(S)-nicotine (2a) in a preparation of whole rat brain. However, in a paradigm measuring the evoked release of [3H]dopamine from a preparation of rat striatum, there were differences in the agonist potencies and efficacies of these analogues relative to 2a. The differences in agonist potency observed between compounds of comparable binding potency may be due to differences in ligand interactions with various

Design and synthesis of pyrazolodihydropyrimidines as K(V)1.5 blockers led to the discovery of 7d as a potent and selective antagonist. This compound showed atrial selective prolongation of effective refractory period in rabbits and was selected for clinical development. (C) 2010 Elsevier Ltd. All rights reserved.
