NANOPARTICLE PHARMACEUTICAL COMPOSITIONS WITH REDUCED NANOPARTICLE SIZE AND IMPROVED POLYDISPERSITY INDEX
20230233476 · 2023-07-27 ·

Methods of making and using nanoparticle pharmaceutical compositions comprising histidine-lysine copolymers are provided. The solutions spontaneously form nanoparticles when mixed with nucleic acids such as siRNA. Methods are provided where the pH of the nucleic acid solution is controlled prior to mixing leading to a reduction in nanoparticle diameter to a desirable range, typically 100-150 nm, and Polydispersity Index (PDI), both of which improve transport into target cells to improve the efficacy of gene silencing.

Pharmaceutical compositions

The present invention relates to the field of methods for providing pharmaceutical compositions comprising poorly water-soluble drugs. In particular the present invention relates to compositions comprising stable, amorphous hybrid nanoparticles, comprising at least one protein kinase inhibitor and at least one polymeric stabilizing and matrix-forming component, useful in pharmaceutical compositions and in therapy.

Methods for preparing particles and related compositions
11564893 · 2023-01-31 · ·

Methods for preparing particles and related compositions are provided. In some embodiments, the particles include at least one polynucleotide (e.g., mRNA), and in certain embodiments, the particles may include at least one ionizable molecule (e.g., a lipid). A method for preparing a suspension including the particles may comprise one or more filtration steps. In some such embodiments, prior to or during filtration, one or more properties of the particles (e.g., surface charge) and/or one or more properties of the suspension (e.g., pH) may be altered. In some embodiments, altering one or more properties of the particles and/or suspension may improve yield, improve a characteristic of the resulting composition, and/or prevent or reduce certain problems, such as fouling during the filtration process.

Bi2O3 NANOPARTICLES PREPARED BY THE TOP-DOWN ULTRASONICATION ROUTE AS A BROAD-SPECTRUM ANTIMICROBIAL TO OVERCOME DRUG RESISTANCE IN ANTIBIOTICS

α-Bi.sub.2O.sub.3 NPs exhibit not only potent broad-spectrum antibacterial activity of killing both Gram-negative (MIC=0.75 μg/mL vs. P. aeruginosa) and Gram-positive (MIC=2.5 μg/mL vs. S. aureus) bacteria, but they are also effective against Ag-resistant and carbapenem-resistant bacteria (MICs=1.0 μg/mL and 1.25 μg/mL, respectively), and they are able to sensitize bacteria towards meropenem (mero), acting synergistically and thus allowing for its continued use with smaller therapeutic doses (fractional inhibitory concentration=0.45). Importantly, unlike other technologies that have been considered as effective metal antimicrobials, α-Bi.sub.2O.sub.3 NPs do not contribute to the generation of antimicrobial resistant phenotypes with no resistance observed after 30 passages. The Bi-based materials represent a critical tool against multidrug resistant bacteria.
