Description
发明背景
本发明涉及一种制备高纯度的吲哚并咔唑苷的新方法,吲哚并咔唑苷抑制肿瘤细胞的生长,因此被用于治疗哺乳动物的癌症,等等。
在癌症化学治疗领域,大量化合物作为抗肿瘤剂已经应用于实际中。然而,仍然需要不断开发更有效的化合物以对抗各种肿瘤(参见日本癌症协会第47届大会会刊,第12-15页(1988))。这种需要导致了吲哚并咔唑衍生物的开发。(参见美国专利号4,487,925;4,552,842;4,785,085;5,591,842和5,922,860;日本专利号20277/91;Journal of Antibiotics,Vol.44,pp.723-728(1991);WO91/18003;WO98/07433;以及EP0545195A1)。这些化合物已经作为拓扑异构酶抑制剂使用并因此用于治疗癌症(Cancer Chemother.Pharmacol.34(附加):S41-S45(1994))
这些化合物在治疗许多癌症上的成功使得有必要改进它们的合成方法。(参见Bioorg. & Med.Chem.Letters 2000,10,419;Tetrahedron 1997,53,5937;Tetrahedron 1997,53,585;和Synthesis 1976,414)。然而,以前已知的方法遇到许多的问题,包括使用不希望的溶剂,汞或银盐,低收率以及不需要的副产物的生成,使其不得不进行冗长的提纯步骤。
例如,以前已知的制备高纯度吲哚并咔唑苷III的方法需要提纯步骤,例如活性炭处理、色谱分离法和/或原料的重结晶,由于产物非常高的细胞毒性,特别是当大规模时,该提纯步骤是冗长的、费时的并且危险的。(参见Bioorg & Med Chem Letters 1999,3307;和Tetrahedron 1997,585描述在结构上相似的化合物的合成,需要再溶解粗产品以得到纯的物质))。
因此本发明的目的是提供一种新的合成吲哚并咔唑衍生的抗癌物质的路线,以克服以前已知的合成方法中存在的问题。具体地说,由该路线制得的足够纯的产品在后面的配方中可以按“原状”使用。

(g)分离化合物III的晶体。
在第三个实施方案的另一个的实施方案中,该方法还包含脱保护中间体II:
(其中R独立地是氢或取代或未取代的苄基保护基,条件是至少一个R是取代或未取代的苄基保护基),通过在催化剂存在下的氢化反应以制备反应混合物,接着过滤反应混合物以得到步骤(a)的混合物。
在上面刚描述的另一个实施方案中,在步骤(a)中,将pH值调节到约1.5-约3.5的范围内;在步骤(b)中,调节溶液,以使其为约15%w/v-约25%w/v水的醇溶液,并且化合物III的浓度约为12mL/g-18mL/g;在步骤(c)中,将溶液的温度调节到约70℃。

将10%钯/碳(50%湿的;112克)加入5加仑高压釜中,接着加入12-β-D-(2,3,4,6-四-邻苄基吡喃葡萄糖基)-12,13-二氢-2,10-二苄氧基-6-[[-(2-苄氧基-1-(苄氧基甲基)乙基]氨基]-5H-吲哚[2,3-a]吡咯[3,4-c]咔唑-5,7(6H)-二酮(3-1)(175克/升溶液;6.4升;1.12公斤)的THF(四氢呋喃)溶液、异丙醇(IPA)(7.9升)和3NHCl(224毫升)。将物料在40℃/40psi以及快速搅拌下氢化反应4-14小时,在此期间,理论值的110%的氢被吸收。将物料冷却至25℃,用solka絮凝物床过滤反应混合物,并用3/2的IPA/THF(1×3升)冲洗滤渣。用在IPA(约600毫升)中的1M的三乙胺调节滤液的pH至2.5(范围:1.5-6.5),接着加入水(4.0升)。在大气压下将该批物料浓缩至7.5升。在恒定分批体积下进行蒸馏,同时加入4/1的IPA/水(6.5升)。在保持分批体积为7.5升的同时,通过加入IPA(约9升),将含水量降至20%(w/v)(范围10-30%的水)。然后将物料冷却至70℃,并且将晶种以IPA淤浆(50毫升)的形式加入。分批在70℃保温1小时,接着在90分钟内加入IPA(5.0升)。该批物料在70℃陈化9-24小时,在此期间,大块的产品晶体析出。进行恒容蒸馏,蒸馏期间加入IPA(17升)以保持体积恒定,得到含水量低至3%(w/v)(范围1-10%的水)的淤浆。将淤浆在70℃陈化3-6小时,接着冷却至22℃并陈化1小时。过滤淤浆,滤饼用IPA(2.5升),然后用甲醇(1.5升)进行洗涤,接着在真空中于38℃进行干燥6小时,得到纯度大于99A%、收率大于80%的橙色固体产品4-1。
