has more recently been characterized as a bacterial chalkophore and potential virulence factor. Herein, we report a modular synthesis of SF2768 and related acyclic analogues, allowing assignment of syn-stereochemistry across the central lactol ring. The copper-binding properties of these diisonitriles have also been studied.
Chalkophores是细菌的天然产物,可螯合和转运细胞外铜。二异腈腈天然产物SF2768首先作为抗真菌抗生素从链霉菌属物种中分离出来,最近被表征为细菌生粉团和潜在的致病因子。在这里,我们报告SF2768和相关的无环类似物的模块合成,允许整个中央乳醇环的顺式立体化学的分配。还已经研究了这些二腈的铜结合性能。
