– Talaromyketide B is a polyketide compound identified in the soil bacterium Talaromyces sp. KYS-41, known for its anti-inflammatory properties. It inhibits the activation of NF-κB and MAPK signaling pathways and can dose-dependently suppress pro-inflammatory cytokines, such as IL-1β, IL-6, IL-10, and TNF-α, as well as the transcriptional activity of inflammatory mediators [including iNOS and COX-2]. Talaromyketide B shows promise for research in the fields of immunity and inflammatory diseases.
