Pyrrolomycins C, D and E, new members of pyrrolomycins produced by Actinosporangium vitaminophilum SF-2080, have been isolated by chromatography on a basic alumina column. Three antibiotics have chlorinated pyrrole nuclei linked directly or via carbonyl function to the dichlorophenol moiety. Pyrrolomycins C and E are active against Gram-positive bacteria, while the spectrum of pyrrolomycin D is...

Abstract In this work, we synthesized and characterized an azo dye of amino pyridine namely 6-[3- pyridylazo]-2,4-dichlorophenol (PADCP) furthermore its complexes cobalt, nickel copper divalent ions. The infrared spectra refereed that PADCP ligand coordinates by oxygen nitrogen atoms to the metals in as bidentate ligand. have general formula [M(PADCP) 2 ] which confirmed elemental analysis, mag...
