  取代的γ-吡喃酮的便捷合成

  摘要：

  已经开发出一种有效且通用的合成方法，用于各种2-单-和2,6-二取代的γ-吡喃酮。该方法利用酰基氯3对β-甲氧基-α，β-烯酮烯醇酸锂4进行C-酰化（70-85％），然后将所得的烯醇5转化为γ-吡喃酮进行酸催化的环化（> 80％）。六

  D-type cyclin including D1, D2 and D3 are shown to be actively involved in the regulation of cardiomyocyte cell growth and proliferation. The levels of the various cyclins including the relative levels of these three cyclins have varying effects on the growth of cardiomyocytes. Type-D cyclin levels vary with response to various stimuli including injury effects D-type cyclin levels and localization within cardiomyocytes. Various methods, materials and systems for screening for candidate molecules that may effect D-type cyclin levels including molecules that may affect the expression, stability and/or subcellular location or other aspects of one or more of the cyclin D proteins are described. Various types of molecules including RNAi, small molecules, proteins, nucleic acids, and the like can be screened to identify candidate molecules.
