LIPID NANO DRUG DELIVERY SYSTEM TARGETING BRAIN LESION AND PREPARATION METHOD AND APPLICATION THEREOF
A lipid nano drug delivery system targeting a brain lesion and a preparation method and application thereof. The drug delivery system comprises a lipid, a delivery drug, and a functional penetrating peptide, and the functional penetrating peptide is formed by covalently connecting a peptide chain linking a nanocarrier end, an arginine-rich penetrating peptide, a matrix metalloproteinase-9 sensitive peptide, and a polyanion inhibitory peptide. The lipid nano drug delivery system can be used for targeting the brain lesion and realizing mitochondrial enrichment by means of modification of the functional penetrating peptide. The repair of mitochondria is realized by encapsulating peptide drug cyclosporin A by means of a lipid nanoparticle core by utilizing a dilution-induced precipitation technique, thereby solving the problems that current cyclosporin A is difficult to effectively reach a brain lesion and the therapeutic window is small, and improving the ability to repair cells around the brain lesion with a small administration dose.
PEG-LIPID
A PEG-lipid is produced by mixing a cation-PEG-lipid comprising at least one amino group with a sulfated glycosaminoglycan comprising at least one carbonyl group to form a Schiff base intermediate. A reducing agent is added to the Schiff base intermediate to form a sulfated glycosaminoglycan-PEG-lipid. The sulfated glycosaminoglycan-PEG-lipid can be used to biological tissue against thromboinflammation. Coating of biological tissue with the sulfated glycosaminoglycan-PEG-lipid can be done in a single step process and does not cause any significant cell aggregation.
Formulated and/or co-formulated compositions containing A2aR antagonist prodrugs useful in the treatment of cancer and methods thereof
Formulated and/or co-formulated nanocarriers (e.g., LNPs and/or SLNPs) comprising AR Prodrugs and methods of making the nanocarriers are disclosed herein. The AR prodrug compositions comprise a drug moiety, a lipid moiety, and linkage unit that inhibit A2aR. The AR Prodrugs can be formulated and/or co-formulated into a nanocarrier to provide a method of treating cancer, immunological disorders, and other disease by utilizing a targeted drug delivery vehicle.
Methods for the preparation of a pharmaceutical-vesicle formulation and associated products and uses
The invention relates to methods for the preparation of a pharmaceutical-vesicle formulation comprising steps of: preparing and processing vesicle components and a pharmaceutical agent to entrap the pharmaceutical agent in the vesicle and form a pharmaceutical-vesicle formulation, wherein the pharmaceutical-vesicle formulation is reconstituted in a known quantity of the pharmaceutical agent dissolved in a pharmaceutically-acceptable carrier to provide a biphasic pharmaceutical-vesicle formulation. The invention also relates to the associated pharmaceutical-vesicle formulations, pharmaceutical kits and uses as a medicament, in particular for the prevention or treatment of infection by bacteria such as Burkholderia pseudomallei and Francisella tularensis, and viruses such as Venezuelan Equine Encephalitis Virus (VEEV).
