  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.

  A convenient one pot method for the synthesis of 2,5-disubstituted 1,3,4-oxadiazoles from acids and acyl hydrazides is reported. Acid activation with CDI, followed by coupling with the desired acylhydrazide and dehydration in the same pot with Ph3P and CBr4 affords the corresponding 1,3,4-oxadiazoles in good yield. The scope of the acid and acylhydrazide components is presented.

  据报道，一种方便的一锅法从酸和酰基酰肼合成2，5-二取代的1,3,4-恶二唑。用CDI进行酸活化，然后与所需的酰肼偶联，并在同一罐中用Ph 3 P和CBr 4脱水，得到相应的1,3,4-恶二唑，收率很高。给出了酸和酰肼组分的范围。
