White to off-white powder. Soluble in DMSO or chloroform. Chemical. CAS: 148497-11-4. Formula: C9H15NO3. MW: 185.2. Synthetic. N-Pentanoyl-L-homoserine lactone is a small diffusible signaling molecule and is a member of N-acyl-homoserine lactone family. N-acylhomoserine lactones (AHL) are involved in quorum sensing, controlling gene expression, and cellular metabolism. This regulatory process manifests itself with a variety of phenotypes including biofilm formation and virulence factor production. Regulation of bacterial quorum sensing signaling systems to inhibit pathogenesis represents a new approach to antimicrobial therapy in the treatment of infectious diseases.
