structure-activity relationship (SAR) study around this scaffold with the aim to discover new selective FXIIa inhibitors with an improved physico-chemical profile. To better understand these SAR, docking experiments were undertaken. For this purpose, we built an original hybrid model of FXIIa. This model has the advantage to gather the best features from the recently published crystal structure of FXIIa
凝血因子XIIa(FXIIa)的抑制剂具有吸引力,可以详细说明该蛋白酶在止血和血栓形成中的作用,抑制凝血测定中由于接触途径激活而引起的假象,并且有望用作抗血栓治疗。先前已将3-羧酰胺香豆素描述为小分子量FXIIa抑制剂。在这项研究中,我们报告了围绕该支架的结构-活性关系(SAR)研究,目的是发现具有改进的理化特性的新型选择性FXIIa抑制剂。为了更好地理解这些SAR,进行了对接实验。为此,我们构建了FXIIa的原始混合模型。该模型的优点是可以从最近发布的FXIIa的酶原形式的晶体结构和更经典的同源性模型中收集最佳特征。
