The present invention relates to compounds of formula (I), which have valuable pharmacological properties, in particular are activators of AMPK and which are therefore useful in the treatment of certain disorders that can be prevented or treated by activation of this receptor. The compounds are suitable for treatment and prevention of diseases which can be influenced by this receptor, such as metabolic diseases, in particular diabetes type 2.
This disclosure is directed, at least in part, to AMPK activators useful for the treatment of conditions or disorders associated with AMPK. In some embodiments, the condition or disorder is associated with the gut-brain axis. In some embodiments, condition or disorder is associated with systemic infection and inflammation from having a leaky gut barrier. In some embodiments, the AMPK activators are gut-restricted compounds. In some embodiments, the AMPK activators are agonists or partial agonists.
