Descripción general

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

Aplicación

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

Acciones bioquímicas o fisiológicas

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

Nota de preparación

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

Patients treated with amiodarone accumulate lysobisphosphatidic acid (LBPA), also known as bis(monoacylglycero)phosphate, in airway secretions and develop in different tissues vacuoles and inclusion bodies thought to originate from endosomes. To clarify the origin of these changes, we studied in vitro

The level of cholesterol in host cells has been shown to affect viral infection. However, it is still not understood why this level of regulation is important for successful infection. We have shown in this study that dengue virus infection

The therapeutic applications of lipid nanoparticle (LNP) formulations of small interfering RNA (siRNA), are hampered by inefficient delivery of encapsulated siRNA to the cytoplasm following endocytosis. Recent work has shown that up to 70% of endocytosed LNP-siRNA particles are recycled

Niemann-Pick C1 (NPC1) is a lysosomal membrane protein that exports cholesterol derived from receptor-mediated uptake of LDL, and it also mediates cellular entry of Ebola virus. Cholesterol export is inhibited by nanomolar concentrations of U18666A, a cationic sterol. To identify
