Hynapenes A, B and C, new anticoccidial agents produced by Penicillium sp. I. Production, isolation and physico-chemical and biological properties.
1993
Penicillium sp. FO-1611, a soil isolate, was found to produce a series of new anticoccidial compounds. Three active compounds, designated hynapenes A, B and C, were isolated from the fermetation broth of the producing strain by solvent extraction, silica gel column chromatography, gel filtration on Sephadex LH-20 and preparative HPLC. Hynapenes 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 123 μm, 34.7 μm and 34.7 μm for hynapenes A, B and C, respectively
