New Liquid Biomaterials for Nanoemulsion-mediated Drug Delivery
Padilla, Marshall Scott ; UNIVERSITY OF WISCONSIN-MADISON,2021.
More
Abstract: Most potent therapeutics fail to reach clinical trials and FDA-approval due to their inability to reach their target in a safe and controlled manner. To overcome these barriers, nanotechnology can be employed to create vehicles that aid in the delivery of drugs. One promising class of drug delivery vehicles are nanoemulsions, which are nanometer-sized particles that contain a hydrophobic droplet that houses and protects the therapeutics. Nanoemulsions have seen success in the delivery of drugs as several nanoemulsion formulations have received FDA-approved. However, despite their success, one of their limiting factors is their lack of diverse hydrophobic components. Typically, the hydrophobic droplet is a lipid, and as a result, only drugs that are lipophilic can be dissolved. This means that hydrophilic small molecule and biological therapeutics cannot be formulated, significantly reducing the potential of this drug delivery vehicle.

---|---|---|
69% | Dissolve 1 g of p-nitrobenzenesulfonamide in DMF and add 1.0 g of sodium hydride under an ice bath. Stir for 30 minutes and add dropwise.2.1 g of iodomethane was stirred at room temperature for 2 hours and the reaction was complete. Insoluble material was filtered off, water was added, solids were stirred, precipitated, filtered, and dried to give a pale yellow solid which was directly put into the next reaction.2.3g of the above product was added to methanol and 1g of 10% palladium on carbon was added. A few drops of acetic acid were added dropwise at 50C.After 6 hours, at the end of the reaction, the catalyst was removed by filtration, washed twice with dichloromethane, and the combined filtrates were evaporated to remove the solvent and purified by column chromatography.(Yellowish solid, 1.38g, yield 69%. |
