The present invention generally relates to various compounds that are useful as vesicular acetylcholine transporter (VAChT) ligands. The invention further relates to methods of using these compounds and their radiolabeled analogs for the detection of neurodegenerative diseases including Parkinson's disease (PD), and Alzheimer's disease (AD).

The present invention concerns deuterated catecholamine derivatives as well as pharmaceuticals containing these compounds. In addition, the invention concerns the use of deuterated catecholamine derivatives as well as physiologically compatible salts thereof, and also pharmaceutical compositions, which contain these compounds, also in combination with enzyme inhibitors, for the treatment of dopamine deficiency diseases or diseases which are based on disrupted tyrosine transport or disrupted tyrosine decarboxylase, as well as other disorders.

This invention relates to novel substituted styryl benzylsulfones that are multikinase inhibitors and pharmaceutically acceptable acid addition salts thereof. The invention also provides compositions comprising a compound of this invention and the use of such compositions in methods of treating diseases and conditions beneficially treated by an agent that inhibits kinases, such as phosphatidylinositol 3-kinase (PI3-K) and polo-like kinase (PLK-1).

The present invention relates to a method for purification of 18F-labeled choline analogs in a solution injectable to a patient, prepared using non-gaseous synthesis paths, comprising a step of solid phase extraction (SPE) purification using a solid support, wherein the solid support used in the solid phase extraction purification has the characteristic to retain impurities and reagents from the solution but not the 18F-labeled choline analogs.
