Methylation of imidazoline related compounds leads to loss of α2-adrenoceptor affinity. Synthesis and biological evaluation of selective I1 imidazoline receptor ligands
Methylated analogues of imidazoline relatedcompounds (IRC) were prepared; their abilities to bind I1 imidazoline receptors (I1Rs), I2 imidazoline binding sites (I2BS) and α2-adrenoceptor subtypes (α2ARs) were assessed. Methylation of the heterocyclic moiety of IRC resulted in a significant loss of α2AR affinity. Amongst the selective ligands obtained, LNP 630 (4) constitutes the first highly selective

The invention relates to a group of hydronopol derivatives which are agonists on human ORL1 (nociceptin) receptors. The invention also relates to the preparation of these compounds, to pharmaceutical compositions containing a pharmacologically active amount of at least one of these novel hydronopol derivatives as an active ingredient, as well as to the use of these pharmaceutical compositions for the treatment of disorders in which ORL1 receptors are involved.
The invention relates to compounds of the general formula (1)
wherein the symbols have the meanings as given in the description.
Treatment of formamides with 2-chloro-3-ethylbenzoxazolium tetrafluoroborate affords various isocyanides in good yields at room temperature in neutral media.

ibuprofen derivatives were synthesized starting from ibuprofen. Their chemical structure was confirmed by spectral data. All the compounds were tested for their COX inhibitory activity. RESULTS The best COX-2 activity and selectivity were obtained with compounds 5c and 5d, which were subjected to further in vivo testing (carrageenan-induced paw edema, rat serum PGE2, TNF- α and IL-6, hot plate latency test)
