  • Inclusion complex of 7-isopropoxy-isoflavon formed with cyclodextrin, the preparation thereof and pharmaceutical compositions containing these compounds as active ingredients
    Patent number: 5043326
    Abstract: The invention relates to the inclusion complexes of 7-isopropoxy-isoflavon formed with cyclodextrin or cyclodextrin derivatives as well as to the pharmaceutical compositions containing these inclusion complexes as active ingredient. The invention further relates to the preparation of the new inclusion complexes.The new inclusion complex according to the invention shows higher dissolution and resorption properties as compared to the active ingredient administered per se.
    Type: Grant

  • Process for the intensification of microbiological conversions of steroids using cyclodextrin additives
    Patent number: 4528271
    Abstract: Microbiological conversions of cyclodextrins are intensified by adding to the reaction mixture 0.2 to 3 moles of .alpha.-, .beta.- or .gamma.-cyclodextrin or an optical mixture thereof pro mole of the steroid substrate, before, at the beginning or during the conversion. The cyclodextrin if desired, can be removed after the reaction. In this way the reaction velocity can be increased, the reaction time is reduced, the substrate concentration in the solution, i.e. its solubility is increased or the so called product inhibition may be avoided. In certain cases of more alternatives the desired reaction can be catalyzed and in this manner the selectivity is increased.

  • Process for the preparation of an inclusion complex of N-(1--phenylethyl)-3,3-diphenylpropylamine and the hydrochloride thereof respectively with cyclodextrin
    Patent number: 4518588
    Abstract: An inclusion complex is disclosed of N-(1-phenylethyl)-3, 3-diphenyl-propylamine or its hydrochloride complexed with a cyclodextrin as well as a process for the preparation thereof and pharmaceutical compositions containing same. The new inclusion complexes have coronary dilatory activity and have greater water soluble than simple N-(1-phenylethyl)-3, 3-diphenyl-propyl amine or the hydrochloride thereof.
