一般說明

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

應用

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

生化／生理作用

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.

準備報告

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

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

We characterized the role of 24-dehydrocholesterol reductase (DHCR24) in hepatitis C virus infection (HCV). DHCR24 is a cholesterol biosynthetic enzyme and cholesterol is a major component of lipid rafts, which is reported to play an important role in HCV replication.
