Using an in-cell AMPK activation assay, we have developed structure-activity relationships around a hit pyridine dicarboxamide 5 that resulted in 40 (R419). A particular focus was to retain the on-target potency while also improving microsomal stability and reducing off-target activities, including hERG inhibition. We were able to show that removing a tertiary amino group from the piperazine unit of hit compound 5 improved microsomal stability while hERG inhibition was improved by modifying the substitution of the central core pyridine ring. The SAR resulted in 40, which continues to maintain on-target potency. Compound 40 was able to activate AMPK in vivo after oral administration and showed efficacy in animal models investigating activation of AMPK as a therapy for glucose control (both db/db and DIO mouse models). In the experiment, the researchers used many compounds, for example, tert-Butyl 4-(4-fluorobenzoyl)piperidine-1-carboxylate (cas: 160296-40-2Safety of tert-Butyl 4-(4-fluorobenzoyl)piperidine-1-carboxylate).
tert-Butyl 4-(4-fluorobenzoyl)piperidine-1-carboxylate (cas: 160296-40-2) belongs to piperidine derivatives. The piperidine structural motif is present in numerous natural alkaloids. These include piperine, which gives black pepper its spicy taste. The piperidine and polyhydroxylated indolizidine derivatives have shown to be promising 伪-glucosidase inhibitors. The former are analogs of DNJ with an improved 伪-glucosidase inhibitory profile than that of DNJ. Boisson et al.Safety of tert-Butyl 4-(4-fluorobenzoyl)piperidine-1-carboxylate
