Aromatic hydroxylated derivatives of spiro[indan-1,3'-pyrrolidine], designed as conformationally restricted analogs of profadol, were synthesized and pharmacologically evaluated in mice for analgesia and other central nervous system activities. None of the compounds synthesized were as potent as profadol in writhing and hot plate tests, but the 4-hydroxy derivative exhibited codeine-level analgesia in the tests.
螺[茚满-1,3'-吡咯烷]的芳香族羟基化衍生物被设计为普罗法多的构象受限类似物,已合成并在小鼠身上进行了镇痛及其他中枢神经系统活性的药理学评估。在扭体和热板试验中,所合成的化合物均不如普罗法多有效,但4-羟基衍生物在试验中表现出与可待因相当的镇痛效果。
