Development of the First Potential Covalent Inhibitors of Anandamide Cellular Uptake
摘要:
On the basis of the chemical structures of two previously developed metabolically stable and relatively potent inhibitors of anandamide uptake, OMDM-1,2, two series of potential covalent inhibitors of anandamide cellular reuptake, which might be used for the molecular characterization of the protein(s) involved in the membrane transport of endocannabinoids, have been designed and synthesized. Most of the compounds inhibited uptake to a varied extent and in a generally enantio-sensitive manner when co-incubated with [C-14]anandamide, but only three of them, the photoactivatable 1a (OMDM-37), 1b (OMDM-39), and 8 (Lo395), also produced a significant inhibition of uptake following the preincubation only of the cells, and this effect was significantly enhanced following UV exposure only in the case of 8. None of the new compounds inhibited [C-14]anandamide hydrolysis with IC50 < 50 mu M, except for 1b.

oleic acids derivatives are synthesized to elucidate the functions of specific activation of protein kinase C (PKC) with oleic acid. The synthetic route is based on the alkylation of phenolic derivative with oleic acid equivalent and the post-functionalization of the compound to achieve radiolabeling. Several compounds have biologicalactivity for PKC with similar efficacy with that of oleic acid. The
