Description

丙酮酸脱氢酶系抑制剂类化合物及其制备方法和应用
技术领域
本发明涉及化学领域,具体的,本发明涉及化合物、制备方法及其应用,更具体的,本发明涉及式Ι所示化合物以及衍生物及其制备方法和应用。
背景技术
探索、发现不仅具有新结构,而且具有新靶标的农药活性化合物,是目前新农药创制研究关注的焦点。在生物的代谢过程中,丙酮酸脱氢酶复合体可以催化生物体内的丙酮酸转变成乙酰辅酶A,其是连接糖酵解与柠檬酸循环的关键酶,也是生物体内能量代谢过程的关键酶。因此,丙酮酸脱氢酶复合体是一个具有重要农学意义的作用靶标,针对此靶标进行农药分子的合理设计也具有很高的研究价值。目前已有一些丙酮酸脱氢酶系抑制剂的报道,例如,焦磷酸硫胺素类似物T-1与T-2,是针对微生物中丙酮酸脱氢酶系的高效抑制剂。
但该类化合物结构复杂,合成难度大,而且此类焦磷酸硫胺素类似物尚未显示出在农业方面的应用价值。因此,具有应用价值的丙酮酸脱氢酶系抑制剂类化合物仍有待研究发现。
发明内容
本发明旨在至少在一定程度上解决相关技术中的技术问题之一或至少提供一种有用的商业选择。为此,本发明的目的在于提出一类具有抑制丙酮酸脱氢酶活性、抗菌和抑藻活性的化合物。
在本发明的第一方面,提供了一种化合物。根据本发明的实施例,该化合物为式I所示丙酮酸脱氢酶系抑制剂类化合物或其立体异构体、几何异构体、互变异构体、消旋体、氮氧化物、水合物、溶剂化物、药学上可接受的盐,
其中,

R3为苯环任意位置上的单取代或多取代基,例如可以为对位或间位取代;所述取代基可以相同或不同;
X为酰腙基或腙基。
发明人惊奇地发现,本发明实施例的化合物具有有效抑制丙酮酸脱氢酶系的活性、抗菌和抑制藻类生长的生物活性。
根据本发明的实施例,上述化合物还可以具有下列附加技术特征:
根据本发明的实施例,所述取代基R1和R2可以自由排列组合。
根据本发明的实施例,所述取代基R1和R2各自独立的选自氢、C1-10烷基、氨基或3至5元的碳环基。
根据本发明的实施例,所述取代基R1为氢、甲基、氨基或环丙基。
根据本发明的实施例,所述取代基R2为氢或甲基。
根据本发明的实施例,所述取代基R3选自卤素、C1-10烷基、烷氧基、卤代烷基、卤代烷氧基、硝基、氨基、羟基。
根据本发明的实施例,所述取代基R3选自取代或未取代的苯甲酰胺基、烷基酰胺基、苯基脲基、呋喃酰胺基,例如所述取代可以为卤代或烷氧基取代,进一步的,所述卤代可以为1-2个卤素或卤代烷基取代。
根据本发明的实施例,所述卤素为氟、氯、溴、碘。
根据本发明的实施例,所述烷基酰胺基为C1-4烷基酰胺基。
根据本发明的实施例,所述取代基R3选自C1-4烷基。
根据本发明的实施例,所述烷氧基为C1-6烷氧基。
根据本发明的实施例,所述卤代烷基为氟代C1-4烷基。

根据本发明的具体实施例,所述化合物为下列化合物或者所述下列化合物的立体异构体、几何异构体、互变异构体、消旋体、氮氧化物、水合物、溶剂化物、药学上可接受的盐:
在本发明的第二方面,本发明提供了一种制备前面所述化合物的方法,根据本发明的实施例,该方法包括:
使式II所示化合物与式III所示化合物进行接触,以便获得式I所示化合物。
Y=-CONHNH2-或者-NHNH2-
其中R1、R2、R3、X具有上文所述的定义,Y为式III所示化合物的结构单元,具体可以为酰肼结构单元(-CONHNH2)或肼结构单元(-NHNH2)。
根据本发明的实施例,在催化剂存在下,将式II所示化合物与式III所示化合物溶于第一有机溶剂中,加热搅拌。
根据本发明的实施例,所述式II所示化合物与式III所示化合物以及催化剂的摩尔比为1:(1-1.5):(0.01-0.15)。在此条件下,可以使II所示化合物反应完全,后处理简单,从而以更高的产率获得目标化合物。
根据本发明的实施例,所述催化剂为选自抗坏血酸、乙酸、酒石酸、三氟乙酸、甲酸、水杨酸、苹果酸、乙酸酐中的至少一种。在使用催化剂的条件下,可以提升反应效率。

根据本发明的实施例,所述加热反应的温度为20~90摄氏度,优选为64~78摄氏度。由此可以提高反应速率,以较高产率获得目标化合物。如果反应温度过低,会导致反应不能发生或反应很慢,导致反应失败或产率很低。而反应最优的温度在64-78摄氏度之间,反应温度过高,则会提高反应成本,或增加副产物。
根据本发明的实施例,所述加热反应的时间为0.5~60小时,优选为3~48小时。由此可以保证反应物充分反应,以较高产率获得目标化合物。如果反应时间太短,反应不完全,不仅降低了产率,而且增加了后处理的难度。如果反应时间太长,超过了最优时间,对产率的影响不大,在相似的产率下,不仅提高了成本,而且浪费了时间。还可能增加副产物。

在本发明的第四方面,本发明提供了前面所述的化合物或农药预防和/或治疗植物疾病的方法,所述植物疾病是由下列至少之一引起的:水稻纹枯病菌,稻曲病菌,苹果轮纹,桃褐腐病菌,辣椒疫霉,灰霉病菌,炭疽病菌。根据本发明的实施例,所述植物为水稻,苹果,桃子或辣椒。

大肠杆菌丙酮酸脱氢酶抑制活性实验
试验材料:大肠杆菌丙酮酸脱氢酶
(1)本申请通过DCIP法测试代表性化合物对酶的抑制作用,由此来筛选高效的丙酮酸脱氢酶(PDHc-E1)抑制剂,初筛待测化合物的终浓度设定为100μM。具体筛选方法如下:
①配置95μL反应混合液:0.05μg/μL PDHc-E1,50mM K3PO4(pH=6.4),50μM ThDP,0.4mM DCIP,100μM用DMSO溶解的待测化合物(对照组加等量的DMSO),其余用水补齐(共配置4倍量的反应液于2mL的EP管中),放置在37℃水浴锅中温育3min。
②酶促反应:分别取95μL温育后的反应液加入到96孔酶标板的3个孔中,迅速加入5μL1mM的底物丙酮酸钠开启反应,置于酶标仪中测600nm处的吸光度值,反应0min时测定OD0min,37℃酶标仪中反应5min后,测定OD5min。然后求5min内的吸光度值改变量△OD600=OD0min-OD5min。每次测定均做溶剂DMSO的对照实验,每组实验做3~5个平行。
③数据处理:化合物引起的吸光度值的改变需扣除溶剂DMSO的影响,100μM待测化合物的抑制率的计算公式如下:
抑制率=[(△OD对照-△OD实验)/△OD对照]*100%
(2)化合物对大肠杆菌PDHc-E1抑制活性IC50的测定:
先用溶剂(DMSO)将待测化合物配制成一定梯度,在100μL测活体系中加入50μMThDP,0.4mM 2,6-DCIP,50mM K3P04(pH=6.4),5μg PDHc-E1(Cx-ace)和一定梯度的待测化合物2μl。先不加底物丙酮酸钠,在37℃的恒温箱中温育3min,让酶与待测化合物充分结合,然后加入50μM底物开启反应,用酶标仪测600nm处光吸收值,0min时测一次OD0min,在37℃的酶标仪再反应5min,再测OD5min,最后求吸光值的差值△OD600,每次实验均做化合物的溶剂DMSO的空白对照,每组实验做3~5个平行。分别测出每个化合物在梯度浓度下对酶的抑制率。在梯度浓度下测定每个化合物对酶的抑制率(需先扣除DMSO对酶活性的影响)以化合物浓度为横坐标,抑制率为纵坐标,用Orgin7.5软件中的Logistic函数作图,由函数拟合得出的X0即为IC50。其中Logistic函数公式为:y=[A1-A2/1+(x/x0)p]+A2
