Compounds comprising a cross-linking moiety and a protecting group are described herein along with their methods of use. The cross-linking moiety may comprise an indoxyl and the protecting group may comprise a sugar (e.g., a glucuronide or glucoside), phosphoester, or sulfoester group. The cross-linking moiety and protecting group may be attached to each other via an oxygen atom, sulfur atom, or linker. In some embodiments, the linker attaching the cross-linking moiety and protecting group is a self-immolative linker. A compound of the present invention may cross-link under physiological conditions and/or in vivo.

The present disclosure relates to bifunctional compounds, which find utility as modulators of alpha-synuclein (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hippel-Lindau, cereblon, Inhibitors of Apotosis Proteins or mouse double-minute homolog 2 ligand which binds to the respective E3 ubiquitin ligase and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/ inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure. Such diseases or disorders are alpha-synucleinopathies or neurodegenerative diseases associated with alpha-synuclein accumulation and aggregation, such as e.g. Parkinson Disease, Alzheimer's Disease, dementia, dementia with Lewy bodies or multiple system atrophy, in particular Parkinson's Disease.

Efficient radiolabeling reactions are important chemical tools in biomedical research especially in probe construction. Herein, three 18F-labeled vinyl sulfones were prepared. In particular, 18F-PEG1-VS (((2-(2-(fluoro-18F)ethoxy)ethyl)sulfonyl)ethane) could not only allow chemoselective labeling of bioactive molecules containing −XH (X = S, NH) groups, but also react with red blood cells both in vitro and in living mice for potential cell tracking applications. In addition, these hydrophilic agents were found to cross the blood brain barrier (BBB) efficiently and localize at the cerebellum region. In summary, 18F-labeled vinyl sulfones provide a versatile platform for PET probe construction.
Radiolabeled prostate-specific membraneantigen (PSMA) ligands have been rapidly adopted as part of patient care for prostate cancer. In this study, a new series of 18F-labeled PSMA-targeting agents was developed based on the high-affinity Glu-ureido-Lys scaffold and 18F-vinyl sulfones (VSs), the tumoruptake and tumor/major organ contrast of which could be tuned by pharmacokinetic linkers within the

include azido, hydroxy, or biotin positioned at the terminus of a short oligoethyleneglycol (PEG) chain. Three of the indoxyl-glucoside target compounds are N-alkylated with a carboxymethyl unit. The yields of indigoid upon glucosidase treatment were approximately quantitative for the unalkylated compounds versus 1/4–1/3 of that for the N-carboxymethyl analogues. Hybrid joining reactions from two indoxyl-glucosides
