20230052618 · 2023-02-16 ·

A nanobowl-supported drug-loaded liposome, a preparation method therefor, and an application thereof. The preparation method for the nanobowl-supported drug-loaded liposome comprises: incubating and ultrasonically treating a nanobowl and a liposome and then successfully encapsulating a drug by utilizing an ammonium sulfate active drug loading method to obtain the nanobowl-supported drug-loaded liposome. The nanobowl-supported drug-loaded liposome can resist the influence of plasma proteins and blood flow shearing forces on drug leakage, enhance the delivery of the drug at a tumor site, improve carrier stability, and improve an anti-tumor curative effect.

OXAZOLIDINONE COMPOUNDS, LIPOSOME COMPOSITIONS COMPRISING OXAZOLIDINONE COMPOUNDS AND METHODS OF USE THEREOF

Compositions and methods for the treatment of tuberculosis, as well as other mycobacterial and gram positive bacterial infections are disclosed. These compositions contain a highly potent and selective oxazolidinone encapsulated with high efficiency to maximize dosing potential of low toxicity drugs, and are stable in the presence of plasma. The compositions are long circulating and retain their encapsulated drug while in the circulation following intravenous dosing to allow for efficient accumulation at the site of the bacterial or mycobacterial infection. The high doses that can be achieved when combined with the long circulating properties and highly stable retention of the drug allow for a reduced frequency of administration when compared to daily or twice daily administrations of other drugs typically utilized to treat these infections.

CAROTENOID COMPOSITIONS AND USES THEREOF

Provided herein are pharmaceutical compositions comprising carotenoids, including liposomes that encapsulate carotenoids including ionizable carotenoids such as trans-crocetin. The provided compositions have uses in treating diseases, disorders and conditions associated with, but not limited to, infection, endotoxemia, inflammation, sepsis, ischemia, hypoxia, shock, stroke, lung injury, wound healing, traumatic injury, reperfusion injury, cardiovascular disease, kidney disease, liver disease, inflammatory disease, metabolic disease, pulmonary disorders, blood related disorders and hyperproliferative diseases such as cancer. Methods of making, delivering, and using the pharmaceutical compositions are also provided.

CABAZITAXEL WEAKLY- ALKALINE DERIVATIVE AND FORMULATION THEREOF

A cabazitaxel weakly-alkaline derivative, preparation, and synthesis thereof, a liposome preparation containing the cabazitaxel weakly-alkaline derivative and application of the cabazitaxel weakly-alkaline derivative in a drug delivery system are provided. Cabazitaxel is connected with a weakly-alkaline intermediate through an ester bond, the ester bond can be broken under the action of esterase in vivo, and an active drug is released. A connecting group is C.sub.1-C.sub.4 alkyl, C.sub.3-C.sub.6 naphthenic base or phenyl; [N] is an N-methyl piperazinyl group, a piperidinyl group, a 4-(1-piperidinyl) piperidinyl group, a morpholinyl group, a pyrrolidine group or other tertiary amine structures. The cabazitaxel weakly-alkaline derivative can be prepared into the liposome preparation having high drug loading capacity, high encapsulation efficiency, and good stability. The in-vivo circulation time of the drug can be greatly prolonged, the accumulation amount of the drug at a tumor part is increased, and the anti-tumor effect and the tolerance dose are improved.

RNA-LOADED NANOPARTICLES AND USE THEREOF FOR THE TREATMENT OF CANCER

Provided herein are compositions comprising a liposome comprising ribonucleic acid (RNA) molecules and a cationic lipid, wherein the RNA molecules bind to or encode an epitope of a nucleic acid encoding a fusion protein expressed by a tumor. The disclosure also provides a nanoparticle comprising a positively-charged surface and an interior comprising (i) a core and (ii) at least two nucleic acid layers, wherein each nucleic acid layer is positioned between a cationic lipid bilayer, and nucleic acid molecules in the nucleic acid layers comprise a sequence of a nucleic acid molecule expressed by slow-cycling cells (SCCs). Also provided herein re methods of making a nanoparticle and methods of increasing an immune response against a tumor in a subject. Methods of treating a subject with a disease are provided herein.

Pharmaceutical formulations of PEGylated liposomes and blood coagulation factors

The present invention provides a pharmaceutical composition for subcutaneous administration comprising a blood factor and a colloidal particle comprising about 0.5 to 20 mole percent of an amphipathic lipid derivatized with a biocompatible hydrophilic polymer, wherein the blood factor is not encapsulated in said colloidal particle.
