The invention concerns novel piperidine derivatives of the formula (I) ##STR1## and the pharmaceutically acceptable acid addition salts thereof, wherein R.sup.1 represents (lower)alkyl, R.sup.2 represents a phenyl group optionally substituted by one or more (lower)alkyl, (lower)alkoxy, halogen, amino, (lower)alkylamino, di(lower)alkylamino or trifluoromethyl substituents and X represents=O; ##STR2## [where R.sup.3 and R.sup.4 both represent hydrogen, both represent the same (lower)alkyl or one is hydrogen and the other is (lower)alkyl or R.sup.3 and R.sup.4 together represent an alkylene group such that the ##STR3## is a cyclic ketal group containing 2 or 3 carbon atoms]; or ##STR4## [where OR is hydroxy, etherified hydroxy or esterified hydroxy]. The compounds possess anti-depressant activity.
该发明涉及公式(I)的新型哌啶衍生物及其药用可接受的酸盐,其中R.sup.1代表(较低)烷基,R.sup.2代表一个苯基,可以选择地被一个或多个(较低)烷基,(较低)氧烷基,卤素,氨基,(较低)烷基氨基,二(较低)烷基氨基或三氟甲基取代,X代表=O;[其中R.sup.3和R.sup.4均代表氢,均代表相同的(较低)烷基或一个是氢,另一个是(较低)烷基或R.sup.3和R.sup.4一起代表一个烷基基团,使得##STR3##是一个含有2个或3个碳原子的环戊醚基团];或##STR4##[其中OR是羟基,醚化羟基或酯化羟基]。这些化合物具有抗抑郁活性。
