在这项工作中,使用苯二甲醛,甲胺,甲基丙二酰氯,烷基溴化物和三苯基膦的多组分反应,以优异的产率合成了吡啶并[2,1- a ]异喹啉和吡啶并[1,2- a ]喹啉。研究了氢氧化钠水溶液在80°C时催化的Fe 3 O 4 -MNPs的催化量。用三叶草叶水提取物还原氯化铁溶液导致了绿色方法的合成磁性氧化铁纳米颗粒(Fe 3 O 4 -MNPs)。同时,还研究了一些新合成的化合物如6a,6c,9b的抗氧化活性和9c使用DPPH自由基捕获和还原铁离子的实验,并将结果与合成抗氧化剂(TBHQ和BHT)进行了比较。结果,化合物6a,6c,9b和9c显示出良好的DPPH自由基捕获和优异的三价铁离子还原强度。
The purpose of the present invention is to provide a novel compound which has an anti-fungal activity on pathogenic fungi including fungi belonging to the genus
Candida
, the genus
Aspergillus
and the genus
Trichophyton
and is useful as a medicinal agent. A compound represented by formula (I) (wherein A
1
represents a nitrogen atom or a group represented by formula CR
6
; A
2
and A
3
are the same as or different from each other and independently represent a nitrogen atom or a group represented by formula CH; R
1
represents an aryl group which may be substituted by 1 to 5 substituents independently selected from a substituent group (2) or the like; R
2
and R
3
are the same as or different from each other and independently represent a hydrogen atom, a halogen atom, a C
1-6
alkyl group, a C
1-6
haloalkyl group or a C
1-6
alkoxy group; and R
4
and R
5
are the same as or different from each other and independently represent a hydrogen atom, a C
1-6
haloalkyl group, a C
1-6
alkyl group or the like) or a salt thereof is useful as an anti-fungal agent.
