co-crystallization using the multicomponent crystal strategy, not only to optimize the physicochemical properties of single drugs, but also to play a role in the cooperative effect of DBS with the potential vascular protective effects of MET against diabetic retinopathy (DR). The crystal structure analysis demonstrated that MET and DBS were coupled in a 3D supramolecular structure connected by hydrogen-bonding interactions
二甲双胍(MET)和多苯磺酸(DBS)组成的药物-药物多组分晶体采用多组分晶体策略,通过溶剂冷却和蒸发共结晶前瞻性连接,不仅可以优化单药的理化性质,而且可以发挥在 DBS 的协同作用与 MET 对糖尿病视网膜病变 (DR) 的潜在血管保护作用中的作用。晶体结构分析表明,MET 和 DBS 以 1:1 的摩尔比通过氢键相互作用连接成 3D 超分子结构。MET和DBS几乎所有的氢键供体和受体都参与了键合,这阻碍了剩余的潜在氢键位点与水分子的结合,导致吸湿性低于单独的MET。
