Abstract

In one aspect, the invention relates to a crystalline form of the structure: or a pharmaceutically acceptable salt thereof, having neprilysin inhibition activity. In another aspect, the invention relates to pharmaceutical compositions comprising this crystalline form; methods of using this crystalline form and its soluble form (I); and processes for preparing soluble (I) and crystalline (I′) forms.
