  Synthesis of novel monocarbonyl curcuminoids, evaluation of their efficacy against MRSA, including ex vivo infection model and their mechanistic studies

  摘要：

  In continuation of our effort to improve the physiological stability and the antibacterial activity of curcuminoids against drug-resistant bacteria, a series of novel monocarbonyl curcuminoids were synthesized and screened for antibacterial activity against S. aureus and E. coli strains. These curcuminoids showed potent antibacterial activity against both methicillin-sensitive and methicillin-resistant strains of S. aureus with MIC values 2-8 and 4-16 mu g/mL, respectively. They also exhibited moderate potency against E. coll. strains. The four most active curcuminoids (7d, 7i, 7m, and 7p) were on further investigation found to be very stable under physiological conditions, non-hemolytic, and non-toxic toward mammalian cells up to 150 mu g/mL concentration. Mechanistic studies revealed that these curcuminoids displayed potent bactericidal activity by targeting cell membranes. Further, in an ex vivo mammalian co-culture infection model study, remarkably, the curcuminoids 7i and 7p were able to clear the internalized bacteria in mammalian cells and the activity was found to be superior to conventional antibiotics such as vancomycin and linezolid. Therefore, the present study affords us water-soluble, stable, non-toxic curcuminoids that may serve as lead molecules for development as antibacterial agents against MRSA infections.

  以 2,2-二甲基苯并吡喃作为具有抗血管生成潜力的 HIF-1 抑制剂的新型查耳酮衍生物的设计、合成和评价

  摘要：

  缺氧诱导因子-1 (HIF-1) 作为肿瘤转移、血管生成和患者预后不良的关键介质，已被公认为重要的抗癌药物靶点。到目前为止，一些具有不同骨骼结构的 HIF-1 抑制剂被报道为抗癌剂，主要是天然产物衍生的化合物。在这项研究中，我们利用组合原理选择苯并吡喃和查尔酮类天然产物，设计并合成了一系列与 2,2-二甲基苯并吡喃相关的查尔酮类化合物。一系列基于查尔酮的新型化合物与 2,2-二甲基苯并吡喃被评估为 HIF-1 抑制剂。HRE 荧光素酶报告基因测定证明化合物显示出优异的 HIF-1 抑制活性。其中，化合物16e表现出最好的特性：最强的HIF-1抑制活性（IC50  = 2.38 μM，比LXH-SYP-7高 3 倍）。同时，它还在无毒浓度下显着抑制 A549 细胞的迁移和 VEGF 诱导的侵袭。此外，管形成试验证明了其抗血管生成活性。此外，体内研究表明，化合物16e在matrigel plug

Besides, western blot analysis indicated that compound 53 was a potent down-regulator of inducible nitric oxide synthase (iNOS) protein. Docking study revealed that compound 53 also can dock into the active site of iNOS. Furthermore, at the dose of 10 mg/kg/day, compound 53 could both significantly suppress
