Background: Understanding structural interactions between the active drug and conjugated nanoparticles is critical for optimizing intracellular drug transport and for increasing nano drug efficacy. In this regard, analyzing the conformational deformation of conjugated drugs surrounding nanoparticles is essential to understand the corresponding nanodrug efficacy.

Purpose: The objective of this study is to present an optimal synthesis method for efficient drug delivery through a clear structural analysis of nanodrugs according to the type of conjugation.

Methods And Results: In this study, the structural variation of methotrexate (MTX) surrounding carbon nanotubes, depending on the type of conjugation style, such as covalent and non-covalent (PEGylation) bonds, was investigated. Specifically, covalent bonds of MTX surrounding CNTs induced greater structural deformation compared to non-covalent bonds (ie, PEGylated CNT).

Conclusion: Greater changes in the structural variations of MTX analyzed by nuclear magnetic resonance (NMR) significantly improved the anti-inflammatory drug efficacy of human fibroblast-like synovial cells (FLS) via stable drug release in the extracellular environment and burst drug release under intracellular conditions.

The prevalence of individuals with overweight and obesity has increased by 18% since 1990 and it is projected that by 2030, nearly 50% of US adults will have obesity. Lifestyle modifications, such as diet and exercise, typically lead to approximately 3-5% weight loss, whereas 5-15% weight loss is necessary to significantly impact obesity-associated comorbidities and improve overall health outcomes. In addition to lifestyle modifications, pharmacotherapy has been utilized as an adjunctive treatment to increase weight loss and improve health outcomes.

Pediatric-onset multiple sclerosis (POMS) refers to multiple sclerosis with onset before 18 years of age. It is characterized by a more inflammatory course, more frequent clinical relapses, and a greater number of magnetic resonance imaging (MRI) lesions compared with adult-onset MS (AOMS), leading to significant impacts on both disability progression and cognitive outcomes in affected individuals. Managing POMS presents distinct challenges due to the unique needs of pediatric patients and the limited number of disease-modifying therapies (DMTs) approved for pediatric use.
