چکیده

We describe a class of zwitterionic sulfobetaine (SB) lipids with fascinating salt-dependent properties. SB lipids are zwitter-neutral across a broad pH range; however they have negative surface potentials in the presence of anions and two salt-dependent transition temperatures. These new SB lipids provide insight on the role of charge orientation at the membrane interface and may be useful components in drug delivery systems.

A nondenaturing zwitterionic detergent for membrane biochemistry: design and synthesis.

The synthesis and evaluation of a new detergent that is a zwitterionic derivative of cholic acid is presented. This detergent combines the useful properties of both the sulfobetaine-type detergents and the bile salt anions. The new detergent proved to be effective at solubilizing membrane proteins in a nondenatured state.

A comparative study of zwitterionic ligands-mediated mineralization and the potential of mineralized zwitterionic matrices for bone tissue engineering.

Cationic and anionic residues of the extracellular matrices (ECM) of bone play synergistic roles in recruiting precursor ions and templating the nucleation, growth and crystalline transformations of calcium apatite in natural biomineralization. We previously reported that zwitterionic sulfobetaine ligands can template extensive 3-dimensional (3-D) hydroxyapaptite (HA)-mineralization of photo-cr...

Synthesis and characterization of novel zwitterionic lipids with pH-responsive biophysical properties.

We report the synthesis and biophysical characterization of a novel class of zwitterionic lipids (ZL) with head groups containing a 3° or 4° amine and carboxylate. ZL form stable liposomes that exhibit head group dependent, pH-responsive biophysical characteristics. These lipids may be suitable components for drug delivery applications due to their ease of synthesis and unique pH-dependent prop...

Carboxybetaine, Sulfobetaine, and Cationic Block Copolymer Coatings: A Comparison of the Surface Properties and Antibiofouling Behavior

Two different zwitterionic block copolymers (BCs) and a cationic BC were synthesized from the same BC precursor, which consisted of a polystyrene (PS) block and a poly[N-(3-dimethylamino-1-propyl)acrylamide] block. The zwitterionic BCs contained the dimethylammonioacetate (carboxybetaine) and dimethylammoniopropyl sulfonate (sulfobetaine) groups. Thin films cast from these polymers were investi...
