Popis: The development of mitochondria-targeting cell permeable vectors represents a promising therapeutic approach for several diseases, such as cancer and oxidative pathologies. Nevertheless, access to mitochondria can be difficult. A new hybrid material composed by poly(lactide-co-glycolide) (PLGA) functionalized with a 6-mer mitochondria penetrating peptide (MPP), consisting in alternating arginine and unnatural cyclohexylalanine, was developed. Circular dichroism, FT-IR and DSC studies indicated that the conjugation of the peptide with the polymer led to the obtainment of a more rigid material with respect to both PLGA and MPP as such. In particular, a conformational rearrangement to a helical structure was observed for MPP. MPP-PLGA conjugates were used for the preparation of nanoparticles that showed no cytotoxicity in MTT assay, suggesting their putative use for future studies on mitochondria targeting.
