unmet medical need. De-repression of fetal hemoglobin in erythrocytes is a clinically validated approach for the management of sickle cell disease, but the only FDA-approved medicine for this purpose has limitations to its use. We conducted a phenotypic screen in human erythroid progenitor cells to identify molecules with the ability to de-repress fetal hemoglobin, which resulted in the identification
β-血红蛋白病(例如镰状细胞病)代表了全球主要的未满足医疗需求。抑制胎儿红血球中血红蛋白的含量是临床验证的治疗镰状细胞疾病的方法,但是唯一获得FDA批准的用于此目的的药物在使用中受到限制。我们在人类红系祖细胞中进行了表型筛选,以鉴定具有抑制胎儿血红蛋白抑制能力的分子,从而鉴定出含有苯并氧杂硼酸的命中化合物1。发现该化合物具有适度的细胞效价和铅样药代动力学,但没有可优化的可识别SAR。密切相关的类似物1的系统解构揭示了片段状羧酸12,然后对其进行优化以提供四唑31,与1相比,四唑31的细胞效能提高了约100倍,在大鼠中的口服暴露水平较高,并且具有出色的溶解度。
