  Isocytosine H2-receptor histamine antagonists. IV. The synthesis and biological activity of donetidine (SK&F 93574) and related compounds

  摘要：

  The synthesis and biological activity of some novel 2-amino-4-pyrimidone derivatives is described. Side-chains associated with H-2-antagonist activity am attached through the 2-amino group, whilst a range of 2-hydroxypyridine containing moieties are substituted at the 5-position of the pyrimidone ring. Good H-2-receptor histamine antagonist activity is observed with all the series and the majority of the compounds are selective for the H-2-receptor. High aqueous solubility and iv potency coupled with an extended duration of biological activity in animal models led to compound 16c, 2-[2-(5-dimethylaminomethyl-2-furanylmethyl-thio)ethylamino]-5-(2-hydroxypyrid-4-ylmethyl)-4-pyrimidone (donetidine, SK&F 93574) being selected for clinical investigation as a potential parenterally administered therapeutic agent.

  A chemical process is described for the preparation of H2-antagonists or precursors thereof, of the formula (V): wherein R' is 5-methylimidazol-4-yl, furan-2-yl or 5-dimeth- ylaminomethylfuran-2-yl and R2 is 3,4-methylenedioxyphenyl or optionally protected 2-hydroxypyrid-4-yl; which process comprises reacting a compound of the formula (VI) with a compound of the formula (VII): wherein R3 is C1-6alkyl; and thereafter if desired deprotecting a protected hydroxy group, converting a compound wherein R1 is furan-2-yl into a compound wherein R1 is 5-di- methylaminomethylfuran-2-yl, and/or forming a pharmaceutically acceptable salt.

  描述了一种制备式(V)的 H2-拮抗剂或其前体的化学工艺： 其中 R'为 5-甲基咪唑-4-基、呋喃-2-基或 5-二甲基氨基甲基呋喃-2-基，R2 为 3,4-亚甲基二氧苯基或经选择保护的 2-羟基吡啶-4-基；该工艺包括使式（VI）化合物与式（VII）化合物反应： 其中 R3 为 C1-6 烷基；然后，如果需要，对受保护的羟基进行脱保护，将 R1 为呋喃-2-基的化合物转化为 R1 为 5-二甲氨基甲基呋喃-2-基的化合物，和/或形成药学上可接受的盐。
