HY-W127487

N-Octadecanoyl-L-homoserine lactone	Biochemical Assay Reagents	Others
Quorum sensing is a regulatory system used by bacteria to control gene expression in response to increased cell density. This regulatory process manifests itself in a variety of phenotypes, including biofilm formation and virulence factor production. Coordinated gene expression is achieved through the production, release and detection of small diffusible signaling molecules called autoinducers. N-acylated homoserine lactones (AHLs) comprise a class of such autoinducers, each of which generally consists of a fatty acid coupled to a homoserine lactone (HSL). Modulation of bacterial quorum-sensing signaling systems to suppress pathogenesis represents a new approach to antimicrobial research for infectious diseases. AHLs differ in acyl length (C4-C18), C3 substitution (hydrogen, hydroxyl, or oxo group), and the presence or absence of one or more carbon-carbon double bonds in the fatty acid chain. These differences confer signaling specificity through the affinity of the LuxR family of transcriptional regulators. C18-HSL, one of four lipophilic long acyl side chain AHLs produced by the LuxI AHL synthase homolog SinI, is involved in quorum-sensing signaling in strains of Rhizobium meliloti (a nitrogen-fixing bacterial symbiont of the legume M. sativa) . C18-HSL and other hydrophobic AHLs tend to localize in the relatively lipophilic environment of bacterial cells and cannot diffuse freely across the cell membrane. Long-chain N-acyl homoserine lactones can be exported from cells by efflux pumps, or can be transported between communicating cells by extracellular outer membrane vesicles.

Autophagy Compound Library	1,631 compounds
Autophagy is a lysosomal degradation pathway that is essential for cell survival, differentiation, development, and homeostasis. The process of autophagy in mammalian cells is as follows: a portion of cytoplasm, including organelles, is enclosed by a phagophore or isolation membrane to form an autophagosome. The outer membrane of the autophagosome subsequently fuses with the endosome and then the lysosome, and the internal material is degraded. Autophagy plays a wide variety of physiological and pathophysiological roles. Defective autophagy contributes to various pathologies, including infections, cancer, neurodegeneration, aging, and heart disease. MCE provides a unique collection of 1,631 autophagy pathway-related compounds that is a useful tool for the research of autophagy-related regulation and diseases.

HY-L144

Mitochondrial Protection Compound Library	902 compounds
Normal mitochondrial function is critical for maintaining cellular homeostasis because mitochondria produce ATP and are the major intracellular source of free radicals. Cellular dysfunctions induced by intracellular or extracellular insults converge on mitochondria and induce a sudden increase in permeability on the inner mitochondrial membrane, the so-called mitochondrial membrane permeability transition (MMPT). MMPT is caused by the opening of pores in the inner mitochondrial membrane, matrix swelling, and outer membrane rupture. The MMPT is an endpoint to initiate cell death because the pore opening together with the release of mitochondrial cytochrome c activates the apoptotic pathway of caspases. The normal operation of mitochondrial function is important for maintaining normal cell death and treatment of mitochondrial diseases. MCE offers a unique collection of 902 compounds with identified and potential mitochondrial protective activity. MCE Mitochondrial Protection Compound Library is critical for drug discovery and development.
