Simplified aminocoumarin analogues, either noviosylated or simple basic heterocycle attached 3-amidocoumarin compounds, are known to be promising anticancer agents targeting the C-terminal ATPbinding site of Hsp90. In this study, 3'-amino isosteric replacement in the noviose moiety of two known noviose containing Hsp90 C-terminal inhibitors was synthetically realized for the first time. In vitro evaluation of these compounds suggested that the introduction of a basic amino group into the noviose subunit resulted in significant improvement of their cytotoxicities.
