    Novel Tetrazole-Containing Analogues of Itraconazole as Potent Antiangiogenic Agents with Reduced Cytochrome P450 3A4 Inhibition
    摘要:
    Itraconazole has been found to possess potent antiangiogenic activity, exhibiting promising antitumor activity in several human clinical studies. The wider use of itraconazole in the treatment of cancer, however, has been limited by its potent inhibition of the drug metabolizing enzyme cytochrome P450 3A4 (CYP3A4). In an effort to eliminate the CYP3A4 inhibition while retaining its antiangiogenic activity, we designed and synthesized a series of derivatives in which the 1,2,4-triazole ring is replaced with various azoles and nonazoles. Among these analogues, 15n with tetrazole in place of 1,2,4-triazole exhibited optimal inhibition of human umbilical vein endothelial cell proliferation with an IC50 of 73 nM without a significant effect on CYP3A4 (EC50 > 20 mu M). Similar to itraconazole, 15n induced Niemann-Pick C phenotype (NPC phenotype) and blocked AMPK/mechanistic target of rapamycin signaling. These results suggest that 15n is a promising angiogenesis inhibitor that can be used in combination with most other known anticancer drugs.

    常规和微波促进芳基(烷基)唑肟的合成、E/Z 异构体比的 1H-NMR 光谱测定和 HOMO-LUMO 分析
    摘要:
    本研究采用常规方法和微波辐射法合成了12种肟衍生物。目的是比较常规方法和微波方法的有效性。两种方法都测定了它们的产率,当使用微波方法时产率增加。含有肟的化合物由于具有碳氮双键而表现出几何异构现象。因此,我们还旨在在本研究中评估它们的E / Z异构体比率。虽然在两种合成方法中合成的吡唑衍生物化合物大多以Z异构体形式获得,但观察到一些标题化合物几乎完全以E形式获得采用常规合成方法合成咪唑衍生物时的异构体。合成化合物的结构经IR、1 H- NMR、13 C- NMR和HRMS谱确证。此外,在本研究中,12 种肟衍生物的E/Z异构体的 HOMO-LUMO 能量和热力学性质使用 6-31 * G 基组和密度泛函理论 (DFT) 计算使用 B3LYP 方法进行了三种不同的计算。环境(水、乙醇、真空)。此外,还有化学硬度(η)、化学势(μ)、亲电指数(ω)、化学柔软度(σ )等几何参数) 是根据计算的 HOMO-LUMO

    手性 β-杂芳基氨基醇作为中间体在许多生物活性药物的合成中发挥着至关重要的作用,包括西诺贝酯、奥替康唑和咪康唑。然而,缺乏文献记录建立合成β-杂芳基氨基醇和上述药物的通用方法。在这项研究中,我们使用两种具有相反立体选择性的工程酮还原酶(KRED)成功不对称合成了 50 对手性 β-杂芳基氨基醇。基于这一成果,我们开发了一种三步化学酶级联路线,用于从市售的 2-溴苯乙酮衍生物合成手性咪康唑类似物。通过优化第一步合成α-咪唑基酮的溶剂,然后在第二步中使用KREDs还原α-咪唑基酮,并在第三步中进行醚化,我们获得了20种具有良好产率的手性咪康唑类似物(26 –84%)和令人印象深刻的立体选择性(高达 >99% ee)。值得注意的是,该路线无需分离酮和醇中间体,并避免在手性咪康唑类似物的合成中使用金属催化剂。此外,我们成功放大了( S )-咪康唑的制备,实现了30%的分离收率和>99% ee。该方
  • Synthesis and antifungal activity of a series of novel 1,2-disubstituted propenones

    DOI:10.1021/jm00391a037
    日期:1987.8
    To find an antifungal agent other than those of the imidazole and triazole series, a new class of 1,2-disubstituted propenones I and II was prepared and tested for antifungal activity. Comparison of the structure-activity relationships showed that the conjugated structure of carbonyl and exomethylene groups in I and II plays an important role in potent antifungal activity. However, it is noteworthy that compounds 53, 54, and 56, which have a hydroxymethyl or methoxymethyl group instead of an exo-methylene group in I, also showed potent activity. Although many compounds exhibited strong antifungal activity in vitro, none showed activity in vivo of oral efficacy against subacute systemic candidiasis in mice.
