Quinolylpropylpiperidine derivatives of general formula (I) in which R
1a
is hydrogen, halogen, hydroxyl, amino, alkylamino, dialkylamino, hydroxyamino, alkoxyamino or alkylalkoxyamino and R
1b
is hydrogen, or R
1a
and R
1b
form an oxo, R
2
is carboxyl, carboxymethyl or hydroxymethyl, R
3
is alkyl either substituted with phenylthio optionally substituted with halogen, hydroxyl, alkyl, alkoxy, trifluoromethyl, trifluoromethoxy, carboxyl, alkoxycarbonyl, cyano or amino, or with cycloalkylthio (3 to 7 members) optionally substituted with halogen or trifluoromethyl, or with heteroarylthio (5 to 6 members and 1 to 4 heteroatoms chosen from N, O and S), optionally substituted with halogen, hydroxyl, alkyl, alkoxy, trifluoromethyl, trifluoromethoxy, carboxyl, alkoxycarbonyl, cyano or amino or R
3
is propargyl substituted with phenyl or heteroaryl as defined above, R
