    Identification of novel molecular scaffolds for the design of MMP-13 inhibitors: A first round of lead optimization
    摘要:
    Osteoarthritis (OA) is the leading cause of joint pain and disability in middle-aged and elderly patients, and is characterized by progressive loss of articular cartilage. Among the various matrix metalloproteinases (MMPs), MMP-13 is specifically expressed in the cartilage of human OA patients and is not present in normal adult cartilage. Thus. MMP-13-selective inhibitors are promising candidates in ostearthritis therapy. Recently, we designed an N-isopropoxy-arylsulfonamide-based hydroxamate inhibitor, which showed low nanomolar activity and high selectivity for MMP-13. In parallel to further studies aiming to assess the in vivo activity of our compound, we screened the Life Chemicals database through computational docking to seek for novel scaffolds as zinc-chelating non-hydroxamate inhibitors. Experimental evaluation of 20 selected candidate compounds verified five novel leads with IC50 in the low mu M range. These newly discovered inhibitors are structurally unrelated to the ones known so far and provide useful scaffolds to develop compounds with more desirable properties. Finally, a first round of structure-based optimization on lead 1 was accomplished and led to an increase in potency of more than 5 fold. (C) 2011 Elsevier Masson SAS. All rights reserved.

    摘要:
    在这项工作中,一系列新型香叶氧基和法尼氧基 3-乙酰香豆素的设计、合成和构效关系被报道为有效的大豆 15-脂氧合酶抑制剂。在制备的香豆素中,7-法呢基氧基-3-乙酰香豆素 ( 12b ) 被发现是最有效的抑制剂,IC 50 = 0.68 μM,而 3-乙酰香豆素 ( 10a和11a ) 5 位和 6 位的O-香叶基取代基则不是最有效的抑制剂。抑制剂。通过对接研究,考虑了合成化合物的结合亲和力和优选姿势。结果发现,脂氧合酶抑制活性与异戊烯基长度链直接相关。与其他衍生物相比,有效抑制剂12b的法尼基部分更有效地占据了酶的疏水空腔。此外,利用 7-法呢基氧基-3-乙酰基香豆素中法呢基链的这种姿势,乙酰基可以定向到活性位点中的亲水袋。

  • Synthesis and selective human monoamine oxidase inhibition of 3-carbonyl, 3-acyl, and 3-carboxyhydrazido coumarin derivatives

    Several 3-carbonyl (1–26), 3-acyl (27–52), and 3-carboxyhydrazido (53–58) coumarins have been synthesized in high yields (72–99%) and tested in vitro for their human monoamine oxidase A and B (hMAO-A and hMAO-B) inhibitory activity. Different substituents on the coumarin nucleus were evaluated for their effect on biological activity and isoform selectivity. Substitution at position C7 of the 3-ethyl

    Natural or synthetic coumarins showed gastroprotective and antiulcer activity in animal models. In this study, we have synthetized twenty coumarins using classic methods to evaluate their gastroprotective effects on the ethanol/HCl-induced gastric lesion model in mice at 20mg/kg. Among the coumarins synthetized, compounds 6 and 10 showed the greatest gastroprotective activity being as active as lansoprazole

    underscores the need to find new hDPP III inhibitors. In this research, five series of structurally different coumarin derivatives were studied to provide a relationship between their inhibitory profile toward hDPP III combining an in vitro assay with an in silico molecular modeling study. The experimental results showed that 26 of the 40 tested compounds exhibited hDPP III inhibitory activity at a concentration

    which a radical can act. Electrochemistry is a useful tool for this purpose. In this work, the cyclic voltammetry-based methodology was used to generate superoxide anion radical through oxygen one-electron reduction in a dimethyl sulfoxide solution. Plotting the remaining percentage of initial current against compound concentration we can establish a Reactivity Index (RI50), for comparative purpose
    本研究揭示了对合成香豆素的超氧化物自由基阴离子反应性。自由基在许多疾病中都起着重要作用,并且还具有保护功能。因此,我们必须保持其浓度平衡,这就是香豆素等外源抗氧化剂变得重要的地方。由于自由基可以发挥多种作用机理,因此有多种方法可以量化抗氧化剂的效率。电化学是用于此目的的有用工具。在这项工作中,使用基于循环伏安法的方法通过在二甲亚砜溶液中通过氧单电子还原生成超氧阴离子自由基。将剩余的初始电流百分比与化合物浓度作图,我们可以建立反应活性指数(RI 50),以作比较。该指数是指将初始峰值电流降低50%的浓度值。对电生成的超氧阴离子自由基反应性最高的香豆素是3-乙酰基-7,8-二羟基香豆素(7,8-香豆)。
