An imine-based 2D polymer side-functionalized with o-hydroxyl group was designed in regard to its potential ability to serve as a chelating agent and synthesized on a highly oriented pyrolytic graphite surface with a relatively low annealing temperature. When annealed to a higher temperature the o-hydroxyl group reacts further with the imine group, leading to the formation of oxazoline, which c...

Sir: Kanamycins are inactivated by enzymes of resistant bacteria phosphorylating or adenylylating the 3', 4' or 2"-hydroxyl groups' 21 , among which the 3'-hydroxyl group is most frequently modified. Syntheses of 3'-deoxykanamycin A3), 3',4'-dide-oxykanamycin B4) (dibekacine), and other deoxy derivatives of kanamycins and related aminogly-coside antibiotics were the major solution"" in order to...

This article reports the synthesis and characterization of a new binuclear complex of palladium (II) containing the antibiotic oxytetracycline. The complex was characterized by the usual techniques of analysis. With respect to sites of coordination, the IR spectral data suggests the involvement the oxygen of the amide group and the oxygen of the neighbor hydroxyl group at ring A and to the carb...
