Our recently successful identification of benzoic acid-based DPP-4 inhibitors spurs the further quest for in-depth structure-activity relationships (SAR) study in S2′ site DPP-4. Thus novel benzamide fragments were designed to target the S2′ site to compromise lipophilicity and improve oral activity. Exploring SAR by introduction of a variety of amide and halogen on benzene ring led to identification of several compounds, exerting moderated to excellent DPP-4 activities, in which 4′-chlorine substituted Me amide, (R)-3-((4-(3-aminopiperidin-1-yl)-3-(but-2-yn-1-yl)-2,6-dioxo-3,6-dihydropyrimidin-1(2H)-yl)methyl)-4-chloro-N-methylbenzamide hydro chloride (17g), [2380226-71-9], showed most potent DPP-4 activity with the IC50 value of 1.6 nM. Its activity was superior to reference alogliptin. Docking study ideally verified and interpreted the obtained SAR of designed compounds As a continuation, DPP-8/9 assays revealed the designed compounds exhibited good selectivity over DPP-8 and DPP-9. Subsequent cell-based test indicated (17g) displayed low toxicity toward the LO2 cell line up to 100μM. In vivo evaluation showed (17g) robustly improved the glucose tolerance in normal mice. Importantly, (17g) exhibited reasonable pharmacokinetic (PK) profiles for oral delivery. Overall, (17g) has the potential to a safe and efficacious DPP-4 inhibitor for T2DM treatment. In the experimental materials used by the author, we found Methyl 3-(bromomethyl)benzoate(cas: 1129-28-8SDS of cas: 1129-28-8)
Methyl 3-(bromomethyl)benzoate(cas: 1129-28-8) belongs to organobromine compounds.Depending on the type of carbon to which the bromine is bonded, organic bromide could be alkyl, alkenyl, alkynyl, or aryl. Dehydrobromination, Grignard reactions, reductive coupling, Wittig reaction, and several nucleophilic substitution reactions are some of the principal reactions which involve organic bromides.
