Cholesterol sulfate
Cholesterol sulfate is a naturally occurring, orally active cholesterol derivative that is widely distributed in various tissues and body fluids. Cholesterol sulfate acts as a DOCK2 inhibitor, with IC50 values of 2 μM and 2.9 μM against mouse and human targets, respectively. Cholesterol sulfate restricts excessive neutrophil infiltration and alleviates intestinal inflammation and damage. Cholesterol sulfate serves as an activator of protein kinase C (PKC), which promotes squamous cell differentiation and inhibits skin carcinogenesis. Cholesterol sulfate regulates cholesterol homeostasis and cellular metabolism by activating the AMPK-Sirt1 pathway. Cholesterol sulfate can be used in research related to actinic keratitis, ulcerative colitis, skin cancer, and other conditions.
