MexAB-OprM specific efflux pump inhibitors in Pseudomonas aeruginosa. Part 5: Carbon-substituted analogues at the C-2 position
摘要:
A series of 4-oxo-4-1-pyrido[1,2-a]pyimidine derivatives, derivatized at the 2-position with carbon-linked substituents, were synthesized and evaluated for their ability to potentiate the activity of the fluoroquinolone levofloxacin (LVFX) and the anti-pseudomonas beta-lactam aztreonarn (AZT) in Pseudomonas aeruginosa. Palladium-catalyzed cross-coupling methods were applied for the incorporation of aliphatic and aromatic substituents. (c) 2005 Elsevier Ltd. All rights reserved.

converted into the alkylated arenes and ketone products, respectively. The utility of this newly developed protocol was demonstrated by its wide substrate scope, broad functional group tolerance and application in the synthesis of keyintermediates for the synthesis of bioactive compounds. DFT studies on the oxidative addition step helped rationalizing this intriguing reaction chemoselectivity: whereas

We herein outline the design of a new series of agonists of the pancreatic and GI-expressed orphan G-protein coupled receptor GPR119, a target that has been of significant recent interest in the field of metabolism, starting from our prototypical agonist AR231453. A number of key parameters were improved first by incorporation of a pyrazolopyrimidine core to create a new structural series and secondly
