摘要

In our ongoing program aimed at the design, synthesis, and biological evaluation of novel cannabinoid receptor ligands derived from olivetol and hexyl-resorcinol, we have designed a structural model for new derivatives on the basis of a previous study. Here we report the synthesis, binding, and molecular modeling studies of new potent compounds with high affinity toward CB_1 and CB_2 receptors. Compounds with amidic 'heads' with alkyloxy chains varying in length from 8 to 12 carbon atoms showed nanomolar affinity for both receptors, depending on the type of aromatic backbone. Two of the new compounds, although not very potent, exhibit selectivity for CB_1 receptors (CB_1/CB_2 = 0.07 and 0.08, respectively). Molecular modeling studies fitted this new class of cannabinoid ligands into a CB_1 receptor model, and the qualitative analysis of the results was in general agreement with the CB_1 affinity constants observed experimentally for these derivatives.
