The present invention relates generally to a compound and/or a composition comprising the compound, useful for the treatment of, or prevention of, a Coronavirus (CoV) infection in particular SARS-CoV/SARS-CoV-1 or SARS-CoV-2.
The present invention relates to compounds that inhibit Protein Arginine N-Methyl Transferase 5 (PRMT5) activity. In particular, the present invention relates to compounds, pharmaceutical compositions and methods of use, such as methods of treating cancer using the compounds and pharmaceutical compositions of the present invention.
corresponding pyridylmagnesium chlorides at room temperature by treatment with iPrMgCl. The resulting Grignard reagents were quenched by various electrophiles to afford functionalized pyridines. The brominemagnesium exchange of some dibromopyridines was also studied.
Bromine–magnesium exchange using iPrMgCl in THF at roomtemperature on 2-, 3- and 4-bromopyridines allowed the synthesis of various functionalized pyridines. The methodology was successfully used for the synthesis of 4-azaxanthone. Moreover, single exchange reactions observed on 2,6-, 3,5-, 2,3- and 2,5-dibromopyridines, with complete regioselectivity in the case of 2,3- and 2,5-dibromopyridines, afforded

and n are as described herein, compositions including the compounds and methods of using the compounds. The compounds are useful, for example, as aldosterone synthase (CYP11B2 or CYP11B1) inhibitors for the treatment or prophylaxis of chronic kidney disease, congestive heart failure, hypertension, primary aldosteronism and Cushing syndrome.
A Modular Synthesis of Teraryl-Based α-Helix Mimetics, Part 2: Synthesis of 5-Pyridine Boronic Acid Pinacol Ester Building Blocks with Amino Acid Side Chains in 3-Position

general approach for the synthesis of 3,5‐disubstituted pyridine‐based boronic acid pinacol esters with amino acid side chains in the 3‐position (representing Phe, Leu, Ile, Lys, Asp, Asn) is presented and exploits the functional group tolerance of the Knochel–Grignard reagents. The buildingblocks have been used in a convergent in situ two‐step synthesis of teraryl α‐helix mimetics.
