An antibiotic used to treat a number of bacterial infections that acts by inhibiting proper cell wall synthesis.

57-dihydroxy-4-phenyl coumarin is found in the plant Passiflora serratodigitata with the antibacterial activity.

TLR2/6 agonist (also a putative TLR10 ligand). Activates NF-κB. Induces pro-inflammatory cytokines including IL-8, IL-1β, CCL20 and TNF-α in vitro. Synergizes with IFNγ to induce CXCL10 release from melanoma cells.
