  Compounds are provided that bind allosterically to the catalytic domain of MMP-13 and comprise a hydrophobic group, first and second hydrogen bond acceptors and at least one, and preferably both, of a third hydrogen bond acceptor and a second hydrophobic group. Cartesian coordinates for centroids of the above features are defined in the specification. When the ligand binds to MMP-13, the first, second and third (when present) hydrogen bond acceptors bond respectively with Thr245, Thr 247 and Met 253, the first hydrophobic group locates within the S1′ channel of MMP-13 and the second hydrophobic group (when present) is relatively open to solvent. The compounds specifically inhibit the matrix metalloproteinase-13 enzyme and thus are useful for treating diseases resulting from tissue breakdown, such as heart disease, multiple sclerosis, arthritis, atherosclerosis, and osteoporosis.

  chemoselective alkylation, benzylation, and arylation of C-5 and C-6 substituted pyrimidine nucleobases selectively at the N-3 position. The reactions were found to proceed, with high efficiency, without the requirement of solvent and were complete within 10–15 min of irradiation. The efficiency of the method was further improved by addition of a Lewis acid, which not only increases the yield significantly but

  摘要 由于区域选择性和化学选择性较差，选择性合成 N-3 取代的嘧啶核碱基或嘧啶酮一直是一个挑战。在本文中，我们展示了选择性 N-3 取代的修饰嘧啶酮的一步、从头合成。我们开发了一种微波辅助方法，用于在 N-3 位置选择性地对 C-5 和 C-6 取代的嘧啶核碱基进行直接、化学选择性烷基化、苄基化和芳基化。发现反应以高效率进行，不需要溶剂，并在辐照后 10-15 分钟内完成。通过加入路易斯酸进一步提高了该方法的效率，不仅显着提高了产率，而且加快了反应速度。图形概要
