Anti-tumor Activity of N4 [(E)-1-(2-hydroxyphenyl) Methylidene], N4-[(E)-2-Phenylethylidene], N4 [(E,2E)-3-Phenyl-2-propenylidene], and N4[(E)ethylidene] Isonicotinohydrazide on K562 and Jurkat Cell Lines

Anti-tumor Activity of N4 [(E)-1-(2-hydroxyphenyl) Methylidene], N4-[(E)-2-Phenylethylidene], N4 [(E,2E)-3-Phenyl-2-propenylidene], and N4 [(E)ethylidene] Isonicotinohydrazide on K562 and Jurkat Cell Lines

Using the water eliminated mechanism, reactions of 4-pyridinecarboxylic acid hydrazide and salicylaldehyde, benzaldehyde, cinnamaldehyde, and formaldehyde afforded the corresponding N(4)[(E)-1-(2-hydroxyphenyl) methylidene] (NHPM), N(4)-[(E)-2-phenylethylidene] (NPI), N(4)[(E,2E)-3-phenyl-2-propenylidene] (NPPI), and N(4)[(E) ethylidene] (NEI) isonicotinohydrazide, in high yields, after several...

Bis(mu-phenyl 2-pyridyl ketone N4,N4-butane-1,4-diylthiosemicarbazonato)bis[chlorocopper(II)].

The title compound, [Cu2(C17H17N4S)2Cl2], exhibits a dimeric structure related by a centre of symmetry. The monomers are linked to each other by the longest Cu-S apical distance observed to date among Cu(II) square-pyramidal complexes of N4-substituted thiosemicarbazones. Each Cu(II) atom deviates from the coordination square plane, which contains the pyridyl and imine N atoms, the thiolate S a...

Selective antimicrotubule activity of N1-phenyl-3,5-dinitro-N4,N4-di-n-propylsulfanilamide (GB-II-5) against kinetoplastid parasites.

Analogs of the antimitotic herbicide oryzalin (3,5-dinitro-N4,N4-di-n-propylsulfanilamide) were recently prepared that were more potent in vitro than the parent compound against the kinetoplastid parasite Leishmania donovani (Bioorg Med Chem Lett 12:2395-2398, 2002). In the present work, we show that the most active molecule in the group, N1-phenyl-3,5-dinitro-N4,N4-di-n-propylsulfanilamide (GB...

Synthesis and Antimicrobial Activity of Some 2-[(4-Substituted-Phenyl-3-Chloro-Azetidin-2-One)-5-(2'-Methylamino-4-Phenyl-1', 3'-Thiazolyl-]-1, 3,4-Thiadiazoles

A new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. The synthesised compounds have been screened in vitro for their antimicrobial acti...
