- Synthesis and biological evaluation of all eight stereoisomers of DPP-IV inhibitor saxagliptin
-
All eight stereoisomers of saxagliptin have been synthesized and evaluated for their inhibitory activity against DPP-IV. It was unambiguously confirmed that the configuration of saxagliptin was critical to potent inhibition of DPP-IV. Docking study was performed to elucidate the configuration-activity relationship of saxagliptin stereoisomers. Tyr662 and Tyr470 have been suggested as the key residues of DPP-IV interacting with the inhibitors. This work provides valuable information for further inhibitor design against DPP-IV.

- CYCLIC AMINE DERIVATIVES AS EP4 RECEPTOR ANTAGONISTS
-
There is described a novel group of cyclic amine derivative compounds, having an EP4 receptor antagonistic activity and specifically pharmaceutical compounds which are useful for the treatment or alleviation of Prostaglandin E mediated diseases. The present invention therefore relates to novel compounds which are selective antagonists of the EP 4 sub type of PGE2 receptors with analgesic and antinflammatory activity, processes for their preparation, pharmaceutical compositions containing them and theiruse as medicaments, inter alia for the treatment or alleviation of Prostaglandin E mediated diseases such as acute and chronic pain, osteoarthritis, inflammation-associated disorder as arthritis, rheumatoid arthritis, cancer, migraine and endometriosis.
