N-acylhomoserine lactone (AHL) analogues in which the amide function is replaced by a reverse-amide one have been studied as AHL QS modulators. The series of compounds consists of α-(N-alkyl-carboxamide)-γ-butyrolactones, α-(N-alkyl-sulfonamide)-γ-butyrolactones, and 2-(N-alkyl-carboxamide)-cyclopentanones and cyclopentanols. Most active compounds exhibited antagonist activities against LuxR reaching
已经研究了新的N-酰基高丝氨酸内酯(AHL)类似物,其中酰胺功能被一种反向酰胺取代,作为AHL QS调节剂。该系列化合物由α-(N-烷基-羧酰胺)-γ-丁内酯,α-(N-烷基-磺酰胺)-γ-丁内酯和2-(N-烷基-羧酰胺)-环戊酮和环戊醇组成。大多数活性化合物对LuxR的拮抗活性均达到30μM。
