Studies on Anti-MRSA Parenteral Cephalosporins. II. Synthesis and Antibacterial Activity of 7.BETA.-[2-(5-Amino-1,2,4-thiadiazol-3-yl)-2(Z)-alkoxyiminoacetamido]-3-(substituted imidazo [1,2-b]pyridazinium-1-yl)methyl-3-cephem-4-carboxylates and Related Compounds.
Chronic hepatitis B viral infection is a significant health problem world-wide, and currently available antiviral agents suppress HBV infections, but rarely cure this disease. It is presumed that antiviral agents that target the viral nuclear reservoir of transcriptionally active cccDNA may eliminate HBV infection. Through a series of chemical optimization, we identified a new series of glyoxamide

A method for the one-pot synthesis of phenothiazines from benzothiazoles and aryl ortho-dihalides was explored. Preliminary work on the mechanism of the reaction suggested that it follows a domino process, including the hydrolysis of benzothiazoles followed by C–S coupling and C–N coupling. The low loading of the catalyst system (5 mol-% for both copper and ligand), the mild experimental conditions
