Abstract
This research investigates the design and application of phase-separating peptides for direct cytosolic drug delivery. Novel peptides (GHGXY)4, with variable amino acids, were synthesized using microwave-assisted chemistry to enhance phase separation and membrane fusion. In vitro experiments utilizing advanced imaging techniques demonstrated the peptides' capability to form coacervates and facilitate direct cargo, DNA, mRNA, and protein, delivery into the cytosol, bypassing traditional cellular barriers. The study also explores the role of inhibitor Bafilomycin and NH4Cl in phase-separating peptides functionality, offering significant insights into their delivery mechanisms. This research underscores the potential of phase-separating peptides in improving therapeutic delivery strategies.
