6,7-Dihydro-5H-pyrrolo[1,2-a] imidazoles as potent and selective alpha1A adrenoceptor partial agonists.
Novel pyrroloimidazoles have been identified as potent partial agonists of the alpha(1A) adrenergic receptor, with good selectivity over the alpha(1B), alpha(1D) and alpha(2A) receptor subtypes. Pyrimidine 19 possessed attractive CNS drug-like properties with good membrane permeability and no evidence for P-gp mediated efflux.
