮。R2可以是氢或一个保护基团如-COCH3。X可以是Br,Cl或I。当n是0时,Br和I为较好,而n为1-5时,I为较好。
四氢喹啉部分(即X为氮)可部分按1985年9月1公开的欧洲专利申请0130795的方法进行制备。首先,将3-甲基丁烯酰氯与苯胺反应得到酰胺(式18),然后,在有溶剂存在下用氯化铝环化酰胺得到式19。用氢化铝锂或其它可接受的相似类型还原剂还原2-氧代-1,2,3,4-四氢喹啉,这最好在惰性溶剂如乙醚中进行。在极性溶剂如吡啶中,用乙酰氯酰化胺,接着有氯化铝存在下再酰化得到式21化合物。然后硷性水解式21化衔锏檬?2的仲胺。按反应路线Ⅰ中制备化合物6至7的方法处理式22化合物,分别得到式23和24化合物。按前述偶合式25化合物得式Ⅰ化合物。
衍生于式Ⅰ的酸和盐可容易地从相应的酯获得。用硷金属硷皂化可得到酸。例如,最好在隋性气氛和室温下,用约过量3摩尔的硷如氢氧化钾可以把式Ⅰ的酯溶于一个极性溶剂如醇中,搅拌溶液15-20小时,冷却,酸化和用常规方法回收水解物。
酰胺可采用已知的任何适当的酰化方法制备得到。制备这类化合物的一种方法是把酸转化成酰基氯,然后用氢氧化铵或适当的胺处理。例如,在室温下,醇硷溶液如醇KOH(约过量10%摩尔)处理酸约30分钟。除去溶剂,剩余物溶于有机溶剂如乙醚中,用二烷基甲酰胺处理,然后用过量10倍的草酰氯处理,这操作都在介于约-10℃-10℃的温和的低温下进行。然后低温搅拌所得溶液1至4小时,较好为2小时。把除去溶剂的剩余物溶于隋性有机溶剂如苯中,冷却至约0℃并用浓氢氧化铵处理。所得混合物低温搅拌1-4小时,常规方法回收产物。
醇类的制备可用亚硫酰二氯把相应的酸转化成酰基氯(J.March,“高等有机化学”,第2版,McGraw-Hill出版公司),然后用氢硼化钠还原酰氯(March,Ibid,Pg.1124)得到相应的醇,或者低温用氢化铝锂还原相应的酯。在威廉逊制醚反应条件下,用适当的烷基卤烷基化这些醇得到相应的醚(March,Ibid,Pg.357)。在有酸催化剂或二环己基碳二亚胺和二甲氨基吡啶存在下,通过这些醇同羧酸反应能制得这些醇的酯。
使用温和氧化剂如重铬酸吡啶鎓的二氯甲烷(Corey,E.J.,Schmidt,G.,Tet.Litt.,399,1979)或二甲亚砜和草酰氯的二氯甲烷(Omura,K.Swen,D.Tetrahedzon,1978,34,1651),由相应的伯醇制得醛。
按March,Ibid,p810所描述方法,由相应的醛或酮能制得缩醛和缩酮。
