describe our efforts to identify new PI3Kδ inhibitors following an “inhalation by design” strategy. Starting from the identification of a purine scaffold, we carried out a preliminary SAR expansion which led to the identification of a new hit characterized by a high enzymatic potency and moderate PI3Kδ selectivity. A subsequent optimization led to novel purine based derivatives with favorable in vitro ADME
PI3Kδ 是一种脂质激酶,在气道炎症中起着关键作用。因此,抑制 PI3Kδ 可被认为是治疗慢性呼吸系统疾病如哮喘和慢性阻塞性肺病 (COPD) 的一种有价值的策略。在这项工作中,我们描述了我们按照“设计吸入”策略确定新的 PI3Kδ 抑制剂的努力。从嘌呤支架的鉴定开始,我们进行了初步的 SAR 扩展,从而鉴定了一种新的命中物,其特点是具有高酶促效力和适度的 PI3Kδ 选择性。随后的优化导致新型嘌呤衍生物具有良好的体外ADME 特征,这可能代表未来开发新型吸入候选药物的有希望的起点。
