Opis

General description

U18666A, a cationic amphiphile/sterol, has a diethylaminoethyl chain linked to the 3-hydroxyl. It is an androstenolone derivative.[1]

Application

U 18666A has been used in fibroblast controls to study the mechanism of increase in autophagy in Niemann-Pick Disease Type C (NPC) cells[2].

U 18666A has been used:

• as a competitive inhibitor of the Niemann-Pick disease, type C (NPC2) binding partner Niemann-Pick C1 (NPC1) to treat symbiotic and aposymbiotic adult Aiptasia to study the effect of global sterol transport inhibition[3]
• in treating seminiferous tubules to study its effects on the localization pattern of VPS35-positive vesicles[4]
• to study the U18666A treatment effects on early endosomes and late endosomes/multivesicular bodies (MVBs)[4]
• as an NPC1 inhibitor to test its in vivo efficacy and study its effects on filovirus entry and infection[5]

Biochem/physiol Actions

Inhibitor of cholesterol synthesis (inhibits desmosterol Δ24-reductase). Weak inhibitor of hedgehog (hh) signaling.

U18666A, a Niemann-Pick phenotype inducer[5], can inhibit the lysosomal cholesterol export and Ebola infection.[1]

Preparation Note

U 18666A is soluble in water at 10 mg/ml.
