PDE4 inhibitors are a validated approach as anti-inflammatory agents but are limited by systemic side effects including emesis. We report a soft-drug strategy incorporating a carboxylic ester group into boron-containing PDE4 inhibitors leading to the discovery of a series of benzoxaborole compounds with good potency (for example IC(50) = 47 nM of compound 2) and low emetic activity. These compounds are intended for dermatological use further limiting possible systemic side effects. (C) 2010 Elsevier Ltd. All rights reserved.
