Thielavin B is a fungal metabolite that contains O-substituted salicylic acid. It inhibits cyclooxygenase, blocking both the conversion of arachidonic acid to Prostaglandin H2 (PGH2) and the conversion of PGH2 to PGE2 (, IC50s = 40 and 9 μM, respectively). Thielavin B also inhibits the reverse transcriptase of avian myeloblastosis virus, bacterial transglycosylases, and telomerase activity.
Thielavin B is a fungal metabolite of?Thielavia terricola that contains O-substituted salicylic acid. It is an inhibitor of viral reverse transcriptase and telomerase.
Thielavin B is a fungal metabolite closely related to thielavin A but reported to have a slightly different biochemical profile. Thielavins inhibit glucose-6-phosphatase. Thielavin B is a potent inhibitor of phospholipase C, and inhibits peptidoglycan formation and prostaglandin biosynthesis.
