title: Hypocholesterolemic and hypolipidemic activity of some novel morpholine derivatives with antioxidant activity.
abstract: In this investigation, we study the synthesis and the evaluation of antioxidant and hypocholesterolemic activity of a number of 2-biphenylyl morpholine derivatives, which are structurally similar to some substituted morpholines possessing antioxidant activity, as well as to hypocholesterolemic 3-biaryl-quinuclidines. The novel derivatives are found to inhibit the ferrous/ascorbate induced lipid peroxidation of microsomal membrane lipids, the most potent derivative, 2-(4-biphenyl)-4-methyl-octahydro-1,4-benzoxazin-2-ol (compound 7), having an IC(50) value of 250 microM. In addition, these compounds demonstrate hypocholesterolemic and hypolipidemic action. The most active compound (7) decreases total cholesterol, low density lipoprotein, and triglycerides in plasma of Triton WR-1339 induced hyperlipidemic rats by 54%, 51%, and 49%, respectively, at 28 micromol/kg (ip). The above results indicate that the new molecules may be proven useful as leads for the design of novel compounds as potentially antiatherogenic factors.
