Abstract

This invention relates to pyrazolopyridyl compounds of the structural formula:

or their pharmaceutically acceptable salts, wherein the variable are defined herein. The inventive compounds selectively inhibit aldosterone synthase. This invention also provides for pharmaceutical compositions comprising the compounds of Formula I or their salts as well as potentially to methods for the treatment, amelioration or prevention of conditions that could be treated by inhibiting aldosterone synthase.
