- Synthesis, characterization and antimicrobial evaluation of new 3-(Alkyl/Arylamino)benzo[d]isothiazole 1,1-derivatives
-
The saccharine nucleus has long been recognized as a significant component in medicine. A series of pseudo-saccharine amines derivatives (7a-j) were synthesized and examined for their antibacterial activity. After testing all compounds, 7b, 7f, 7g, 7i and 7j were found most effective against Escherichia coli, Streptococcus aureus and Bacillus subtilis strains. The MIC of the compound was found from 4.6 to 16.1 μM. Further, compound 7f and 7i exhibited excellent activity against E.coli and Bacillus subtilis with MIC value 4.6 and 4.7 μM respectively. The compound 7b and 7i was found active against all the three bacteria. The zone inhibition was observed at 10 μM against Escherichia coli, Staphylococcus aureus and Bacillus subtilis at 0.9, 1.8, 3.9 respectively for 7b and 1.0, 1.8 and 2.0 cm respectively for 7i.

- Metal-assisted reactions. Part 29. Structure and hydrogenolysis of C-N bonds in derivatives of aromatic amines. Bond length and electronegativity changes from X-ray crystallographic data
-
Pseudosaccharyl and phenyltetrazolyl derivatives 1-6 were prepared with the aim of weakening the originally strong C-N bond in aromatic amines and facilitating its hydrogenolysis. Structural analyses of the amines 1-6 by 1H and 13C NMR spectroscopy and X-ray diffraction methods have revealed major changes in C-N bond lengths on derivatization as a result of changes in conjugation. These changes are discussed in relation to the observed reactivity of compounds 1-6 towards catalytic and non-catalytic C-N bond hydrogenolysis.
