    摘要: N-(12-Nitroxydodecyl)-6-(4-ethyl or isopropyl-1-piperazinyl)pyridine-3-carboxamide or physiologically acceptable salts thereof. The said compounds have excellent inhibiting activity of cerebral edema, especially ischemic cerebral edema, and inhibiting activity of delayed neuronal death (an inhibiting activity of Ca-influx in neuronal cells). Cerebral edema is a pathologic condition accompanying cerebrovascular disorders, especially the acute stage cerebrovascular disorders and then the compounds are useful as an inhibiting agent for cerebral edema or a therapeutic agent for cerebrovascular disorders. Moreover, because the compounds do hardly show a behavior suppressing action, which is considered to be side effect in treating cerebrovascular disorders at the acute stage, they are an excellent therapeutic agent for, in particular, the acute stage cerebrovascular disorders. Moreover, the compounds show a cerebral protective activity (an anti-anoxic activity), an activity of increasing cerebral blood flow, and an activity of inhibiting lipid peroxidation, and these activities may lead to the increased utility as a therapeutic agent for cerebrovascular disorders.

    摘要: Pyridinecarboxamide derivatives of the formula ##STR1## (wherein n represents an integer of 14-18, and R represents a hydrogen atom or a straight or branched C.sub.1 -C.sub.4 alkyl group) or physiologically acceptable salts thereof. The compounds have excellent inhibiting activity of cerebral edema, especially ischemic cerebral edema, and inhibiting activity of delayed death of neuronal cells (an inhibiting activity of Ca-influx in neuronal cells). Cerebral edema is a pathologic condition accompanying cerebrovascular disorders, especially the acute stage of cerebrovascular disorders and then the compounds are useful as an agent for inhibiting cerebral edema or a therapeutic agent for cerebrovascular disorders. Moreover, the compounds have no hypotensive action which is considered to be side-effect in treating the acute stage cerebrovascular disorders and hardly show a behavior suppressing action so that they are an excellent therapeutic agent for, in particular, the acute stage cerebrovascular disorders. Moreover, the compounds show a cerebral protective activity (an anti-anoxic activity), an increasing activity of cerebral blood flow, and an inhibiting activity of lipid peroxidation and these activities may lead to the increased utility as a therapeutic agent for cerebrovascular disorders.

    摘要: Four different optical isomers of a new compound, 1-[2'-(o-methoxyphenoxy)-1'-methylethylamino]-3-(4"-isocarbostyriloxy)-2-propanol are now provided as new substances. These four optical isomers are now named as (2R, 1'S)-1-[2'-(o-methoxyphenoxy)-1'-methylethylamino]-3-(4"-isocarbostyriloxy)-2-propanol, (2S, 1'S)-1-[2'-(o-methoxyphenoxy)-1'-methylethylamino]-3-(4"-isocarbostyriloxy)-2-propanol, (2S, 1'R)-1-[2'-(o-methoxyphenoxy)-1'-methylethylamino]-3-(4"-isocarbostyriloxy)-2-propanol, and (2R, 1'R)-1-[2'-(o-methoxyphenoxy)-1'-methylethylamino]-3-(4"-isocarbostyriloxy)-2-propanol, respectively. These four optical isomers have different activities for their .beta.-adrenergic-blocking effect and .alpha.-adrenergic-blocking effect and are useful as valuable agents for therapeutic treatment of various cardiovascular diseases, as compared to an optically inactive racemic mixture of said isomer compounds. These four optical isomers may be produced and isolated from each other by chromatographing (1'S)- or (1'R)-N-[2'-(o-methoxyphenoxy)-1'-methylethyl]-5-(4"-isocarbostyriloxymethyl)-2-oxazolidones to isolate either its (5R, 1'S)-isomer and its (5S, 1'S)-isomer, or its (5S, 1'R)-isomer and its (5R, 1'R)-isomer therefrom separately and then hydrolyzing each of these isolated isomers under alkaline conditions to obtain separately (2R, 1'S)-, (2S, 1'S)-, (2S, 1'R)- and (2R, 1'R)-1-[2'-(o-methoxyphenoxy)-1'-methylethylamino]-3-(4"-isocarbostyriloxy)-2-propanols.
