Synthesis of 2-Carbamoyl-4-Oxo-1,5-Diazabicyclo [3.2.1] Octane Derivatives as a Possible Inhibitors of Serine β-LactamasesWang, Haiyu, Shilabin, Abbas 05 April 2018 (has links)
Antibiotic resistance is becoming ever more severe due in part to the increasing use of antibiotic drugs. One significant contributor to this problem is the production of β-lactamase enzymes that provide resistance to common β-lactam antibiotics. The scope of this research is to synthesize and study the β-lactamase inhibitors of 2-carbamoyl-4-oxo-1,5-diazabicyclo [3.2.1] octane derivatives. Currently the research process is in the beginning stages of synthesizing three compounds: (R)-hexahydro-6-oxopyrimidine-4-carboxylic acid (1a), hexahydro-2,2-dimethyl-6-oxopyrimidine-4-carboxylic acid (1b) and hexahydro-6-oxo-2-phenylpyrimidine-4-carboxylic acid (1c). The future steps are to synthesize (R) -3-(methoxycarbonyl)-hexahydro-6-oxopyrimidine-4-carboxylic acid (2a), (R)-dimethyl tetrahydro-4-oxopyrimidine-1,6(2H)-dicarboxylate (3a) and (R)-methyl hexahydro-6-oxopyrimidine-4-carboxylate (4a). All the compounds will be evaluated for the inhibitory activities against pure TEM-1 and P99 β-lactamase.
