Description

茉莉酮酸酯衍生物及其在植物细胞中的应用
技术领域
本发明涉及一类新型茉莉酮酸酯类化合物及其用途。
背景技术
自然界丰富的植物资源蕴涵着数量可观的次生代谢产物,其中包括许多昂贵的医药品。为了开发这些宝贵的资源,除了从植物原材料进行提取或有可能进行化学合成以外,植物细胞体外大规模培养技术也是一条有效之途径。利用诱导剂进行次生代谢产物调控已得到越来越多国内外学者的关注,并成为大幅度提高培养物中次生代谢产物含量的重要方法之一(谢秋玲,郭勇,食品科学,1998,19(10),7-9)。
紫杉醇是一类红豆杉属植物中含有的次生代谢产物,由于其独特的抗癌机理和疗效,目前被认为是癌症患者的首选药物。据估计,2000年紫杉醇的销售额达到16亿美圆(A.M.Thayer.Chem.Eng.News.,2000,78(45),20)。因此,各国科研人员对如何提高紫杉醇的产量进行了广泛的研究。由于红豆杉植物生长缓慢和分布狭窄,直接提取无法满足市场需要且对环境不利。虽然其全合成已经完成,但产率太低无法实现大量生产((1)R.A.Holton,C.Somoza,et al.,J.Am.Chem.Soc.,1994,116,1957,(2)K.C.Nicolaou,Z.Yang,et al.,Nature,1994,367,630)。目前,绝大部分紫杉醇和紫杉醇前体化合物都是利用各种红豆杉植物细胞在诱导剂作用下培养获得。
利用红豆杉植物细胞培养紫杉醇的诱导剂一般分两种,即生物和非生物诱导剂。生物诱导剂有细菌、真菌和酵母;非生物诱导剂有各种有机酸如水杨酸、2,4-D、花生四烯酸等,稀土金属盐类如硝酸铈、硝酸银等。到目前为止,诱导效果最好的是茉莉酮酸甲酯(MJA)。((1)Y Yukimune,H.Tabata,et al.,Nat.Biotechnol.,14(1996),110-118(2)R.E.B.Ketchum,D.M.Gibson,R.B.Croteau,M.L.Shuler,,Biotechnol.Bioeng.62,97-105,1999)。茉莉酮酸甲酯是首先从素馨花(Jasminium Gradiflrum)香精油中分离出的有气味的化合物,也是茉莉宁特殊香味的重要组分。它具有非常重要的生理功能,它有植物生长调节剂的作用,是近年来研究极为热门的一类芳香类化合物(宾金华,植物学通报,1995,12(4),17-21)。它还是一类很重要的植物信号传导分子,能激发植物的抗病反应(SAR-系统获得抗性)。在细胞培养中使细胞产生过敏反应,导致细胞的代谢途径和代谢通量发生变化,是性能优良的诱导剂。人们也曾对MJA的天然结构做过一些改变,试图找到性能更好的MJA衍生物,但现有的经修饰后的MJA衍生物的诱导性能均不理想(Otto Miersch,Robert Kramell,et al.,Phytochem.,50(1999),353-61)。
本发明选取中国红豆杉(T.chinensis)细胞作为应用体系,以MJA结构为先导,通过引入含氟、含羟基及一些植物生长调节剂前体,设计、合成一系列植物细胞诱导剂。实验结果表明:其中的几个化合物在促进紫杉烷的生物合成方面效果优于茉莉酮酸甲酯(MJA),具有相当的实用价值。
本发明所涉及的茉莉酮酸酯类化合物具有如下结构式:式中:R=SCH3,OCH2CF3,OCH2CF2CF3,OCH2C6F5或O(CH2CH2O)nR1;R1=H,

n=1,2或3;R2为烷基,羟基,卤素,芳烃或含氮杂环;R3为烷基,羟基,卤素,芳烃或含氮杂环。上述化合物的合成路线:
