Phenylboronic acid or benzeneboronic acid, abbreviated as PhB(OH) 2 where Ph is the phenyl group C 6 H 5 - and B(OH) 2 is a boronic acid containing a phenyl substituent and two hydroxyl groups attached to boron. Phenylboronic acid is a white powder and is commonly used in organic synthesis.
4-Nonylphenylboronic acid is a potent and selective inhibitor of the enzyme fatty acid amide hydrolase (FAAH), with an IC 50 of 9.1nM, and 870x selectivity for FAAH over the related enzyme MAGL, which it inhibits with an IC 50 of 7900nM. [1]
Basic heteroaromatic boronic acids (boronic acids that contain a basic nitrogen atom, such as 2-pyridine boronic acid) display additional protodeboronation mechanisms. [4] A key finding shows the speciation of basic heteroaromatic boronic acids to be analogous to that of simple amino acids , with zwitterionic species forming under neutral pH ...
4-Formylphenyl boronic acid crystallizes in colorless needles [2] or is obtained as an odorless, whitish powder, which dissolves little in cold but better in hot water. The compound is quite stable [4] and readily forms dimers and cyclic trimeric anhydrides, which complicate purification and tend to protodeboronize, a secondary reaction that occurs frequently in the Suzuki coupling, with ...
Boronic acids are known to bind to active site serines and are part of inhibitors for porcine pancreatic lipase, [2] subtilisin [3] and the protease Kex2. [4] Furthermore, boronic acid derivatives constitute a class of inhibitors for human acyl-protein thioesterase 1 and 2, which are cancer drug targets within the Ras cycle. [5]
Sonidegib is administered by mouth.Common side effects include muscle spasms, hair loss, fatigue, abdominal pain, nausea, headache, and weight loss. [1]Sonidegib binds to and inhibits smoothened to inhibit activation of the Hedgehog pathway.
Etofenamate is a nonsteroidal anti-inflammatory drug (NSAID) used for the treatment of joint and muscular pain. [1] It is available for topical application as a cream, a gel or as a spray.
Any sulfonamide can be considered as derived from a sulfonic acid by replacing a hydroxyl group (−OH) with an amine group. In medicine, the term "sulfonamide" is sometimes used as a synonym for sulfa drug, a derivative or variation of sulfanilamide. The first sulfonamide was discovered in Germany in 1932. [2]
