The invention relates to a guanidine of the formula:-
in which R1 and R2 are H, Ci-io alkyl, C3-8 cycloalkyl or cycloalkylalkyl in which the alkyl part is C1-6 and the cycloalkyl part is C3-8, each of the alkyl, cycloalkyl and cycloalkylal- kyls being optionally substituted by one or more halogens selected from F, Cl and Br, provided that at least one of R' and R' is a halogen substituted alkyl, cycloalkyl or cycloalkyl-alkyl and provided that there is no halogen substituent on the carbon directly attached to the nitrogen;
ring X is phenyl carrying 1 or 2 optional substitutents or a 5- or 6-membered heterocyclic aromatic ring containing 1, 2 or 3 hetero atoms selected from 0, N and S, which heterocyclic ring may, carry a single optional substituent selected from F, Cl, Br, I, C1-6 alkyl, C1-6 alkoxy, C1-6 alkylthio, trifluoromethyl, hydroxy and amino;
Y is 0, S, a direct bond, methylene, vinylene, SO or NR4 in which R4 is H or C1-6 alkyl;
m is 0 to 4 and n is 1 to 5, provided that when Y is 0, SO or NR4, n is 2 to 5;
R3 has various significances; and the pharmaceutically-acceptable acid-addition salts thereof.
Manufacturing processes and pharmaceutical compositions are also described.
本发明涉及一种胍,其式如下:- 其中 R1 和 R2 为 H、Ci-io 烷基、C3-8 环烷基或环烷基(其中烷基部分为 C1-6,环烷基部分为 C3-8),每个烷基、环烷基和环烷基可任选被选自 F、Cl 和 Br 的一种或多种卤素取代,条件是 R' 和 R' 中至少有一个是被卤素取代的烷基、环烷基或环烷基烷基,且与氮直接相连的碳上没有卤素取代基;
环 X 是带有 1 或 2 个任选取代基的苯基,或含有 1、2 或 3 个选自 0、N 和 S 的杂原子的 5 或 6 元杂环芳香环,该杂环可带有 1 个选自 F、Cl、Br、I、C1-6 烷基、C1-6 烷氧基、C1-6 烷硫基、三氟甲基、羟基和氨基的任选取代基;
Y为0、S、直接键、亚甲基、亚乙烯基、SO或NR4,其中R4为H或C1-6烷基;m为0至4,n为1至5,但当Y为0、SO或NR4时,n为2至5;R3具有各种意义;及其药学上可接受的酸加成盐。
此外,还描述了制造工艺和药物组合物。
