Disclosed herein are compositions comprising one or more therapeutic proteins for oral administration. The disclosed proteins, which may be directed to a variety of GI and systemic target antigens, resist denaturation and degradation in the stomach and intestines of a patient. The disclosed proteins may be delivered intact to a target region within the gut, or anywhere in body to target specific molecules, cells, tissues, or organs. In some embodiments, the disclosed proteins may include two or more proteins for targeting two or more target antigens.

Provided herein are methods and compositions for preventing atopic march and treating a skin condition.

In an embodiment of the invention, a composition for treating a cell population comprises an Affinity Medicant Conjugate (AMC). The medicant moiety can be a toxin including an acylfulvene or a drug moiety. The affinity moiety can be an antibody, a binding protein, a steroid, a lipid, a growth factor, a protein, a peptide or non peptidic. The affinity moiety can be covalently bound to the medicant via a linker. Novel linkers that can be directed to cysteine, arginine or lysine residues based on solution pH allow greater flexibility in preserving and/or generating specific epitopes in the AMC.

Disclosed are a type of mitochondria-targeted polypeptides, the preparation method and the uses thereof. The polypeptide is abbreviated as MTP. The synthesis method of the present disclosure is simple, and the mitochondria-targeted polypeptide prepared by the method can specifically target the mitochondria of cells and are basically non-toxic to cells. In addition, these synthesized polypeptides demonstrate good cell-membrane-penetrating properties, and can conveniently undergo further multi-functional derivation and modification, thereby providing a potential delivery tool for the preparation of a mitochondria-targeted medicament.

A conjugate compounds or pharmaceutically acceptable salt thereof, comprises a payload and two or more kinds of cell-interacting molecules. The cell-interacting molecules are ligands capable of specifically binding to a cell surface receptor. A method of treating diseases, comprises delivering a payload to a subject.

A composition for reducing damage associated with oxidative phosphorylation. The composition comprises an upregulating compound mixture configured to upregulate an endogenous antioxidant system, an exogenous antioxidant mixture configured to inhibit oxidation of biomolecules by reactive oxygen species, and a mineral mixture configured to provide one or more cofactors to a endogenous antioxidant enzyme. The endogenous antioxidant system includes a Nrf2 transcription factors that promotes transcription of antioxidant genes.

The present invention relates to a physiologically active substance to which a biotin moiety is bound; and a composition for oral administration comprising same. A physiologically active substance to which a biotin moiety is bound has excellent oral absorption into the body.

Compositions and methods for the prevention and/or treatment of SARS-CoV-2 infection and/or COVID-19 are described.

Disclosed herein are prenatal dosage forms formulated for different stages of the pregnancy cycle. Also disclosed are methods of administering prenatal dosage forms to a prenatal, pregnant or lactating woman. Further disclosed are kits including prenatal dosage forms.

Provided herein are bifunctional compounds with a moiety (e.g., lenalidomide, thalidomide) that is a binder of an E3 ubiquitin ligase (e.g., Cereblon) and another moiety (e.g., RA190) that is a binder of the ubiquitin receptor RPN13 to induce degradation of RPN13 and thereby inhibit proteasome function. Also provided are pharmaceutical compositions comprising the bifunctional compounds, and methods of treating and/or preventing diseases (e.g., proliferative diseases, cancers, benign neoplasms, pathological angiogenesis, inflammatory diseases, and autoimmune diseases). Provided also are methods of inducing the degradation of ubiquitin receptor RPN13 by administering a bifunctional compound or composition described herein, wherein one component of the bifunctional compound is a binder of an E3 ubiquitin ligase (e.g., lenalidomide, thalidomide) and another component of the compound is a binder of ubiquitin receptor RPN13 (e.g., RA190) in a subject.
