The present invention relates to the synthesis and the evaluation of the antioxidant, hypocholesterolemic and hypolipidemic activity of substituted morpholine derivatives of formula (I) in which R1=CH2CH3, R2=CH3, R3, R4=H, R5=C6H5 (compound 1) or R1=CH2CH2CH2ONO2, R2=CH3, R3, R4=H, R5=C6H5 (compound 2) or R1=H, R2-R3=(CH2)4, R4=H, R5=C6H5 (compound 3) or R1=CH2CH2CH3, R2-R3=(CH2)4, R4=H, R5=C6H5 (compound 4) or R1=CH2CH2CH2ONO2, R2-R3=(CH2)4, R4=H, R5=C6H5 (compound 5) or R1=H, R2=CH3, R3-R4=(CH2)4, R5=C6H5 (compound 6) or R1=CH2CH2CH3, R2=CH3, R3-R4=(CH2)4, R5=C6H5 (compound 7) or R1=CH2CH2CH2ONO2, R2=CH3, R3-R4=(CH2)4, R5=C6H5 (compound 8) or R1=CH2CH2CH2ONO2, R2=CH3, R3, R4=H, R5=H (compound 9) or R1=H, R2=p-NO2-C6H4-CH2CH2, R3, R4=H, R5=C6H5 (compound 10). The 2-hydroxy- morpholine derivatives 3, 6 and 10 are synthesised by the reaction of the appropriate aminoalcohol (22 mmol) and the 2-bromo-4-phenylacetophenone or the 2-bromoacetophenone (10 mmol) in ether and acetone for 15 hours at room temperature. The 2-alkoxy derivatives 1, 4 and 7 are synthesised by the reaction of the respective 2-hydroxy derivative with the appropriate alcohol, in acid medium and reflux. Compounds 2, 5, 8 and 9 are synthesised by the reaction of the respective 2-hydroxy derivative with the 3-bromopropanol in acidic medium and reflux. The 2-(3-bromopropoxy) derivatives then reacted with silver nitrate in acetonitrile and reflux. The compounds of formula (I) decrease significantly total cholesterol, triglyceride and LDL-cholesterol levels in plasma. The compounds of formula (I) possess potent antioxidant activity. The compounds of formula (I) with the above properties could be useful to the treatment of hypercholesterolemia, hyperlipidemia and atheromatosis.
