title: WF14861, a new cathepsins B and L inhibitor produced by Colletotrichum sp. I. Taxonomy, production, purification and structure elucidation.
abstract: WF14861, a novel cathepsins B and L inhibitor, was obtained from the culture mycelium of a fungus strain Colletotrichum sp. No. 14861. Spectroscopic analysis showed that WF14861 consisted of trans-epoxysuccinic acid, L-tyrosine and spermidine, WF14861 inhibited cathepsins B and L selectively.
