  3,4-Dihydroxychalcones as potent 5-lipoxygenase and cyclooxygenase inhibitors

  摘要：

  A novel series of 3,4-dihydroxychalcones was synthesized to evaluate their effects against 5-lipoxygenase and cyclooxygenase. Almost all compounds exhibited potent inhibitory effects on 5-lipoxygenase with antioxidative effects, and some also inhibited cyclooxygenase. The 2',5'-disubstituted 3,4-dihydroxychalcones with hydroxy or alkoxy groups exhibited optimal inhibition of cyclooxygenase. We found that 2',5'-dimethoxy-3,4-dihydroxychalcone (37; HX-0836) inhibited cyclooxygenase to the same degree as flufenamic acid and 6-lipoxygenase, more than quercetin. Finally, these active inhibitors of 5-lipoxygenase inhibited arachidonic acid-induced mouse ear edema more than phenidone.

  report a practical manganese-catalyzed enantio-differentiating hydroxylation of tertiary propargylic C–H bonds in acyclic systems, producing a wide range of structurally diverse enantioenriched tertiary propargyl alcohols in high efficiency with extremely efficient chemo- and enantio-discrimination. Other features include the use of C–H substrates as the limiting reagent, noteworthy functional group compatibility

  C(sp 3 )–H 键的直接位点选择性和对映选择性氧官能化形成具有一般范围、具有可预测选择性和制备有用产率的醇，代表了合成有机化学标准逻辑的范式转变。然而，对于用于对映体富集的叔醇合成的叔C-H键的酶促或非酶促不对称羟基化的了解非常缺乏。在这里，我们报道了无环体系中叔炔丙C-H键的实用锰催化对映差异化羟基化，以极其有效的化学和对映歧视的方式高效地产生了各种结构多样的对映体丰富的叔丙炔醇。其他特点包括使用 C-H 底物作为限制试剂、值得注意的官能团兼容性、出色的合成实用性和可扩展性。这些发现为开发具有挑战性的底物的金属催化不对称氧化提供了蓝图。
