Let’s face it, organic chemistry can seem difficult to learn, Recommanded Product: 1,4-Dibromonaphthalene, Especially from a beginner’s point of view. Like 83-53-4, Name is 1,4-Dibromonaphthalene, molecular formula is phthalazine, belongs to phthalazine compound. In a document, author is Cui, Zhi-Ming, introducing its new discovery.
Inspired by sanguinarine and chelerythrine, a novel antifungal 2-phenylphthalazin-2-ium scaffold as a simple analogue was designed. Most of the 30 compounds showed excellent inhibition activity against almost all eight phytopathogenic fungi, far superior to sanguinarine and chelerythrine. A third of the compounds were more active than azoxystrobin in most cases. Compounds 26 and 27 showed the highest total activity against all the fungi with EC50 means of ca. 4.6 mu g/mL. Fusarium solani showed the highest susceptibility with an EC50 mean of 3.62 mu g/mL to 19 compounds. A concentration of 25.0 mu g/mL 27 can fully control the Colletotrichum gloeosporioides infection in apples over 9 days. Electron microscopic observations showed that 27 was able to damage the structures of the hypha and cell membrane. The structure-activity relationship showed that the presence of electron-withdrawing groups on the C-ring increases the activity against most of the fungi. Thus, 2-phenylphthalazin-2-ium compounds represent promising leads for the development of novel fungicides.
