Di- and trisubstituted pyrazolo[1,5-a]pyridine derivatives: synthesis, dopamine receptor binding and ligand efficacy
摘要:
Based on the lead molecule FAUC 113, a series of di- and trisubstituted pyrazolo[1,5-a]pyridine derivatives was synthesized and investigated for their dopamine receptor binding profile. The carbonitrile 11a (FAUC 327) showed excellent pharmacological properties combining high D4 affinity (K-i = 1.5 nM) and selectivity with significant intrinsic activity (31%) in low nanomolar concentrations (EC50 = 1.5 nM), (C) 2002 Elsevier Science Ltd.

Azaindole derivatives with high affinity for the dopamine D4 receptor: Synthesis, ligand binding studies and comparison of molecular electrostatic potential maps
摘要:
Piperazinylmethyl substituted pyrazolo[1,5-a]pyridines and related heterocycles were synthesized and found to recognize selectively the dopamine D4 receptor. For the most potent derivative 10d a Ki value of 2.0 nM was observed. SAR studies including the comparison of molecular isopotential surfaces were performed. (C) 1998 Elsevier Science Ltd.
