identification of oral small-molecule inhibitors of FXa remains a research focus. On the basis of the X-ray crystal structure of FXa and its inhibitor rivaroxaban, we designed and synthesized a series of conformationally restricted mimics containing a novel [6,6,5] tricyclic fused oxazolidinone scaffold. Intensive structure–activity relationship (SAR) and structure–pharmacokinetic relationship (SPR) studies
凝血酶Xa因子(FXa)是抗凝治疗的一个特别有希望的目标,而口服FXa小分子抑制剂的鉴定仍然是研究的重点。基于FXa及其抑制剂利伐沙班的X射线晶体结构,我们设计并合成了一系列构象受限的模拟物,其中包含新型[6,6,5]三环稠合恶唑烷酮骨架。对这个新系列的密集结构-活性关系(SAR)和结构-药代动力学关系(SPR)的研究导致发现化合物11a:一种高效,选择性,直接和口服可生物利用的FXa抑制剂,具有出色的体内抗血栓形成功效,因此是优选的药代动力学概况。化合物11a的可药性评价被接受并带来了积极的成果。所有结果表明,化合物11a是用于预防和治疗静脉和动脉系统中血栓栓塞性疾病的有前途的候选药物。
