Description
本发明是关于7-(二甲氨基亚甲基)氨基-9a-甲氧基米托沙奈(mitosane)的一种新结晶形式,这种结晶甚至在温度达到100℃时也是稳定的。
丝裂霉素C是一种经发酵生产的抗生素,经美国药品和食品管理局批准,现今在市场上销售,它与其它已批准的化疗药物合用,作为缓解疗法,用来治疗那些用其它手段无效的胃或胰脏的播散性腺癌(Mutamycin
布里斯特实验室,西拉库斯,纽约13201,《内科医生手册》,第38版,1984年,第750页)。丝裂霉素C及其发酵产品是1972年5月2日授于的美国专利No。3,660,578的主题,所要求的优先权是根据包括1957年4月6日在日本提出的申请在内的早期申请。
丝裂霉素A、B、C和紫菜霉素的结构首先由美国氰胺公司里德勒实验部的J.S.Webb等人发表于美国化学会志84,3185-3187(1962)。在研究丝裂霉素A和丝裂霉素C结构中所用的一种转化反应是将前者即7,9a-二甲氧基米托沙奈,与氨反应转变成后者,即7-氨基-9a-甲氧基米托沙奈。丝裂霉素A的甲氧基的置换作用在制备丝裂霉素C的有抗肿瘤活性的衍生物中,具有相当的重要性。下面的文章和专利都涉及到丝裂霉素A转变成具有抗肿瘤活性的7-取代的氨基丝裂霉素C衍生物。

在7位上有取代的氨基取代基的丝裂霉素C衍生物也可由定向的生物合成方法制备,这就是向培养基中补充一系列的伯胺,并进行常规的丝裂霉素发酵(C.A.Claridge等,美国微生物学年会摘要,1982,摘要号028)。
比利时专利No.896,963,这儿提出该专利作为参考,它公开了丝裂霉素C的一组单胍基或单一和双一脒基类似物,其中丝裂霉素C的7-氨基和N10-氨基甲酰基中的一个或两个氮原子是脒取代基的一部分或7-氨基氮是胍基的一部分。这样的一种化合物,其制备方法如在该比利时专利的实例8和15中所述,是具有如下结构的化合物7-(二甲氨基亚甲基)氨基-9a-甲氧基米托沙奈:
该化合物为无定形固体,具有较高的抗P388小鼠白血病活性,就最大效果和微克活性而言(同等效应比较剂量大小),超过了丝裂霉素C。然而,在25-56℃时,它通常是不稳定的。
现已发现结晶形式的7-(二甲氨基亚甲基)氨基-9a-甲氧基米托沙奈甚至在温度达100℃经6天或更长的时间仍是稳定的。它的红外光谱图如附图。在贮存中它的稳定性比无定形的7-(二甲氨基亚甲基)氨基-9a-甲氧基米托沙奈强得多。
无定形7-(二甲氨基亚甲基)氨基-9a-甲氧基米托沙奈的制备,是按照比利时专利No.896,963中实例8和15的方法。这些方法叙述如下:
比利时专利No.896,963的实例8的方法
化合物Ⅰ,7-〔(二甲氨基)亚甲基〕氨基-N10-(二甲氨基)亚甲基-9a-甲氧基米托沙奈的制备如下:
将总量为9.6ml(于0,18,21和23小时各加入2.4ml)的N,N-二甲基甲酰胺二甲基缩乙醛加到500mg(1.50mM)的丝裂霉素C于25ml氯仿悬浮液中。在大约50℃下搅拌该悬浮液41小时。减压下蒸除溶剂和过量的试剂,得到暗绿色的残留物;薄层层析显示(二氯甲烷/甲醇20∶1展开)丝裂霉素C不复存在,而出现两个新的绿色成分(Rf=0.16和0.22)。用快速色谱法分离主成分(Rf=0.16),用二氯甲烷/甲醇(20∶1)作为洗脱剂,得到的绿色固体(340mg51.5%)溶解于乙醚中,加入己烷,得到暗绿色无定形粉末状化合物Ⅰ。

7-(二甲氨基亚甲基)氨基-9a-甲氧基丝裂烷(Ⅱ)的制法如下:
将2.2ml氨基二苯基甲烷(10.8mM)加到化合物(Ⅰ)(600mg,1.35mM)溶于10ml甲醇的溶液中,得到的溶液在54℃搅拌4小时。反应进程用薄层层析监测(二氯甲烷/甲醇90∶10)。于4小时终结时原料(Rf=0.35)已消失。代之出现一主要为绿色的新谱带(Rf=0.29)。减压下浓缩该溶液,得到的糖浆状残留物经快速色谱法提纯(25g硅胶),用二氯甲烷/甲醇20∶1作洗脱剂。合併含有绿色成分Rf=0.29的组分,Na2SO4干燥后浓缩,得到化合物Ⅱ,为无定形固体(215mg,41%)。

1.57g草酰氯(12.5mmol)于0℃下滴加到二甲基甲酰胺(915mg,12.5mmol)于25ml氯仿的溶液中,室温下搅拌30分钟,得到0.5M的氯化N,N-二甲基氯甲基亚铵溶液。另外,将丝裂霉素C(334mg,1mmol)于5ml二甲基甲酰胺的溶液加到氢化钠(36mg,1.5mmol)于3ml二甲基甲酰胺的悬浮液中。所得溶液在室温下搅拌20分钟后冷却到-40℃到-50℃,然后将上面制备的氯化N,N-二甲基氯甲基亚铵(3ml,1.5mmol)加入。于-40℃搅拌10分钟后再加氢化钠(18mg,0.75mmol)。该溶液在-40℃下保持1小时后,用二氯甲烷稀释,过滤。蒸发滤液,得到的残留物在硅胶板上进行薄层层析(10%CH3OH-CH2Cl2作为洗脱剂)。分离出主要的绿色谱带,得量为78mg(扣除回收的丝裂霉素C后的收率为43%),呈无定形固体,它的核磁共振谱和薄层层析性质与上述制备的化合物Ⅱ相同。
将无定形的7-(二甲氨基亚甲基)氨基-9a-甲氧基米托沙奈溶于丙酮和/或甲醇中,并向该溶液中加入乙醚,则转化成结晶形式。乙醚的加入最好维持一定的时间,例如20分钟,另一个制备结
晶形的7-(二甲氨基亚甲基)氨基-9a-甲氧基丝裂烷的方法,是把一定量的无定形的7-(二甲氨基亚甲基)氨基-9a-甲氧基米托沙奈制成乙醚糊状物,然后向其中加入小量的结晶形的7-(二甲氨基亚甲基)-氨基-9a-甲氧基米托沙奈。这就使无定形的7-(二甲氨基亚甲基)氨基-9a-甲氧基米托沙奈转化成结晶形式。
下面的实例详细说明了结晶形的7-(二甲氨基亚甲基)氨基-9a-甲氧基米托沙奈的制备方法。
实例1
1.0g无定形的7-(二甲氨基亚甲基)-氨基-9a-甲氧基米托沙奈的游离碱溶于10ml丙酮中。在迅速搅拌下,20分钟内将该丙酮溶液加到100ml乙醚中。在密闭系统中在20-25℃,24小时中结晶形物质成糊状物。然后真空滤出暗绿色的结晶。该结晶用10ml乙醚和15ml石油溶剂B(Skellysolve-B)洗涤,于40℃下高真空干燥24小时,得量0.75g。

实例2
1.0g无定形的7-(二甲氨基亚甲基)氨基-9a-甲氧基米托沙奈游离碱于10ml乙醚的糊状物中,加入少量由实例1所得的结晶形7-(二甲氨基亚甲基)氨基-9a-甲氧基米托沙奈的2mg。此糊状混合物于密闭系统中20-25℃保持48小时。然后真空过滤得到的暗绿色结晶。该结晶用10ml乙醚和15ml石油溶剂B洗涤,并于40℃高真空下干燥24小时。得量0.9+g。该结晶产物的性质与实例1得到的产物的性质相同。
用以下方法测定结晶形7-(二甲氨基亚甲基)氨基-9a-甲氧基米托沙奈的稳定性:将精密称量的5-25mg的7-(二甲氨基亚甲基)氨基-9a-甲氧基米托沙奈放到所需数目的1.77克重螺盖小瓶内。将含有精密称量的7-(二甲氨基亚甲基)氨基-9a-甲氧基丝裂烷的螺盖小瓶放到温度不同的地点。在每个时间-温度间隔上,用高压液相色谱测定含有预先称量的7-(二甲氨基亚甲基)-氨基-9a-甲氧基米托沙奈的小瓶样品。测定的7-(二甲氨基亚甲基)氨基-9a-甲氧基米托沙奈的活度,用mcg/mg表示。结果列于表1。该表中括弧中的数值是无定形的7-(二甲氨亚甲基)
氨基-9a-甲氧基米托沙奈损失的百分数。
