Abstract

This study aimed to investigate changes in the solubility and antimicrobial efficacy of cefuroxime axetil (CA) when incorporated into cyclodextrin (CD). While choosing the CD, the validated in silico model was used. A theoretical model based on docking and molecular mechanics/generalized born surface area was validated using a curated dataset of API (active pharmaceutical ingredient)-CD stability constants. The library of commonly used cyclodextrins was virtually screened, indicating CA -hydroxypropyl-βCD (HPβCD) as the most thermodynamically favored system. Solid-state CA-HPβCD system was prepared and characterized by differential scanning calorimetry (DSC), Fourier-transform infrared (FT-IR), and X-ray diffraction (XRPD) methods. The dissolution profiles of the CA and its cyclodextrin system were evaluated. Microbiological activity of the CA-HPβCD inclusion system was studied based on changes in minimal inhibitory concentration (MIC) values and related to ones of the pure CA. The theoretical model was successfully validated, obtaining an average correlation with experimental data R = 0.7. The dissolution study showed significantly improved dissolution profiles of CA-HPβCD compared to CA. HPβCD increases the antimicrobial efficacy of CA up to 4-fold compared to pure CA.

摘要

本研究旨在探讨头孢呋辛酯(CA)与环糊精(CD)结合时的溶解度和抗菌功效变化。在选择 CD 时,使用了经过验证的计算模型。该模型基于对接和分子力学/广义 Born 表面面积理论,使用经过精心整理的 API(活性药物成分)-CD 稳定性常数数据集进行了验证。对常用的环糊精文库进行了虚拟筛选,表明 CA-羟丙基-βCD(HPβCD)是热力学上最有利的体系。通过差示扫描量热法(DSC)、傅里叶变换红外(FT-IR)和 X 射线衍射(XRPD)方法对 CA-HPβCD 固态体系进行了制备和表征。评估了 CA 及其环糊精体系的溶解曲线。根据最小抑菌浓度(MIC)值的变化,研究了 CA-HPβCD 包合体系的微生物活性,并将其与纯 CA 的 MIC 值进行了相关比较。该理论模型得到了成功验证,实验数据的平均相关系数 R 为 0.7。溶解研究表明,与 CA 相比,CA-HPβCD 的溶解曲线显著改善。与纯 CA 相比,HPβCD 将 CA 的抗菌功效提高了 4 倍。
