The invention provides named compounds of formula (I), wherein R4 is a N-substituted quinuclidine (I) pharmaceutical compositions containing them and a process for preparing the pharmaceutical compositions. Their use in therapy for’ the treatment of conditions mediated by M3 muscarinic receptors, such as chronic obstructive pulmonary disease is also disclosed.
Detailed analyses of the solution structure and exchange dynamics of two sets of homologous mono-amide triacetate lanthanide complexes (Ln = Eu, Gd) of cyclen have been undertaken. The complex [LnL1], bearing an N-linked CH2CH2NHCOâpyridyl moiety, forms mono-aqua (q
= 1) species in solution and the Gd complex undergoes rapid water exchange (kex
= 11 Ã 107 sâ1, 298 K) as a result of the steric destabilisation of the Lnâwater binding interaction. The homologous complex with a C-3 spacing chain, [LnL2], forms a q
= 0 species.
