Name: (6-Chloro-5-methylpyridin-3-yl)boronic acidOn March 27, 2014, Fontaine, Fanny; Hequet, Arnaud; Voisin-Chiret, Anne-Sophie; Bouillon, Alexandre; Lesnard, Aurelien; Cresteil, Thierry; Jolivalt, Claude; Rault, Sylvain published an article in Journal of Medicinal Chemistry. The article was 《First identification of boronic species as novel potential inhibitors of the Staphylococcus aureus NorA efflux pump》. The article mentions the following:
Overexpression of efflux pumps is an important mechanism of bacterial resistance that results in the extrusion of antimicrobial agents outside the bacterial cell. Inhibition of such pumps appears to be a promising strategy that could restore the potency of existing antibiotics. The NorA efflux pump of Staphylococcus aureus confers resistance to a wide range of unrelated substrates, such as hydrophilic fluoroquinolones, leading to a multidrug-resistance phenotype. Here, 150 heterocyclic boronic species were evaluated for their activity against susceptible and resistant strains of S. aureus. Twenty-four hit compounds, although inactive when tested alone, were found to potentiate ciprofloxacin activity by a 4-fold increase at concentrations ranging from 0.5 to 8 μg/mL against S. aureus 1199B, which overexpresses NorA. Boron-free analogs showed no biol. activity, thus revealing that the boron atom is crucial for biol. activity. This work describes the first reported efflux pump inhibitory activity of boronic acid derivatives In the experiment, the researchers used (6-Chloro-5-methylpyridin-3-yl)boronic acid(cas: 1003043-40-0Name: (6-Chloro-5-methylpyridin-3-yl)boronic acid)
(6-Chloro-5-methylpyridin-3-yl)boronic acid(cas: 1003043-40-0) belongs to pyridine. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Additionally, pyridine-based natural products continue to be discovered and studied for their properties and to understand their biosynthesis.Name: (6-Chloro-5-methylpyridin-3-yl)boronic acid
