ABSTRACT In the present study, 20 new tetracyclic 1,4-benzothiazines (4a–4 t) were conveniently synthesized in good yields and characterized by different spectral and physical techniques. The in vitro antimicrobial evaluation of the synthesized benzothiazine derivatives was performed by serial dilution against two Gram-positive bacteria [Bacillus subtilis (MTCC 441) and Staphylococcus epidermidis (MTCC
摘要 在本研究中,20 种新的四环 1,4-苯并噻嗪 (4a-4 t) 以良好的收率方便地合成,并通过不同的光谱和物理技术进行表征。通过对两种革兰氏阳性菌 [枯草芽孢杆菌 (MTCC 441) 和表皮葡萄球菌 (MTCC 6880)]、两种革兰氏阴性菌 [大肠杆菌 (MTCC 1652) 和铜绿假单胞菌 (MTCC 424)] 和两种真菌菌株 [白色念珠菌 (MTCC 227) 和黑曲霉 (MTCC 8189)]。发现衍生物 4 l 和 4 t 分别比标准药物(即氟康唑)更有效地对抗黑曲霉和白色念珠菌。图形概要
