AMIDE DERIVATIVE AND DRUG CONTAINING SAME

摘要

[Problem] To provide a novel amide derivative having greater safety and having superior phosphodiesterase 4 inhibition. [Solution] The novel amide derivative, which is represented by general formula (1), has strong PDE 4 inhibiting activity, and is rapidly metabolized in the body, thus having an activity that attenuates, and so it is possible to suppress systemic adverse effects from arising. From said characteristics, the compound of the present invention is particularly suited to localized administration. In formula (1), A represents a condensed aromatic heterocyclic group represented by formula (a) or formula (b).
