Carriers may manifest progressive muscle weakness, resulting from the progressive degeneration of skeletal muscles, generating cardiac and respiratory disorders. Considering the lack of effective treatments, different therapeutic approaches have been developed, such as protein synthesis and extracellular matrix derivatives that can be used to improve muscle regeneration, maintenance, or repair. At the same time, the use of other anti-inflammatory drugs or biological agents to replace corticosteroids conjugated to these extracellular matrix derivatives may act more effectively in controlling the progression of Duchenne muscular dystrophy. Extracellular matrix-derived peptides (eg laminin-111 derivatives) and the use of essential oils with antiinflammatory activity in polymeric particles for application in the treatment of Duchenne muscular dystrophy are discussed. For this purpose, the literature of patents and scientific articles from 2012- 2024 on LM-111 peptides and Duchenne muscular dystrophy was reviewed. Many patents focus on palliative technologies that seek to prolong the progressive effects of the disease, considering the control of the inflammatory process.

We examine the molecular pathways through which polyphenols exert their effects, including their influence on oxidative stress modulation, inflammatory responses, cellular proliferation, apoptosis, and estrogen receptor signalling. Additionally, this review addresses innovative nano-based drug delivery systems such as nanoparticles, liposomes, niosomes, and phytosomes that enhance the stability, bioavailability, and targeted delivery of polyphenols. These advanced formulations aim to overcome challenges related to polyphenol degradation, low solubility, and rapid systemic clearance, thereby enhancing their therapeutic efficacy.

This study aims to investigate a novel approach that integrates smart drug delivery systems with real-time imaging modalities. The goal is to enhance the targeted delivery of therapeutic agents to cancer cells, minimizing damage to healthy tissues while improving the overall efficacy of cancer treatments. Smart drug delivery systems are designed to transport medications directly to tumor sites, enhancing treatment precision. When combined with real-time imaging tools such as MRI, CT, PET, and molecular imaging, these systems offer real-time data on the tumor's location, size, and response to treatment. This allows for immediate adjustments in therapy, ensuring optimal drug delivery and reducing side effects. However, the implementation of this approach also faces challenges, including the need for stringent safety protocols and adherence to regulatory standards.
