  钌烯基膦-恶唑啉-钌配合物催化α-取代丙烯酸的不对称加氢

  摘要：

  在5 bar H 2下，使用RuPHOX-Ru作为手性催化剂，对各种α-取代的丙烯酸进行不对称氢化，从而以高达99％的收率和99.9％ee的产率提供相应的手性α-取代的丙酸。该反应可以以克级进行，具有相对较低的催化剂负载量（最高5000 S / C），所得产物（97％，99.3％ee）可用作构建生物活性手性分子的关键中间体。该不对称方案已成功应用于二氢青蒿酸的不对称合成，这是抗疟疾药物青蒿素工业合成所需的关键中间体。

  The enantioselective hydrolysis of 17 racemic α-substituted arylacetonitriles by Rhodococcus sp. CGMCC 0497 is described. The corresponding (R)-amides and (S)-acids were obtained with excellent enantiomeric excess in most cases. The effect of steric and electronic factors on the outcome of the reactions are discussed here. The results prove that nitrile-converting enzymes are efficient tools for the

  Objectives: Neuromuscular electrical stimulation (NMES) is widely used for improving muscle strength by simultaneous contraction in the prevention of muscle atrophy. Although there exist many clinical methods for evaluating the therapeutic response of muscles, Tc-99m-sestamibi which is a skeletal muscle perfusion and metabolism agent has not previously been used for this purpose. The aim of our work was to ascertain whether Tc-99m-sestamibi muscle scintigraphy is useful in the monitoring of therapeutic response to NMES in healthy women.Methods: The study included 16 women aged between 21 and 45, with a mean age of 32.7 +/- 6.4. Both quadriceps femoris muscles (QFM) of each patient were studied. After randomization to remove the effect of the dominant side, one QFM of each patient was subjected to the NMES procedure for a period of 20 days. NMES was performed with an alternating biphasic rectangular current, from a computed electrical stimulator daily for 23 minutes. After measurement of skinfold thickness over the thigh, pre- and post-NMES girth measurements were assessed in centimeters. Sixty minutes after injections of 555 MBq Tc-99m-sestamibi, static images of the thigh were obtained for 5 minutes. The thigh-to-knee uptake ratio was calculated by semiquantitative analysis and normalized to body surface area (NUR = normalized uptake ratio).Results: The difference between the pre and post NMES NUR values was Significant (1.76 +/- 0.31 versus 2.25 +/- 0.38, p = 0.0000). The percentage (%) increase in NUR values also well correlated with the % increase in thigh girth measurements (r = 0.89, p = 0.0000).Conclusion: These results indicated that Tc-99m-sestamibi muscle scintigraphy as a new tool may be useful in evaluating therapeutic response to NMES.
