Abstract
本发明涉及通式(I)的利福霉素衍生物盐的制备方法。式(1)中B代表无毒性的、药理上适宜的无机或有机碱。
Description
已知利福霉素类是一类重要的抗菌素，特别是其中的利福平，因其口服后具有强抗菌作用及高生物药效率，从而成为治疗分支杆菌属（例如结核杆菌）感染的首选药物。
在我们的意大利专利20278/83及其它专利如美国专利4，562，203中，我们主要介绍并要求专利保护的是一种新的利福霉素衍生物-3-[（1-二乙基氨基亚乙基）连氮甲基]利福霉素SV，其具体结构如下式所示（其中B为氢）：
此衍生物对于多种分支杆菌属菌株及其它革兰氏阳性菌和部分革兰氏阴性菌具有强抗菌作用;这种抗菌作用的平均强度与利福霉素本身相当，或甚至更高一些。
B为氢的式（Ⅰ）化合物的药理动力学特性明显优于利福霉素，因为它在多种动物的血液中都有较长的半寿期，这说明它能随血液循环较长的时间，从而其体内效果更好。
以下药理动力学评价参量，即口服后的最大血液浓度平均看来和利福
霉素相似，这证明B为氢的式（Ⅰ）化合物在各种实验动物体内的生物药效率与利福平相近。
我们发现预先使B为氢的式（Ⅰ）化合物成盐而得到B为无毒性的、药理上适宜的无机或有机碱的式（Ⅰ）化合物，可显著改善其生物药效率。
这些盐-本发明的目的物-是到目前为止在临床文献中还未见到的新化合物。
优选的成盐产物是用碱金属碱、氨基酸，或甚至用简单有机胺制得的盐，例如钠盐、赖氨酸盐和三乙胺盐。
所有这些成盐方法已证明都适用于将基本不溶于水的酸式产物（式Ⅰ，B＝H）（因而它易于通过胃肠道而至少有一部分没有改变，只是有限地被吸收）转变为极易溶于水的盐，由此便创造了提高其生物药效率的必要条件。还应考虑到，尽管成盐物质的良好水溶性是必需的，但一般仍不足以保证，成盐物质本身在口服后能被充分吸收，这是因为胃酸可以使盐本身分解并使不溶性结晶物形式的相应酸再次析出。所以这些盐的生物药效率得以改善的原因这样解释更加确切：在上述情况下，该酸性物质在胃中沉淀析出后成为无定形的、极细的分散物质，所以进入碱性的肠道环境后更可溶且/或更易于溶解。
撇开上述盐的生物药效率得以大大提高的内在物理化学和生物化学机制不谈，根据对不同种动物以至最后对人所做实验的结果（参见例示性的表1），都表明：在给药剂量相同的情况下，盐形式的利福霉素衍生物在血液中的浓度水平比酸形式产品高得多。

不言而喻，在应用式（Ⅰ）的新的利福霉素衍生物的水溶性盐时，可将该衍生物配制成可注射的制剂，而未盐化、因而不溶解的产品不可能如此。
式（Ⅰ）的盐按以下方法易于制得：使几乎等摩尔量的酸式式（Ⅰ）化合物（B＝H）和适宜的碱在水或在有机溶剂如乙醇中进行反应。
上述盐的制备还可以选择在少量抗坏血酸或其盐存在下进行，这是为了利用其已知的还原能力防止利福霉素衍生物可能转变成醌的形式。制得的盐易按以下方法分离：在含水介质中进行制备时，可将所得溶液蒸干或冻干;或者用其它适宜的有机溶剂使盐从溶液中沉淀出来。
必要时，可将分离出的产物用结晶或其它常用的方法进一步提纯。
为了更好地说明而非用以限制本发明，现给出以下制备实例。
例1
将5.0克3-[（1-二乙氨基亚乙基）连氮甲基]利福霉素SV（I，B＝H）悬浮于20毫升乙醇中，再加入60毫克溶于1毫升水中的抗坏血酸钠以防止形成少量氧化产物（即醌式的利福霉素）。在搅拌下，向所得悬浮液中加入等摩尔量（323毫克）的甲醇钠，于是该游离酸因转化成相应的钠盐而很快地溶解。滤除少量不溶物（实际上是抗坏血酸钠），在减压降温下蒸干滤液，得到结晶状残余物，其产率几乎是定量的。该残余物即3-[（1-二乙氨基亚乙基）连氮甲基]利福霉素SV的钠盐（I，B＝Na），基本上是纯的。若需要，此产物可用异丙醇（50毫升）结晶而进一步纯化;结晶产率可达90%以上。此化合物为橙红色固体，易溶于水，可溶于甲醇、乙醇、丙酮、乙酸乙酯、氯仿，不易溶于异丙醇，不溶于乙醚及石油醚。加热时，在210℃开始发生碳化，甚至在更高温度下也不熔解，分光光度分析（采用0.1%甲醇溶液，再用pH6的磷酸盐缓冲液稀释至0.02毫克/毫升）表明在231、261、338、485毫微米处有吸收峰。
元素分析（C44H59N4O12Na;分子量858.95）
C、H、N在实验误差范围内（＜0.5%）
Na（用0.02N盐酸滴定）＝99.6%
例2
将5.0克3-[（1-二乙氨基亚乙基）连氮甲基]利福霉素SV（I，B＝H）悬浮在100毫升水中（悬浮液pH＝5.2），再于搅拌并冷却至5～10℃的条件下使之与5.97毫升1N氢氧化钠反应，后者是约用3小时时间小心滴加到悬浮液中的。产物逐渐缓慢地溶解，过滤澄清最后得到的溶液（pH9.9），用冷冻干燥法将其蒸干，得到定量的所要制备的盐（I，
B＝Na）;该盐为无定形橙红色粉末，同例1方法制得的产品相似。
例3
把1.0克3-[（1-二乙氨基亚乙基）连氮甲基]利福霉素SV（I，B＝H）悬浮于10毫升水中，再向悬浮液内加入等摩尔量的D，L-赖氨酸（即0.32毫升50%的D，L-赖氨酸水溶液）。上述利福霉素衍生物迅速完全溶解。然后过滤使溶液变清并在减压降温条件下将其蒸干。从而得到所要制备的赖氨酸盐（I，B＝D，L-赖氨酸·H），产率几乎是定量的。该盐为红色结晶状固体。
要是愿意，可用适宜的异丙醇/异丙醚混合液将该产品进一步提纯。
分析：C50H74N6O14（分子量983.17）
C、H、N在实验误差范围内（＜0.5%）
碱测定值（base assay）＝99.4%
