| titleOfInvention | Hydropyridine derivatives |
| abstract | Hydropyridine derivatives of the formula <IMAGE> (I) in which R1 represents carboxy, lower alkoxycarbonyl, carbamoyl, N-lower alkylcarbamoyl or N,N-di-lower alkylcarbamoyl, R2 represents hydrogen, an optionally etherified or acylated hydroxy group or an optionally acylated amino group, and R3 represents a radical of the formula R- (Ia), R-alk1- (Ib) or R'=alk2- (Ic) in which R represents a benzocycloalkenyl radical having a total of from 8 to 12 ring carbon atoms which is bonded via a saturated carbon atom and which is unsubstituted or is mono- or poly-substituted in the benzo moiety by hydroxy, lower alkoxy, lower alkanoyloxy, halogen, lower alkyl and/or by trifluoromethyl, and/or subsituted in the alpha -position by lower alkyl, and R' represents a benzocycloalkylidene radical having a total of from 8 to 12 ring carbon atoms which is unsubstituted or is mono- or poly-substituted in the benzo moiety by hydroxy, lower alkoxy, lower alkanoyloxy, halogen, lower alkyl and/or by trifluoromethyl, and alk1 represents lower alkylene or lower alkylidene and alk2 represents lower alkyl- omega -ylidene, wherein the dotted line is intended to show that there may be a single bond or especially a double bond, and 3-aminopropionic acid compounds of the formula R3-NH-CH2CH2-R1 (IVc) in which R1 and R3 have the meanings given above, and their pharmaceutically acceptable salts, have nootropic properties and can be used as nootropic active ingredients in medicaments. They are manufactured by methods known per se. |
