Biological Activity

ki: 1.8, 15, 85 and 34 nm for delta, mu, epsilon and kappa receptoropioid receptors are heterogeneous and at least four types, mu,.delta, kappa and epsilon, are known to exist. currently, all clinically used opiates act through the mu receptor to induce analgesia; however, they also induce unwanted side effects such as respiratory depression, dependence, constipation and muscle rigidity.bw 373u86 is a novel, potent and selective nonpeptidic delta opioid receptor agonist.

in vitro

bw 373u86 was a potent delta receptor-selective ligand in receptor binding assays. the ki values were 1 .8 ± 0.4, 15 ± 3, 85 ± 4 and 34 ± 3 nm for delta, mu, epsilon and kappa receptor binding sites, respectively. bw 373u86 inhibited electncally evoked muscle contraction of mouse vas deferens with an ed50 value of 0.2 ± 0.06 nm [1].

in vivo

bw 373u86 inhibited the acoustic startle reflex after subcutaneous administration from 0.2- to 2-mg/kg doses in rats, and this inhibition was blocked by naltnndole. bw 373u86 also induced a dose-dependent increase of locomotor activity in rats at similar doses. this effect was inhibited by naltnndole [3].

Probes for narcotic receptor mediated phenomena. 23. Synthesis, opioid receptor binding, and bioassay of the highly selective δ agonist (+)-4- [(αR)-α-((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl)-3-methoxybenzyl]N,N- diethylbenzamide (SNC 80) and related novel nonpeptide δ opioid receptor ligands

The highly selective delta (δ) opioid receptor agonist SNC 80 [(+)-4- [(αR)-α-((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl)-3-methoxybenzyl]-N,N- diethylbenzamide, (+)-21] and novel optically pure derivatives were synthesized from the enantiomers of 1-allyl-trans-2,5-dimethylpiperazine (2). The piperazine (±)-2 was synthesized, and its enantiomers were obtained on a multigram scale in >99% optical purity by optical resolution of the racemate with the camphoric acids. The absolute configuration of (+)-2 was determined to be 2S,5R by X-ray analysis of the salt with (+)-camphoric acid. Since the chirality of the starting material was known, and the relative configuration of compounds (-)-21, (-)-22, and (+)-23 were obtained by single-crystal X- ray analysis, the assignment of the absolute stereochemistry of the entire series could be made. Radioreceptor binding studies in rat brain preparations showed that methyl ethers (+)-21 (SNC 80) and (-)-25 exhibited strong selectivity for rat δ receptors with low nanomolar affinity to 6 receptors and only micromolar affinity for rat mu (μ) opioid receptors. Compounds (- )-21, (-)-22, and (-)-23 showed micromolar affinities for δ opioid receptors. The unsubstituted derivative (+)-22 and the fluorinated derivative (-)-27 showed >2659- and >2105-fold δ/μ binding selectivity, respectively. The latter derivatives are the most selective ligands described in the new series. Studies with some of the compounds described in the isolated mouse vas deferens and guinea pig ileum bioassays revealed that all were agonists with different degrees of selectivity for the δ opioid receptor. These data show that (+)-21 and (+)-22 are potent δ receptor agonists and suggest that these compounds will be valuable tools for further study of the δ opioid receptor at the molecular level, including its function and role in analgesia and drug abuse.
