Janus kinase 2 (JAK2) plays an essential role in the signaling of hormone-like cytokines and growth factors, which has been convinced as an important target of myeloproliferative neoplasms (MPNs) therapy. In this study, a series of novel pyrrolo[2,3-d]pyrimidine-phenylamide hybrids were designed and synthesized as potential JAK2 inhibitors through hybridization strategy. In vitro biological studies
Janus激酶2(JAK2)在激素样细胞因子和生长因子的信号转导中起重要作用,已被认为是骨髓增生性肿瘤(MPNs)治疗的重要靶标。在这项研究中,设计了一系列新型的吡咯并[2,3 - d ]嘧啶-苯酰胺杂化物,并通过杂交策略合成为潜在的JAK2抑制剂。体外生物学研究表明,这些化合物大多数都表现出对JAK2的有效活性。尤其是,化合物16c被确定为合适的先导化合物,在大鼠中表现出良好的药代动力学特征(F = 73.57%),在体外对红白血病细胞的疗效极佳(TF-1,IC 50 = 0.14μM),并且对JAK2的选择性高(我知道了50 = 6 nM,相对于JAK3的选择性> 97倍)。
