Target:  

SARS-CoV DNA/RNA Synthesis

Research Areas:  

Infection

K22 is an anti-Coronaviral compound. K22 reduces double-stranded RNA. K22 displays antiviral activity beyond the Coronavirinae subfamily, namely against nidoviruses of the Torovirinae subfamily (EToV and WBV) and members of the Arteriviridae family (PRRSV, EAV). K22 displays antiviral activity against HCoV-229E .

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.
