Design, Synthesis, and Biological Evaluation of Novel Fluorescent Probes Targeting the 18-kDa Translocator Protein

A series of fluorescent probes from the 6-chloro-2-phenylimidazo[1,2-a]pyridine-3-yl acetamides ligands featuring the 7-nitro-2-oxa-1,3-diazol-4-yl (NBD) moiety has been synthesized and biologically evaluated for their fluorescence properties and for thei

Novel codrugs with GABAergic activity for dopamine delivery in the brain

This study investigates the use of codrugs of the GABAergic agent 2-phenyl-imidazo[1,2-a]pyridinacetamide and dopamine (DA) or ethyl ester L-Dopa (LD) as a strategy to deliver DA and simultaneously activate GABA-receptors in the brain. For this purpose, both DA and LD ethyl ester were linked by carbamate bond to imidazo[1,2-a]pyridine acetamide moieties to yield two DA- and two LD-imidazopyridine derivatives. These compounds were evaluated in vitro to assess their stability, binding affinities and cell membrane transport, and in vivo to assess their bio-availability via microdialysis studies. The two DA derivatives were adequately stable in buffered solution, but underwent cleavage in diluted human serum. By contrast, the LD derivatives were unstable in buffered solution. Receptor binding studies showed that the DA-imidazopyridine carbamates had binding affinity for benzodiazepine receptors in the nanomolar range. Brain microdialysis experiments indicated that intraperitoneal administration of the DA derivatives sustained DA levels in rat striatum over a 4-h period. These results suggest that DA-imidazopyridine carbamates are new DA codrugs with potential application for DA replacement therapy.

A structure-activity relationship study of the affinity of selected imidazo[1,2-a]pyridine derivatives, congeners of zolpidem, for the ω1-subtype of the benzodiazepine receptor

A series of 6-substituted 2-aryl-N,N-dimethylimidazol [1,2-a]pyridine-3-acetamides, congeners of zolpidem and alpidem, was synthesized and tested in vitro for binding with the benzodiazepine receptor in the competition with 3H-zolpidem as an ω1-selective radioligand. Molecular electrostatic potential (MEP) and the HOMO and LUMO energies were calculated for the compounds by semi-empirical quantum chemistry methods. The lipophilicity parameter of the compounds, expressed as the logarithm of the octanol-water partition coefficient (log P), was calculated; alternatively, standard values of the Hansch hydrophobic substituent constants π were used. In agreement with earlier investigations on the benzodiazepine receptor ligands with a high preference for the ω1-subtype, a quantitative correlation of the biological data with molecular parameters has revealed a significant dependence (r=0.954) of the binding affinity (IC50) on the deepest MEP minimum, in this case associated with the amide carbonyl oxygen atom. The lipophilicity parameters were found to be of lower significance.
