终末期肾病与进行性心血管钙化 (CVC) 密切相关,目前尚无针对 CVC 的治疗方法。 SNF472 是一种正在开发的用于治疗软组织钙化的实验制剂。我们研究了 SNF472 在大鼠体内的药代动力学及其对 CVC 的抑制作用。在三种大鼠模型中研究了 SNF472:(1)用 1 mg/kg SNF472 静脉推注 SNF472 预防维生素 D3 诱导的 CVC,(2)在钙化诱导后开始,用 10 或 60 mg/kg SNF472 皮下 SNF472 推注抑制维生素 D3 诱导的 CVC 进展,(3)用 50 毫克 SNF472 治疗的腺嘌呤诱导的尿毒症大鼠中的 CVC mg/kg SNF472 通过静脉注射4小时-输注。尿毒症大鼠在静脉注射后表现出比对照动物更低的血浆 SNF472 水平。输液。使用 SNF472 治疗后,非尿毒症大鼠的 CVC 被抑制 60-70%,并且心脏钙化的进展完全被阻断。尿毒症大鼠的 CVC 发育在静脉注射后被抑制高达 80%。输注SNF472。 SNF472 在相同范围的 SNF472 血浆水平下抑制尿毒症和非尿毒症大鼠 CVC 的发生和进展,但在每种情况下使用达到这些水平所需的剂量。这些结果共同支持 SNF472 作为治疗人类 CVC 的新型治疗选择的发展。
End-stage renal disease is strongly associated with progressive cardiovascular calcification (CVC) and there is currently no therapy targeted to treat CVC. SNF472 is an experimental formulation under development for treatment of soft tissue calcification. We have investigated the pharmacokinetics of SNF472 administration in rats and its inhibitory effects on CVC. SNF472 was studied in three rat models: (1) prevention of vitamin D3-induced CVC with an intravenous SNF472 bolus of 1 mg/kg SNF472, (2) inhibition of progression of vitamin D3-induced CVC with a subcutaneous SNF472 bolus of 10 or 60 mg/kg SNF472, starting after calcification induction, (3) CVC in adenine-induced uremic rats treated with 50 mg/kg SNF472 via i.v. 4h -infusion. Uremic rats presented lower plasma levels of SNF472 than control animals after i.v. infusion. CVC in non-uremic rats was inhibited by 60–70% after treatment with SNF472 and progression of cardiac calcification completely blocked. Development of CVC in uremic rats was inhibited by up to 80% following i.v. infusion of SNF472. SNF472 inhibits the development and progression of CVC in uremic and non-uremic rats in the same range of SNF472 plasma levels but using in each case the required dose to obtain those levels. These results collectively support the development of SNF472 as a novel therapeutic option for treatment of CVC in humans.
