  and consequently a number of compounds from this series demonstrated single-digit nanomolar 17β-HDS3 inhibitory activity in vitro. Subsequent optimization work in pursuit of the improvement of oral bioavailability demonstrated in vivo proof-of-concept by prodrug strategy based on phosphate esters for these 17β-HSD3 inhibitors. When a phosphate ester 16 was administered orally at a high dose of 100 mg/kg

  先前我们已经报道了衍生自亚苄基恶唑烷二酮和噻唑烷二酮支架的新型3类有效的17β-羟类固醇脱氢酶抑制剂（17β-HSD3）的发现。在这项研究中，这些类似物是在基于人类细胞的分析中进行设计，合成和评估的。建立了围绕该药效团的详细的结构-活性关系（SAR），因此，该系列化合物中的许多化合物在体外均表现出一位数的纳摩尔17β-HDS3抑制活性。为改善口服生物利用度而进行的后续优化工作已通过基于磷酸酯的前药策略针对这些17β-HSD3抑制剂进行了体内概念验证。当以100 mg / kg的高剂量口服磷酸酯16时，图16显示，在促黄体生成激素释放激素（LH-RH）诱导的T产生测定中，相对于阳性对照，有效的睾丸激素（T）降低作用大约两倍。给药后4小时，降低T的作用持续在对照的约10％水平。基于该系列的非甾体分子具有为治疗前列腺癌提供独特而有效的临床机会的潜力。

  is the production of hydrolytic β-lactamase enzymes. Nowadays, the combination of β-lactam antibiotics with β-lactamase inhibitors (BLIs) is the main strategy for overcoming such issues. Nevertheless, particularly challenging β-lactamases, such as OXA-48, pose the need for novel and effective treatments. Herein, we describe the screening of a proprietary compound collection against Klebsiella pneumoniae

  细菌对β-内酰胺类耐药的主要原因是产生水解β-内酰胺酶。如今，β-内酰胺类抗生素与β-内酰胺酶抑制剂（BLI）的组合是克服这些问题的主要策略。然而，特别具有挑战性的 β-内酰胺酶，如 OXA-48，需要新的和有效的治疗方法。在此，我们描述了针对肺炎克雷伯菌OXA-48的专有化合物集合的筛选，从而鉴定了几种化学型，如 4-ideneamino-4H-1,2,4-三唑 (SC_2) 和吡唑并 [3,4 -b] 吡啶 (SC_7) 核心作为潜在的抑制剂。重要的是，后者系列（ID2、AC 50= 0.99 μM) 通过可逆和竞争性作用机制抑制 OXA-48，如生化和 X 射线研究所示；此外，它略微提高了亚胺培南在大肠杆菌ATCC BAA-2523 β-内酰胺抗性菌株中的活性。此外，ID2显示出良好的溶解性，并且在最高测试浓度下没有毒性迹象，这为进一步优化程序以开发新型有效的非 β-内酰胺 BLI 提供了一个有希望的起点。
