24(S)-hydroxy Cholesterol (24S-OHC) is the terminal product of the cholesterol elimination pathway in neural tissues. It is an LXR agonist and a selective positive allosteric modulator of NMDARs. It can serve as a biomarker for NPD, induce cognitive decline in mice, and is useful for studying neurological diseases.
