  Biarylcarboxylic Acids and -amides:  Inhibition of Phosphodiesterase Type IV versus [³H]Rolipram Binding Activity and Their Relationship to Emetic Behavior in the Ferret

  摘要：

  In addition to having desirable inhibitory effects on inflammation, anaphylaxis, and smooth muscle contraction, PDE-IV inhibitors also produce undesirable side effects including nausea and vomiting. In general, compounds that inhibit PDE-IV also potently displace [H-3]rolipram from a high-affinity binding site in rat cortex.(1,2) While this binding site has not been identified, it has been proposed to be an allosteric binding site on the PDE-IV enzyme.(3) Preliminary studies have suggested that the emetic potency of PDE-IV inhibitors is correlated with affinity for the brain rolipram binding site rather than potency at inhibiting PDE-IV enzyme activity. Efforts to eliminate the emetic potential of PDE-IV inhibitors were directed toward developing compounds with decreased [H-3]rolipram binding affinity while retaining PDE-IV potency. Thus, a novel series of 4-(3-alkoxy-4-methoxyphenyl)benzoic acids and their corresponding carboxamides were prepared and evaluated for their PDE-IV inhibitory and rolipram binding site properties. Modification of the catechol ether moiety led to phenylbutoxy and phenylpentoxy analogues that provided the desired actitivity profile. Specifically, 4-[3-(5-phenylpentoxy)-4-methoxyphenyl]-2-methylbenzoic acid, 18, was found to exhibit potent PDE-IV inhibitory activity (IC50 0.41 mu M) and possessed 400 times weaker activity than rolipram for the [H-3]rolipram binding site. In vivo, compound 18 was efficacious in the guinea pig aerosolized antigen induced airway obstruction assay (ED(50) 8.8 mg/kg, po) and demonstrated a significant reduction in emetic side effects (ferret, 20% emesis at 30 mg/kg, po).

  Tumor necrosis factor-alpha (TNF-alpha) has been implicated as a key mediator in the progression of rheumatoid arthritis. Inhibitors of phosphodiesterase IV (PDE IV) have been shown to inhibit the production of TNF-alpha by elevating intracellular levels of cyclic adenosine monophosphate (cAMP). Our efforts in a series of biarylcarboxamides have led to the identification of 8j (CP-353,164) as a potent inhibitor of PDE IV and TNF-alpha production. (C) 1997 Elsevier Science Ltd.
