    摘要: The invention provides a composition of matter of the formula (I): VnullLnullR where V is an organic group having binding affinity for an angiotensin II receptor site, L is a linker moiety or a bond, and R is a moiety detectable in in vivo imaging of a human or animal body, with the provisos that where V is angiotensin or a peptidic angiotensin derivative or analog then VnullLnullR is other than a non-metal radionuclide substituted peptide (e.g. 125I substituted angiotensin II) and LnullV is other than simply a peptide with a chelating agent amide bonded to a side chain thereof. This composition of matter may be used to image cardiovascular diseases and disorders.

    摘要: The invention provides a process by which ultra low salt content triiodinated aromatic compounds may be isolated from a highly acidic hot triiodination raction medium in a straightforward fashion. The process involves increasing the pH to above 5 with sodium hydroxide, addition of sodium bisulphite and/or sodium dithionite, addition of seed crystals, cooling slowly, and washing the collected precipitate with water.
