Ferulic acid (FA) is a ubiquitous natural plant bioactive with distinctive promise in neurodegenerative disorders.但由于水溶性差、渗透性差跨亲友屏障和广度优先代谢代谢,其治疗效果受到损害The current studies, therefore, were undertaken to systematically develop chitosan-coated solid lipid nanoparticles (SLNs) using QbD paradigms for improved efficacy of FA in the management of Alzheimer's disease (AD).
Highlights
Chitosan-coated SLNs via nose-to-brain with improved anti-Alzheimer's efficacy.
QbD-enabled formulation, yielding holistic product and process comprehension.
Superior nasal bioadhesion and bioavailability of FA for extended duration.
Distinctly reduced oxidative stress following intranasal administration of SLNs.
Significant augmentation in cognitive performance of animals treated with SLNs.
SLNs of FA were formulated employing Compritol as lipid and polysorbate 80 as surfactant and optimised using a 32 Central Composite Design (CCD).优化配方使用离子凝胶与chitosan相加,展示粒度185纳米,绑定效率51.2%和zeta潜能12.4mVFTIR和DSC研究验证FA与配方前接受者相容性,PXRD解释药物晶性重大损失,FESEM描述单球纳米粒子的存在并少聚合sLNs获取了使用山羊鼻膜粘合物和渗透研究的显著改善,并扩展了 'em'in vitro 释放毒品sls认知能力大有提高,通过行为研究期间脱机时间下降,加之各种生化参数和体重增高显著提高,在AD诱导鼠中观测到。

In this work, nanocomposites that combine mucopenetrating and mucoadhesive properties in a single system are proposed as innovative strategy to increase drug residence time in the intestine following oral administration.To this aim, novel mucoadhesive chitosan (CH) sponges loaded with mucopenetrating nanoemulsions (NE) were developed via freeze-casting technique. Highlights • The modulation of the nanocomposite structural features affects the stability of the sponge and the NE release profile in simulated intestinal environment. • PEGylated NE shows effective mucopenetrating properties. • The mucoadhesive ability of CH sponges concentrates NE at the intestinal site and increases the intestinal residence time following oral administration. The NE mucopenetration ability was determined studying the surface affinity and thermodynamic binding of the nanosystem with mucins.纳米粒子穿透预构模层的能力得到了三维时圈Condocal激光扫描显微镜像的验证显微镜观察(扫描电子显微镜和光显微镜)显示NE参与海绵结构,影响海绵稳定性和NE带HCT 116和Caco-2细胞线时,NE证明在广聚度上可兼容性 。 最后,纳米复合点生物分布在健康小鼠口服控制后评价与NE悬浮相比,装入海绵时NE肠保留量高增总体结果显示 开发纳米复合海绵 是一个有希望系统 持续提供药肠a href='https/www.scient.com/science/abs/pi/S01683659210681目标='blank'rels受控发布杂志2021年https://doi.org/10.1016/j.jconrel.2021.04.004.
