A TBAI-catalyzed reaction between N-tosyl hydrazone and sulfur was developed, leading to 1,2,3-thiadiazoles in moderate to good yields. It represents a facile and practical procedure to access thiadiazole under metal-free conditions. This procedure serves

The base exchange of nicotinamide with pyridine derivatives 1a-5a, catalyzed by pig brain NAD+ glycohydrolase and ADP-ribosyl cyclase from Aplysia californica, generated the corresponding NAD+ analogs 1b-5b. These analogs exhibited a high absorbance band in the visible region. The transglycosidation rate was determined by monitoring the absorbance increase. Among the tested derivatives, (E)-4-[2-(methylsulfanyl)-vinyl]-pyridine 1a was the most suitable substrate for pig brain NAD+ glycohydrolase while 4-[1,3]-dithiolan-2-ylidenemethyl-pyridine 3a was the most efficient for ADP-ribosyl cyclase from A. californica.

Novel cephalosporin derivatives and salts thereof are disclosed. These compounds exhibit excellent antimicrobial activity against a wide variety of Gram-negative and Gram-positive bacteria and also have other excellent characteristics as a medicine such as stability and low toxicity. These compounds can be administered in a form of subcutaneous, intravenous or intramuscular injections.
