N-(3,5-Dichloro-4-(2,4,6-trichlorophenoxy)phenyl)benzenesulfonamide: A new dual-target inhibitor of mitochondrial complex II and complex III via structural simplification
Mitochondrial complexII and complexIII are two promising targets for the development of numerous pharmaceuticals and pesticides. Although tremendous inhibitors of either complexII or complexIII were identified, compounds which are capable of prohibiting the activities of both complexes have been rarely reported. Since multi-target drugs can interact with several drug targets simultaneously, we

Novel bicyclooxyphenyl ureas, such as 1-(bicyclooxyphenyl)-benzoyl ureas, are provided which exhibit pesticidal activity. The compositions are conveniently prepared by reacting an isocyanate with either an amide or a bicyclooxyaniline.
Succinate-cytochrome c reductase (SCR) is composed of a mixture of mitochondrial complex II (succinate-ubiquinone oxidoreductase) and complex III (cytochrome bc(1) 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.

N-(4-(2-chloro-4-(trifluoromethyl)phenoxy)phenyl)picolinamide as a new inhibitor of mitochondrial complex III: Synthesis, biological evaluation and computational simulations
of pharmaceuticals and fungicides. Due to the wide-spread use of complex III-inhibiting fungicides, a considerable increase of resistance has occurred worldwide. Therefore, inhibitors with novel scaffolds and potent activity against complex III are still in great demand. In this article, a new series of amide compounds bearing the diarylether scaffold were designed and prepared, followed by the biological
