摘要:
This invention relates to novel compounds of the general formula (I) and the pharmaceutically acceptable acid addition salts thereof. In the general formula (I) ##STR1## wherein Lip, A.sup.1, A.sup.2, Het and n are defined as in the specification. The compounds of the general formula (I) inhibit the lipid peroxidation and therefore, they are useful for the treatment or prevention of diseases and conditions wherein the inhibition of lipid peroxidation is desirable.
摘要:
An N-benzoylamino acid compound of the formula (I), ##STR1## wherein R.sup.3 is an NR.sup.4 R.sup.5 group where R.sup.4 and R.sup.5 which are the same or different are selected from the group consisting of hydrogen, a hydroxyl group, a C.sub.1-12 alkyl group, a C.sub.1-4 alkyl group substituted by a hydroxyl group and a C.sub.1-4 alkyl group substituted by an amino group; R.sup.4 and R.sup.5 when taken together with the adjacent nitrogen form a substituted or unsubstituted 5- or 6-membered heterocyclic group, a 5- or 6-membered heterocyclic group containing an additional nitrogen atom, a 5- or 6-membered heterocyclic group containing an additional nitrogen atom and being substituted by an oxo group, a phenyl-substituted C.sub.1-4 alkyl group or C.sub.3-5 alkenyl group; with the proviso that when the heterocyclic group is piperazine, this heterocyclic group may also be substituted by a diaminopyrimidinyl or di(pyrrolidino)-pyrimidinyl group; n is an integer from 2 to 15; and their tautomers, racemates and the pure optically active individual isomers or mixtures thereof, and a pharmaceutically acceptable salt thereof is described. These compounds are useful for the treatment of patients suffering from disorders being in an indirect or direct connection with pathological oxidation processes occurring in the organism, particularly ischaemic and reperfusion tissue injuries, inflammations, atherosclerosis, or degenerative neurological disorders.
摘要:
The invention relates to novel N-benzoylamino acid derivatives of the general formula (I), ##STR1## wherein R.sup.1 and R.sup.2, which are the same or different, stand for a hydroxyl group optionally bearing an acetyl group; or a C.sub.1-6 alkoxy group optionally substituted by a phenyl group; n means an integer from 2 to 15 as well as their tautomers, racemates and optically active individual (pure) isomers or mixtures thereof and the salts of these compounds and pharmaceutical compositions containing these compounds. The invention relates also to a process for the preparation of compounds of the general formula (I). The compounds of general formula (I) inhibit the peroxidation of lipids and therefore, they are expected to be useful for the treatment of diseases being in an indirect or direct connection with pathological oxidation processes, chiefly for the treatment and/or prevention of ischaemic and reperfusion tissue injuries, inflammatory reactions, atherosclerosis, various degenerative neurological disorders as well as for delaying the natural process of the ageing of cells.
摘要:
The invention relates to a process for the production of new immunobiological preparations for the diagnosis, prophylaxis and/or treatment of Candida guilliermondii infections. According to the invention one proceeds as follows:(a) a Candida guilliermondii strain is propagated under aerobic conditions at 24-42.degree. C. on a culture medium containing assimilable carbon and nitrogen sources, the resulting population(s) is (are) maintained under identical conditions for a prolonged period, therafter the fungus cells are separated from the culture, washed, ruptured mechanically, extracted, the extract is treated with a polar organic solvent, and the resulting precipitate is converted into an immunobiological preparation either as such or after further purification, or(b) a Candida guilliermondii strain is cultivated for 48-72 hours under aerobic conditions at 24.degree.-42.degree. C. on a culture medium containing assimilable carbon and nitrogen sources, the resulting culture is optionally propagated further to produce two or three new populations, then the fungus cells are separated from the culture, washed, ruptured mechanically, extracted, then, if desired, a polar organic solvent is added to the extract, and the resulting precipitate is converted into an immunobiological preparation either as such or after further purification, or(c) a Candida guilliermondii strain is cultivated for 48-72 hours under aerobic conditions at 24.degree.-42.degree. C. on a culture medium containing assimilable carbon and nitrogen sources, then the culture is killed, the killed cells are separated and converted then into an immunobiological preparation either as such or after purification.
