Abstract: The invention relates to compounds of formula (I): wherein 0≦n≦3, 0≦m≦6, R3 and R4 together form phenyl, B represents heteroaryl, R1 and R2 represent hydrogen or groups as defined in the description. and medicinal products containing the same which are useful in treating or preventing arterial hypertension and cardiovascular diseases.

Abstract: Compounds of formula (I): 1

Abstract: The invention concerns a compound corresponding to general formula (1) wherein, in particular, R2 represents a phenylmethyl or naphthylmethyl or cyclohexylmethyl radical, 2- and 3-pryidinylmethyl, substituted on the cycle in meta or para position by an acid group or an alkyl radical of the type (CH2)n (with n=3 or 4) substituted in terminal position by an acid group; and R3 represents a hydrogen group or a linear or branched C1-C4 alkyl or alkylcycloalkyl with a C3-C6 cycloalkyl. The invention also concerns the use of a compound of general formula (I) for preparing a pharmaceutical composition for treating diseases related to proliferative processes, cancers and/or metastases.

Abstract: These compounds are represented by formula (I), in which each of R.sub.1 R.sub.2 =H, C.sub.1 -C.sub.8 alkyl, C.sub.3 -C.sub.7 cycloalkyl, or aromatic; (when R.sub.1 =H, R.sub.2 can be an amine function-protecting radical, amino acid residue or peptide fragment; R.sub.1 and R.sub.2 being capable of forming, with N, a 5-7 component ring); A=carbonyl or methylene; W=hydroxy, phenoxy, C.sub.1 -C.sub.8 alkoxy; phenoxy(C.sub.1 -C.sub.8 alkyl), amino, (C.sub.1 -C.sub.8 alkyl)amino, di(C.sub.1 -C.sub.8 alkyl)amino, (when A=carbonyl, W=amino acid residue or peptide fragment); Y=--OSO.sub.2 OR.sub.3 (II), --OPO(OR.sub.3).sub.2 (III), --(CH.sub.2 (.sub.m --SO.sub.2 OR.sub.3 (IV) or --(CH.sub.2).sub.m --PO(OR.sub.3).sub.2 (V) [R.sub.3 =H, C.sub.1 -C.sub.8 alkyl; m=1 to 4]; Z=cyclohexane, pyridyl or phenyl; n=0 to 4; on the condition that when Y=(II) or (III), -A-W is other than a sequence composed of natural amino acids.

Abstract: Peptides of formula: ##STR1## in which X=H or a radical which protects the amine gorup, R=H or SO.sub.3 H, A an D are:either different, and one of them donotes a radical ##STR2## and the other a radical ##STR3## m and n being between 1 and 5, and A and D form a ring by amidation of their side chains,or identical or different and denote: ##STR4## with p=1 or 2, and A and D form a ring by oxidative bridging between the sulfphur atoms; B and E=Met, NLe, Leu, Ser, Thr, allo-Thr, or Cys or Hcy, in which the OH or SH groups are free or protected;F=valency bond or Phe, Tyr(OCH.sub.3) or Cha;Q=H or alkyl (1 to 6 C), phenyl or phenylalkyl, these radicals being unsubstituted or substituted with fluorine atoms, and the amino acids are D, L or DL; are useful, in particular, as enuropsychotropic drugs.
