This new series was developed by lead optimization of a hit from an internal HTS campaign. Compound 3 is significantly more potent than the previously reported indole carboxylic acid 1 with an A549 whole cell IC 50 of 0.42 lM (50% FBS) and a human whole blood IC 50 of 1.3 lM. It exhibited a significant analgesic effect in a guinea pig hyperalgesia model when orally dosed at 30 and 100 mg/kg.

Research paper thumbnail of Optimization of a Tertiary Alcohol Series of Phosphodiesterase-4 (PDE4) Inhibitors:  Structure−Activity Relationship Related to PDE4 Inhibition and Human Ether-a-go-go Related Gene Potassium Channel Binding Affinity

Journal of Medicinal Chemistry, 2003

In addition to inhibitory potency against PDE4 and the lipopolysaccharide-induced production of TNFalpha in human whole blood, the binding affinity of these compounds for the human ether-a-go-go related gene (hERG) potassium channel (an in vitro measure for the potential to cause QTc prolongation) was assessed. Four key structural moieties in the molecule were studied, and the impact of the resulting modifications in modulating these activities was evaluated. From these studies, (+)-3d (L-869,298) was identified as an optimized structure with respect to PDE4 inhibitory potency, lack of binding affinity to the hERG potassium channel, and pharmacokinetic behavior. (+)-3d exhibited good in vivo efficacy in several models of pulmonary function with a wide therapeutic index with respect to emesis and prolongation of the QTc interval.
