Abstract
A new series of benzothiazolo-benzothiadiazine hybrids (9a-g) has been synthesized and evaluated for their antibacterial activity against clinical isolates of Gram-positive and Gram-negative bacteria. Some of these hybrids in this series exhibited antibacterial activity comparable to ampicillin. In addition, some of the compounds showed DNA gyrase inhibitory activity at a moderate level compared to ciprofloxacin.
