Metabolite Identification
Common NameDahliane D
DescriptionDahliane D is a secondary metabolite belonging to the chemical class of radianspenes. Its chemical structure is characterized by unique carbon skeletons typical of this class, which contributes to its bioactivity. Dahliane D, along with radianspenes C and D, was isolated from the crude extract of Nemania sp., demonstrating its potential as a bioactive compound (PMID:36160406 ). In cellular assays, dahliane D has been shown to suppress the expression of mRNA encoding programmed death-ligand 1 (PD-L1) and the aromatic hydrocarbon receptor (AhR), as well as the surface expression of PD-L1 protein in cells exposed to benzo[a]pyrene (PMID:36160406 ). Furthermore, it reduces the expression of AhR, PD-L1, inducible T-cell costimulator ligand (ICOSL), and glucocorticoid-induced TNFR-related protein ligand (GITRL) proteins in H1975 lung cancer cells, while also exerting anti-proliferative effects (PMID:36160406 ). These pathways indicate dahliane D's involvement in modulating immune checkpoint proteins and cellular proliferation, highlighting its potential role in cancer biology.
