Abstract In recent years, synthesis and biological evaluation of novel 4H-1,4-benzothiazines and their sulfone derivatives have gained momentum due to their medicinal and industrial importance. Our studies focused on the design and synthesis of new antimicrobial agents, and for this purpose a series of novel 4H-1,4-benzothiazines and their sulfone derivatives were synthesized and their in vitro antimicrobial
摘要 近年来,新型 4H-1,4-苯并噻嗪及其砜衍生物的合成和生物学评价因其药用和工业重要性而获得发展。我们的研究集中在新抗菌剂的设计和合成上,为此目的合成了一系列新型 4H-1,4-苯并噻嗪及其砜衍生物,并对具有代表性的革兰氏菌群进行了体外抗菌评估。阳性和革兰氏阴性细菌菌株和选定的真菌物种。报道的 4H-1,4-苯并噻嗪是通过缩合然后将取代的 2-氨基苯硫醇与含有活性亚甲基的化合物氧化环化来制备的。据信反应是通过烯氨基酮系统的中介进行的。砜衍生物是通过在冰醋酸中使用 30% 过氧化氢氧化 4H-1,4-苯并噻嗪来合成的。通过光谱和元素研究进行结构测定。
