群体感应(QS)是细菌调节细胞密度依赖性群体行为的一种机制。革兰氏阳性菌通常依赖于基于自诱导肽(AIP)的QS信号来调节其群体行为。为了开发这些行为的合成调节剂,需要鉴定天然肽,并且需要理解其与其同源受体(膜结合或胞质)的结构-活性关系(SAR)。SAR信息允许具有增强特征的肽或肽模拟物的合理设计,这反过来可以用于研究以了解物种特异性QS机制,并作为开发靶向QS的治疗候选物的主要支架。在这篇综述中,我们讨论了最近的工作与用于转发革兰氏阳性菌中的每一个步骤的方法,重点是那些受到较少关注的物种。本文综述了基于肽的群体感应调节剂的发展及其作为潜在治疗药物的应用。
Quorum sensing (QS) is a mechanism by which bacteria regulate cell density-dependent group behaviors. Gram-positive bacteria generally rely on auto-inducing peptide (AIP)-based QS signaling to regulate their group behaviors. To develop synthetic modulators of these behaviors, the natural peptide needs to be identified and its structure-activity relationships (SARs) with its cognate receptor (either membrane-bound or cytosolic) need to be understood. SAR information allows for the rational design of peptides or peptide mimics with enhanced characteristics, which in turn can be utilized in studies to understand species-specific QS mechanisms and as lead scaffolds for the development of therapeutic candidates that target QS. In this review, we discuss recent work associated with the approaches used towards forwarding each of these steps in Gram-positive bacteria, with a focus on species that have received less attention. This review discusses the development of peptide-based quorum sensing modulators and their use as potential therapeutics.
