  Synthesis and in Vitro Evaluation of Two Progressive Series of Bifunctional Polyhydroxybenzamide Catechol-O-methyltransferase Inhibitors

  摘要：

  Two progressive series of molecules with two polyhydroxybenzamide substructures were synthesized and tested as potential inhibitors of catechol-O-methyltransferase (COMT). These compounds were designed for the purpose of enhanced enzyme binding with duplicated substructures separated by a linker section of various lengths. Our results show that potency and mode of inhibition observed with the ''bifunctional'' compounds were a reflection of their bifunctional nature. Furthermore, potency and mode of inhibition were dependent on the length of the linker section. Of the assayed compounds, the optimum linker was found to be diaminopropane. For example, N,N'-1,3-propanediylbis(3,4-dihydroxybenzamide) and N,N'-1,3-propanediylbis(3,4,5-trihydroxybenzamide) demonstrated strong inhibitory action against COMT, with apparent K-i values of 0.3 and 6.0 mu M, respectively.

  A mild, efficient and highly convenient protocol is reported for the synthesis of a series of polyphenolic amides using ferric exchanged montmorillonite as a strong solid acid catalyst. This heterogeneous catalyst has an advantage of a strikingly simple work up procedure over conventional homogeneous acids. The catalyst is recoverable and recyclable.

  报告采用铁交换蒙脱石作为强固酸催化剂，合成了一系列多酚酰胺，该方法温和、高效、操作简便。与传统的均相酸催化剂相比，这种异相催化剂的优点是操作过程非常简单。催化剂可回收和循环使用。
