Abstract
A new class of molecules, C—OH tributanoylated hexosamines, including, for example, GalNAc, GlcNAc and ManNAc, are demonstrated to increase cartilage-like tissue accumulation by IL-1β-stimulated chondrocytes. Furthermore, all three molecules reduced NFKB1 and IκBα driven gene expression, consistent with NFκB inhibitory properties of these analogs. GalNAc-a exposure produced the greatest ECM accumulation by IL-1β-stimulated chondrocytes. However, GalNAc-a exposure produced an opposite effect on MSC exposure, where a decrease in ECM accumulation was observed. These findings are in support of the function of NFκB signaling during limb development and growth plate chondrogenesis. The present invention shows the capability of this new class of hexosamine analogs as disease-modifying agents for treating cartilage damage.
