Background:

Tropolone is a terpene that has been found in cupressaceous tree bark and has diverse biological activities.1,2,3,4,5 It inhibits catechol O-methyltransferase (COMT; Ki = 22 μM).1 Tropolone is bacteriostatic against a panel of Gram-positive and Gram-negative bacteria (MICs = 12-82 μM) and bactericidal against A. hydrophilia and C. violaceum when used at a concentration of 20 mM.2 It is an iron chelator that inhibits iron-dependent growth of the wood rot fungus P. placenta when used at a concentration of 50 μM and P. placenta degradation of pine sapwood blocks impregnated with 5 mM tropolone.3 It inhibits LPS-induced production of nitric oxide (NO) in RAW 264.7 cells (IC50 = 12 μM).4 Tropolone (0.25 mmol/animal) reduces thyroid radioiodide uptake in rats.5 Dietary administration of tropolone induces growth retardation and hyperactivity in mice.
