Nanotechnology-Based Delivery Systems for Enhanced Targeting of Tyrosine Kinase Inhibitors: Exploring Inorganic and Organic Nanoparticles as Targeted Carriers

Kinase inhibitors are small molecules that block kinase activity and have significant applications in both therapy and diagnostics. Recent studies suggest that these inhibitors hold great potential as targets for treating a range of diseases, including autoimmune disorders, cardiovascular conditions, cancer, and inflammatory diseases like ulcerative colitis. Ongoing research focuses on developing effective carriers for tyrosine kinase inhibitors (TKIs) to enhance treatment outcomes while reducing side effects. The nano-scale drug carriers have demonstrated the ability to encapsulate a wide range of imaging and therapeutic agents, enhancing tumor diagnosis and treatment. Notably, the incorporation of drugs with poor pharmacokinetics into nanocarriers enhances their solubility and stability, offering a renewed opportunity to assess their full therapeutic potential. The entrapped agents can be released in a controlled manner to maintain a specific drug concentration within a treatment framework or triggered by specific stimuli such as time or pH to target particular tissues or cells. The multifunctionality of nanosystems offers a promising avenue for developing innovative tyrosine kinase inhibitor (TKI) delivery strategies that serve as alternative treatment options for cancer and other inflammatory diseases. This review aims to provide a comprehensive overview of innovative nano-scale delivery systems for TKIs, both as standalone treatments and in combination with other therapeutic agents or drug delivery approaches. We discuss their comparative advantages and limitations for future small-molecule TKIs research.
