  • Azasteroids: structure-activity relationships for inhibition of 5.alpha.-reductase and of androgen receptor binding

    In addition, 4-azasteroids with a D-homo ring or methyl substitution at C-7 (alpha and beta) or C-16 (alpha and beta) were prepared. The majority of the C-17 substituents were prepared from reactive intermediates derived from the 17 beta-COOH. Enhanced 5 alpha-reductase inhibition in both the human and rat enzyme assays is seen with 4-CN substitution on 3-oxo-delta 4 steroids and with a C-17 side
    制备了一系列类固醇,主要是4-氮杂类固醇,并在体外进行了测试,以作为人和大鼠前列腺5α-还原酶以及二氢睾丸激素与大鼠雄激素受体结合的抑制剂。主要的结构修饰是类固醇核的C-17位置的A环和连接部分的变化。新的A环修改包括碳环系列中的4-cyano-3-oxo-delta 4系统和1 alpha-CN,1 alpha-CH3、1 alpha,2 alpha-CH2、2 beta-F,2-aza, 3-oxo-4-aza系列中的2-oxa和A-homo变化。另外,制备了在C-7(α和β)或C-16(α和β)具有D-高环或甲基取代的4-氮杂甾类。大多数C-17取代基是由衍生自17β-COOH的反应性中间体制备的。在人和大鼠酶试验中,通过在3-oxo-delta 4类固醇上进行4-CN取代和在4-aza-3上结合了亲脂性取代的半极性基团的C-17侧链,可以看到增强的5α-还原酶抑制作用-oxo-5α

    Finasteride is a 5-α-reductase inhibitor with a steroidal skeleton and an amide group in its structure. It was subjected to forced degradation to observe its stability under stress conditions according to ICH guidelines. It was found to be stable to base and peroxide. However, in acid medium, three degradation products were observed. All of them were isolated from the reaction mixture by preparative HPLC. Their structures were elucidated by extensive analysis of 1D, 2D NMR spectra and HRMS. To best of our knowledge, none of them have been reported elsewhere.
    非那雄胺是一种 5-α 还原酶抑制剂,具有类固醇骨架,其结构中含有一个酰胺基团。根据 ICH 指南,对该药物进行了强制降解,以观察其在应力条件下的稳定性。结果发现它对碱和过氧化物稳定。不过,在酸性介质中,观察到了三种降解产物。制备型高效液相色谱法从反应混合物中分离出了所有这些降解产物。通过对一维、二维核磁共振波谱和 HRMS 进行广泛分析,阐明了它们的结构。据我们所知,其他地方尚未报道过它们。

    bonding for diverse C–X (X = C, N, O, S) cross-couplings with a low activation barrier. In situ characterization and quantum-theoretical studies show that such a dynamic process for cross-coupling is triggered by the adsorption of two different reactants at geminal metal sites, rendering homo-coupling unfeasible. These intrinsic advantages of GACs enable the assembly of heterocycles with several coordination
    单原子催化剂 (SAC) 具有明确的活性位点,使其在有机合成中具有潜在意义1,2,3,4。然而,由于空间环境和电子量子态的限制,这些稳定在固体载体上的单核金属物质的结构可能不是催化复杂分子转化的最佳选择5,6。在这里,我们报告了一类异质孪生原子催化剂(GAC),它以特​​定的配位和空间接近度配对单原子位点。在聚合氮化碳 (PCN) 主体中,规则分离的具有离域 π 键合性质的氮锚定基团7允许在高金属密度下以约 4 Å 的基态间隔配位铜孪生位点8。GAC 中各个 Cu 位点的适应性协调,通过动态 Cu-Cu 键合,实现了具有低活化势垒的多种 C-X (X = C、N、O、S) 交叉偶联的协作桥偶联途径。原位表征和量子理论研究表明,这种交叉偶联的动态过程是由两种不同反应物在偕金属位点的吸附引发的,使得同质偶联不可行。GAC 的这些内在优势使得能够组装具有多个配位位点的杂环、空间拥挤的支架和具有高
