Methods for rapid, efficient, and safe fluoridation and radiolabeling of established and new biomarkers are described. More specifically, the described herein methods may be used for fluoridation of biomarkers or to facilitate isotopic exchanges, especially .sup.19F/.sup.18F IEX, for rapid and efficient manufacturing of radiotracers, including radiotracers for positron emission tomography (PET), under clinically relevant conditions.

The present invention is directed to compounds having the Formula (I), (II), (III), (IV), and (V), compositions thereof, and methods for the treatment of a condition associated with a dysfunction in proteostasis.

A chelating compound of formula (I) or a pharmaceutically acceptable salt thereof and its complexes with metals or radioisotopes thereof. The invention further relates to the preparation of such ligand and complexes as well as to their use as diagnostic or therapeutic agents. ##STR00001##

The present invention relates to a radioactive halogen-labeled pyrido[1,2-a]benzimidazole derivative compound represented by a specific general formula or a salt thereof, or a radiopharmaceutical comprising the same.

The present disclosure relates generally to LRRK2 inhibitors, or a pharmaceutically acceptable salt, deuterated analog, prodrug, tautomer, stereoisomer, or mixture of stereoisomers thereof, and methods of making and using thereof.

Provided are a substituted benzimidazole compound, and a composition comprising same and use thereof. The substituted benzimidazole compound is a compound represented by formula (I), or a pharmaceutically acceptable salt, prodrug, hydrate or solvate compound, polymorph, stereoisomer, or isotopic variation thereof. The compound can be used for treating and/or preventing related diseases caused by MEK, such as hyperproliferative diseases, pancreatitis, kidney diseases, blastocyte implantation, and diseases related to vasculogenesis or angiogenesis.

##STR00001##

Provided herein are compounds, pharmaceutical compositions, and methods for treating a SARS-CoV-2 infection.

Disclosed herein are methods for the fluorination aromatic N-heterocyclic N-oxides that comprise at least one leaving group. The N-oxides may be reduced to the fluorinated aromatic N-heterocyclic amine analogs. This novel fluorination approach may be successfully applied for synthesizing aromatic N-heterocyclic compounds labeled with .sup.18F.

Prosthetic compounds are disclosed that are effective for radiolabeling biomolecules with 18F. Representative biomolecules include antibodies (e.g., monoclonal antibodies (mAbs) and nanobodies (sdAbs)), antibody fragments, and peptides that may have an affinity for particular types of cells, such as cancer cells. The prosthetic compounds effectively address the art-recognized difficulties associated with the retention of radioactivity within the targeted cells, due to internalization of the biomolecule, followed by proteolytic degradation. Representative prosthetic compounds include (i) a succinimidyloxycarbonyl moiety, (ii) a radioactive moiety bearing 18F, and (iii) a charged moiety, i.e., a moiety that is charged under the physiological conditions of the internal cell environment.

A compound represented by Chemical Formula 1, and a photoelectric device, an image sensor, and an electronic device including the same are disclosed.
