Abstract:
The effect of some new β-phenylethylamine derivatives on some parameters of the lipid metabolism and lipid peroxidation
was investigated. The research method used was based on inducing hyperlipidaemia in rats by administering orally 4% triton
in a dose of 400 mg/kg bw. The new compounds were tested against fenofibrate, the reference substance. The results have
shown that compounds coded C2 and A1 induced a decrease in the total cholesterol levels, that was higher than that
generated by the reference substance, compared to the control group with hyperlipidaemia. Furthermore, compounds coded
C2, A6 and C3 have lowered LDL-cholesterol levels more efficiently than fenofibrate, in the hyperlipidaemia control group.
All compounds except for C1 increased HDL-cholesterol levels more than the reference substance in the hyperlipidaemia
control group. All compounds lowered the malonyl dialdehyde liver concentration, as a biomarker of lipid peroxidation,
compared to the hyperlipemic control group. According to our results, the newly synthesized β-phenylethylamine derivatives
have a statistically significant positive impact on the parameters of the lipid metabolism, possibly due to a β3- adrenergic
receptors agonist mechanism.
