菲并吲哚(或喹喏)里西啶生物碱衍生物以及它们的制备和抗植物病毒活性应用
技术领域
本发明涉及13a取代的菲并吲哚里西啶和14a取代的菲并喹喏里西啶生物碱衍生物以及它们的制备和抗植物病毒活性应用。
背景技术
自1935年首个菲并吲哚里西啶生物碱-娃儿藤碱((R)-tylophorine)(1a)被分离以来,由于其独特的化学结构和显著的生物活性吸引了无数植物学家、合成化学家和药物学家的广泛关注。迄今为止,已经有近100种菲并吲哚里西啶生物碱被报道,它们主要存在于萝藦科(Asclepiadaceae)、桑科(Moraceae)、爵床科(Acanthaceae)和樟科(Lauraceae)植物中。在已被分离出的近百种菲并吲哚里西啶生物碱和菲并喹喏里西啶生物碱中,13a-氢菲并吲哚里西啶生物碱(如:(R)-tylophorine(1a)和(R)-antofine(1b))最为常见。1984年,两种结构新颖的菲并吲哚里西啶生物碱hypoestestatin 1(2a)和hypoestestatin 2(2b)被报道,它们的显著特征是在碳13a的位置都含有角甲基。同时发现hypoestestatin 1(2a)和hypoestestatin 2(2b)都具有特别显著的细胞毒性(对小鼠P-388细胞的ED50低达10-5μg/mL)。在随后几年,另外几种13a-甲基菲并吲哚里西啶生物碱(3a,3b,3c和4)被相继报道。虽然对13a-氢菲并吲哚里西啶和14a-氢菲并喹喏里西啶生物碱研究较多,但对13a非氢取代的菲并吲哚里西啶生物碱和14a非氢取代的菲并喹喏里西啶生物碱衍生物的研究却非常少。

上述优选化合物与已知化合物相比具有突出优点,具体表现在:(1)化学稳定性明显增强,同等条件下室温放置或者日光照射同等时间,变质速度明显比对照样品(R)-tylophorine慢很多。(2)光学稳定性明显增强,同等条件下室温放置或者日光照射同等时间,样品消旋速度明显比对照样品(R)-tylophorine慢很多。上述两点对化合物在农药上的应用具有至关重要的作用。
实施例7:抗烟草花叶病毒活性的测定,测定程序如下:
1、病毒提纯及浓度测定:
病毒提纯及浓度测定参照南开大学元素所生测室编制烟草花叶病毒SOP规范执行。病毒粗提液经2次聚乙二醇离心处理后,测定浓度,4℃冷藏备用。
2、化合物溶液配制:
称量后,原药加入DMF溶解,制得1×105μg/mL母液,后用含1‰吐温80水溶液稀释至所需浓度;宁南霉素制剂直接兑水稀释。
3、离体作用: 
摩擦接种珊西烟适龄叶片,用流水冲洗,病毒浓度10μg/mL。收干后剪下,沿叶中脉对剖,左右半叶分别浸于1‰吐温水及药剂中,30min后取出,于适宜光照温度下保湿培养,每3片叶为1次重复,重复3次。3d后记录病斑数,计算防效。
4、活体保护作用:
选长势均匀一致的3-5叶期珊西烟,全株喷雾施药,每处理3次重复,并设1‰吐温80水溶液对照。24h后,叶面撒布金刚砂(500目),用毛笔蘸取病毒液,在全叶面沿支脉方向轻擦2次,叶片下方用手掌支撑,病毒浓度10μg/mL,接种后用流水冲洗。3d后记录病斑数,计算防效。
5、活体治疗作用:
选长势均匀一致的3-5叶期珊西烟,用毛笔全叶接种病毒,病毒浓度为10μg/mL,接种后用流水冲洗。叶面收干后,全株喷雾施药,每处理3次重复,并设1‰吐温80水溶液对照。3d后记录病斑数,计算防效。
6、活体钝化作用:
选长势均匀一致的3-5叶期珊西烟,将药剂与等体积的病毒汁液混合钝化30min后,摩擦接种,病毒浓度20μg/mL,接种后即用流水冲洗,重复3次,设1‰吐温80水溶液对照。3d后数病斑数,计算结果。
抑制率(%)=[(对照枯斑数-处理枯斑数)/对照枯斑数]×100%
表1部分13a-取代的菲并里西啶和14a-取代的菲并喹喏里西啶生物碱衍生物(I)的抗TMV活性测试结果:
