Provided herein are methods and compounds for post-translational regulation of cytochrome P450 46A1 (CYP46A1) enzyme activity in the brain and retina. Also, a method for identifying a potential regulator of a CYP46A1 enzyme using crystal structures of the enzyme and a subsequent method for screening for a regulatory activity in the presence of CYP46A1 enzyme are provided. In addition, the regulator compounds that either inhibit or stimulate cholesterol hydroxylation by the CYP46A1 enzyme are provided. Further provided is a method of treating a pathoneurological condition associated with increased cholesterol levels in the brain and retina using the stimulatory compounds.
