Like yanuthone X2, yanuthone X1 has been isolated from the filamentous fungus Aspergillus niger, but shows much lower antifungal activity towards the pathogenic yeast Candida albicans than yanuthone X2 (IC50 >100 muM for yanuthone X1, compared with = 51.7 +-4.7 muM for yanuthone X2). It has a role as an Aspergillus metabolite. It is a class II yanuthone, an enol ether and an acetate ester. It is functionally related to a yanuthone X2."}]
