thielavin a

Thielavin A is a fungal metabolite originally isolated from T. terricola that is related to thielavin B . Thielavin A inhibits COX, blocking both the conversion of arachidonic acid to prostaglandin H2 and the conversion of PGH2 to PGE2 . Thielavin A also inhibits glucose-6-phosphatase in rat liver microsomes (IC50 = 4.6 μM). It is a non-competitive inhibitor of α-glucosidase from S. cerevisiae (IC50 = 23.8 μM; Ki = 27.8 μM).

Thielavin B为Thielavin terricola产生的前列腺素生物合成抑制剂。该化合物能有效抑制内过氧物酶介导的前列腺素E2合成，并在静脉注射后显著降低大鼠因角叉菜胶引发的水肿。
