Development of solid lipid nanoparticles is one of the emerging fields of lipid nanotechnology (for a review on lipid nanotechnology, see [17]) with several potential applications in drug delivery, clinical medicine and research, as well as in other disciplines. Due to their unique size-dependent properties, lipid nanoparticles can possibly ...
The critical factor that governs tissue tropism is the modulation of the surface's acid dissociation constant (pKa), which corresponds to the pH at which the proportion of charged and uncharged ionizable lipids at the particle's surface is equal and depends on the type of ionizable lipids and charged helper lipids used in the nanoparticle ...
In solid lipid nanoparticles, the drug molecules are dissolved in the particle's solid hydrophobic lipid core, this is called the drug payload, and it is surrounded by an aqueous solution. [6] Many SLNs are developed from triglycerides , fatty acids , and waxes .
Lipid-based carriers include both liposomes and micelles. Examples of gold nanoparticles are gold nanoshells and nanocages . [ 3 ] Different types of nanomaterial being used in nanocarriers allows for hydrophobic and hydrophilic drugs to be delivered throughout the body. [ 5 ]
When the blood vessels form so rapidly, large fenestrae result that are 100 to 600 nanometers in size, which allows enhanced nanoparticle entry. Further, the poor lymphatic drainage means that the large influx of nanoparticles are rarely leaving, thus, the tumor retains more nanoparticles for successful treatment to take place. [8]
Delray Beach, FL, Oct. 01, 2024 (GLOBE NEWSWIRE) -- The global lipid nanoparticles market is on track to grow from USD 271.8 million in 2024 to USD 350.5 million by 2029, driven by advancements in lipid nanoparticle-based pharmaceuticals and their increasing role in anti-cancer and mRNA therapies, especially highlighted by their success in COVID-19 vaccines.
The preparation of ALC-0315 was first described in a patent application to lipid nanoparticles by Acuitas Therapeutics in 2017. [6]: 137 The final step is a reductive amination reaction in which 4-aminobutanol is condensed with a lipid aldehyde, using sodium triacetoxyborohydride as the reducing agent to convert the intermediate imines to the amine of the product.
Lipid nanoparticles (LNPs) are being considered for delivering siRNA to silence AR. The most effective LNP to be found in vivo contains an ionizable cationic lipid 2,2-dilinoleyl-4-(2-dimethylaminoethyl)-[1,3]-dioxolane (DLin-KC2-DMA). [4] Serum prostate specific antigen (PSA) is an antigen that is present in high levels in prostate cancer.
