Caractérisation de nouveaux analogues des cannabinoides
This thesis aims to assess the pharmacological effects of new synthetic cannabinoid analogs. A long-standing goal in cannabinoid research has been the discovery of potent synthetic analogs of the natural substances that might be developed as clinically useful drugs. This requires, among other things, that they be free of the psychotropic effects that characterize the recreational use of Cannabis. An important driving force for this goal is the long history of the use of Cannabis as a medicinal agent especially in the treatment of pain and inflammation. Among the many pharmacological effects of cannabinoids, two are of great therapeutic value: the anti-proliferative effect on tumor cells and anti-angiogenic effect. In this thesis, the study of these two effects has been conducted on tumoral and endothelial culture cell. The proliferation tests on both types of cells showed no cytotoxicity. This allowed further study of the anti-angiogenic effect, and ended the study of anti-tumoral effect. Inhibition of angiogenesis has been investigated by performing recolonization tests of a denuded area on endothelial cell monolayer and microtubules formation tests on gel matrix. This effect could not be evaluated because of contamination problems; however, some molecules show anti-migration effects. The absence of cytotoxicity and structural analogy with -tetrahydrocannabinol encourages the investigation in pharmacological effects of these new synthetic molecules. It would also be interesting to study in a doctoral thesis, the molecular mechanisms of action involved.
