Based on the C(3)-1,2,4-triazole substituted 1,5-benzothiazines discovered in the previous report, C(2)-1,2,4-tria- zole substituted 1,5-benzothiazines Ⅳa~Ⅳf were designed and synthesized by the strategy of changing the position of the pharmacophore in the molecular skeleton of the lead compound. Quinoline derivatives Ⅴa~Ⅴf were obtained accidentally during the synthesis of 1,5-benzothiazepines Ⅳ'a~Ⅳ'f containing 1,2,4-triazole at both C(2) and C(3), and the possible mechanism of Ⅴa~Ⅴf formation was studied. The antimicrobial activity of the target compounds Ⅳa~Ⅳf and Ⅴa~Ⅴf was tested, Ⅳa~Ⅳf showed moderate to high inhibitory effects on C. neoformans, C. albicansa and S. aureus, while Ⅴa~Ⅴf had mild to moderate inhibitory effects. The inhibitory effect of Ⅳa on C. neoformans and C. albicans was higher than that of control drug fluconazole. This result had certain reference value for the development of antifungal drugs.
