Synthesis And Characterization

This study is concerned with the synthesis and characterization of 4-thiazolidinone derivatives (3a-3e). These compounds were prepared by reacting mercaptoacetic acid with the appropriate Schiff bases (imines) by heating at 50-60 °C in chloroform with moderate yields (51- 75 %). The structures of these 4-thiazolidinone derivatives were established on the basis of spectral studies using IR, 1H-NMR, 13C-NMR, and13C-NMR DEPT .

AbstractA series of new ruthenium(II) complexes were synthesized with Schiff bases derived from salicylaldehyde / o-hydroxyacetophenone/ o-vanillin / 2-hydroxy-1-naphthaldehyde with thiosemicarbazide and acetyl furan. They are characterized by elemental analysis, IR, electronic, 1H NMR, 13C NMR and mass spectral studies. The elemental analysis suggests the stoichiometry to be 1:1 (metal:ligand). Four of these complexes were tested for its binding with CT-DNA using absorption spectroscopic studies and two of these complexes exhibit efficient DNA cleavage activity.

The reaction of the polymeric carbonyl complex [RuCl2(CO)2]x with 2-monosubstituted and 1,2-disubstituted benzimidazoles and 1,4-bis(benzimidazol- 2-yl)benzene (L9) in 2-methoxyethanol produces various coloured complexes of the formulae [Ru(CO)2Cl2(L)2]?xH2O (L = 1-(o-hydroxybenzyl)-2-(o-hydroxyphenyl)benzimidazole (L1), 1-(o-hydroxyphenyl)benzimidazole (L4), 1-(p-hydroxyphenyl)benzimidazole (L5), 1-(p-chlorobenzyl)-2-p-chlorophenyl) benzimidazole (L7), 1-[1-(dimethylamino)benzyl]-2-[1-(dimethylamino) phenyl]benzimidazole (L10), x = 0; L = 2-benzylbenzimidazole (L8), 1,4-bis(benzimidazol-2-yl)benzene (L9), x = 2; L = 1-(o-chlorobenzyl)-1-(o-chlorophenyl)benzimidazole (L6); x = 3), [Ru(CO)2Cl(L2)3]Cl?3H2O and [Ru(CO)2(L3)4]Cl2?3H2O (L2 = 1-(m-hydroxybenzyl)-2-(m-hydroxyphenyl)- benzimidazole; L3 = 1-(p-hydroxybenzyl)-2-(p-hydroxyphenyl)benzimidazole). The complexes were characterized by elemental analysis, conductivity measurements, as well as infrared, electronic, 1H- and 13C-NMR spectral studies.

A series of carbazole-based 1,4-benzothiazepine and pyrazoline derivatives were synthesized and the structures of the newly synthesized compounds were confirmed by FT-IR, 1H NMR, 13C NMR and mass spectral studies. All new derivatives 4(a-f) and 5(a-e) were screened for their in vitro antimicrobial activity, and also for their antimalarial activity. Compounds 4a, 4b, 4d, 5a, 5b and 5c exhibited promising antimicrobial and antimalarial activities as compared to positive control. Notably, compounds 4a, 4b and 4d showed excellent antifungal activity against Penicillium sp. comparable to that of a standard drug.
