Bacteria communicate using chemical signaling molecules as words. They release, detect, and respond to the accumulation of these molecules, which are called autoinducers. Detection of autoinducers allows bacteria to distinguish between low and high cell population density, and to control gene expression in response to changes the cell number. This process is termed quorum sensing. Many bacterial behaviors are regulated by quorum sensing, including virulence factors on gram negative bacteria. Quorum sensing is a novel target for antimicrobial therapies. Many eukariots including plants, fungus, and animals produce molecules that can interfered bacteria communication, such as halogen furanon from alga Delisea pulchra, N- (heptylsulfanylacetyl)-L-homoserine-lactone from Allium sativum, and flustramine from bryozoan Flustra foliacea.

Since their initial isolation from the marine alga Delisea pulchra, bromofuranones have been investigated as potential inhibitors of quorum sensing (QS) in various bacterial strains. QS is an important mechanism by which bacteria co-ordinate their molecular response to the environment. QS is intrinsically linked to bacterial antibiotic resistance. Inspired by nature, chemists have developed a wide variety of synthetic analogs in an effort to elucidate the structure–activity relationships of these compounds, and to ultimately develop novel antimicrobial agents. In this work, we describe advances in this field while paying particular attention to apparent structure–activity relationships. This review is organized according to the main ring systems under investigation, namely furanones, dihydropyrrolones and thiophenones.
