Nat Commun:乙二醇低聚物衍生的肌醇磷酸酯对血管钙化的抑制作用

2020-02-27 不详 网络

肌醇六磷酸酯(IP6)是一种天然产物,已知可抑制血管钙化(VC),但给药后效价有限且血浆暴露量低。本研究中,我们报告了一系列肌醇磷酸酯类似物作为结晶抑制剂的设计,其中4,6-二-O-(甲氧基-二甘醇)-肌醇-1,2,3,5-四(磷酸)(皮下注射后,OEG2)2-IP4与IP6相比,显示出更高的体外活性以及更有利的药代动力学和安全性。 (OEG2)2-IP4可有效稳定钙蛋白颗粒(CPP)的生长,在不

肌醇六磷酸酯(IP6)是一种天然产物,已知可抑制血管钙化(VC),但给药后效价有限且血浆暴露量低。

本研究中,我们报告了一系列肌醇磷酸酯类似物作为结晶抑制剂的设计,其中4,6-二-O-(甲氧基-二甘醇)-肌醇-1,2,3,5-四(磷酸)(皮下注射后,OEG2)2-IP4与IP6相比,显示出更高的体外活性以及更有利的药代动力学和安全性。 (OEG2)2-IP4可有效稳定钙蛋白颗粒(CPP)的生长,在不同的VC体外模型(即人血清,原代细胞培养物和组织外植体)中始终显示出低微摩尔活性,并在很大程度上消除了VC在啮齿动物模型中的发育,同时不会引起与血清钙螯合有关的毒性。

总之,该研究结果提示了一种独立于VC病因的作用机制,(OEG2)2-IP4破坏了病理性钙化的成核和生长。
