The chemistry of the opioid receptor binding sites

Abstract: Since the discovery of the opioid receptors and their endogenous ligands an immense research work has been devoted to the exploration of their specificity, the mechanism of ligand binding and ligand-receptor interactions. One of the main goals has been the location and characterization of the binding sites. The present review compiles the results achieved in this field in the last quarter of a century, and puts some questions concerning the success of these efforts.

“…Well‐known and typical functionality investigations include receptor binding assays, cell and tissue studies, penetration of biological barriers and tissue distribution and uptake. In radioligand binding studies, receptor affinity or selectivity is studied to characterize the receptors or ligands pharmacologically1–8. Studies involving the penetration of biological barriers are often focused on the transport of drugs through the blood–brain barrier (BBB).…”

“…Estruturalmente, os receptores opióides apresentam-se dispostos em sete domínios transmembranares conectados por três alças ou loops intracelulares e três extracelulares, com um domínio C-terminal intracelular e um domínio N-terminal extracelular (Figura 6) (Pugsley, 2002;Medzihradszky, 2003). Na comparação dos mesmos, evidencia-se similaridade entre os domínios transmembranares e alças intracelulares, sendo que essas estruturas se apresentam até mesmo idênticas em algumas regiões.…”

“…Na comparação dos mesmos, evidencia-se similaridade entre os domínios transmembranares e alças intracelulares, sendo que essas estruturas se apresentam até mesmo idênticas em algumas regiões. No entanto, existem divergências significativas na estrutura dos segmentos C e N-terminal, bem como na estrutura dos domínios 4 e 5 (Medzihradszky, 2003). Quanto à localização, os receptores difundem-se em todo SNC e SNP, bem como, em todos os tecidos periféricos.…”
