    摘要: Described are ortho carboxy phenol derived acetals and compositions containing ortho carboxy phenol derived acetals which are useful for delivering biologically active compounds to cells. The acetals can be used to reversibly link up to three different molecules and have rapid hydrolysis kinetics in conditions which are present in a cell as well as in vivo. Cleavage of the acetal enhances delivery of the biologically active compound.

    摘要: A method for refolding an enzyme from a misfolded configuration to a second native and active configuration is presented. The method comprises adding a linear alkyl detergent to a misfolded enzyme to form an enzyme-detergent complex. Then the enzyme-detergent complex is contacted with a cyclodextrin to allow the enzyme to assume a second active configuration. The misfolded enzyme may have been previously denatured by heat or by chemical means other than a detergent.
