Cellular senescence has recently been recognized as one of the hallmarks of cancer, aging, as well as many age-related disorders, sparking significant interest in the development of senolytics, compounds that can remove senescent cells. However, most current pharmacological strategies face challenges related to non-specific delivery, leading to significant side effects that hinder safe and effective treatments. To address these issues, galactose-functionalized amphiphiles are synthesized that can self-assemble into micelles and be loaded with a senolytic cargo. These galactose-micelles are responsive to the lysosomal β-galactosidase enzyme, present in elevated amounts in senescent cells, and are employed for specific delivery of the senolytic Bcl2-inhibitor Navitoclax. This novel formulation showed reduced delivery and toxicity to non-senescent cells, thereby increasing the senolytic index of Navitoclax and making it suitable for future in vivo experimental designs to improve selectivity and safety profiles.
