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 100娓璏. 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 experiment, the researchers used many compounds, for example, Methyl 4-fluoro-3-methylbenzoate (cas: 180636-50-4HPLC of Formula: 180636-50-4).
Methyl 4-fluoro-3-methylbenzoate (cas: 180636-50-4) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esters contain a carbonyl center, which gives rise to 120鎺?C閳ユ弲閳ユ彊 and O閳ユ弲閳ユ彊 angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C閳ユ彊閳ユ弲 bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
