Fluoroquinolones are one of the most promising and vigorously pursued areas of contemporary antiinfective chemotherapy depicting broad spectrum and potent activity. They have a relatively simple molecular nucleus, which is amenable to many structural modifications. These agents have several favorable properties such as excellent bioavailability, good tissue penetrability and a relatively low in...

In 200 sulfonamide-resistant Portuguese Salmonella isolates, 152 sul1, 74 sul2, and 14 sul3 genes were detected. Class 1 integrons were always associated with sul genes, including sul3 alone in some isolates. The sul3 gene has been identified in isolates from different sources and serotypes, which also carried a class 1 integron with aadA and dfrA gene cassettes.

In the title compound, C(6)H(6)Cl(2)N(2)O(2)S, the O atoms of the sulfonamide group lie on one side of the benzene ring and the amino group lies on the opposite side. An inter-molecular N-H⋯Cl inter-action occurs. In the crystal, adjacent mol-ecules are linked by N-H⋯O hydrogen bonds, forming a three-dimensional structure with supporting π-π stacking inter-actions [centroid-centroid distance = ...
