Patent

CA 2064853

This invention is directed to a indole derivative represented by the general formula (1) (see fig. I) wherein R1 stands for alkyl of 1 to 5 carbon atoms, cycloalkylalkyl of 4 to 7 carbon atoms, cycloalkenylalkyl of 5 to 7 carbon atoms, aralkyl of 7 to 14 carbon atoms, trans-alkenyl of 4 or 5 carbon atoms, allyl, furanyl-2-ylalkyl of 1 to 5 carbon atoms, thienyl-2-ylalkyl of 1 to carbon atoms, vinyloxycarbonyl, trichloroethoxycarbonyl, benzyloxycarbonyl, alkanoyl of 1 to 5 carbon atoms, aralkylcarbonyl of 7 to 14 carbon atoms, 2-furoyl, thiophene-2-carbonyl, cycloalkylcarbonyl of 4 to 7 carbon atoms, alkenylcarbonyl of 3 to 8 carbon atoms, or anisoyl, R2 for a hdyrogen atom, alkyl of 1 to 3 carbon atoms, benzyl, or alkanoyl of 1 to 5 carbon atoms, R3 for a hydrogen atom, a fluorine atom, a chlorine atom, a bromine atom, nitro, or alkyl of 1 to 5 carbon atoms, R4 for a hydrogen atom, alkyl of 1 to 5 carbon atoms, benzyl, or phenyl, and R5 for a hdyrogen atom, hydroxy, or alkanoyloxy of 1 to 5 carbon atoms, providing that said general formula (1) embraces a (+) form, a (-) form, and a (~) form, or a pharmacologically acceptable salt thereof and to an immunorepressing agent having as an active component thereof the indole -232- derivative or the pharmacologically acceptable salt thereof.
