Phosphoinositide 3-kinase δ (PI3Kδ), a member of the class I PI3K family, is an essential signaling biomolecule that regulates the differentiation, proliferation, migration, and survival of immune cells. The overactivity of this protein causes cellular dysfunctions in many human disorders, for example, inflammatory and autoimmune diseases, including asthma or chronic obstructive pulmonary disease (COPD)
磷酸肌醇 3-激酶δ (PI3K δ ) 是 I 类 PI3K 家族的成员,是调节免疫细胞分化、增殖、迁移和存活的重要信号生物分子。这种蛋白质的过度活性会导致许多人类疾病的细胞功能障碍,例如炎症和自身免疫性疾病,包括哮喘或慢性阻塞性肺病 (COPD)。在这项工作中,我们设计并合成了一个新的基于吲哚-4-基-吡唑并[1,5- a ]嘧啶的小分子抑制剂库,IC 50值在低纳摩尔范围内,对 PI3K δ异构体具有高选择性. CPL302253 ( 54) 是所获得的所有结构中最有效的化合物,IC 50 = 2.8 nM,是未来临床开发用于预防哮喘的吸入药物的潜在候选药物。
