A nucleic acid-drug complex is provided in the present disclosure, which includes a nucleic acid sequence of an anti-PD-L1 aptamer and a CpG oligonucleotide sequence capable of activating TLR9, in which the CpG oligonucleotide sequence consists of a first fragment and a second fragment, and the nucleic acid sequence of the anti-PD-L1 aptamer is inserted between the first fragment and the second fragment.

Nucleic acid-drug complex and use thereof

The present invention provides a nano/micro bubble system for drug delivery comprising a gas core, a plurality of surfactants and an active ingredient. The surfactants surround the gas core and form a double-layer structure having an inner layer and outer layer. The active ingredient is embedded in a gap formed between the inner layer and the outer layer of the double-layer structure and comprises a nucleic acid, a peptide or a protein.

Nano / micro bubbles for drug delivery

The pharmaceutical composition includes a drug layer comprising an active ingredient, a surfactant, an acidic component and an effervescent ingredient. The active ingredient comprises a nucleic acid, a peptide or a protein. The acidic component and effervescent ingredient of the drug layer are dissolved in the water to react for generating carbon dioxide and bubbles thereof. The surfactants surround the carbon dioxide gas core and form a double-layer structure having an inner layer and outer layer. The active ingredient is embedded in a gap formed between the inner layer and the outer layer of the double-layer structure.

Pharmaceutical composition for preparing drug delivery nano/micro bubbles

A method for oral administration of an active ingredient to a subject is provided whereby a plurality of bubbles containing the active ingredient t are formed in a small intestinal of the subject. The method includes administering orally to the subject an effective amount of the above-mentioned pharmaceutical composition. The pharmaceutical composition includes a drug layer and an enteric coating layer. The drug layer comprises an active ingredient, a surfactant, an acidic component and an effervescent ingredient. The active ingredient comprises a nucleic acid, a peptide or a protein. When the acidic component of the drug layer is dissolved in the small intestinal to react with the effervescent ingredient for generating carbon dioxide and the plurality of bubbles containing the active ingredient, and the active ingredient is embedded in a gap formed between an inner layer and an outer layer of an double-layer structure formed by the surfactant.
