A method of increasing expression of a molecular chaperon by a cell and/or enhancing the activity of a molecular chaperon in cells is provided. The method comprises treating a cell that is exposed to a physiological stress which induces expression of a molecular chaperon by the cell with an effective amount of a certain hydroxylamine derivative to increase the stress. Alternatively, an hydroxylamine derivative can be administrated to a cell before it is exposed to a physiological stress which induces expression of a molecular chaperon by the cell. Preferably, the cell to which an hydroxylamine derivative is administered is an eukaryotic cell. The hydroxylamine derivative corresponds to the formulae (I) or (II).
The invention also provides novel hydroxylamine derivatives falling within the scope of the formulae (I) and (II) as well as pharmaceutical and/or cosmetical compositions comprising the said compounds.
提供了一种通过细胞增加分子伴侣的表达和/或增强细胞中分子伴侣活性的方法。该方法包括使用一定量的某种羟胺衍生物处理暴露于诱导细胞分子伴侣表达的生理应激下的细胞,以增加压力。另外,可以在细胞暴露于诱导细胞分子伴侣表达的生理应激之前给细胞施加羟胺衍生物。最好,接受羟胺衍生物处理的细胞是真核细胞。羟胺衍生物对应于公式(I)或(II)。本发明还提供了落在公式(I)和(II)范围内的新型羟胺衍生物,以及包含所述化合物的药物和/或化妆品组合物。
