1,2-Benzisothiazol-3(2H)-one (BIT) is one of the most common chemical biocides in industrial products, with a heterocyclic structure and a wide range of antimicrobial activity. A library of BIT derivatives was synthesized and characterized, from which 18 compounds were selected, tested for anti-bacterial activity relative to the parent molecule and amenable of coupling to plant polysaccharides in general
1,2-苯并异噻唑-3(2H)-一(BIT)是工业产品中最常见的化学杀菌剂之一,具有杂环结构和广泛的抗菌活性。合成并表征了BIT衍生物的文库,从中选择了18种化合物,测试了相对于母体分子的抗菌活性,并适于与一般植物多糖,尤其是半乳甘露聚糖(GM)偶联,广泛用作流变学修饰剂,但“生物稳定性”有限。靶向BIT核心上的四个位点:杂环上的氮和氧原子,芳环上的C5和C6位置,引入了官能团。这项工作的最终目的是确定是否通过将杀生物剂与GM聚合物共价连接,可以提高其“生物稳定性”。
