Arohynapene-A And Arohynapene-B, New Anticoccidial Agents Produced By Penicillium Sp - Taxonomy, Fermentation, And Structure Elucidation
The Journal of antibiotics(1994)
摘要
Penicillium sp. FO-2295, a water isolate, was found to produce a series of new anticoccidial compounds. Two active compounds, designated arohynapenes A and B, were isolated from the fermentation broth of the producing strain by solvent extraction and preparative HPLC. Arohynapene A was deduced to be (2E,4E)-5-(5-hydroxy-2,6,8-trimethyl-5,6,7,8-tetrahydronaphtalene)-2,4pentadienoic acid, and arohynapene B was (2E,4E)-5-(2-hydroxymethyl-6,8-dimethyltetrahydronaphtalene)-2,4-pentadienoic acid. Arohynapenes inhibited the growth of Eimeria tenella in an in vitro assay using BHK-21 cells as a host. No schizont in the cells was observed at concentrations ranging above 35.0 mu M and 7.0 mu M for arohynapenes A and B, respectively.
