Sitosterol (synthetic from plant sterol)

β-sitosterol is a phytosterol (plant sterol) found in a wide variety of plants such as pecans, saw palmetto, avocados, pumpkin seed, rice bran, wheat germ, and soybeans. Recently, sitosterol has been investigated as a substitute for cholesterol in lipid-based mRNA delivery systems. In 2020, it was reported that β-sitosterol-substituted lipid nanoparticle (LNPs) maintained comparable size and encapsulation but were considerably more effective at mRNA transfection than LNPs containing cholesterol (Patel, 2020).
