Abstract
本发明涉及一种倍半萜laurene及其衍生物在治疗植物病毒病菌病中的应用,本发明首次发现倍半萜laurene及其衍生物I‑1~I‑19表现出很好的抗植物病毒病菌活性,能很好地抑制烟草花叶病毒(TMV)和黄瓜枯萎,花生褐斑,苹果轮纹,小麦纹枯,番茄早疫,水稻稻瘟,辣椒疫霉,油菜菌核8种植物病菌。
Description
技术领域
本发明涉及倍半萜laurene及其衍生物在治疗植物病毒和病菌病中的应用,属于农业防护技术领域。
背景技术
Laurene(反应式一)是一种含有1、2、3取代的环戊烯结构的倍半萜,主要存在于海洋红藻中,1965年日本北海道大学的Irie课题组(Tetrahedron Lett.1965,6,3619-3624.)首次从海洋红藻Laurencia glandulifera代谢物中分离出laurene。2012年,中国科学院烟台海岸带研究所的Ji课题组(Fitoterapia.2012,83,518-522.)从海洋红藻Laurenciaokamurai中分离出倍半萜laurene。
1973年,加利福尼亚大学的McMurry课题组以环己酮为原料,经11步反应实现了天然产物laurene的全合成(Tetrahedron.1974,30,2027-2032.),总收率为5.54%(反应式一),反应路线较长,总收率较低。1989年,印度班加罗尔科学研究所的Srikrishna课题组以1-(对甲苯基)丙-1-酮为起始原料通过自由基环化,经6步反应完成了天然产物(±)-laurene的全合成(Tetrahedron Lett.1989,30,3561-3562.),总收率为15.3%(反应式二)。1995年,康涅狄格大学的Bailey课题组通过有机锂的5-exo环化实现了五元环的构建,并通过该方案实现了天然产物laurene和epilaurene的合成(J.Org.Chem.1995,60,6511-6514.),反应经五步完成,总收率为38.7%(反应式三)。
倍半萜类化合物具有广泛的生物活性,laurene类化合物的详细生物学特性还有待研究,但其他类似的倍半萜类化合物,如铜烯(cuparenes)和赫伯烯(herbertenes)已被发现是有效的抗真菌、抗生素、神经营养和抗脂质过氧化药物。截至目前,还没有关于倍半萜防治植物病毒病菌病方面的报道。
发明内容
本发明提供倍半萜衍生物在防治植物病毒病菌病中的应用。本专利的倍半萜衍生物具有很好的抗植物病毒和病菌活性。
本发明的倍半萜衍生物为I-1~I-19。
相比于现有技术,本发明首次发现倍半萜衍生物I-1~I-19表现出很好的抗植物病毒和病菌活性,能很好地抑制烟草花叶病毒(TMV)和黄瓜枯萎,花生褐斑,苹果轮纹,小麦纹枯,番茄早疫,水稻稻瘟,辣椒疫霉,油菜菌核8种植物病菌。

实施例2: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;病毒唑制剂直接兑水稀释。
3、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。
4、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。
5、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‰0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%
首先在处理剂量500μg/mL条件下进行所有化合物的抗烟草花叶病毒活体钝化活性测试,相对抑制率大于40%的化合物进一步进行处理剂量500μg/mL条件下的活体治疗和活性保护活性测试以及处理剂量100μg/mL条件下的抗烟草花叶病毒活体钝化、活体治疗、活体保护活性测试。阳性对照为商品化抗植物病毒药剂病毒唑。
表1倍半萜laurene衍生物I-1~I-19的抗烟草花叶病毒(TMV)活性测试结果
从表一数据可见,倍半萜laurene衍生物I-1~I-19均表现出不错的抗TMV活性,其中在 500μg/mL情况下,有7种化合物的活性与病毒唑相当,具有极大的开发价值。
实施例3:抗菌活性测试,测定程序如下:
离体杀菌测试,菌体生长速率测定法(平皿法):
将一定量药剂溶解在适量丙酮内,然后用含有200μg/mL乳化剂水溶液稀释至所需浓度,然后各吸取1mL药液注入培养皿内,再分别加入9mL培养基,摇匀后制成50μg/mL的含药平板,以添加1mL灭菌水的平板做空白对照。用直径4mm的打孔器沿菌丝外缘切取菌盘,移至含药平板上。每处理重复三次。将培养皿放在24±1℃恒温培养箱内培养。48小时后调查各处理菌盘扩展直径,求平均值,与空白对照比较计算相对抑菌率。
表2倍半萜laurene衍生物I-1~I-19的离体杀菌活性测试结果:
倍半萜laurene衍生物在测试浓度为50μg/mL的条件下对8种被测试菌都表现出广谱的抑制活性。化合物I-10对水稻稻瘟抑制率到达80%。部分化合物对部分菌株抑制活性优于商品化品种百菌清,具备极大的开发价值。
