Substituted phenyl, naphthyl, and thienyl N-hydroxy urea compounds form a class of potent inhibitors of 5- and 12-lipoxygenase and are thus useful compounds in the treatment of inflammatory disease states where leukotrienes and other products of lipoxygenase enzyme activity are implicated.
Synthesis and antibacterial activity of N-[2-[5-(methylthio)thiophen-2-yl]-2-oxoethyl] and N-[2-[5-(methylthio)thiophen-2-yl]-2-(oxyimino)ethyl]piperazinylquinolone derivatives
piperazinylquinolone derivatives were synthesized and evaluated for antibacterialactivity against Gram-positive and Gram-negative bacteria. Preliminary results indicated that most compounds tested in this study demonstrated comparable or better activity against Staphylococcus aureus and Staphylococcus epidermidis than their parent piperazinylquinolones as reference drugs. Among these derivatives, ciprofloxacin

An effective approach for the direct thiolation of five-membered heteroarenes involving visible-light-absorbing EDA complexes is reported. The reaction takes place from an EDA complex between an alkylamine and the heteroarene halide. Selective photolysis to the EDA complex has allowed to generate the heteroarene radical that is suitably trapped by disulfide derivatives, providing a potent synthetic
