Synthesis, Properties, and Reactivity of Bis-BN Phenanthrenes: Stepwise Bromination of the Main Scaffold

Two bis-BN phenanthrenes have been synthesized. Their photophysical properties are different from those of the reported mono-BN phenanthrenes. Moreover, the stepwise bromination of bis-BN phenanthrene 8 gave a series of brominated bis-BN phenanthrenes, with all of the mono-, di-, tri-, and tetrabrominated bis-BN phenanthrenes being successfully isolated and characterized. In addition, preliminary results showed that mono- and dibrominated species can be further functionalized by cross-coupling reactions.

Synthesis, anti-inflammatory, p38alpha MAP kinase inhibitory activities and molecular docking studies of quinoxaline derivatives containing triazole moiety

A new series of 3-[2-(5-mercapto-4-phenyl-4H-1,2,4-traiazol-3-yl)ethyl] quinoxalin-2(1H)-one (5a-v) derivatives was synthesized and subjected to in vitro evaluation for anti-inflammatory activity (BSA anti-denaturation assay) and p38alpha MAPK inhibition. Few selected compounds (5a, 5e, 5f, 5g, 5h, 5l, 5q and 5u) were studied for their in vivo anti-inflammatory activity, ulcerogenicity and lipid peroxidation potential. Compounds 5e and 5f were found to be the most active in the series showing 83.45% and 84.15% anti-inflammatory activity respectively when compared to diclofenac sodium (83.22%). They were also found to have low ulcerogenic potential and lipid peroxidation. The p38alpha MAP kinase inhibition of the compounds 5e and 5f was also found to be slightly better than the standard SB 203580. The compounds were also docked against p38alpha MAP kinase enzyme in order to predict their binding mode. Compounds 5e and 5f showed stronger binding with an additional hydrogen bond interaction with ASP-168 which was not observed in SB 203580.

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: 7712-28-9, you can also check out more blogs about7712-28-9

Direct C?H difluoromethylation of heterocycles via organic photoredox catalysis

The discovery of modern medicine relies on the sustainable development of synthetic methodologies to meet the needs associated with drug molecular design. Heterocycles containing difluoromethyl groups are an emerging but scarcely investigated class of organofluoro molecules with potential applications in pharmaceutical, agricultural and material science. Herein, we developed an organophotocatalytic direct difluoromethylation of heterocycles using O2 as a green oxidant. The C?H oxidative difluoromethylation obviates the need for pre-functionalization of the substrates, metals and additives. The operationally straightforward method enriches the efficient synthesis of many difluoromethylated heterocycles in moderate to excellent yields. The direct difluoromethylation of pharmaceutical moleculars demonstrates the practicability of this methodology to late-stage drug development. Moreover, 2?-deoxy-5-difluoromethyluridine (F2TDR) exhibits promising activity against some cancer cell lines, indicating that the difluoromethylation methodology might provide assistance for drug discovery.
