  Synthesis and Biological Evaluation of a Novel Series of “Ortho-Nitrated” Inhibitors of Catechol-O-methyltransferase

  摘要：

  Novel regioisomeric "ortho-nitrated" catechols related to the catechol-O-methyltransferase (COMT) inhibitors BIA 3-202 3 and BIA 3-335 4 were synthesized and biologically evaluated. Changing the position of the nitro group from the "classical" meta- to the ortho-position relative to the side-chain substituent of the nitrocatechol pharmacophore exerted profound effects on selectivity and duration of COMT inhibition. Alkylaryl compounds 7a-d possessed shorter duration of action than their regioisomers, but 7b displayed reversed selectivity over 3 at 3 and 6 h, exhibiting preferential central inhibition. In the amino-substituted series, ortho-nitrated regioisomer 14k was less peripherally selective than 4 and short-acting, whereas decahydroquinoline 14g displayed an unprecedented combination of long-acting and selective peripheral inhibition. 7b could provide a useful tool to probe the pharmacological utility of short-acting, centrally selective COMT inhibitors in the treatment of depression in Parkinsonian patients, and 14g represents a promising candidate for clinical evaluation as an adjunct to L-Dopa therapy.

  噻唑衍生物在体外和体内作为环氧合酶抑制剂。

  摘要：

  环氧合酶（COXs）是重要的膜结合血红素酶，对血小板活化和炎症很重要。COX-1在大多数细胞中组成性表达，而COX-2是在炎症条件下高表达的诱导型亚型。已经进行了研究以评价噻唑衍生物作为抗炎分子。在这项研究中，我们研究了两种新型噻唑衍生物化合物1（N- [4-（4-羟基-3-甲氧基苯基）-1,3-噻唑-2-基]乙酰胺）和化合物的体外和体内作用2（4-（2-氨基-1,3-噻唑-4-基）-2-甲氧基苯酚）对炎症环境中前列腺素E2（PGE2）的产生和COX活性的影响。我们的结果表明，化合物1（IC50 9.01±0.01µM）和化合物2（IC50 11.65±6.20µM）（Mean±SEM）对COX-2依赖性PGE2的产生均具有有效抑制作用。我们还确定了COX-1活性是否被抑制。使用稳定过量表达COX-1和人血小板的细胞，我们显示化合物1是具有CO50（5.56×10（-8）±2.26×10（-8）µM）的COX-1特异性抑制剂。

  A homologous series of novel nitro-catechol structures (7a-7e) were synthesized and tested as inhibitors of the enzyme catechol-O-methyltransferase (COMT). Increasing chain length was found to have significant impact on both brain penetration and duration of COMT inhibition in the rat. Of this series, compound 7b (1-(3,4-dihydroxy-5-nitrophenyl)-2-phenyl-ethanone) was found to exhibit the most potent and selective inhibition of peripheral COMT, with an inhibition profile more similar to entacapone 2 than tolcapone 1 (an equipotent peripheral and central inhibitor) but with much improved duration of action (7b, 70% inhibition and 2, 25% inhibition at 9 h after administration). The effects of structural modifications to 7b on COMT inhibitory profile were investigated, and it is concluded that the carbonyl group and preferably unsubstituted aromatic ring are essential features to maintain prolonged peripheral COMT inhibition. The introduction of the alpha-methylene group, the major structural difference between 7b and 1, would appear responsible for the observed enhancement in selectivity of peripheral COMT inhibition of 7b, which has more limited access to the brain than 1.
