Description
本发明涉及制备具有生物活性的10-二氢-10-脱氧-11-氮杂红霉内酯A类化合物及其可药用的与酸形成的盐的方法。
众所周知,许多抗菌素除具有基本的抗菌作用外,还具有抗炎作用。但是,抗菌素的这种特性很少被用来治疗不是由病原微生物所引起的炎症。原因是要避免微生物过快地产生抗性和人体对它们可能产生的过敏。所以,有抗炎作用却无抗菌作用的物质一直是很需要的。这些物质的化学结构通常不同于抗菌素,或者在例外情况下,这些物质可用化学转化的方法从抗菌素获得。我们知道D-青霉胺就是由青霉素衍生而来的(见Abraham等,Nature,151,107(1943)和Ruiz-Torres,Arzneimittel-Forsch,24,914(1974))。
按照已知和确定的先有技术,先进行红霉素A肟的贝克曼(Beckmann)重排,然后将得到的红霉素A亚氨基酸还原,合成了10-二氢-10-脱氧-11-氮杂红霉素A(美国专利,4328334,5/1982,Djoki 等;J·Chem,Sco.Perkin Trans.1,1986,1881)。按照改良的埃谢韦勒-克莱克(Eschweiler-Clark)方法,将所得胺用甲醛在甲酸存在下还原甲基化,制得N-甲基-11-氮杂-10-脱氧-10-二氢红霉素A(英国专利,2094293,Kobrehel和Djoki ),这是一种新的15员氮杂环内酯的半合成大环内酯抗菌素;这种抗菌素已以迭氮斯罗霉素(azithromycin)的属名进行了临床试验。美国专利4464527(84)叙述了获得10-二氢-10-脱氧杂红霉素A的N-乙基和N-正丙基衍生物的方法。这些衍生物也是有效的抗菌剂。
申请者对先有技术的检索表明,目前还无人报道过10-二氢-11-氮杂红霉内酯A类化合物,尤其是它们的N-烷基衍生物、它们的盐和/或O-和/或N,O-取代的烷酰基衍生物。
本发明旨在提出制备化合物10-二氢-10-脱氧-11-氮杂红霉内酯A(式Ⅰ)及可选择制备的其可药用的与酸形成的盐的方法。结构式(Ⅰ)中,R1代表氢原子、低级烷基或低级烷酰基;R2、R3和R4可以相同也可不同,各自代表氢原子或低级烷酰基。
这一方法包括:
A)使10-二氢-10-脱氧-11-烷基-11-氮杂红霉素A(式Ⅱ)经一步或二步水解,在
式Ⅱ中,R1意义同上,R′ 2代表德糖胺基,R′ 3代表克拉定糖基,R′ 4代表氢原子;
或B)使10-二氢-10-脱氧-11-氮杂红霉内酯A(式Ⅲ),在甲酸的存在下,或者在氢及贵金属催化剂的存在下,与式Ⅳ的脂肪醛反应,在式Ⅳ中,R5代表氢或低级烷基(最好是C1-C3烷基);
和C)如果需要,可将按A)或B)获得的产物用低级脂肪酸酐,最好是C1-3脂肪酸酐进行酰化,并且如果需要,可将按A)、B)或C)得到的产物转化成可作药用的与酸形成的盐。
本发明方法步骤A的水解可以一步完成,也可以二步完成,一步水解具体可以先用高浓度无机酸在惰性溶剂(如氯仿)存在下,加热回流16至60小时,然后在pH值为8至9的条件下,用同一溶剂萃取将产物分离出来。二步水解包括:ⅰ)在室温下,用稀的无机酸将式(Ⅱ)化合物水解10至20小时,然后用有机溶剂(如二氯甲烷、氯仿或乙醚)在pH值为9至11条件下萃取中间产物6-0-德糖胺基-10-二氢-10-脱氧-11-烷基-11-氮杂红霉素A(式Ⅴ),式中R1、R2′意义同上。
ⅱ)接着按上述“一步”方法水解已分离的中间产物(Ⅴ)。
将化合物Ⅲ还原烷基化的本发明方法B)可按下面两种方式之一进行:B1)使化合物Ⅲ在惰性溶剂中,于甲酸存在条件下,与甲醛反应;B2)使化合物Ⅲ在惰性溶剂中,于氢和贵金属催化剂存在下,与式Ⅳ的醛反应。
按照本发明的B1)方法,在反应混合物的回流温度下,于惰性溶剂(如丙酮、卤代烷(最好是氯仿))中,在至少等量的甲酸存在下,使化合物Ⅲ与过量1-3摩尔的甲醛反应2-8小时,得到化合物Ⅰ(其中R1为甲基,R2、R3和R4各自代表氢原子)。
B2)方法是在惰性溶剂〔如甲醇或乙醇(96%m/m)等低级醇〕中,于贵金属存在下,用式Ⅳ的醛和氢将化合物Ⅲ还原烷基化。具体反应条件是醛过量1-2倍摩尔,贵金属催化剂(最好是钯-炭(5%m/m))为0.5至等摩尔量。还原烷基化反应是在温和的温度下(如18至25℃)和在初始氢压为10至30巴的条件下进行2至10小时。反应完成后,滤去催化剂,然后用常规方法分离产物,最好是在减压条件下蒸发乙醇,再用惰性有机溶剂(如二氯甲烷、氯仿或四氯化碳)萃取水悬浮液,从而使式(Ⅰ)产物分离,式(Ⅰ)中,R1代表低级烷基,R2、R3和R4均为氢原子。
酰化步骤则可按通用的酰化方法(如Jones等,J.Med.Chem.,15,631(1972)进行。
具体的一组式(Ⅰ)化合物是式ⅠA的新10-二氢-10-脱氧-11-氮杂红霉内酯A化合物及其可作药用的与酸形成的盐,
其中R′ 1表示除氢原子以外的R1,R3和R4意义同上。
式(Ⅴ)中间体也是新的化合物。
应该指出,当R1为氢原子时,化合物(Ⅰ)本身属于先有技术(见前述S.Djoki 等,J.Chem.Soc.,PerkinTrans,I,1986,1881);但本申请人已经发现了它们的新的、明显改进的制备方法(根据上述方法A)和医药用途,这些目前仍是未知的。10-二氢-10-脱氧-11-氮杂红霉丙酯A(式Ⅰ)的可作药用的与酸形成的盐也包括在本发明范围内,其制备方法是:使至少等摩尔量合适的酸(如盐酸、氢溴酸、硫酸、磷酸、醋酸、丙酸、柠檬酸、琥珀酸和苯甲酸等)与10-二氢-10-脱氧-11-氮杂红霉内酯A类化合物(式Ⅰ)反应,此反应可选择在于此反应的条件下为惰性的溶剂中进行。与酸形成的盐的分离方法有:若它们不溶于所用的惰性溶剂,就采用过滤法;加入不溶解相应盐的溶剂使该盐沉淀出来;或者蒸发溶剂,最常用的是冷冻干燥法。
根据体外和体内研究发现,上述式(Ⅰ)化合物具有十分显著的抗炎作用。用人体多形核白细胞的溶酶体酶细胞外释放的模型(Weissman等,J.Exp.Med.,134,149(1971);Carevi ,Agents and Actions,16,407(1985),通过与已知的抗炎药物双氯芬酸(DICL)和D-青霉胺(D-PEN)进行比较,测定了它们的体外抗炎作用,结果见附图1和2。
图1明显表明,将迭氮斯罗霉素(azithromycin)水解并制备相应6-0-德糖胺基衍生物(DESAZ)得到了具有良好抗炎活性的产物。DESAZ在10-5浓度条件下与浓度为10-7的D-PEN具有大约相等的活性,通过消除双糖基并合成10-二氢-10-脱氧-11-甲基-11-氮杂红霉内酯A(AZER),得到了能显著抑制溶酶体酶从多形核白细胞的细胞外释放的化合物,其活性与D-PEN相近,在浓度为10-7,则活性更强,
在体外试验中,DICL并不影响酶的细胞外释放N-乙基-(AE)或N-(正丙基)衍生物的体外活性与AZER相比要稍低些(见图2)。AZER可以与乙酸酐进行酰化反应,并且制得的4,6,13-三乙酰基-10-二氢-10-脱氧-11-甲基-11-氮杂红霉内酯A(ALA-3)的试管活性无明显的变化。
还对大白鼠进行了佐剂引起的关节炎模型的体内研究(Per-ason等,Arthritis Rhem.,2,440(1959);Carevi ,Dubl Yug.Acad.of Sci.7,415(1985))。图3的结论是,对于佐剂引起的关节炎的大白鼠,AZER可以显著减少溶酶体酶由细胞外释放进入大白鼠的滑液,AZER的活性水平与D-PEN相当而明显高于DICL。DESAZ的活性稍低于D-PEN和DTCL。
以上结果显然说明体内方法与体外试验是可比的。在这些试验中,体外和体内研究的受试物质都没有显著地影响乳酸脱氢酶(A)的释放,这证明细胞膜没有受到明显的影响。
还用角叉菜胶引起的大白鼠爪水肿(Crunkhorn等,Br.J.Pharm.,42,392(1971))测定了抗炎作用。
化合物(Ⅰ)所得结果(30-40%)没有明显超过D-PEN和Acisal(35-45%)。N-乙基和N-(正丙基)衍生物(Ⅰ)的活性与AZER的抗炎活性属同一水平。但是,与D-PEN比较,O-和/或N,O-取代的化合物(Ⅰ)及其盐具有较强的活性。
