Capillary electrophoretic study of small, highly sulfated, non-sugar molecules interacting with antithrombin.

Affinity CE (ACE) was used to study interactions of small, highly sulfated, aromatic molecules with antithrombin (AT). The high charge density of the small molecules induces differential migration of the complex resulting in a versatile method of assessing binding affinities, nature of interactions and site of binding on the inhibitor. Scatchard analysis of the interaction of three tetrahydrois...

Exploring new non-sugar sulfated molecules as activators of antithrombin.

New non-sugar, small, sulfated molecules, based on our de novo rationally designed activator (-)-epicatechin sulfate (ECS), were investigated to bind and activate antithrombin, an inhibitor of plasma coagulation enzyme factor Xa. For the activators studied, the equilibrium dissociation constant (K(D)) of the interaction with plasma antithrombin varies nearly 53-fold, with the highest affinity o...

Chiral Separation of Basic and Zwitterionic Drugs by Highly Sulfated Cyclodextrins Using Short-End Injection Capillary Electrophoresis Highly Sulfated Cyclodextrins Using Short-End Injection Capillary Electrophoresis

Due to high resolution power of sulfated cyclodextrins (HS-CDs), utilization of these selectors for chiral resolution of 7 basic and 2 zwitterionic drugs have been examined. Experiments were performed on a HP3DCE instrument equipped with an on-column diode array UV absorbance detector. Fused silica capillaries with an inner diameter of 50 ?m, an outer diameter of 365 ?m, and a total length of 4...
