RALA peptide

RALA peptide is a cationic amphiphilic delivery agent targeting cell membranes, which forms nanoparticles through electrostatic interactions with anionic drugs. RALA peptide has pH-responsive binding properties, which can enhance the α-helical conformation in an acidic environment and destroy the endosomal membrane, promote the release of drugs into the cytoplasm, and exert efficient intracellular delivery activity. RALA peptide can be used in cancer research (enhancing the activity of bisphosphonates against prostate cancer and breast cancer cells) and bone tissue engineering (promoting osteoblast collagen deposition and extracellular matrix mineralization) [1][2][3].
