Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. 13331-27-6, Name is 3-Nitrophenylboronic acid, molecular formula is C6H6BNO4, Category: naphthyridines, belongs to naphthyridine compound, is a common compound. In a patnet, author is de los Rios, Cristobal, once mentioned the new application about 13331-27-6.

1,8-Naphthyridine derivatives related to 17 (ITH4012), a neuroprotective compound reported by our research group, have been synthesized. In general, they have shown better inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) than most tacrine derivatives previously synthesized in our laboratory. The compounds presented an interesting neuroprotective profile in SH-SY5Y neuroblastoma cells stressed with rotenone/oligomycin A. Moreover, compound 14 (ethyl 5-amino-2-methy1-6,7,8,9-tetrahydrobenzo[b][1,8]naphthyridine-3-carboxylate) also caused protection in cells stressed with okadaic acid (OA) or amyloid beta 1-42 peptide (A beta(1-42)). Interestingly, compound 14 prevented the OA-induced PP2A inhibition, one of the enzymes implicated in tau dephosphorylation. This compound also exhibited neuroprotection against neurotoxicity elicited by oxygen and glucose deprivation in hippocampal slices. Because these stressors caused neuronal damage related to physiopathological hallmarks found in the brain of Alzheimer’s disease (AD) patients, we conclude that compound 14 deserves further in vivo studies in AD models to test its therapeutic potential in this disease.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. I hope my blog about 13331-27-6 is helpful to your research. Category: naphthyridines.

In an article, author is Shen, Yi-Fan, once mentioned the application of 92-70-6, Name is 3-Hydroxy-2-naphthoic acid. Now introduce a scientific discovery about this category, Synthetic Route of 92-70-6.

Two TADF emitters 2,7-di(9H-carbazole)-1,8-naphthyridine (Cz-ND) and 2,7-di(3,6-di-tert-butyl-9H-carbazole)-1,8-naphthyridine (tBuCz-ND) were designed and synthesized. Both of the emitters showed high thermal stabilities and strong blue emissions with high photoluminescence quantum yields, and also exhibited excellent TADF properties with small Delta E-ST values. Consequently, blue organic light-emitting diodes (OLEDs) based on Cz-ND and tBuCz-ND were fabricated, which could achieve maximum external quantum efficiencies (EQE(max)) of 15.3 and 20.9%, respectively. Moreover, the devices also exhibited relatively narrow band gaps at 79 and 75 nm with the CIE coordinates of (0.15, 0.17) and (0.15, 0.22), respectively.
