Piperidine compounds of the formula: ##STR1## or isomers thereof as well as pharmaceutically acceptable salts and/or hydrate forms thereof, and piperidine compounds of the formula: ##STR2## or isomers thereof as well as salt and/or hydrate forms thereof. In the above formulae, A represents a methylene group, an oxygen atom or a sulfur atom; B represents an oxygen atom or a sulfur atom; R.sup.1 and R.sup.2 independently represent a hydrogen atom, a lower alkyl group or an aralkyl group; R.sup.3 represents a hydrogen atom or an amino protecting group; Z represents an amino group or a protected amino group, a hydroxy group, or a reactive atom or group; m represents 1 or 2; and n represents the integer of 0 to 3. Piperidine compounds (I) possess an inhibitory activity against angiotensin-converting enzyme, and exhibit a long lasting hypotensive activity and are useful as antihypertensive agents. Piperidine compounds (II) are useful as intermediates for said piperidine compounds (I).
