Chemistry is traditionally divided into organic and inorganic chemistry. Recommanded Product: 5′-(4-Carboxyphenyl)-[1,1′:3′,1”-terphenyl]-4,4”-dicarboxylic acid. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 50446-44-1
In this article a series of divalent and trivalent carbohydrate mimetics on the basis of an enantiopure aminopyran and of serinol is described. These aminopolyols are connected by amide bonds to carboxylic acid derived spacer units either by Schotten-Baumann acylation or by coupling employing HATU as reagent. The O-sulfation employing the SO3·DMF complex was optimized. It was crucial to follow this process by 700 MHz 1H NMR spectroscopy to ensure full conversion and to use a refined neutralization and purification protocol. Many of the compounds could not be tested as L-selectin inhibitor by SPR due to their insolubility in water, nevertheless, a divalent and a trivalent amide showed surprisingly good activities with IC50 values in the low micromolar range.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 5′-(4-Carboxyphenyl)-[1,1′:3′,1”-terphenyl]-4,4”-dicarboxylic acid, you can also check out more blogs about50446-44-1
