description
Latest since the approval of the mRNA-based COVID-19 vaccines, the important role of lipid nanoparticles (LNPs) in drug delivery has been generally recognized. All LNPs approved so far consist to a significant extent (30-50%) of the natural lipid Cholesterol or its derivatives. The molar content of Cholesterol has tremendous influence on LNP size and shape, transfection efficiency, and expression levels of the protein(s) encoded by the transported mRNA.
The invention of synthetic strategies to derive Cholesterol from plant-extracted Phytosterols gave way to the bulk scale production of entirely animal-free excipient grade Cholesterol of high and consistent product quality in accordance with Pharmacopoeia requirements.
