α-Human thrombin is a potent platelet agonist involved in the blood coagulation cascade and is an attractive target for an anticoagulant agent due to its involvement in several debilitating diseases. In this contribution we present attempts to develop a new architecture for size-selective serine protease inhibitors that utilize a fully methylated icosahedral p-carborane as a dominating hydrophobic pharmacophore. Using a computational docking program, flexX, a carborane-containing inhibitor was designed and synthesized. Computationally, this compound displayed the ability to provide ligand-protein binding interactions throughout the thrombin’s main active site (S1-S3), while positioning an acylating group for facile irreversible attack at the Ser195 hydroxyl group.
δ±-人凝血酶是一种参与血液凝固级联的强效血小板激动剂,由于它与多种衰弱性疾病有关,因此是抗凝血剂的一个有吸引力的靶点。在这篇论文中,我们尝试开发一种新结构的尺寸选择性丝氨酸蛋白酶抑制剂,这种抑制剂利用完全甲基化的二十面体对硼烷作为主要的疏水性药理。利用计算对接程序 flexX,设计并合成了一种含碳硼烷的抑制剂。通过计算,这种化合物显示出了在凝血酶的主要活性位点(S1-S3)上提供配体与蛋白质结合相互作用的能力,同时定位了一个酰化基团,以便对Ser195羟基进行不可逆的攻击。
