| 摘要 |
Use of amidoxime carboxylic acid ester compound (I) or N-hydroxyguanidine carboxylic acid ester compound (II), as substitution of amidine-, N-hydroxyamidine- (amidoxime), guanidine- or N-hydroxyguanidine-functions of an active agent in a medicament to improve the solubility, bioavailability and/or blood-brain-barrier mobility of the medicament, is claimed, where the active agent is protease inhibitor, an inhibitor of factor Xa, factor VII or all protease of the coagulation cascade or a matriptase inhibitor, DNA- and RNA-intercalating compounds, or the N-methyl-D-aspartate-receptor-antagonist. Use of amidoxime carboxylic acid ester compound of formula (CH 3-C(NH 2)=N-O-C(=O)-(CH 2) n-C(=O)-OR 1) (I) or N-hydroxyguanidine carboxylic acid ester compound of formula (CH 3-NH-C(NH 2)=N-O-C(=O)-(CH 2) n-C(=O)-OR 1) (II), as substitution of amidine-, N-hydroxyamidine- (amidoxime), guanidine- or N-hydroxyguanidine-functions of an active agent in a medicament to improve the solubility, bioavailability and/or blood-brain-barrier mobility of the medicament, is claimed, where the active agent is protease inhibitor, preferably a thrombin inhibitor, an inhibitor of a factor Xa, factor VII, all protease of the coagulation cascade or a matriptase inhibitor, DNA- and RNA-intercalating compounds, inhibitor of viral enzyme or the N-methyl-D-aspartate-receptor-antagonist.
