    摘要： There are provided tripeptide compounds represented by the following formula ##STR1## wherein R.sub.1 represents a C.sub.1-10 alkyl group, a C.sub.4-7 cycloalkyl or C.sub.5-7 cycloalkyl-lower alkyl group, a phenyl or phenyl-lower alkyl group in which the benzene ring may optionally be substituted by a substituent selected from halogen, lower alkyl, lower alkoxy, phenyl, methylenedioxy, ethylenedioxy, amino, di(lower alkyl)amino and hydroxy, a naphthyl or naphthyl-lower alkyl group in which the naphthalene ring may optionally be substituted by a substituent selected from halogen, lower alkyl, lower alkoxy and hydroxy, a heterocyclic or heterocyclic-lower alkyl group in which the heterocycle is a saturated or unsaturated 5- or 6-membered ring containing a nitrogen, oxygen or sulfur atom as the hetero atom, and may optionally be substituted by a substituent selected from halogen, lower alkyl, lower alkoxy, amino, di(lower alkyl)amino, hydroxy, oxo and saturated 5- or 6-membered nitrogen-containing heterocyclic group, and further may optionally be fused to a benzene ring, or an imidazolylvinyl group; R.sub.2 represents a hydrogen atom, a C.sub.1-10 alkyl group or a benzyl group; R.sub.3 represents a group of the formula ##STR2## represents a benzene, cyclopentane or cyclohexane ring, R.sub.4 represents a hydrogen atom, a C.sub.1-10 alkyl group or a benzyl group, p is 0 or 1, q is 1, 2, or 3, and X represents a phenyl group which may optionally be substituted by a substituent selected from halogen, lower alkoxy and hydroxy, a C.sub.4-8 cycloalkyl group, or a C.sub.5-7 cycloalkyl group which is fused to a benzene, and Y represents a hydrogen atom or a lower alkyl group, or X and Y, together with the nitrogen and carbon atoms to which they are bonded, forms a 5- or 6-membered heterocycle which may contain a nitrogen, oxygen or sulfur atom,W represents a single bond, --O-- or --NH--, T represents a single bond, ##STR3## and m is 2 or 3, or salts thereof and processes for production thereof. The compounds are useful as antihypertensive agents.
