| 摘要 |
The invention relates to novel, optically active cis and trans 14-(N-substituted aminomethyl)eburnane derivatives of formula (I), wherein R1 stands for hydrogen, a C1-6alkyl or C2-6alkenyl group; R2 means a C1-6alkyl, C2-6alkenyl or a hydroxy-C1-6alkyl group; or R1 and R2 represent together with the adjacent nitrogen atom to which they are attached, a 5 to 7-membered saturated ring, optionally containing one oxygen atom and/or one optionally substituted nitrogen atom as heteroatom; and n is 2 or 3, as well as pharmaceutically acceptable salts of these compounds. The compounds of the invention possess an antioxidative (lipid peroxidation-inhibiting) effect and therefore, they are useful for treating diseases connected with lipid peroxidation, such as ischaemic intestinal diseases, myocardial ischaemia, ischaemic cerebrovascular disturbances as well as some diseases of connective tissues, e.g. rheumatoid arthritis. The compounds of the invention are also suitable for treating or preventing cognitive disorders. |
