synthesize compounds in which the 1,2,4-oxadiazole moiety replaced the amide bond of ONO3805 and to evaluate its 5α-reductase inhibitory activity as a potential benign prostatic hyperplasia therapeutic target. Four 1,2,4-oxadiazole derivatives, 1, 2, 8, and 20, were evaluated in vitro against 5α-reductase of rat liver microsome. The prepared 1 and 2 possessed similar binding affinity (Ki) to that of ONO3805
本研究的目的是合成其中 1,2,4-恶二唑部分取代 ONO3805 的酰胺键的化合物,并评估其作为潜在良性前列腺增生治疗靶点的 5α-还原酶抑制活性。四种 1,2,4-恶二唑衍生物 1、2、8 和 20 在体外针对大鼠肝微粒体的 5α-还原酶进行了评估。制备的 1 和 2 具有与 ONO3805 相似的结合亲和力 (Ki)。因此,使用 1,2,4-恶二唑环作为 ONO3805 中酰胺键的替代物在本研究中取得了成功。它不仅可以提高化学稳定性,还可以保持有意义的抑制活性。
