A MedChem toolbox for cereblon-directed PROTACs

A modular chemistry toolbox was developed for cereblon-directed PROTACs. A variety of linkers was attached to a CRBN ligand via the 4-amino position of pomalidomide. We used linkers of different constitution to modulate physicochemical properties. We equipped one terminus of the linker with a set of functional groups, e.g. protected amines, protected carboxylic acids, alkynes, chloroalkanes, and protected alcohols, all of which are considered to be attractive for PROTAC design. We also highlight different opportunities for the expansion of the medicinal chemists' PROTAC toolbox towards heterobifunctional molecules, e.g. with biotin, fluorescent, hydrophobic and peptide tags.

COMPOUNDS USEFUL FOR TREATING GASTROINTESTINAL TRACT DISORDERS

The present disclosure is directed to compounds and methods for the treatment of disorders associated with fluid retention or salt overload, such as heart failure (in particular, congestive heart failure), chronic kidney disease, end-stage renal disease, liver disease, and peroxisome proliferator-activated receptor (PPAR) gamma agonist- induced fluid retention. The present disclosure is also directed to compounds and methods for the treatment of hypertension. The present disclosure is also directed to compounds and methods for the treatment of gastrointestinal tract disorders, including the treatment or reduction of pain associated with gastrointestinal tract disorders.

Disassembly-driven turn-on fluorescent nanoprobes for selective protein detection

"Switchable" fluorescent probes, which induce changes in the fluorescence properties (e.g., intensity and/or wavelength) only at the intended target protein, are particularly useful for selective protein detection or imaging. However, the strategy for designing such smart probes remains very limited. We report herein a novel mechanism for generating protein-specific "turn-on" fluorescent probes. Our approach uses an amphiphilic, self-assembling compound consisting of a fluorophore and a protein ligand. In the absence of target protein, the probe forms self-assembled aggregates in aqueous solution and displays almost no fluorescence because of efficient quenching. On the other hand, it emits bright fluorescence in response to the target protein through recognition-induced disassembly of the probe. On the basis of this strategy, we successfully developed three types of fluorescent probes that allow the detection of carbonic anhydrase, avidin, and trypsin via turn-on emission signals. It is anticipated that the present supramolecular approach may facilitate the development of new protein-specific switchable fluorescent probes that are useful for a wide range of applications, such as diagnosis and molecular imaging.
