selective, direct coagulation factor Xa (FXa) inhibitor with excellent antithrombotic activity and improved solubility, a series of novel 3,4-diaminobenzoyl derivatives were designed and synthesized based on reported structure–activity relationship analysis of FXa inhibitors. Preliminary solubility test showed that the decrease of intramolecular hydrogen bonds and the change of rigid structure could effectively
为了获得具有优异的抗血栓形成活性和改善的溶解度的高选择性,直接凝血因子Xa(FXa)抑制剂,根据已报道的FXa抑制剂的结构-活性关系分析,设计并合成了一系列新颖的3,4-二氨基苯甲酰基衍生物。初步的溶解度试验表明,分子内氢键的减少和刚性结构的改变可以有效地改善化合物的理化性质。与阿哌沙班相比,浓度为40 nM时,合成的化合物7ab可以显着延长凝血酶原时间。7ab的对接调查FXa蛋白的序列分析表明,这几个基团可以与氨基酸残基ALA-190,ASP-189和GLY-216形成多个氢键。这些结果表明化合物7ab可以用作潜在的抗凝剂。
