to be a metalloproteinase closely related to matrix metalloproteinases (MMPs). 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. The introduction of new bulky alpha-substituents into these
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)。
