Popis: | Four series of ring substituted ( E )-3-phenyl-1-(2-pyrazinyl)-2-propen-1-ones were prepared by means of modified Claisen–Schmidt condensation of acetylpyrazines with aromatic aldehydes. The structures were confirmed by elemental analysis, IR, 1 H NMR and 13 C NMR spectra. The compounds were tested for specific biological properties and some derivatives exhibited photosynthesis-inhibiting, antifungal and antimycobacterial properties. The most pronounced effects were observed with compounds substituted with phenolic groups. Ortho -hydroxyl substituted derivatives were more potent than the corresponding para -hydroxyl substituted analogues. |
