Description
本发明涉及抗菌素化合物-非对映的5R,6S-6-(1R-羟乙基)-2-(顺式-1-氧-3-硫杂环戊烷基硫)-2-青霉烯-3-羧酸,即下式(Ⅰ)的2-(1S-氧-3R-硫杂环戊烷基硫)变体和下式(Ⅱ)的2-(1R-氧-3S-硫杂环戊烷硫基)变体,涉及药物上可接受的盐和其可体内水解的酯,涉及和用于制备所述非对映异构体的中间体和方法。
Hamanaka的美国专利4,619,924号和欧洲专利申请130,025号公开了作为有效抗菌物质的5R,6S-6-(1R-羟乙基)-2-(顺式-1-氧-3-硫杂环戊烷基硫)-2-青霉烯-3-羧酸,这是一类两种化合物的非对映混合物。虽然通过分析可检测,可迄今仍未获得具有给定结构的纯的非对映化合物。Volkmann等的欧洲专利申请(预定于1987年5月27日公开,编号为223,397)描述了从外消旋的顺式-3-(乙酰硫)硫杂环戊烷-1-氧化物制备所述非对映混合物的改进方法,该方法采用与目前所用的中间体不相类似的混合性非对映中间体。
就现有的旋光活性母体而言,Brow等人已在J.Am.Chem.Soc.,Vol.108,pp.2049~2054(1986)上报导了通过对2,3-二氢噻吩进行不对称的硼氢化反应,合成(S)-3-羟基硫杂环戊烷〔疏忽地描述为(R)异构体),但实际上其构型与下式(Ⅺ)的(R)-3-羟基硫杂环戊烷的构型相反〕。Jones等人在Can.J.Chem.,Vol.59,pp.1574~1579(1981)上介绍,对外消旋的3-羟基硫杂环戊烷的部分酶氧化,可回收含稍过量(R)异构体的3-羟基硫杂环戊烷。〔下式(ⅩⅢ)、其中R9=CH3的〕本发明的旋光母体(R)-(2-甲硫酰氧基乙基〕环氧乙烷和〔下式(Ⅹa)、其中R8=CH3的〕(S)-2-溴-1,4-二(甲磺酰氧基)丁烷均是已知的化合物,均可按Shibata等人在Heterocycles Vol.24,pp.1331~1346(1986)中介绍的方法制备,前者还可根据Boger等人在J.Org.Chem.,Vol.46,pp.1208~1210(1981)上介绍的方法制备。
我们发现了制备非对映青霉烯化合物的方法即绝对立体化学式为(Ⅰ)的5R,6S-6-(1R-羟乙基)-2-(1R-氧-3S-硫杂环戊烷基硫)-3-羧酸盐和绝对立体化学式的5R,6S-6-(1R-羟乙基)-2-(1R-氧-3S-硫杂环戊烷基硫)-3-羧酸盐。式Ⅰ和式Ⅱ分别为:
式中R为氢或为在生理条件下可水解酯基;并且当R为氢时,为该化合物的药物上可以接受的阳离子盐。
由于所有这些化合物及其若干中间体母体是单一均匀的化合物,因此与先前所报道的这些化合物的非对映混合物相比,可更好地控制该最终产品的质量,这是作为临床应用的重要因素。根据对经过分离的化合物(Ⅰ)和(Ⅱ)的体外研究,两者的抗菌活性几乎完全相同。然而,令人意想不到的是,当其呈新戊酰氧基甲酯形式时,与式(Ⅰ)异构体相比式(Ⅱ)的异构体更易口服吸收;不管将其作为钠盐非肠道施用,还是作为新戊酰氧基甲酯口服施用,由于代谢破坏程度下降,异构体(Ⅱ)尿回收的能力实际上两倍于异构体(Ⅰ)。鉴于上述原因,本发明的纯的非对映异构体优于先前的非对映混合物,而式(Ⅱ)异构体最佳。
所述的药物上可接受的阳离子盐包括(但不限于):钠盐、钾盐、钙盐、N,N′-二苄基乙二胺、N-甲基葡萄胺(葡甲胺)和二乙醇胺等盐。较佳的阳离子盐类为钾和钠的盐类。
在生理条件下可水解的酯通常称为“前药”。在青霉素领域中,这类酯是众所周知的,一般作为药物上可接受的盐。这类酯通常用来增进口服吸收,但总是极易在体内水解成母体酸。更理想的形成酯的基团是这样一些基团,其中R为:
(5-甲基-1,3-二氧杂环-2-酮-4-基)甲基,
1H-异苯并呋喃-3-酮-1-基,
γ-丁内酯-4-基,
-CHR1OCOR2,或
-CHR1OCOOR3,
式中R1为氢或甲基;R2为(C1-C6)烷基、(C1-C6)羧基烷基、羧基环己基或羧基苯基;R3为(C1-C6)烷基。最理想的基团是新戊酰氧基甲基和1-(乙氧羰基氧基)乙基。
本发明还涉及具有如下绝对立体化学式的中间体化合物或其盐(当R5为氢时),
式中R4是氢或普通的甲硅烷基羟基保护基,最好是叔丁二甲基甲硅烷基;R5是氢、-CH2-CX=CH2或-CH2-O-CO-C(CH3)3(条件是当R4为氢时,R5为-CH2-CX=CH2),X为氢或氯,最好是氯;
式中R6为所述的普通甲硅烷基保护基,R7为氢或
式中R8为(C1-C3)烷基、苯基或甲苯基,最好是甲苯基,n为0或1。
本发明进一步涉及:
(1)制备具有式(Ⅶa)绝对立体化学式的化合物的方法,
(a)在对反应呈惰性溶剂中,用碱金属硫化物,将具有绝对立体化学式(Ⅻ)的化合物进行常规的环化,以形成具有绝对立体化学式(Ⅸa)的化合物,
式(Ⅻ)中R8为(C1-C3)烷基、苯基或对甲苯基(最好是甲基);
(b)在对反应呈惰性溶剂中,将式(Ⅸa)化合物同大致为一当量的氧化剂反应,形成绝对立体化学式(Ⅸb)的化合物
(c)在对反应呈惰性溶剂中,将式(Ⅸb)化合物中的溴基与硫代乙酸碱金属进行常规的亲核置换反应,得到绝对立体化学式为(Ⅶb)的化合物:
(d)在对反应呈惰性溶剂中,通过CS2和碱金属(C1-C3)醇盐、最好是乙醇钠的作用,把式(Ⅶb)的化合物转化成式(Ⅶa)化合物;
(2)制备绝对立体化学式(Ⅷa)化合物的方法,
(a)在对反应呈惰性溶剂中,通过碱金属硫化物的作用,将具有绝对立体化学式(ⅩⅢ)的环氧化物转化成具有绝对立体化学式(Ⅺ)的化合物,
式中R9为(C1-C3)烷基、苯基或对甲苯基,最好是甲基;
(b)在对反应呈惰性溶剂中,对式(Ⅺ)化合物进行常规的磺酰化反应,形成具有绝对立体化学式(Ⅹa)的化合物
式中R8为(C1-C3)烷基、苯基或甲苯基,最好是甲苯基;
(c)在对反应惰性溶剂中,对式(Ⅹa)化合物进行常规的氧化反应,以形成具有绝对立体化学式(Ⅹb)的化合物,
(d)在对反应惰性溶剂中,用硫代乙酸碱金属盐将式(Ⅹb)化合物中的R8-SO2-O进行常规的亲核置换,以形成式(Ⅷb)化合物
(e)于对反应惰性溶剂中,经CS2和碱金属醇盐(最好是乙醇钠)的作用,按常规方法将式(Ⅷb)化合物转化成所述的式(Ⅷa)化合物;
(3)制备绝对立体化学式(ⅩⅢ)化合物的改进方法,
式中R9为(C1-C3)烷基、苯基或对甲苯基,最好是甲基,该方法包括如下步骤:
(a)在对反应惰性溶剂中,将绝对立体化学式(ⅩⅣ)的化合物
同Cs2CO3反应,形成绝对立体化学式(ⅩⅤ)化合物,
这一步的化学计量收率超过90%;
(b)在对反应呈惰性溶剂中,在叔胺的存在下,用式R9-SO2-Cl的磺酰氯将式(ⅩⅤ)化合物磺酰化,形成所述的式(ⅩⅢ)化合物,其收率超过90%。
本说明书中所用的“对反应呈惰性溶剂”一词是指这样一种溶剂,即:它不会同起始物、试剂、中间体或最终产物相互作用,有损于所期望产物的收率。
于是,可方便地制备本发明的各个非对映化合物。本发明的一个重要特征在于分别从式(Ⅻ)和式(ⅩⅢ)的已知旋光化合物制备上式(Ⅶ)和式(Ⅷ)的旋光母体。
为制备化合物(Ⅶa),首先将式(Ⅻ)化合物〔当R8=甲基时,为已知化合物;当R8不是甲基时,可按类似的方法制备〕同碱金属硫化物(较理想的是Na2S9H2O)反应,形成(S)-3-溴硫杂环戊烷(Ⅸa)。采用至少为一摩尔当量、通常为微量(例如5~10%)过量的硫化盐,以及对反应呈惰性溶剂,较为适宜的是水溶性溶剂,如(C1-C3)链烷醇水溶液(如甲醇水溶液)或乙腈水溶液。温度并不严格,例如0~60℃一般就可满足要求。特别有益的是,采用诸如17~28℃的室温,可降低加热和冷却所耗之成本,虽然高温可缩短完成反应所需的时间。
于是,利用大致为一摩尔当量的氧化剂(通常以微量过量使用,以实现不带有显著二氧化物的完全的单氧化,可方便地把中间体溴代硫杂环戊烷(Ⅸa)氧化成S-氧化物(Ⅸb)。适宜的氧化剂为间氯过苯甲酸和过氧单硫酸钾〔KHSO3·(KHSO4)·(K2SO4) 1/2 〕。氧化反应在对反应呈惰性溶剂中进行,CH2Cl2特别适宜于过苯甲酸,丙酮特别适于过氧单硫酸盐。温度并不严格,-10℃至40℃的温度一般便可满足要求。较为有益的是,在低温下,例如于0~5℃,将试剂合并,然后如上所述,于室温下完成该反应。
然后,在惯用的亲核置换条件下,将中间体亚砜(Ⅸb)同硫代乙酸碱金属反应,形成3R-(乙酰硫)硫杂环戊烷1S-氧化物(Ⅶb)。通常采用过量(如1.5~2摩尔当量)硫代乙酸盐,在对反应呈惰性溶剂中进行反应。所用的溶剂使两种反应物具相当高的浓度,以便在适当的时间内,促使这种双分子反应完成。就本发明而言,丙酮特别适于溶剂。温度并不严格,例如30~100℃便一般可满足要求了,当达到溶剂丙酮的回流温度时,尤其理想。
最后,通过硫醇盐(Ⅶ,Y=M4),将乙酰硫杂环戊烷(Ⅶb)转化成三硫代碳酸盐(Ⅶa),通常于低温下,例如在-15至+15℃、最好接近0℃时,在相应烷醇的对反应呈惰性溶剂中,经碱金属醇盐的作用,直接形成中间体硫醇盐。甲醇钠/甲醇、乙醇钠/乙醇和异丙醇钠/异丙醇均十分适于实现上述目的。一旦中间体硫醇盐形成后,不经分离,通常于更低的温度,如-40°至0℃,将其同至少为一摩尔当量的二硫化碳(通常以过量、如3~5摩尔当量使用)反应,形成所期望的式(Ⅶa)的3R-(硫代(硫羰基)硫)硫杂环戊烷-1S-氧化物。利用常规的方法分离后者,或者将其直接用于下一步。
为制备化合物(Ⅷa),利用上述由(Ⅻ)转化成(Ⅸa)的条件,首先将式(ⅩⅢ)的环氧化物同碱金属硫化物反应,形成式(Ⅺ)的(R)-3-羟基硫杂环戊烷。〔当R8=甲基时,式(ⅩⅢ)化合物是已知的;其他情况下可按照本说明书中公开的改进方法来制备。〕在常规的条件下,例如采用大致为一摩尔当量的相应磺酰氯、R8SO2Cl,在至少为一摩尔当量叔胺、最好是对二甲基氨基吡啶的存在下,在诸如二氯甲烷的对反应呈惰性溶剂中,于0~50℃的非临界温度,最好于上述室温下,将式(Ⅺ)的(R)-3-羟基硫杂环戊烷(Ⅺ)转化成式(Ⅹa)的烷烃、苯或对甲苯磺酸盐。然后将化合物(Ⅹa)氧化成亚砜(Ⅹb),将磺酸盐基基团同硫代乙酸盐进行亲核置换反应,形成式(Ⅷb)的3-S-(乙酰硫代硫杂环戊烷-1R-氧化物,水解成硫醇盐(Ⅷ,Y=M ),最后同CS2反应,形成三硫代碳酸盐(Ⅷa),所有反应都在上述将(Ⅸa)转化为(Ⅶa)各步反应条件下进行。
本发明的改进的制备上式(ⅩⅢ)的母体(R)-(2-甲磺酰氧基乙基)环氧乙烷的两步法采用了Cs2CO3,在室温下,于对反应呈惰性溶剂(如CH2Cl2)中进行(上述Shibata等所采用回流的NaOH水溶液),从而经常规的磺酰化后,得到具更高旋光性的所述化合物(ⅩⅢ)。
合成上述式(Ⅰ)和式(Ⅱ)化合物所需的第二母体是下式(ⅩⅥ)的3R,4R-4-乙酸基-3-〔1R-1-(甲硅烷基保护羟基)乙基〕-2-氮杂环丁酮
式中R6是普通的甲硅烷基羟基保护基(最好是二甲基叔丁基甲硅烷基),可通过Leanza等人在Tetrahedron,Vol.39,pp.2505~2513(1983)所述方法由6-氨基青霉烷酸可以高收率制备该化合物。这样,在合成的下一步,通过分别同三硫代碳酸盐(Ⅶa)或(Ⅷa)反应,便将氮杂环丁酮(ⅩⅥ)转化成式(Ⅴ)或(Ⅵ)的非对映化合物,其中R6为氢。在对反应呈惰性溶剂中,例如在诸如异丙醇的(C1-C3)链烷醇中,并且最好在与制备三硫代碳酸盐所用的同一溶剂中,在过量二硫化碳的存在下(所述二硫化碳已存在于上一步骤),对所述的三硫代碳酸盐进行分离,或不对其进行分离,便可将反应物汇合起来。该反应通常在低温(例如±20℃)下进行,最好于冰浴温度(0~5℃)进行。
然后将式中R7为氢的式(Ⅴ)或或(Ⅵ)化合物同下式(ⅩⅦ)的酰基氟反应,
形成式中R7为-COCOOR10的相应化合物(Ⅴ)或(Ⅵ)。式(ⅩⅦ)中R10如前所定义。这一步反应是在叔胺存在下、0°至-80℃时于惰性反应溶剂中进行的。比较理想是,采用低温,例如-30℃至-70℃。优择的对反应惰性溶剂是二氯甲烷;优择的叔胺是N,N-二异丙基乙胺。
在下一步的合成中,经过亚磷酸三烷酯(如亚磷酸三乙酯)的作用,由式中R7为-COCOOR10的式(Ⅴ)或(Ⅵ)化合物形成式中R4为甲硅烷基保护基、R5相当于R10的式(Ⅲ)或式(Ⅳ)的去青霉烯化合物。这一步的反应同样是在对反应惰性溶剂(如无乙醇的氯仿)中进行的。温度并不严格,但通常温度超过室温,(如40℃至80℃),并且当溶剂为氯仿时,最好为回流温度。
在最后的或倒数第二个步骤中,采用标准的方法,例如就二甲基叔丁基甲硅烷基而言,通过无水四氢呋喃中的乙酸和氟化四丁铵的作用,除去甲硅烷基保护基,形成式(Ⅰ)或(Ⅱ)的化合物,它们呈其新戊酰氧基甲酯的形式,或呈式(Ⅲ)或式(Ⅳ)的形式,式(Ⅲ)或式(Ⅱ)中R4为氢,R5为-CH2-CX=CH2。
最后,当R5为烯丙基或2-氯烯丙基时,将该酯水解,得到所期望的呈酸或其药物上可接受的阳离子盐形式的上述式(Ⅰ)或式(Ⅱ)的青霉烯。通常采用无水条件,以避免任何可能产生的β内酰胺的降解。优择的反应条件是:采用1至1.1摩尔当量的亲油羧酸的碱金属盐(如2-乙基己酸钠),在催化量的三苯基膦和四(三苯基膦)钯(例如0.15摩尔当量前者,0.075摩尔当量后者)的存在下,于无水对反应呈惰性溶剂(如二氯甲烷和/或乙酸乙酯)中反应。虽然温度并不严格,但最好在室温下进行反应。用上述试剂,通常最初分离到(Ⅰ)或式(Ⅱ)化合物的碱金属(如钠)盐。需要时,采用标准方法在分离期间或分离之后,将该盐的水溶液酸化,使盐转化成游离酸,并将游离酸提取到与水不溶混的有机溶剂中。
用标准方法也可容易地制得本发明的其他药物上可接受的阳离子盐。例如,于有机或含水溶剂中,最好在低温(如0~5℃)下,将等量的相应阳离子氢氧化物、碳酸盐或碳酸氢盐或等量的胺同羧酸混合,同时,剧烈搅动,缓慢地加入碱。经过浓缩和/或加入非溶剂添加物,将盐分离。
按青霉素领域内专业人员公知的方法(例如见美国专利3,951,954,4,234,579,4,287,181,4,342,692,4,452,796,4,342,693,4,348,264,4,416,891和4,457,924),从相应的游离酸或阳离子盐,同样可制得式中R代表能体内水解的酯的式(Ⅰ)或式(Ⅱ)化合物。就本发明的例子而言,优择的前体是式(Ⅲ)或式(Ⅳ)的羟基保护化合物。所述的化合物(Ⅲ)或(Ⅳ)中R4为甲硅烷基保护基、R5为氢或盐,最好是四丁铵盐。可通过上述特定的方法,选择水解相应的烯丙基或2-氯烯丙酯,制得所述的前体。最好先将得到的碱金属盐转化成四丁铵盐,然后同形成酯的试剂(如新戊酸氯甲酯或1-氯乙基碳酸乙酯)反应。形成酯的位择方法例举说明在下面。然后除去中间体化合物中的甲硅烷基保护基,得到所期望的式(Ⅰ)或式(Ⅱ)的化合物,其中R为能形成体内易水解的酯的基团。
所需要的酰基氟(ⅩⅦ)可由相应的酰基氯制得,其中采用了为实现上述目的试剂:无水氟化铯(通常在室温或接近室温下进行,试剂的混合最初在更低的温度,如0℃至-30℃进行),或氟亚磺酸钾(FSO2K,通常在较热的温度下,如45~85℃进行)。当R5为新戊酰氧基甲基时,采用后一试剂和条件较理想。
就用于本发明方法的其他起始原料而言,通过上述Leanza等人的方法可方便地得到,3R,4R-4-乙酸基-3-〔1R-1-(甲硅烷氧基)乙基〕-氮杂环丁酮;烯丙基苯酰氯可按Afonso等人在J.Am.Chem.Soc.,Vol.104,PP.6138~6139(1982)上所述的方法得到;2-氯烯丙基草酰氯可用下面详细介绍的方法,从2-氯烯丙醇和草酰氯制得;新戊酰氧基甲基草酰氯同样可通过下面详细介绍的方法,由草酸的苄基半酯和新戊酸氯甲酯,经若干步骤得到。
按上述Hamanaka的美国专利4,619,924所详细介绍的方法(这里用来引证),试验、配制和使用式(Ⅰ)和式(Ⅱ)纯非对映抗菌化合物。在人体用药剂量范围内,本发明化合物(Ⅰ)和(Ⅱ)较佳的剂量范围是10~80mg/kg/天,既可口服用药,又可非肠道用药。这些数字仅仅用来说明,因为在某些情况下经治医生会发现在这些剂量范围外用药,效果更好。能体内水解的酯,尤其是新戊酰氧基甲酯和1-(乙氧基羰基氧)乙酯较适合于口服使用,而钠盐或钾盐特别适合于非肠道用药。
以下实施例用于说明,而不构成对本发明的限定,在本发明的范围和精神内可对此作出许多变换。
