The invention relates to a group of tertiary 2,5-dialkyl-3-phenylpiperidine derivatives, having opiate-antagonistic activity represented by general formula 4,
wherein
S1 is hydrogen, an optionally esterified hydroxyl group or mercapto group, a group -NHS8 or -CONHS8, wherein S8 is hydrogen, alkyl having 1-6 C-atoms or alkylcarbonyl having 2-7 C-atoms;
S2 is hydrogen or, when S1 is hydrogen, one of the other meanings of Si, or
S1 and S2 together with the 2 carbon atoms of the benzene ring, constitute a heterocyclic group which consists of five or six ring atoms and which comprises a group -NH-and optionally as a second hetero atom may comprise an oxygen atom, sulphur atom or nitrogen atom;
S3 and S4 independently of each other are straight or branched alkyl or alkenyl having 1-6 C-atoms;
Ss is a straight or branched alkylene chain having 2-8 C-atoms;
X is the carbonyl group or ketalised carbonyl group or the group CHOH, -CONH-, -NHCO-, methylene, CHC6H5 or an oxygen atom or sulphur atom;
S6 is an alkyl group, cycloalkyl group or cycloalkylalkyl group having at most 10 C-atoms and optionally substituted with one or more groups 87, or is a phenyl group or phenylalkyl group having 1-4 C-atoms in the alkyl group and optionally substituted with one or more groups S7. and
S7 is alkyl, alkoxy or alkylthio having 1-4 C-atoms, amino, mono- or dialkylamino having 1-4 C-atoms per alkyl group, hydroxyalkyl, alkylcarbonyl , alkylaminocarbonyl or alkoxycarbonyl having 1-4 C-atoms in the alkyl group, nitro, cyano, halogen, trifluoromethyl, trifluoromethoxy, alkylsulphonyl having 1-4 C-atoms, or aminosuiphonyl.
These compounds have a pure opiate-antagonistic activity, i.e. without an agonistic activity component.

S1 和 S2 与苯环上的 2 个碳原子一起构成一个杂环基团,该杂环基团由 5 个或 6 个环原子组成,其中包含一个基团-NH,作为第二个杂原子可选择包含一个氧原子、硫原子或氮原子;
S3 和 S4 相互独立地为具有 1-6 个 C 原子的直链或支链烷基或烯基;
Ss 是具有 2-8 个 C 原子的直链或支链亚烷基;
X 是羰基或酮化羰基或 CHOH、-CONH-、-NHCO-、亚甲基、CHC6H5 或氧原子或硫原子;
S6 是最多具有 10 个 C 原子并可选择被一个或多个基团 87 取代的烷基、环烷基或环烷基烷基,或 是烷基中具有 1-4 个 C 原子并可选择被一个或多个基团 S7 取代的苯基或苯基烷基。
S7 是烷基、烷氧基或具有 1-4 个 C 原子的烷硫基、氨基、每个烷基具有 1-4 个 C 原子的单烷基或二烷基氨基、羟基烷基、烷基羰基、烷基氨基羰基或烷氧基羰基、硝基、氰基、卤素、三氟甲基、三氟甲氧基、具有 1-4 个 C 原子的烷基磺酰基或氨基水杨基。
这些化合物具有纯粹的阿片拮抗活性,即不含激动活性成分。
