## Abstract

Methods and pharmaceutical compositions comprising one or more prodrugs (e.g., aminoalkyl prodrugs) of monomethyl fumarate (MMF) thereof are provided herein for the treatment of a heart failure disease, including heart failure with preserved ejection fraction. The compounds of the present disclosure are configured to be converted in vivo, upon oral administration, to monomethyl fumarate. Upon conversion, the active moiety (i.e., monomethyl fumarate) of various embodiments is effective in treating subjects suffering from a heart failure disease, including heart failure with preserved ejection fraction.
