  (EN) A class of N-substituted piperazine, piperidine and tetrahydropyridine derivatives of formula (I), further substituted at the 4-position by an optionally substituted aryl-alkyl or heteroaryl-alkyl moiety, are selective agonists of 5-HT1-like receptors, being potent agonists of the human 5-HT1D$g(a) receptor subtype relative to the 5-HT1D$g(b) subtype; they are therefore useful in the treatment and/or prevention of clinical conditions, in particular migraine and associated disorders, for which a subtype-selective agonist of 5-HT1D receptors is indicated, whilst eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT1D receptor agonists. In formula (I) Z represents hydrogen, halogen, cyano, nitro, trifluoromethyl, -OR5, -OCOR5, -OCONR5R6, -OCH2CN, -OCH2CONR5R6, -SR5, -SOR5, SO2R5, -SO2NR5R6, -NR5R6, -NR5COR6, -NR5CO2R6, -NR5SO2R6, -COR5, -CO2R5, -CONR5R6, or a group of formula (a), (b), (c) or (d).(FR) Une classe de dérivés de pipérazine, pipéridine et tétrahydropyridine, N-substitués, de la formule (I), à substitution ultérieure au niveau de la position 4 par une fraction aryl-alkyle ou hétéroaryl-alkyle éventuellement substituée, constitue des agonistes sélectifs des récepteurs de type 5-HT1, car ils sont des agonistes puissants du sous-type de récepteur humain 5-HT1D$g(a) par rapport au sous-type 5-HT1D$g(b); en conséquence, ces dérivés sont utiles dans le traitement et/ou la prévention d'états cliniques, notamment de la migraine et des troubles qui lui sont associés, dans lesquels un agoniste sélectif du sous-type de récepteurs 5-HT1D est indiqué, tandis qu'ils provoquent moins d'effets secondaires, notamment des complications cardio-vasculaires indésirables, que les agonistes non sélectifs de sous-type de récepteurs 5-HT1D.

  Multidrug resistance mediated by P-glycoprotein (Pgp) or multidrug-resistance-associated protein (MRP) remains a major obstacle for successful treatment of cancer. Inhibition of Pgp and MRP transport is important for high efficacy of anticancer drugs. While several Pgp inhibitors have entered clinical trials, the development of specific MRP1 inhibitors is still in its infancy. In our screening program, we have identified a pyrrolopyrimidine (4) as a novel and selective MRP1 inhibitor. Subsequent SAR work on the 4-position of the template revealed the phenethylpiperazine side chain as a potent replacement of the benzylthio group of the lead molecule. Introduction of groups at the 2-position seems to have no detrimental effect on activity. Modifications to the nitrile group at the 7-position resulted in the identification of analogues with groups, such as amides, with superior pharmacokinetic profiles. In vivo efficacy has been demonstrated by xenograft studies on selected compounds.

  In our continued effort to identify selective MRP1 modulators, we have developed two novel templates, 3 and 4, through rational drug design by identifying the key pharmacophore interaction at the 7-position of the pyrrolopyrimidine template 1. Further synthesis and SAR work on these novel templates gave a number of potent MRP1 modulators with great selectivity against Pgp. Additional studies to reduce the CYP3A4 inhibition are also reported. Several compounds of these classes were subjected to in vivo xenograft studies and in vivo efficacies were demonstrated.
