  新的基于α-取代的琥珀酸酯的异羟肟酸作为TNFα转化酶抑制剂。

  摘要：

  肿瘤坏死因子α转化酶（TACE）是负责将前TNFα转化为TNFα的酶，据报道是与基质金属蛋白酶（MMP）密切相关的金属蛋白酶。目前的TACE抑制剂，例如基于Marimastat（TACE IC（50）：3.8 nM;血液IC（50）：7 microM）和BB1101（TACE IC（50）：0.2 nM;血液IC（50）的琥珀酸异羟肟酸） ：2.3 microM）在血液中具有中等效力且体内特性较差。研究了将新的大体积α-取代基引入这些基于琥珀酸酯的异羟肟酸中。与Marimastat相比，诸如硫醚，磺酰胺和醚等取代物对TACE的效力有所改善。尽管这种改善并未转化为硫醚或醚取代基的更好的血液效力，与Marimastat相比，磺酰胺系列药物对TACE和血液的功效均得到改善。该磺酰胺系列的优化最终确定了杂环双环磺酰胺，例如3t（TACE IC（50）：0.57 nM；血液IC（50）：0.28 microM）。

  Inhibition of Matrix Metalloproteinases by Hydroxamates Containing Heteroatom-Based Modifications of the P1' Group

  摘要：

  In this study, structure-based drug design of matrix metalloproteinase inhibitors [human fibroblast collagenase (HFC), human fibroblast stromelysin (HFS), and human neutrophil collagenase (HNC)] was utilized in the development of potent hydroxamates which contain novel, heteroatom-based modifications of the P-1' group. A series containing a P-1' butyramide group resulted in a nanomolar potent and selective HNC inhibitor as well as a dual HFS/HNC inhibitor. Benzylic others with a four- or five-carbon methylene linker in the P-1' position also produced nanomolar potent HFS/HNC inhibition and micromolar potent HFC inhibition as expected. Surprisingly, the phenolic ethers of the same overall length as the benzylic ethers showed nanomolar potencies against HFC, as well as HFS and HNC. The potency profile of the phenolic ethers was optimized by structure-activity relationships of the phenolic group and the C-terminal amide. These inhibitors may help elucidate the in vivo roles of matrix metalloproteinases in normal and disease states.

Current inhibitors of TACE such as succinate-based hydroxamic acids exemplified by Marimastat (TACE IC(50): 3.8 nM; blood IC(50): 7 microM) and BB1101 (TACE IC(50): 0.2 nM; blood IC(50): 2.3 microM) suffer from modest potency in blood and poor in vivo properties.
