N-alkenyl (or N-alkynyl)-N'-[2-(aminoalkyl)-4-thiazolyl- methylthioalkyl]guanidines, thioureas, ethenediamines and related compounds of the following formula
wherein each of R' and R2 are individually H or (C1-C4)-alkyl, one of R' and R2 can be benzyl or benzoyl, and when taken together with the nitrogen to which they are attached, form a saturated heterocyclic ring containing from 5 to 7 ring atoms including 1 or 2 heteroatoms; except that only one of R' and R2 can be H when Z is CH2;
R3 is H or (C1-C3)alkyl;
Z is 0, S or CH2;
n is 2 or 3 when Z is S or 0 and is 1, 2 or 3 when Z is CH2;
m is 1. 2 or 3;
R6 is H or CH3;
wherein A is N-CN, N-NO2, CH-NO2, S, 0, NH, N-(C1-C4)alkyl, N-SO2-aryl, N-SO2-(C1-C4)alkyl, N-CO-NH2, N-CO-(C1-C4)alkyl, N-C02(C,-C4)alkyl, CH-S02-aryl or CH-SO2-(C1-C4)alkyl, wherein aryl is phenyl, halophenyl, (C1-C4)alkylphenyl or (C1-C4)alkyloxy- phenyl; and R is (C2-C4)alkenyl or (C2-C4)alkynyl; and R8 and R9 are individually H, CH3 or C2H5, with the proviso that the total number of carbon atoms in the group CR8R9R be less than 7; or a pharmaceutically-acceptable salt thereof. The compounds are H2 receptor antagonists, useful in inhibiting gastric acid secretion in mammals.

其中,R'和 R2 分别为 H 或(C1-C4)-烷基,R'和 R2 中的一个可以是苄基或苯甲酰基,当它们与所连接的氮结合在一起时,形成一个含有 5 至 7 个环原子(包括 1 或 2 个杂原子)的饱和杂环;但当 Z 为 CH2 时,R'和 R2 中只有一个可以是 H;
R3 是 H 或 (C1-C3) 烷基;
Z 是 0、S 或 CH2;
当 Z 为 S 或 0 时,n 为 2 或 3;当 Z 为 CH2 时,n 为 1、2 或 3;
m 是 1、2 或 3;
R6 是 H 或 CH3;
其中 A 是 N-CN、N-NO2、CH-NO2、S、0、NH、N-(C1-C4)烷基、N-SO2-芳基、N-SO2-(C1-C4)烷基、N-CO-NH2、N-CO-(C1-C4)烷基、N-C02(C,-C4)烷基、CH-S02-芳基或 CH-SO2-(C1-C4)烷基,其中芳基是苯基、卤代苯基、(C1-C4)烷基苯基或(C1-C4)烷氧基苯基;R为(C2-C4)烯基或(C2-C4)炔基;R8和R9分别为H、CH3或C2H5,但CR8R9R基团中的碳原子总数应少于7;或其药学上可接受的盐。这些化合物是 H2 受体拮抗剂,可用于抑制哺乳动物的胃酸分泌。
