  • Allylic Oxidations Catalyzed by Dirhodium Caprolactamate via Aqueous <i>tert</i>-Butyl Hydroperoxide: The Role of the <i>tert</i>-Butylperoxy Radical
    作者:Emily C. McLaughlin、Hojae Choi、Kan Wang、Grace Chiou、Michael P. Doyle

    日期:2009.1.16
    These oxidation reactions occur with aqueous tert-butyl hydroperoxide (TBHP) without rapid hydrolysis of the caprolactamate ligands on dirhodium. Allylic oxidations of enones yield the corresponding enedione in moderate to high yields, and applications include allylic oxidations of steroidal enones. Although methylene oxidation to a ketone is more effective, methyl oxidation to a carboxylic acid can
    Dirhodium (II) 己内酰胺在生成叔丁基过氧自由基方面表现出最佳效率,叔丁基过氧自由基是氢原子提取的选择性试剂。这些氧化反应发生在叔水溶液中-丁基氢过氧化物 (TBHP) 没有快速水解二铑上的己内酰胺配体。烯酮的烯丙基氧化以中等至高产率产生相应的烯二酮,其应用包括甾体烯酮的烯丙基氧化。虽然亚甲基氧化成酮更有效,但也可以实现甲基氧化成羧酸。在与其他金属催化剂的比较研究中描述了己内酰胺二铑 (II) 作为 TBHP 烯丙基氧化的催化剂的优越效率(催化剂的摩尔%,转化率)。不同的催化剂以相同的相对产率产生基本上相同的产物混合物表明催化剂不参与产物形成步骤。烯酮烯丙基氧化研究产生的机理影响为控制产物形成的因素提供了新的见解。以前未公开的歧化途径,由已发现混合过氧化物的叔丁氧基自由基,用于通过烯丙基氧化形成酮产物。

    公开(公告)日:2009-04-09
    The present invention relates to compositions and methods for achieving the efficient allylic oxidation of organic molecules, especially olefins and steroids, under aqueous conditions. The invention concerns the use of dirhodium (II,II) “paddlewheel complexes, and in particular, dirhodium carboximate and tert-butyl hydroperoxide as catalysts for the reaction. The use of aqueous conditions is particularly advantageous in the allylic oxidation of 7-keto steroids, which could not be effectively oxidized using anhydrous methods, and in extending allylic oxidation to enamides and enol ethers.

    The present invention comprises compositions and methods for treating a tumor or neoplastic disease in a host, The methods employ conjugates comprising superantigen polypeptides, nucleic acids with other structures that preferentially bind to tumor cells and are capable of inducing apoptosis. Also provided are superantigen-glycolipid conjugates and vesicles that are loaded onto antigen presenting cells to activate both T cells and NKT cells. Cell-based vaccines comprise tumor cells engineered to express a superantigen along with glycolipids products which, when expressed, render the cells capable of eliciting an effective anti-tumor immune response in a mammal into which these cells are introduced. Included among these compositions are tumor cells, hybrid cells of tumor cells and accessory cells, preferably dendritic cells. Also provided are tumoricidal T cells and NKT cells devoid of inhitory receptors or inhibitory signaling motifs which are hyperresponsive to the the above compositions and lipid-based tumor associated antigens that can be administered for adoptive immunotherapy of cancer and infectious diseases.

  • Method for the diagnostic determination of the risk caused by an altered oxidative balance
    申请人:H&D S.R.L.
    公开号:US10345318B2
    公开(公告)日:2019-07-09
    A method is described for the diagnostic determination of the risk caused by an altered oxidative balance, comprising the photometric measurement of total cholesterol, hydroperoxides, and antioxidant capacity, on the basis of which the protective index, the oxidative index and the risk index caused by an altered oxidative balance (or ‘OBRI’) are calculated. This latter index has proved to be particularly dependable and reliable in determining the status of the oxidative balance in relation to cholesterol levels, being highly predictive of cardiovascular risk.

    Diagnostic tests for characterizing an individual's risk of developing or having a cardiovascular disease. In one embodiment the present diagnostic test comprises determining the level of myeloperoxidase (MPO) activity in a bodily sample obtained from the individual or test subject. In another embodiment, the diagnostic test comprises determining the level of MPO mass in a bodily sample obtained from the test subject. In another embodiment, the diagnostic test comprises determining the level of one or more select MPO-generated oxidation products in a bodily sample obtained from the test subject. The select MPO-generated oxidation products are dityrosine, nitrotyrosine, methionine sulphoxide or an MPO-generated lipid peroxidation products. Levels of MPO activity, MPO mass, or the select MPO-generated oxidation product in bodily samples from the test subject are then compared to a predetermined value that is derived from measurements of MPO activity, MPO mass, or the select MPO-generated oxidation product in comparable bodily samples obtained from the general population or a select population of human subjects. Such comparison characterizes the test subject's risk of developing CVD.
    用于确定个人罹患或患有心血管疾病风险的诊断测试。在一个实施方案中,本诊断测试包括确定从个体或测试对象处获取的身体样本中髓过氧化物酶(MPO)活性的水平。在另一个实施方案中,诊断检测包括确定从测试对象处获取的身体样本中 MPO 质量的水平。在另一个实施方案中,诊断检测包括确定从测试对象处获取的身体样本中一种或多种选择性 MPO 生成的氧化产物的水平。选择性 MPO 生成的氧化产物是指二酪氨酸、硝基酪氨酸、蛋氨酸亚砜或 MPO 生成的脂质过氧化产物。然后,将测试对象身体样本中的 MPO 活性、MPO 质量或所选 MPO 生成的氧化产物的水平与一个预定值进行比较,该预定值是通过测量从普通人群或特定人群中获得的可比身体样本中的 MPO 活性、MPO 质量或所选 MPO 生成的氧化产物而得出的。通过这种比较可以确定受试者患心血管疾病的风险。
