title: WF14861, a new cathepsins B and L inhibitor produced by Colletotrichum sp. II. Biological properties.
abstract: WF14861, 3-(N-(1-(N-(4-aminobutyl)-N-(3-aminopropyl)carbamoyl)-2-(4-hydroxyphenyl )ethyl)carbamoyl)oxirane-2-carboxylic acid, was obtained from the culture mycelium of Colletotrichum sp. as a novel cathepsins B and L inhibitor. WF14861 also showed inhibitory activities against bone derived crude protease and other cysteine proteases in vitro. The compound ameliorated the tissue damage and the bone destruction models of low-calcium-diet-fed mouse and adjuvant arthritis rat model.
