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.

Cholesterol sulfate is a sulfated cholesterol. At concentrations of 5-100 μM for 24 h, it activates the SREBP2 signaling pathway in a dose-dependent manner in SULT2B1-knockout human colon cancer cell line HT-29, and this activating effect is enhanced upon SLC10A6 overexpression[3].
Cholesterol sulfate (25-50 μM; 6-18 h) promotes the proteolytic activation of SREBP2 in HEK293T cells[3].

Cholesterol sulfate (25-50 μM) increases the cell viability of HT-29 human colon cancer cells treated with 25 or 50 μM cholesterol sulfate, as well as SULT2B1-knockout HT-29 human colon cancer cells, and this effect depends on the activation of SREBP2[3].

Cholesterol sulfate (12.5-25 μM; 5 h) promotes ubiquitination and proteasomal degradation of wild-type HMGCR in Huh-7 cells, and this process depends on Lys89 and Lys248 of HMGCR[4].
Cholesterol sulfate (25 μM; 8 h) promotes the interaction between INSIG1 and HMGCR in HEK 293T cells, a process that mediates the ubiquitination and degradation of HMGCR[4].
Cholesterol sulfate (25 μM; 8 h) promotes the interaction between INSIG1 and SCAP in HEK 293T cells, thereby inhibiting the translocation of SREBP2 to the Golgi apparatus; this interaction depends on the L343 and V355 residues of SCAP, but not on I348[4].
Cholesterol sulfate (25 μM; 4-24 h) reduces LDL-cholesterol uptake in Huh-7 cells through two mechanisms: a secondary effect of cholesterol depletion, and direct inhibition of clathrin-mediated endocytosis[4].

Cholesterol sulfate (30 μM; 2-4 days) inhibits RANKL-induced osteoclast differentiation in a RORα-independent manner, as it exerts comparable inhibitory effects on osteoclast formation and NFATc1 expression in bone marrow macrophages (BMMs) from wild-type (WT) and RORα-deficient mice[5].
Cholesterol sulfate (30 μM; 0.5-24 h) activates the AMPK-Sirt1 axis in a RORα-independent manner, thereby inhibiting NF-κB activity in mouse bone marrow-derived macrophages (BMMs) and RAW264.7 cells[5].
Cholesterol sulfate (30 μM; 10 h-8 days) induces caspase-dependent apoptosis in differentiated murine osteoclasts, disrupts their actin ring structure, and inhibits bone resorptive activity[5].
Cholesterol sulfate (30 μM; 12 h-4 days) induces apoptosis of mouse osteoclasts via AMPK-dependent NF-κB inhibition, thereby reducing the production of IL-1β; treatment with IL-1β reverses the aforementioned pro-apoptotic and inhibitory effects without altering the activation level of AMPK[5].
Cholesterol sulfate induces squamous differentiation of normal human keratinocytes by inhibiting cell growth and upregulating the expression and activity of TGase 1[6].
