技术领域
本发明涉及螺环氧化吲哚乙内酰(硫)脲衍生物及其制备方法和在防治植物病毒、杀菌、杀虫方面的应用,属农药技术领域。
背景技术
螺环氧化吲哚骨架结构广泛存在于天然产物和药物分子中。螺环氧化吲哚生物碱具有广泛的生物活性,例如:(-)-Horsfiline是从风吹楠属植物Hors fieldia superba中分离得到的螺环氧化吲哚类生物碱,该生物碱具有明显的镇痛效果;Spirotryprostatin A是从烟曲霉菌 Aspergillus fumigatus中分离得到的,它可以抑制哺乳动物tsFT210细胞的G2M周期的进行,进而抑制该细胞的增殖;Strychnofoline是从马钱属植物Strychnosusambarensis的叶片中分离得到的,该生物碱对老鼠的黑色素瘤细胞和Ehrlich肿瘤细胞的有丝分裂过程具有抑制作用。
目前,对于螺环氧化吲哚类化合物的研究主要集中在治疗Alzheimer病和抗肿瘤等医药领域。据我们所知,对于螺环氧化吲哚类化合物的抗植物病毒活性、杀菌活性和杀虫活性等农药领域的研究没有文献报道。在治疗Alzheimer病方面:2012年辉瑞公司的Efremov Ivan V. 和Vajdos Felix F.设计合成了含有螺环氧化吲哚-5′-甲酰酯的衍生物,发现该类化合物对天冬氨酰蛋白酶具有明显的抑制剂作用,其IC50值为1uM,可以用作治疗Alzheimer病的药物 (Efremov,Ivan V.;Vajdos,Felix F.;Borzilleri,Kris A.etal.J.Med.Chem.,2012,55, 9069-9088.)。在抗肿瘤方面:2008年Gilchrest Barbara A等设计了含有螺环氧化吲哚-5′-甲酸酯类衍生物,发现此类衍生物可以诱导细胞凋亡,同时对人类黑色素瘤细胞蛋白激酶ATM具有激活作用(Gilchrest,Barbara A.;Eller,Mark S.;Koehler,Angela N.et al.WO 2008027990 A1);2008年Lewis Timothy A.等设计了含有螺环氧化吲哚-5′-甲酸酯类衍生物,发现此类衍生物对细胞增殖必要的一种丝氨酸/苏氨酸激酶aurora激酶具有明显的抑制作用,进而可以抑制肿瘤细胞的增殖(Lewis,Timothy A.;Munger,Karl;Howley,Peter M.et al.WO 2008144507 A2);2011年Wang Shaomeng等设计了含有螺环氧化吲哚-5′-甲酰胺结构的衍生物,发现该类化合物对小鼠接种的SJSA-1肿瘤细胞具有明显的抑制其增殖的作用(Wang,Shaomeng;Yu, Shanghai;Sun,Wei et al.US20110112052 A1.)。
