为探寻更优异抑真菌活性的新颖化合物,在保留原有活性基团的基础上,通过药效团拼合策略,设计合成了同时含有噻吩和三氮唑杂环取代的1,5-苯并硫氮杂䓬Ⅱ'a~Ⅱ'e.在合成系列1,5-苯并硫氮杂䓬化合物VIa~VIe时,意外得到了2-噻吩亚甲基取代的新型1,5-苯并硫氮杂䓬Ⅶa~Ⅶe,提出了Ⅶa~Ⅶe生成的可能历程.测试了目标物Ⅱ'a~Ⅱ'e和Ⅶa~Ⅶe的抑真菌活性:Ⅱ'a~Ⅱ'e对新生隐球菌和白色念珠菌有中度的抑制作用,Ⅶa~Ⅶe有轻到中度的抑制作用,其中Ⅱ'a和Ⅶb对白色念珠菌展现出相对更优的活性,这一发现为抗真菌药物的结构优化提供了初步线索.

In order to find novel compounds with superior antifungal activity, a series of 1,5-benzothiazepines II'a~II'e containing both thiophene and triazole heterocyclic substitutions were designed and synthesized while retaining the original active groups by a pharmacophore hybridization strategy. During the synthesis of the 1,5-benzothiazepines VIa~VIe, a novel 1,5-benzothiazepines VIIa~VIIe with 2-thiophene methylene substitution were unexpectedly obtained, and a possible mechanism for the formation of VIIa~VIIe was proposed. The antifungal activities of II'a~II'e and VIIa~VIIe were tested: II'a~II'e showed moderate inhibitory effects on C. neoformans and C. albicans, while VIIa~VIIe showed mild to moderate inhibitory effects. Among them, II'a and VIIb exhibited relatively better activity against C. albicans, providing preliminary clues for the structural optimization of antifungal drugs.
