Applicazioni

Methyl-β-cyclodextrin (M-β-CD) can be used as a reactant to prepare ternary inclusion complex of diclofenac (DCF) in the presence of monoethanolamine (MEA). This complex improves the percutaneous absorption of DCF in human skin. It can also be used to form an inclusion complex with olanzapine (OLP) to increase its solubility for efficient drug delivery.

Here, we describe the chemical characterization of the inclusion complex between diclofenac (DCF) and methyl-beta-cyclodextrin (M-beta-CD) in the presence or absence of monoethanolamine (MEA). Several techniques were used to analyze the complex both in solution and in the solid state.

Cholesterol homoeostasis is critical for cell viability and proliferation. The SREBP (sterol regulatory element-binding protein) pathway is crucial for the maintenance of cholesterol homoeostasis. This pathway is controlled by cholesterol and cholesterol-derived oxysterols. J774 cells cannot convert desmosterol into cholesterol

Changing the concentration of cholesterol in the plasma membrane of isolated outer hair cells modulates electromotility and prestin-associated charge movement, suggesting that a similar manipulation would alter cochlear mechanics. We examined cochlear function before and after depletion of membrane cholesterol
