  Discovery of furan and dihydrofuran-fused tricyclic benzo[ d ]imidazole derivatives as potent and orally efficacious microsomal prostaglandin E synthase-1 (mPGES-1) inhibitors: Part-1

  摘要：

  This letter describes the synthesis and biological evaluation of furan and dihydrofuran-fused tricyclic benzo[d]imidazole derivatives as novel mPGES-1 inhibitors, capable of inhibiting an increased PGE(2) production in the disease state. Structure-activity optimization afforded many potent mPGES-1 inhibitors having <50 nM potencies in the A549 cellular assay and adequate metabolic stability in liver microsomes. Lead compounds 8l and 8m demonstrated reasonable in vitro pharmacology and pharmacokinetic properties over other compounds. In particular, 8m revealed satisfactory oral pharmacokinetics and bioavailability in multiple species like rat, guinea pig, dog and cynomolgus monkey. In addition, the representative compound 8m showed in vivo efficacy by inhibiting LPS-induced thermal hyperalgesia with an ED50 of 14.3 mg/kg in guinea pig. (C) 2017 Elsevier Ltd.

  氟化唑类抗结核药物的设计、合成和药理学评价

  摘要：

  描述了作为抗结核药物的 2,2-二甲基-2,3-二氢苯并呋喃系留 1,3,4-恶二唑衍生物的设计、合成和生物筛选。目标化合物的合成通过一系列反应方案进行。所有合成的化合物均通过IR、1H NMR、13C NMR和质谱进行表征。分子对接研究证实了合成化合物的治疗潜力。在合成的化合物中，发现 12a、12c、12d、12e、12g 和 12j 在体外和体外对非复制性结核分枝杆菌 H37Ra 的复制培养物比对复制培养物更有活性。这些化合物的最低抑菌浓度 (MIC) 值在 2.31–23.91 μg/mL 范围内。针对细胞系 THP-1、A549 和 PANC-1 进行细胞毒性研究，并且观察到这些化合物对宿主细胞无毒。用 InhA (FabI/ENR) 进行分子对接，并表明合成化合物的抗分枝杆菌潜力。发现这里提出的调查对于开发针对分枝杆菌感染的新治疗剂是偶然的。

  In an effort to identify CYP and hERG clean mPGES-1 inhibitors from the dihydrofuran-fused tricyclic benzo[d] imidazole series lead 7, an extensive structure-activity relationship (SAR) studies were performed. Optimization of A, D and E-rings in 7 afforded many potent compounds with human whole blood potency in the range of 160-950 nM. Selected inhibitors 21d, 21j, 21m, 21n, 21p and 22b provided selectivity against COX-enzymes and mPGES-1 isoforms (mPGES-2 and cPGES) along with sufficient selectivity against prostanoid synthases. Most of the tested analogs demonstrated required metabolic stability in liver microsomes, low hERG and CYP liability. Oral pharmacokinetics and bioavailability of lead compounds 21j, 21m and 21p are discussed in multiple species like rat, guinea pig, dog, and cynomolgus monkey. Besides, these compounds revealed low to moderate activity against human pregnane X receptor (hPXR). The selected lead 21j further demonstrated in vivo efficacy in acute hyperalgesia (ED50: 39.6 mg/kg) and MIA-induced osteoarthritic pain models (ED50: 106 mg/kg). (C) 2018 Elsevier Ltd.
