transcription factor, hypoxia inducible factor (HIF), that mediates the hypoxic response in animals. Hydroxylation of HIF both causes its degradation and limits its activity. We describe how the use of structural data coupled to solid-phase synthesis led to the discovery of a selective inhibitor of one of the HIF hydroxylases. The inhibitor N-oxalyl-d-phenylalanine was shown to inhibit the HIF asparaginyl
一组四种非血红素铁 (II) 和 2-氧戊二酸依赖性酶催化转录因子、缺氧诱导因子 (HIF) 的翻译后修饰,该转录因子介导动物的缺氧反应。HIF 的羟基化会导致其降解并限制其活性。我们描述了如何使用与固相合成耦合的结构数据导致发现一种 HIF 羟化酶的选择性抑制剂。抑制剂 N-草酰-d-苯丙氨酸显示抑制 HIF 天冬酰胺酰羟化酶 (FIH) 但不抑制 HIF 脯氨酰羟化酶。与 FIH 复合的抑制剂的晶体结构表明它与 2OG 结合,并且很可能与分子氧结合位点结合。该结果将有助于调节缺氧反应,以上调具有生物医学重要性的特定基因,
