Analogues of clinical tuberculosis drug (6S)-2-nitro-6-{[4-(trifluoromethoxy)benzyl]oxy}-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazine (PA-824), in which the OCH(2) linkage was replaced with amide, carbamate, and urea functionality, were investigated as an alternative approach to address oxidative metabolism, reduce lipophilicity, and improve aqueous solubility. Several soluble monoaryl examples

A series of N-substituted 9-azabicyclo[3.3.1]nonan-3alpha-yl phenylcarbamate analogs were synthesized. Among them, WC-26 and WC-59 were identified as the most potent sigma(2) receptor ligands (K(i)=2.58 and 0.82 nM, respectively) with high selectivity against sigma(1) (K(i) of sigma(1)/sigma(2) ratio=557 and 2087, respectively).

Amorphous poly(ethylene ether carbonate) (PEEC), which is a copolymer of ethylene oxide and ethylene carbonate, was synthesized by ring-opening polymerization of ethylene carbonate. This route overcame the common issue of low conductivity of poly(ethylene oxide)(PEO)-based solid polymer electrolytes at low
