New quinoxaline compounds as DPP-4 inhibitors and hypoglycemics: Design, synthesis, computational and bio-distribution studies

The current work represents the design and synthetic approaches of a new set of compounds 6-10 bearing the 1,4-dimethyl-2,3-dioxo-1,2,3,4-tetrahydroquinoxaline-6-sulfonamide scaffold. The biological evaluation revealed that most of the new compounds were promising selective dipeptidyl peptidase-IV (DPP-4) inhibitors and in vivo hypoglycemic agents utilizing linagliptin as a standard drug. The acute toxicity examination confirmed the safety profile of all compounds. Molecular docking studies related the significant DPP-4 suppression activity of compounds 9a, 10a, 10f, 10g to their nice fitting in the active pocket of DPP-4. In addition, the molecular dynamic study exhibited the stability of both 10a and 10g within the active site of DPP-4. The QSAR study showed that the difference between the predicted activities is very close to the experimental suppression effect. Moreover, both compounds 10a and 10g obeyed Lipinski's rule, indicating their efficient oral bioavailability. Compound 10a was radiolabeled, forming the 131I-SQ compound 10a to study the pharmacokinetic profile of this set of compounds. The biodistribution pattern hit the target protein since the tracer accumulated mainly in the visceral organs where DPP-4 is secreted in a high-level, thus with consequent stimulation of insulin secretion, leading to the target hypoglycemic effect.

Identification of human T2R receptors that respond to bitter compounds that elicit the bitter taste in compositions, and the use thereof in assays to identify compounds that inhibit (block) bitter taste in composition and use thereof

The present invention relates to the discovery that specific human taste receptors in the T2R taste receptor family respond to particular bitter compounds present in, e.g., coffee. Also, the invention relates to the discovery of specific compounds and compositions containing that function as bitter taste blockers and the use thereof as bitter taste blockers or flavor modulators in, e.g., coffee and coffee flavored foods, beverages and medicaments. Also, the present invention relates to the discovery of a compound that antagonizes numerous different human T2Rs and the use thereof in assays and as a bitter taste blocker in compositions for ingestion by humans and animals.
