Respiratory chain succinate-ubiquinone oxidoreductase (SQR or complex II) and ubihydroquinone-cytochrome (cyt) c oxidoreductase (cyt bc1 or complex III) have been demonstrated as the promising targets of numerous antibiotics and fungicides. As a continuation of our research work on the development of new fungicides, a series of 1,2,4-triazole-1,3-disulfonamide derivatives with dual functions targeting both SQR and cyt bc1 were designed and synthesized by coupling diverse diphenyl ether moieties with triazolesulfonamide units. These newly synthesized compounds were characterized by elemental analyses, 1H NMR and ESI-MS spectrometry. The in vitro assay indicated that most of the synthesized compounds displayed good inhibition against porcine succinate-cytochrome reductase (SCR) with IC50 values ranging from 3.2 to 81.8 μM, revealing much higher activity than that of the commercial control amisulbrom whose IC50 value is 93.0 μM. Further evaluation against the respective SQR and cyt bc1 indicated that most compounds exhibited SQR-inhibiting activity as well as cyt bc1-inhibiting activity, but the inhibition potency against SQR is much higher than that against cyt bc1, showing that the SCR inhibition might be contributed greatly by the SQR inhibition. The further antibacterial evaluation against Xanthomonas oryzae pv. oryzae revealed that four compounds showed excellent potency at the concentration of 20 μg mL-1. In particular, compounds 6h and 6j exhibited much better antibacterial activity than the commercial control bismerthiazol in terms of their EC50. Impressively, 6j has an EC90 of 33.62 μg mL-1, more than 10-fold higher than that of bismerthiazol.

Synthesis of diaryl ethers, diaryl thioethers, and diarylamines mediated by potassium fluoride-alumina and 18-crown-6: Expansion of scope and utility

An efficient alternative to the Ullmann ether synthesis of diaryl ethers, diaryl thioethers, and diarylamines involving the S(N)Ar addition of a phenol, thiophenol, or aniline to an appropriate aryl halide, mediated by potassium-fluoride alumina and 18-crown-6 in acetonitrile or DMSO, is described. Expansion of the reaction conditions to include DMSO as solvent has resulted in a far greater range of substitution patterns permitted on the electrophile. For example, it was found that electronically unfavorable 3- chlorobenzonitrile could be condensed with 3-methoxyphenol to form the corresponding diaryl ether in 66% yield, a combination not normally amenable to Ullmann coupling. Electron-withdrawing groups present on the electrophile may be as diverse as nitro, cyano, formyl, acetyl, ester, amide, and even aryl. The method features a simple reaction procedure that provides products in generally good to excellent purified yields.
