N-alpha-haloacylated homoserine lactones, in which a halogen atom was introduced at the alpha-position of the carbonyl function of the N-acyl chain, have been studied as quorum sensing (QS) modulators and compared with a library of natural N-acylated homoserine lactones (AHLs). The series of novel analogues consists of alpha-chloro, alpha-bromo and alpha-iodo AHL analogues. Furthermore, the biological QS activity of
已经研究了新型N-α-卤代高丝氨酸内酯,其中在N-酰基链的羰基官能团的α-位置引入了卤素原子,作为群体感应(QS)调节剂,并与天然N库进行了比较酰化的高丝氨酸内酯(AHL)。该系列新的类似物由α-氯,α-溴和α-碘的AHL类似物组成。此外,评估了与天然AHL相比,合成AHL类似物的生物学QS活性。卤代类似物在大肠杆菌JB523生物测定中显示出降低的活性,其中α-碘内酯的活性较低,而α-氯代AHL的效力最强。当在QS抑制测试中进行测试时,大多数α-卤代酰化类似物没有表现出明显的减少。所以,
