We have determined that the muscarinic receptor can to a different degree accommodate either a halogen in the ortho, meta, or para position of one phenyl ring or the replacement of one phenyl ring with an alkyl group. Our in vitro competition studies show that the affinities lie within a 270-fold range, from the highest affinity compound, 3-quinuclidinyl alpha-hydro

    1-Azabicyclo[2.2.2]oct-3-yl alpha-hydroxy-alpha-(1-iodo-1-propen-3-yl)-alpha-phenylacetate (IQNP, 3), an analogue of QNB in which a phenyl ring has been replaced with an iodopropenyl substituent, was prepared and evaluated in vitro and in vivo for m-AChR selectivity and specificity. High specific activity [125]IQNP ([I-125]-3) was synthesized in greater than 60% yield utilizing an electrophilic iododestannylation reaction with hydrogen peroxide for the oxidation of iodide. In in vitro receptor binding studies, 3 demonstrated high affinity for M1 (K(i) = 0.78 nM), M2 (K(i) = 1.06 nM), and M3 (K(i) = 0.27 nM) subtypes. In vivo biodistribution studies in female rats [I-125]-3 demonstrated high uptake in areas rich in muscarinic receptors such as the brain (cortex and striatum) and the heart. Blocking studies were performed with a series of receptor specific agents and demonstrated that the uptake of [I-125]-3 was selective and specific for cerebral muscarinic receptor rich areas and that the binding to m-AChR is reversible. The high-yield preparation and specificity and selectivity of high specific activity [I-125]IQNP for muscarinic receptors suggest that this is an attractive new agent for potential imaging of cerebral receptors using single photon tomographic imaging (SPECT).

In contrast, iodine-125-labeled (E)-(-)-(-)-, (Z)-(-)-(-)-, and (Z)-(-)-(+)-1 have high uptake and retention in mAChR rich areas of the brain. It was also observed that (E)-(-)-(-)-IQNP demonstrated an apparent subtype selectivity in vivo with retention
