General description

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

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.
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
  • in treating seminiferous tubules to study its effects on the localization pattern of VPS35-positive vesicles
  • to study the U18666A treatment effects on early endosomes and late endosomes/multivesicular bodies (MVBs)
  • as an NPC1 inhibitor to test its in vivo efficacy and study its effects on filovirus entry and infection

Biochem/physiol Actions

U18666A, a Niemann-Pick phenotype inducer, can inhibit the lysosomal cholesterol export and Ebola infection.
Inhibitor of cholesterol synthesis (inhibits desmosterol Δ24-reductase). Weak inhibitor of hedgehog (hh) signaling.

Preparation Note

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

Niemann-Pick type C disease (NPC) is a lysosomal storage disorder causing accumulation of unesterified cholesterol in lysosomal storage organelles. Recent studies have shown that hydroxypropyl-beta-cyclodextrin injections in npc1(-/-) mice are partially effective in treating this disease. Using cultured fibroblasts, we
