Phospholipids self-assemble in bulk oils to form structures such as reverse micelles that can alter the microenvironment where chemical degradation reactions occur, such as lipid oxidation. In this study, we examined the influence of phospholipid reverse micelles on the activity of non-polar (α-tocopherol) and polar (Trolox) antioxidants in stripped soybean(More)
A model for rainbow trout (Oncorhynchus mykiss) estrogen receptor (rtERa) was built by homology with the human estrogen receptor (hERa). A high level of sequence conservation between the two receptors was found with 64% and 80% of identity and similarity, respectively. Selected endocrine disrupting chemicals were docked into the ligand binding domain (LBD)(More)
A series of 5-(1-aryl-4-piperazino)methyl-2-amino-2-oxazolines has been prepared and screened for antidepressant activity. Their lipophilic behaviour has been discussed in relation to the nature and the position of substituents on the aromatic ring. The influence of steric effects on the pharmacological activity has been investigated using experimental(More)
Platelet-activating factor (PAF) is a powerful phospholipid-derived autacoid involved in many physiopathological mechanisms. Many PAF antagonists have been synthesized and evaluated as therapeutic candidates. In a previous report, we have described an electronic pharmacophore of PAF antagonists using the molecular electrostatic potential. In the present(More)
PAF is a powerful phospholipid-derived autacoid involved in many physio-pathological mechanisms. Many PAF antagonists have been synthesized and assayed for therapeutic purposes. In this study, molecular electrostatic potential is used to compare the electronic properties of 48 'heterocyclic sp2 nitrogen' highly potent PAF antagonists, belonging to six(More)
If the geometrical pharmacophore of 5-HT3 receptor antagonists has been proposed by different authors, the electronic and lipophilic features of the ligands had to be precised. A 3-D QSAR study has enlightened the importance of three parameters derived from molecular electrostatic and molecular lipophilicity potentials. A multiple linear regression equation(More)
Shape complementarity, electrostatic and hydrophobic matching, were used to model drugs and receptors. From known experimental data on alpha1A/alpha2A-adrenergic ligands and alpha1A/alpha2A-adrenoceptors, a model for the ligand binding sites, based on the structure of bacteriorhodopsin as a template, was proposed and built. Agonists and antagonists have(More)
