essential target correlated to the occurrence and development of acute myeloid leukemia (AML). Herein, we investigated the pyrazolo[3,4-d]pyrimidine derivatives as potent and selective PI3Kδ inhibitors with high therapeutic efficacy toward AML. There were 44 compounds designed and prepared in a four-round optimization, and the biological evaluation showed that (S)-36 exhibited potent PI3Kδ inhibitory activity
PI3Kδ是与急性髓系白血病(AML)发生、发展相关的重要靶点。在此,我们研究了吡唑并[3,4- d ]嘧啶衍生物作为有效且选择性的PI3Kδ抑制剂,对AML具有较高的治疗效果。经过四轮优化设计制备了44个化合物,生物学评价表明( S )-36对MV-4-11和MOLM-13细胞表现出强效的PI3Kδ抑制活性、高选择性和高抗增殖活性。加上高口服生物利用度( F = 59.6%)。在MOLM-13皮下异种移植模型中, ( S )-36口服剂量10 mg/kg即可显着抑制肿瘤进展,TGI为67.81%,且无明显毒性。从机制上讲, ( S )-36可以强力抑制 PI3K/AKT 通路,从而在体外和体内显着抑制细胞增殖并显着诱导细胞凋亡。因此,化合物( S )-36代表了一种有前途的PI3Kδ抑制剂,用于高效治疗急性髓系白血病。
