Abstract: A newly developed butane-tetraol-based amphiphilic compound, a method of preparing the same, and a method of extracting, solubilizing, stabilizing, crystallizing or analyzing a membrane protein using the amphiphilic compound are provided. The butane-tetraol-based compound is found to have a central structure exhibiting chirality, and isomers of the compound have clearly different characteristics according to the stereochemistry of the central structure, thereby making it possible to select compounds suitable for the uses thereof. Also, the compound can be used to effectively extract a membrane protein, which has more various structures and characteristics than conventional compounds, from cell membranes and stably store the membrane protein in an aqueous solution for a long time, and thus analyze the function and structure of the membrane protein.

Abstract: Provided are a newly developed norbornene-based amphiphilic compound, a method for preparing the same, and a method for extracting, solubilizing, stabilizing, crystallizing or analyzing a membrane protein using the same. In addition, the compound may effectively extract membrane proteins having various structures and characteristics, compared to a conventional compound, from cell membranes, and may be stably stored in an aqueous solution for a long period of time, and therefore may be used in their functional analysis and structural analysis. The structural and functional analyses of membrane proteins are the most noticeable field in biology and chemistry today due to a close relationship to the development of new drugs.
