The substituted alkylamine derivatives represented by formula (I) ##STR1## wherein R.sup.1 represents (a) substituted or unsubstituted C.sub.2-6 alkenyl group, (b) substituted or unsubstituted C.sub.3-6 cycloalkenyl group, (c) substituted or unsubstituted C.sub.2-6 alkynyl group, (d) substituted or unsubstituted aryl group, (e) substituted or unsubstituted heterocyclic group, (f) fused heterocyclic group which may be substituted, or (g) group represented by the formula Ru.sup.11 -Ar wherein R.sup.11 is a heterocyclic group and Ar is a 5- or 6-membered aromatic ring which may contain a hetero N, O or S atom, and which may be substituted; ##STR2## represents a 5- or 6-membered aromatic ring which may contain a hetero N, O or S atom, and may be substituted by R.sup.7,

Substituted alkylamine derivatives

A substituted pyridine derivative represented by the general formula ##STR1## wherein R.sup.1 represents a phenyl or naphthyl group which may optionally be substituted by a substituent selected from the class consisting of a hydroxyl group, lower alkyl groups, lower alkoxy groups, cycloalkyl groups, lower alkoxycarbonyl groups, a phenyl group and halogen atoms; X represents an oxygen atom, a sulfur atom, a carbonyl group, or a group of the formula --CH(OH)-- or --N(R.sup.a)-- in which R.sup.a is a hydrogen atom or a lower alkyl group; Y represents a linear or branched lower alkylene group or a vinylene group which may optionally be substituted by a lower alkyl group, with the proviso that when X is an oxygen or sulfur atom, Y represents the lower alkylene group; R.sup.2 and R.sup.3 are identical or different and each represents a hydrogen atom or a lower alkyl group; R.sup.4 represents a hydrogen atom, a lower alkoxy group, a cycloalkyloxy group, a lower alkylthio group, a cycloalkylthio group, an aryloxy group, an aralkyloxy groups or a group of the formula ##STR2## in which R.sup.b and R.sup.c are identical or different and each represents a hydrogen atom or a lower alkyl group. or R.sup.b and R.sup.c, taken together, may form together with the adjacent nitrogen atom a 5- to 7-membered saturated heterocyclic ring which may optionally contain at least one additional hetero atom selected from the group consisting of oxygen, sulfur and nitrogen atoms and may optionally be substituted by a lower alkyl group; m and n are each 0 or 1, with the proviso that m and n are not 0 at the same time, or an acid addition salt thereof. This compound is useful as an antiulcer agent.

Anti-ulcer substituted pyridine derivatives

This invention provides a class of new indole derivatives which are useful as medicinal compounds having a mild inhibitory effect on the gastric acid secretion as well as a remarkably cytoprotective effects on gastric muscosa, and which are represented by the general formula: ##STR1##

Indole derivatives having gastric and antisecretory and cytoprotective

A new compound is produced which has the general formula: ##STR1## wherein R represents hydrogen atom or a lower alkyl group and which exhibits an immunopotentiating activity. This new compound as well as its pharmaceutically acceptable salts and hydrates are useful for immunotherapy and treatment of immune diseases and disorders in living animals including human beings. The new compound can be produced by reduction of a hydroxyterephthalic acid alkyl ester or by esterification of the corresponding 3-hydroxy-4-(hydroxymethyl)-benzoic acid.
