Small‐molecule inhibitors of hypoxia‐inducible factor prolyl hydroxylases (HIF‐PHs) are currently under clinical development as novel treatment options for chronic kidney disease (CKD) associated anemia. Inhibition of HIF‐PH mimics hypoxia and leads to increased erythropoietin (EPO) expression and subsequently increased erythropoiesis. Herein we describe the discovery, synthesis, structure–activity relationship (SAR), and proposed binding mode of novel 2,4‐diheteroaryl‐1,2‐dihydro‐3H‐pyrazol‐3‐ones as orally bioavailable HIF‐PH inhibitors for the treatment of anemia. High‐throughput screening of our corporate compound library identified BAY‐908 as a promising hit. The lead optimization program then resulted in the identification of molidustat (BAY 85‐3934), a novel small‐molecule oral HIF‐PH inhibitor. Molidustat is currently being investigated in clinical phase III trials as molidustat sodium for the treatment of anemia in patients with CKD.

Molidustat (BAY 85-3934) 的发现:一种用于治疗肾性贫血的小分子口服 HIF-脯氨酰羟化酶 (HIF-PH) 抑制剂

缺氧诱导因子脯氨酰羟化酶(HIF-PH)的小分子抑制剂目前正在临床开发中,作为慢性肾病(CKD)相关贫血的新治疗选择。HIF-PH 的抑制模拟缺氧并导致促红细胞生成素 (EPO) 表达增加,从而增加红细胞生成。在此,我们描述了新型 2,4-二杂芳基-1,2-二氢-3 H-吡唑-3-酮类药物的发现、合成、结构-活性关系 (SAR) 和拟议的结合模式,作为口服生物可利用的 HIF- PH抑制剂贫血的治疗。对我们公司化合物库的高通量筛选确定 BAY-908 是一个有前景的热门产品。先导化合物优化计划最终鉴定出莫度司他 (BAY 85-3934),这是一种新型小分子口服 HIF-PH 抑制剂。Molidustat 目前正在临床 III 期试验中研究作为 molidustat 钠用于治疗 CKD 患者贫血。
