ABSTRACT
|
|
|
| |
|
A unique tetrahydrofuran ether class of highly potent
α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor potentiators has
been identified using rational and structure-based drug design. An acyclic lead
compound, containing an ether-linked isopropylsulfonamide and biphenyl group,
was pharmacologically augmented by converting it to a conformationally
constrained tetrahydrofuran to improve key interactions with the human GluA2
ligand-binding domain. Subsequent replacement of the distal phenyl motif with
2-cyanothiophene to enhance its potency, selectivity, and metabolic stability
afforded
N-{(3S,4S)-4-[4-(5-cyano-2-thienyl)phenoxy]tetrahydrofuran-3-yl}propane-2-sulfonamide
(PF-04958242, 3), whose preclinical characterization suggests an adequate
therapeutic index, aided by low projected human oral pharmacokinetic
variability, for clinical studies exploring its ability to attenuate cognitive
deficits in patients with schizophrenia.
