11β-(4-异丙烯基苯基)-17β-羟基-17-氰甲基-4,9-雌二烯-3-酮。
本发明通式Ⅰ的11β-(4-异丙烯基苯基)-4,9-雌二烯的制备方法是用已知方式将通式Ⅱ的化合物经受酸性试剂的作用,从而游离出受保护官能团并选择性分裂出5α-羟基,同时构成4(5)-双键且必要时将17位和/或R3′中的自由羟基酯化或将R3′中的自由羟基醚化。
其中R1同上述定义,K为酸性介质中可水解的酮保护基,R2′和R3′同上述R2和R3定义,其中前述的羟基必要时可受到保护。
通式Ⅱ起始化合物是用通式Ⅲ的环氧化合物制得的
其中R1和K同上述定义且其中的K最好为酮缩醇;酮缩硫醇,肟或甲基肟构型,R3″为氢原子或-C=C-(CH2)m-OU,基中m=1~4,U为对酸不稳定的羟基保护基(DE-OS3347 126A1)。
导入11β-(4-异丙烯基苯基)并同时形成△9.10-5α-羟基结构单元的方法与欧洲专利申请公开No57115和110434所述方法相似,即用相应的芳基镁卤化物通过Cu(Ⅰ)-催化的格利雅反应来进行(Tet rahedron Letters,1979,2051)或通过相应的Ar2CuLi或Ar2Cu(CN)Li
一类的高铜酸盐或杂铜酸盐转化来进行(J.Amer.CHem.Soc.103,(1981)7672)。
所得通式Ⅱ化合物,其中R1和K同上述定义,R2′和R3′同R2和R3定义,其中的羟基必要时可受到保护,必要时在将C-17-取代基R3″转变成通式Ⅰ最终产品所要求的R2和R3的C-17-取代构型之后,紧接着用酸或酸性离子交换剂进行处理以选择性分裂出水,并形成4(5)-双键,同时脱掉其中的保护基。酸处理按已知方法进行,其中将通式Ⅱ化合物溶于可与水混合的溶剂如甲醇,乙醇或丙酮水溶液中,并使催化量的无机酸或磺酸如盐酸,硫酸,磷酸,高氯酸或对甲苯磺酸或有机酸如乙酸处理该溶液直至分裂出水并脱掉保护基。该转化过程也可用酸性离子交换剂进行,温度为0~100℃并且可用例如薄层色谱法进行取样分析试验。
在有K和R3′或K和R3″的通式Ⅱ和Ⅲ中包括的保护基为酸性介质中易于分裂的基团如亚乙二氧基酮缩醇,亚乙二氧基酮缩硫醇,2,2-二甲基三亚甲二氧基酮缩醇,肟基,甲氧基亚氨基,四氢吡喃基,甲氧甲基或甲氧乙基。
R3′氢原子被其它的R3′基团取代是按构成C-17-侧链的常规方法通过由C-17-羟基官能团的奥彭瑙尔氧化作用得到的17-酮的亲核加成和后续反应来完成的(“Terpernoids and Steroids,Spe-cialist Periodical Report,The Chemical Society,London,Vol.1~12)。
HC=CY的亲核加成,在Y=氧,(C1-C4)烷基或卤素时,是借助通式MC=CY的化合物来进行的,其中Y同上述定义,M为碱金属。
相应的炔烃用碱处理可制得金属有机化合物。因此,例如通过甲基或丁基锂在适宜的溶剂优选为二烷基醚,四氢呋喃,二噁烷,苯或甲苯中对相应的炔烃作用就可生成碱金属炔化物。
为制得17-氯乙炔基化合物,可就地由1,2-二氯乙烯和碱金属的醚溶液如甲基或丁基锂的醚溶液制成金属有机氯乙炔基化合物,并在溶液如四氢呋喃或二乙醚中与17-酮反应。17-卤乙炔基化合物也可通过卤化相应的乙炔基离析物而制得(Angew.Chem.96,720(1984))。
在17位导入3-羟基丙炔或丙烯是通过17-酮的反应来完成的,与炔丙醇的两个阴离子如与就地生成的炔丙醇的二钾盐反应制得17-[3-羟基丙炔-1-基]-17β-羟基化合物或与3-羟基丙炔的金属衍生物如与3-(四氢呋喃-2′-基氧基)丙炔-1-锂制得17-(3-(四氢呋喃-2′-基氧基)丙炔1-基)-17β-羟基化合物,还可随即进行氢化。这可在例如通过在溶剂如甲醇,乙醇,丙醇,四氢呋喃或乙酸乙酯中添加改性贵金属催化剂如铂或钯的情况下进行常温常压氢化来顺利完成。
同系的羟基炔基或羟基烯基的导入可以与炔丙醇相似的方法进行。
羟基-烯基侧链中具有Z-构型双键的化合物可用钝化的贵金属催化剂氢化相应的炔结构来完成(J.Fried,J.A.Edwards:OrganicReact ions in Steroid Chemistry,Van Nostrand Reinhold Com-pany 1972,Seite 134;H.O.House:Modern Synthet ic React ions 1972,Seite 19)。作为钝化贵金属催化剂可用添加胺的10%钯-硫酸钡或添加乙酸铅(Ⅱ)的5%钯-碳酸钙。在取出1当量的水后中止氢化。
烯基侧链中具有E-构型双键的化合物可按已知方法还原炔结构来完成。文献中已报道了一系列链炔转化成反式烯烃的方法如还原反应,可用氢化锂铝(J.Amer.Chem.Soc.89,(1967)4245),用二异丁基氢化铝和甲基锂(J.Amer.Chem.Soc.89,(1967)5085)或在弱酸性介质中在水或二甲基甲酰胺存在下用硫酸铬(Ⅱ)(J.Amer.Chem.Soc.86.(1984)4358)或一般在交替氧化情况下借助过渡金属化合物的作用进行还原反应。
在17位引入3-羟基丙烷可通过17-酮与3-卤代丙醇的金属衍生物反应完成,其中在金属化过程中羟基作为醇化物(Tetrahedron Letters 1978,3013)或作为受保护官能团而存在,反应后形成17-(3-羟丙基)-17β-羟基化合物或末端羟基受保护的化合物。上述R3′或R3″的类似保护基适于此。
还可以类似于3-卤代丙醇的相应方式引入同系羟烷基。
17-氰甲基侧链的构成可按已知方法用17-酮完成,如按Z.Chem.18(1978)259用17-螺环氧化物并用HCN使螺环氧化物分裂。
17位和表示R3′的基团中的自由羟基可按已知方法酯化或醚化。
通式Ⅰ的新型化合物是很有价值的药物,对孕激素受体具有很强的亲合力,而自身又不具有孕激素活性。这些化合物为孕酮的竞争性拮抗药(抗孕激素)且适于诱导流产,因为这些化合物可排除受体中维持妊娠所必须的孕酮。因可用于调节性交后的生育力,所以这些化合物是非常有价值的有效药物。
也可针对激素的不均匀性而用其诱发月经以及流产。
此外,还可用其治疗与激素有关的癌症。
本发明通式Ⅰ化合物还显示出抗糖皮质激素活性,因而还可用作治疗皮质激素诱发的障碍(青光眼),并用于防治长期治疗过程中随糖皮质激素出现的副作用(柯兴氏综合症)。因此,这些化合物还可防治因糖皮质激素分泌过多而伴随的障碍如肥胖症,动脉硬化,高血压,骨质疏松,糖尿病以及失眼等。
还发现,通式Ⅰ的新型化合物不但出人意料地具有非常好的抗孕激素和抗糖皮质激素功效,而且其中还可观察到这两种作用是分别行使的。
为确定其抗孕激素特征而检定了其流产功效。
试验是用重约200g的雌鼠进行的。在成功地进行交配之后通过检定阴道涂片上的精子而保证已妊娠。有精子显示的当天作为妊娠的第1天(=dlp.c.)。
在胚囊着床d5p.c.至d7p.c.之后用每一种试验物质以及溶剂对这些动物进行试验。后于d9p.c.将动物致死并检查子宫内的植入体和吸收状况。然后对整个子宫拍照。把植入体缺损视为流产。
将试验药物溶于苯甲酸苄酯-蓖麻油混合物(混合比1+9)。每次剂量的溶剂体积为0.2ml。皮下(s.c.)给药。
本发明化合物的优越性还应就本发明化合物17-(3-羟基丙烯-1(Z)-基)-17β-羟基-11β-(4-异丙烯基苯基)-4,9-雌二烯-3-酮(A)的生物活性与EP82400025.1所述的11β-(4-二甲基氨基苯基)-17β-羟基-17α-(丙炔-1-基)-4,9(10)-雌二烯-3-酮 RU38486(B),EP84101721.3所述的11β-(4-二甲基氨基苯基)
-17β-羟基-17α-(3-羟基丙基)-4,9(10)-雌二烯-3-酮(C)和EP84730147.0所述的11β-(4-二甲基氨基苯基)-17β-羟基-17α-(3-羟基丙烯-1(Z)-基)-4,9(10)-雌二烯-3-酮(D)进行比较而体现出来。

从表中可以看出,使用本发明化合物(A)时只需0.3mg的剂量即可非常有效地进行流产,也就是说要比现有技术中的化合物有效3~10倍。
为了说明抗糖皮质激素功效,检测了本发明药物对酪氨酸-氨基转移酶(TAT)的作用。这一试验体系以测定RHC细胞(Rat Hepatoma Cells)培养基上肝酶酪氨酸氨基转移酶(TAT)的活性为基础的。这种酶对酸氨酸的初始代谢阶段起催化作用,不仅在肝中而且在肝细胞瘤中都可由糖皮激素诱发。活性在粗浸出物中很容易测得(Granner和Tomkins,(1970)Meth.Enzymol.15,633)。这种酶可将酪氨酸的氨基转移到2-氧代-戊二酸上,从而形成谷氨酸和对羟基苯基丙酮酸盐。用对羟基苯基丙酮酸盐可在碱性溶液中生成更稳定的对羟基苯甲醛,于331nm处测得其吸收峰。RHC细胞里的TAT活性在用可的索(在10-6M时有最大活性)或地塞米松(在10-7M时有最大活性)时显示出有赖于剂量的诱导。这一活性的刺激效果要基数值高出4~6位。同时用皮质激素和抗糖皮质激素进行治疗直至TAT活性下降。
本发明化合物(A)在这一试验中显示出的活性为作为标准进行观察的药物RU38.486(B)的2%(7th lnt.Congress of Endocrinology July 1-7,1984,Quebec City,Canada;Excerpta Mdeica,Amsterdan-OXford-Princeton)。
由于化合物(A)的抗孕激素效果比(B)强10倍,因此其抗糖皮激素效力和抗孕激素效力可以很明显地区分开。
本发明化合物的更突出的特征是与现有技术中的化合物比具有更高的代谢稳定性。
因此本发明还涉及以制药学上容许的即在应用剂型下无毒的通式Ⅰ化合物,且必要时还有常见的助剂和赋形剂为基础制成的药剂。
本发明化合物可按已知的盖伦制药方法制成肠内,经皮,胃肠外或局部服用的制剂,且可制成片剂,糖衣丸,胶囊,粒剂,栓剂,植入体,可注射的无菌水或油溶液,悬浮液或乳液,软膏,乳膏剂和凝胶。
可将活性物质与盖伦制药方法中常用的助剂如阿拉伯胶,滑石粉,淀粉,甘露糖,甲基纤维素,乳糖,表面活性剂如Tweens(R)或Myrj(R),硬酯酸镁,水性或非水性载体石蜡衍生物,润湿剂,分散剂,乳化剂,保藏剂和正味的芳香物质(例如醚香油)。
因此,本发明还涉及含有至少一种本发明化合物作活性物质的药物组合物。
每剂量单位中含约1~100mg活性物质,本发明化合物用量为每人每天约1~1000mg。
