(Chemical Equation Presented) A practical large-scale chromatography-free synthesis of EP4 antagonist MF-310, a potential new treatment for chronic inflammation, is presented. The synthetic route provided MF-310 as its sodium salt in 10 steps and 17% overall yield from commercially available pyridine dicarboxylate 7. The key features of this sequence include a unique regioselective reduction of succinimide 2 controlled by the electronic properties of a remote pyridine ring, preparation of cyclopropane carboxylic acid 3 via a Corey - Chaykovsky cyclopropanation, and a short synthesis of sulfonamide 5. 2009 American Chemical Society.

-
, (2008/06/13)
The invention is directed to quinoline derivatives as prostaglandin E type receptor antagonists useful for the treatment of EP4 mediated diseases or conditions, such as acute and chronic pain, osteoarthritis, rheumatoid arthritis and cancer. The derivatives have the following structure of formula (I): wherein A and B represents either a nitrogen atom or a CH group with the proviso that they cannot both simultaneously be CH, Q can represent a nitrogen or a carbon atom, and Y and Z are either a nitrogen atom., a N(O) group or a C(R5) group. Pharmaceutical compositions comprising the derivatives of formula (I) are also included.
