    • The present invention relates to novel materials, particularly biomaterials, in form of a precipitate, comprising at least an anionic polymeric component which is as such soluble in water and an amphiphilic ammonium-type component, which precipitate is obtainable by a process including the following steps: 1. contacting the anionic polymeric component and an cyclodextrin component in an aqueous medium, and 2. adding to the mixture obtained in step 1 said amphiphilic ammonium-type component, wherein said components are present in amounts effective to form said precipitate, and preferably to corresponding precipitates additionally comprising said cyclodextrin component. Both types of precipitates may optionally comprise one or more further components. The precipitates are particularly useful as controlled-release depot formulations suitable for long-lasting delivery of said further components. The further components incorporated into the precipitates can be pharmaceutical compounds, pesticides, agrochemicals, colorants, diagnostics, enzymes, foodstuffs etc.

    • New inclusion complexes which are stable in their so-lid state formed of SIN-1A and cyclodextrins or cyclodextrin derivatives and optionally also containing ions as catalyst or stabilizer. The complexes release nitric oxide at room temperature upon dissolving in water or aqueous systems. The ions are preferably carboxylic acid anions such as acetate, formiate, propionate, ascorbinate, tartarate and/or lactate and/or inorganic acid anions such as phosphate, phosphite, borate, carbonate, hydrocarbonate, sulfate, sulfite and/or cations such as alkali and/or ammonium. Pharmaceutical compositions as well as kits containing the complexes. The kits are to be used as NO-liberating standards to release NO in a predictable amount and rate on dissolving in aqueous media. Processes for the preparation of the complexes by subjecting at a suitable pH SIN-1 to the catalytic action of ions to shift the equilibrium towards formation of SIN-1A in the presence of cyclodextrins or cyclodextrin derivatives capable to form inclusion complexes, whereby the SIN-1A formed is immediately complexed and stabilized and isolating in the solid state the obtained new complexes optionally containing ions. A preferred process includes reacting SIN-1 and a cyclodextrin or cyclodextrin derivative in the solid state in the presence of a salt as a catalyst by thoroughly admixing or milling the components together or by freeze drying an aqueous, oxygen-free solution containing the components, followed preferably by "second drying" in vacuo.
