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.

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 reaction medium in a straightforward fashion. The process involves increasing the pH to above 5 a value in the range of 3 to 7 with sodium hydroxide, addition of sodium bisulphite and/or sodium dithionite, addition of seed crystals, cooling slowly, and washing the collected precipitate with water.

摘要: The present invention relates to compounds having 5-hydroxytryptamine receptor modulating activity, in particular compounds having an acidic moiety held distant from the 5-HT pharmacophore by a rigid linker group, to compositions containing such compounds and methods of treatment using them. Such compounds have an increased affinity for the 5-HT receptor and a reduced hERG effect. Certain compounds of the invention further exhibit an angiotensin II receptor modulating activity. Claimed are compounds of formula (I): HT-L-A. HT is a 5-HT receptor modulating moiety containing a basic nitrogen atom; A is an acid moiety; L is a linker moiety.
