A new class of molecules, C1-OH tributanoylated hexosamines, including, for example, Ga1NAc, G1cNAc and ManNAc, are demonstrated to increase cartilage-like tissue accumulation by IL- 1β-stimulated chondrocytes. Furthermore, all three molecules reduced NFKB1 and ΙκΒα driven gene expression, consistent with NFκB inhibitory properties of these analogs. Ga1NAc-a exposure produced the greatest ECM accumulation by IL-Ιβ- stimulated chondrocytes. However, Ga1NAc-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.
一种新的分子类别,C1-OH三丁酰化己糖胺,包括例如Ga1NAc、G1cNAc和ManNAc,已被证明能够通过IL-1β刺激的软骨细胞增加软骨样组织的积累。此外,这三种分子均减少了NFKB1和ΙκΒα驱动的基因表达,与这些类似物的NFκB抑制性质一致。Ga1NAc-a暴露产生了IL-Ιβ刺激的软骨细胞中最大的ECM积累。然而,Ga1NAc-a暴露在MSC暴露中产生了相反的效果,观察到ECM积累减少。这些发现支持了NFκB信号在肢体发育和生长板软骨发生过程中的功能。本发明展示了这一新类己糖胺类似物作为治疗软骨损伤的疾病修饰剂的能力。
