RESUMO
In this data article, we have designed a simple and facile protocol for copper-mediated synthesis of new 4-aryloxy-N-arylanilines under mild reaction conditions. The general information and synthetic procedures of all the target compounds were provided, and they were fully characterized by Nuclear Magnetic Resonance (NMR, including 1H NMR and 13C NMR), melting point measurements, and High-Resolution Mass Spectroscopy (HRMS). Furthermore, the inhibitory activities of these compounds against succinate-cytochrome c reductase (SCR) were evaluated, and the methods and procedures of enzyme inhibition experiments were also recorded in this data article. This article is related to "Synthesis of new 4-aryloxy-N-arylanilines and their inhibitory activities against succinate-cytochrome c reductase" (Cheng et al., 2018) [1].
RESUMO
Succinate-cytochrome c reductase (SCR) is composed of a mixture of mitochondrial complex II (succinate-ubiquinone oxidoreductase) and complex III (cytochrome bc1 complex). Meanwhile, complexes II and III are two promising targets of numerous antibiotics and fungicides. With an aim to identify new lead structures for SCR, complex II or III, a new series of 4-aryloxy-N-arylanilines were synthesized by introducing a 4-aryloxy phenyl group as one of the aryl groups in diaryl amines. With the economic Cu(OAc)2·H2O as the optimal copper promoter, a simple and facile protocol was utilized to afford 24 target products in 56-93% yields. Furthermore, extensive screening results suggested variable inhibitory activities of these compounds against SCR. Exceptionally, compounds 7k-7n showed excellent inhibition potency with their IC50 values in the nanomolar range, demonstrating higher potency than the commercial controls (penthiopyrad and azoxystrobin) by over one order of magnitude.
