A set of four new benzo[a]phenoxazinium chlorides possessing ethyl, propyl, decyl and tetradecyl groups at the 9-amino function of the heterocycle along with a propyl group at the 5-amino position was efficiently synthesized. These compounds displayed fluorescence with maximum emission wavelengths of 673 and 685 nm, in anhydrous ethanol and water. All the benzo[a]phenoxazines were evaluated against
有效地合成了一组四个新的苯并[ a ]苯恶嗪氯化物,它们在杂环的9-氨基官能团上具有乙基,丙基,癸基和十四烷基以及在5-氨基位置上具有丙基。这些化合物在无水乙醇和水中显示出最大发射波长为673和685 nm的荧光。在肉汤微量稀释试验中,针对酵母酵母对所有苯并[ a ]吩恶嗪进行了评估。发现它们的抗真菌活性取决于脂族链长度的变化。化合物7的最高MIC活性为1.56μM 包括在杂环核心的9-氨基位置上的二烷基化丙基取代基和在5-氨基位置上的丙基链。
