Abstract: The present invention relates to a mesitylene-cored amphiphile, a method of preparing the same and a method of extraction, solubilization, stabilization, crystallization or analysis of a membrane protein using the same. When a mesitylene-cored compound according to the present invention is used, membrane proteins can be stored in a stable conformation for a long time in an aqueous solution in comparison with conventional compounds, by which the membrane proteins are usable in both functional and structural analyses thereof. The functional and structural analyses of membrane proteins are one of the fields that are most spotlighted in current biology and chemistry. The present invention can be used to research on a protein structure closely related to new drug development.

Abstract: The invention provides tandem facial amphiphiles for biochemical manipulations and characterization of membrane proteins, such as intrinsic membrane proteins. Members of this new family display favorable behavior with several membrane proteins. These amphiphiles can form relatively small micelles, and small changes in amphiphile chemical structures can result in large changes in their physical properties. The tandem facial amphiphiles can be used to aid the solubilization, isolation, purification, stabilization, crystallization, and/or structural determination of membrane proteins.

Abstract: Bringing membrane proteins into aqueous solution generally requires the use of detergents or other amphiphilic agents. The invention provides a new class of amphiphiles, each of which includes a multi-fused ring system as a lipophilic group. These new amphiphiles confer enhanced stability to a range of membrane proteins in solution relative to conventional detergents, leading to improved structural and functional stability of membrane proteins, including integral membrane proteins. Accordingly, the invention provides new amphiphiles for biochemical manipulations and characterization of membrane proteins. These amphiphiles display favorable behavior with membrane proteins and can be used to aid the solubilization, isolation, purification, stabilization, crystallization, and/or structural determination of membrane proteins.

The compounds can be used to aid the isolation of membrane proteins, for example, to aid their solubilization and/or purification. The compounds can also be used to aid the functional and structural determination of membrane proteins, including their stabilization and crystallization.

Accordingly, lower amounts of the compounds are required for effective solubilization of membrane proteins. The compounds can be used aid the solubilization, isolation, purification, stabilization, crystallization, and/or structural determination of membrane proteins.
