The discovery of novel 4-hydroxy-2-(heterocyclic)pyrimidine-5-carboxamide inhibitors of hypoxia-inducible factor (HIF) prolyl hydroxylases (PHD) is described. These are potent, selective, orally bioavailable across several species, and active in stimulating erythropoiesis. Mouse and rat studies showed hematological changes with elevations of plasma EPO and circulating reticulocytes following single
描述了新型的缺氧诱导因子(HIF)脯氨酰羟化酶(PHD)的4-羟基-2-(杂环)嘧啶-5-羧酰胺抑制剂的发现。这些在多个物种中均有效,选择性,口服生物利用,并在刺激促红细胞生成中起作用。小鼠和大鼠研究表明,单次口服给药后,血浆血浆EPO和循环网织红细胞升高会引起血液学变化,而大鼠连续4天qd po给药后血红蛋白水平升高。优化过程的主要重点是减少早期化合物在较高物种中观察到的长半衰期。这些努力导致了28(MK-8617)的鉴定,该鉴定已用于贫血的人类临床试验。
