Affinity Screening Using Competitive Binding with Fluorine-19 Hyperpolarized Ligands

Development of aptameric affinity ligands specific to human plasma coagulation factor VIII using SEC-SELEX

Protein specific aptamers are highly applicable affinity ligands in different fields of research and clinical applications. They have been developed against various targets, in particular, bio-macromolecules such as proteins. Among human proteins, the coagulation factors are the most attractive targets for aptamer selection and their specific aptamers had valuable characteristics in therapeutic...

Discovery of High-Affinity Protein Binding Ligands – Backwards

BACKGROUND There is a pressing need for high-affinity protein binding ligands for all proteins in the human and other proteomes. Numerous groups are working to develop protein binding ligands but most approaches develop ligands using the same strategy in which a large library of structured ligands is screened against a protein target to identify a high-affinity ligand for the target. While this...

Low affinity glucocorticoid binding site ligands as potential anti-fibrogenics

BACKGROUND Pregnane X receptor (PXR) agonists inhibit liver fibrosis. However, the rodent PXR activator pregnenolone 16alpha carbonitrile (PCN) blocks, in vitro, hepatic stellate cell-to-myofibroblast trans-differentiation and proliferation in cells from mice with a disrupted PXR gene, suggesting there is an additional anti-fibrogenic drug target for PCN. The role of the low affinity glucocorti...
