The invention concerns novel renin-inhibitory peptides which are useful for treating renin-assocated hypertension, hyperaldosteronism, and congestive heart failure. Processes for preparing the peptides, compositions containing them and methods of using them are included. Also included is a diagnostic method which uses the compounds to determine the presence of renin-associated hypertension or hyperaldosteronism.

The present invention provides a novel process for the preparation of droxidopa, a synthetic amino acid precursor of norepinephrine. The process is a stereoselective process for the preparation of droxidopa using asymmetric induction and thus avoids synthetic process involving chiral resolution. The present invention also provides novel intermediates of formula V and formula VI.

The invention relates to hydroxypyridinone derivatives, their metal complexes, their preparation and their use for preparing conjugates with biomolecules. The conjugates are suitable as contrast agents in NMR diagnosis. A high relaxivity is achieved and the NMRD maximum is raised through a specific design of the ligands.
