  Synthesis and methemoglobinemia-inducing properties of benzocaine isosteres designed as humane rodenticides

  摘要：

  A number of isosteres (oxadiazoles, thiadiazoles, tetrazoles and diazines) of benzocaine were prepared and evaluated for their capacity to induce methemoglobinemia-with a view to their possible application as humane pest control agents. It was found that an optimal lipophilicity for the formation of methemoglobin (metHb) in vitro existed within each series, with 1,2,4-oxadiazole 3 (metHb% = 61.0 +/- 3.6) and 1,3,4-oxadiazole 10 (metHb% = 52.4 +/- 0.9) demonstrating the greatest activity. Of the 5 candidates (compounds 3, 10, 11, 13 and 23) evaluated in vivo, failure to induce a lethal end-point at doses of 120 mg/kg was observed in all cases. Inadequate metabolic stability, particularly towards hepatic enzymes such as the CYPs, was postulated as one reason for their failure. (C) 2014 Elsevier Ltd. All rights reserved.

  Abstract Several 1,3,4-oxadiazoles were synthetized by cyclization of N,N'-diacylhydrazines catalyzed by palladium(O). Water formed during the reaction is responsible for the hydrolysis of the products. To avoid it, we introduced benzoic anhydride into the medium and obtained an increased yield of oxadiazoles.
