本發(fā)明涉及化學(xué)技術(shù)領(lǐng)域,尤其是一種含二氟甲基的螺[環(huán)丙烷-1,3'-吲哚啉]-2'-酮類化合物和藥物用途。
背景技術(shù):
螺環(huán)氧化吲哚結(jié)構(gòu)單元廣泛存在于許多天然分子和臨床藥物分子中,在已發(fā)現(xiàn)的含有3,3'-螺環(huán)結(jié)構(gòu)的氧化吲哚類化合物中,很多都具有較高的生物活性,諸如抗腫瘤、抗病毒、抗hiv、抗氧化性等。其中,含有氧化吲哚螺環(huán)環(huán)丙烷結(jié)構(gòu)單元的分子更加引人注目,由于該類化合物可以作為黃體酮受體拮抗劑、rsv抑制劑、激酶抑制劑、抗腫瘤藥物等。
在另一方面,二氟甲基(-cf2h),作為一個(gè)重要的含氟基團(tuán),含有一個(gè)弱酸化的c-h鍵,是羥基、巰基及羥甲基的電子等排體,能夠調(diào)節(jié)分子的生物活性、代謝穩(wěn)定性以及親脂性等,在醫(yī)藥、農(nóng)藥等領(lǐng)域起著與其他氟烷基同樣重要的作用。因此,在分子中引入二氟甲基可賦予其諸多優(yōu)良性能,同時(shí)引入或保持了生物靶點(diǎn)的關(guān)鍵識(shí)別元素。這些決定了其在生物醫(yī)藥、生物成像等領(lǐng)域的巨大潛力和科研價(jià)值。
鑒于氧化吲哚螺環(huán)環(huán)丙烷化合物具有潛在的生物活性以及二氟甲基在藥物化學(xué)中的重要作用,因此,以二氟甲基重氮甲烷為砌塊,通過[3+2]反應(yīng)和縮環(huán)反應(yīng)策略與3-烯基氧化吲哚反應(yīng),合成含有二氟甲基基團(tuán)的3,3'-氧化吲哚螺環(huán)環(huán)丙烷可能會(huì)產(chǎn)生一系列結(jié)構(gòu)和活性上有意義的新化合物,它們的合成可以為含二氟甲基的螺[環(huán)丙烷-1,3'-吲哚啉]-2'-酮類化合物在藥物發(fā)現(xiàn)和成藥性評(píng)價(jià)中的應(yīng)用建立物質(zhì)基礎(chǔ)。
技術(shù)實(shí)現(xiàn)要素:
本發(fā)明的目的在于提供一種含二氟甲基的螺[環(huán)丙烷-1,3'-吲哚啉]-2'-酮類化合物及其制備防治腫瘤疾病藥物的應(yīng)用,該類化合物是一類重要的藥物活性分子,對(duì)藥物篩選和制藥行業(yè)具有重要的應(yīng)用價(jià)值,并且該類分子的合成具有反應(yīng)條件溫和、操作簡(jiǎn)單、底物普適性好的優(yōu)點(diǎn)。
本發(fā)明是這樣實(shí)現(xiàn)的:原位生成的二氟甲基重氮甲烷與靛紅衍生的3-烯基氧化吲哚在無催化劑條件下,在有機(jī)溶劑中進(jìn)行[3+2]反應(yīng)和縮環(huán)反應(yīng),獲得含二氟甲基的螺[環(huán)丙烷-1,3'-吲哚啉]-2'-酮類化合物。該類化合物具有如通式(ⅰ)所示的結(jié)構(gòu):
式中,r1為烷基、烷氧基或鹵素,r2為烷基,r3為烷基、芳基或?;?。
所述的有機(jī)溶劑為二氯甲烷、三氯甲烷、四氯化碳、乙腈、四氫呋喃、苯、甲苯、二甲苯、均三甲苯、1,4-二氧六環(huán)、乙二醇二甲醚、乙二醇二乙醚或甲基叔丁基醚。
原位生成的二氟甲基重氮甲烷與靛紅衍生的3-烯基氧化吲哚的反應(yīng)溫度為25-130℃,反應(yīng)時(shí)間為1-50小時(shí)。
所述的含二氟甲基的螺[環(huán)丙烷-1,3'-吲哚啉]-2'-酮類化合物在制備防治腫瘤疾病藥物的應(yīng)用。
本發(fā)明的反應(yīng)原理如下:
其中,r1,r2,r3和有機(jī)溶劑如上所述。
通過采用上述技術(shù)方案,二氟乙胺(1)放置于反應(yīng)瓶中,依次加入有機(jī)溶劑、亞硝酸叔丁酯和乙酸,并在70℃條件下反應(yīng)10分鐘,停止加熱,即可原位得到二氟甲基重氮甲烷(2)。然后將靛紅衍生的3-烯基氧化吲哚(3)加入反應(yīng)瓶中,經(jīng)過[3+2]反應(yīng)和縮環(huán)反應(yīng),合成了一系列含二氟甲基的螺[環(huán)丙烷-1,3'-吲哚啉]-2'-酮類化合物(4)。該類化合物含有潛在生物活性的二氟甲基基團(tuán)和3,3'-氧化吲哚螺環(huán)環(huán)丙烷骨架,可以為藥物發(fā)現(xiàn)和成藥性評(píng)價(jià)建立物質(zhì)基礎(chǔ),具有重要的應(yīng)用價(jià)值。本發(fā)明原料易于獲得,可以在各種有機(jī)溶劑中進(jìn)行,具有反應(yīng)條件溫和、操作簡(jiǎn)單、底物普適性好的優(yōu)點(diǎn)。
