A green and facile approach for synthesis of nitro heteroaromatics in water

A convenient and green method for the oxidation of nitrogen-rich heterocyclic amines to nitro-substituted heteroaromatics using potassium peroxymonosulfate (2KHSO5·KHSO4·K 2SO4, Oxone) in water was developed. This method has several advantages over previous methods: operational simplicity, safety, inexpensive reagents, the use of H2O as the sole solvent, and mild conditions. The utility of the present oxidative system was demonstrated by the synthesis of the important energetic compounds 3,4,5-trinitro-1H-pyrazole (TNP) and 5-amino-3-nitro-1H-1,2,4-triazole (ANTA).

N-benzoylpyrazoles are novel small-molecule inhibitors of human neutrophil elastase

Human neutrophil elastase (NE) plays an important role in the pathogenesis of pulmonary disease. Using high-throughput chemolibrary screening, we identified 10 N-benzoylpyrazole derivatives that were potent NE inhibitors. Nine additional NE inhibitors were identified through further screening of N-benzoylpyrazole analogues. Evaluation of inhibitory activity against a range of proteases showed high specificity for NE, although several derivatives were also potent inhibitors of chymotrypsin. Analysis of reaction kinetics and inhibitor stability revealed that N-benzoylpyrazoles were pseudoirreversible competitive inhibitors of NE. Structure-activity relationship (SAR) analysis demonstrated that modification of N-benzoylpyrazole ring substituents modulated enzyme selectivity and potency. Furthermore, molecular modeling of the binding of selected active and inactive compounds to the NE active site revealed that active compounds fit well into the catalytic site, whereas inactive derivatives contained substituents or conformations that hindered binding or accessibility to the catalytic residues. Thus, N-benzoylpyrazole derivatives represent novel structural templates that can be utilized for further development of efficacious NE inhibitors.
