Analogues of classical H2‐receptor antagonistscontaining aminofurazan moieties as polar groups were synthesized and tested “in vitro” for their activities. Compounds containing 3‐amino‐4‐methylfurazan and 4‐amino‐3‐methylfuroxan substructures show good antagonistic properties. The compound containing the 3‐amino‐4‐phenylfurazan moiety is inactive. An SAR approach is discussed.
合成含有氨基呋喃基部分作为极性基团的经典 H2 受体拮抗剂的类似物,并在“体外”测试其活性。含有3-氨基-4-甲基呋喃和4-氨基-3-甲基呋喃亚结构的化合物显示出良好的拮抗作用。含有 3-氨基-4-苯基呋咱部分的化合物是无活性的。讨论了 SAR 方法。
