optimization, and evaluation of a series of novel imidazopyridazine-based subtype-selective positive allosteric modulators (PAMs) for the GABAA ligand-gated ion channel are described. From a set of initial hits multiple subseries were designed and evaluated based on binding affinity and functional activity. As designing in the desired level of functionalselectivity proved difficult, a probability-based
The present invention relates to imidazopyridazine derivatives. More particularly, it relates to 4-(biphenyl-3-yl)-7H-imidazo[4,5-c]pyridazine derivatives of formula (I):
and pharmaceutically acceptable salts thereof, wherein R1, R2, R3, R4 and R5 are as defined in the description. The imidazopyridazine derivatives of the present invention modulate the activity of the GABAA receptor. They are useful in the treatment of a number of conditions, including pain.
