  Probing the active site of rat porphobilinogen synthase using newly developed inhibitors

  摘要：

  The structurally related tetrapyrrolic pigments are a group of natural products that participate in many of the fundamental biosynthetic and catabolic processes of living organisms. Porphobilinogen synthase catalyzes a rate-limiting step for the biosyntheses of tetrapyrrolic natural products. In the present study, a variety of new substrate analogs and reaction intermediate analogs were synthesized, which were used as probes for studying the active site of rat porphobilinogen synthase. The compounds 1, 3, 6, 9, 14, 16, and 28 were found to be competitive inhibitors of rat porphobilinogen synthase with inhibition constants ranging from 0.96 to 73.04 mM. Compounds 7, 10, 12, 13, 15, 17, 18, and 26 were found to be irreversible enzyme inhibitors. For irreversible inhibitors, loose-binding inhibitors were found to give stronger inactivation. The amino group and carboxyl group of the analogs were found to be important for their binding to the enzyme. This study increased our understanding of the active site of porphobilinogen synthase.

  A AuIII-catalyzed synthesis of α-halomethyl ketones from terminal alkynes was developed. This approach features excellent functional group compatibility and good yields for both aromatic and aliphatic terminal alkynes. The resulting α-halomethyl ketones were used to prepare heterocyclic indolizine structures. The plausible mechanism of the one-pot reaction is proposed.

  开发了一种 AuIII 催化的从末端炔烃合成 α-卤代甲基酮的方法。这种方法对芳香族和脂肪族末端炔烃具有优异的官能团兼容性和良好的产率。所得的α-卤代甲基酮用于制备杂环茚茚结构。提出了一锅反应的合理机制。
