Objective: The objective was to study the acute toxicity of (Z)-1-benzhydryl-4-cinnamylpiperazine derivatives (1a-c) using Swiss Albino mice.
Methods: The acute oral and dermal toxicity studies were carried out based on OECD guidelines by adopting fixed dosage method (the limit dose
is 2000 mg/kg body weight of test animal in case of dermal toxicity and 5000 mg/kg in oral toxicity). Toxicity and mortality rates were studied at
intervals of 6 hrs and 14 hrs after administration of test compounds for 14 days.
Results: (Z)-1-benzhydryl-4-cinnamyl piperazine derivatives (1a-c) at oral treatment of 5000 mg/kg BW and dermal toxicity study of 2000 mg/kg
BW did not show any pronounced toxicity indicating their potential use for therapeutic purposes.
Conclusion: All compounds 1a-c did not cause any mortality or changes in general behavior of the test animals at oral treatment of 5000 mg/kg BW
indicating no conspicuous toxicity at the highest dose administered.
Keywords: (Z)-1-benzhydryl-4-cinnamyl piperazine derivatives, Acute toxicity, Albino mice, Cinnarizine, Flunarizine.
