PDD1滴丸的藥代動(dòng)力學(xué)研究
[Abstract]:Pseudoginsenoside DD1 (PDD1 for short) is composed of (20Sn24S) -Dama -20C20-epoxy-3- 尾 -oxy-12 尾 -triol. It is a new compound of Oktiron type, which was synthesized by side chain oxidation cyclization with Protopanaxdiol,PPD1 as the raw material of pseudo-ginsenoside saponins. The results showed that the synthetic process of PDD1 was mature and had a good antiarrhythmic effect. The toxicological results showed that its toxicity was relatively low. On the basis of this, our group has developed PDD1 dropping pills with antiarrhythmic effect by using PDD1 as the raw material, and has completed the research on the production process of the raw material and its preparation. The main pharmacodynamic and toxicological studies have been completed. The plasma concentration-time curve (Pharmacokinetics,PK) is applied to the application of kinetic principles and mathematical treatment methods. Quantificationally describing the "volume time" dynamics of (Distribution), metabolism of (Metabolism) and excretion of (Excretion) through various ways, ADME, is of great significance in the research and development of innovative drugs [2]. In this study, a UPLC-MS/MS quantitative analysis method for PDD1 in plasma, tissue and excreta of rats was established for the first time. The content of PDD1 in biological samples of rats was determined by intragastric administration of PDD1 dropping pill and intravenous injection of PDD1. The absorption, tissue distribution, excretion, plasma protein binding rate and absolute bioavailability of PDD1 in rats were elucidated. A PDD1 method for identifying metabolites in rats was established, and the metabolic law of PDD1 in rats was revealed. The purpose of this paper is to study the pharmacokinetics of PDD1 in rats, to further clarify its efficacy and safety, and to provide a scientific basis for the development of novel antiarrhythmic drugs based on PDD1.
