Cholesteryl chloride

Cholesteryl chloride is a derivative of cholesterol that has been investigated for its biological activities and its applications in material science. While studied for potential inhibitory effects on DNA polymerase and topoisomerase activities and human cancer cell growth, these effects were not observed for cholesteryl chloride in the provided contexts. It has been shown to impair the physiological clearance of chylomicron-like lipid emulsions and does not support the growth of human macrophage-like cell lines, indicating specific structural requirements for these biological processes. In material science, cholesteryl chloride is a component of cholesteric liquid crystal mixtures, often combined with cholesteryl nonanoate, to tailor optical properties such as reflectivity, transmission, and optical activity. It has also been identified as an artifact formed during certain analytical procedures involving cholesterol.
