Reticulol is an isocoumarin derivative produced by certain species of Streptomyces that inhibits cAMP phosphodiesterase (IC50 = 41 μM). It also inhibits DNA topoisomerase I when used at a concentration of 45 μM in B16F10 melanoma cells. Reticulol has antifungal activity against T. mentagrophyes with a MIC of 1.8 μM. It is cytotoxic against A427 human lung and B16F10 mouse melanoma cells at concentrations of 25 and 200 μM, respectively, and inhibits lung metastasis in mice.
Reticulol is an isocoumarin metabolite shown to inactivate topoisomerase I.
Reticulol is an isocoumarin metabolite produced by selected species of Streptomyces. Reticulol was first described as a potent inhibitor of cyclic nucleotide phosphodiesterase but more recent research has demonstrated a topoisomerase I inactivation mechanism. Reticulol also causes dose dependent inhibition of lung metastasis in the B16F10 melanoma model.
