New bispyrazoline derivatives built around aliphatic chains: Synthesis, characterization and antimicrobial studies

Synthesis and characterization of carbazole derivatives and their antimicrobial studies.

The reaction of 1-oxo-1,2,3,4-tetrahydrocarbazoles (1a-e) with paraformaldehyde and ethylenediamine yielded N,N'-bis(1,2,3,4-tetrahydrocarbazol-1-ylidene)ethane-1,2-diamines (2a-e). Here, like in another similar attempt of replacing ethylenediamine by ethanolamine, ended up in formation of 2-{[1-(2-(2-aminoethoxy)ethylimino)-1,2,3,4-tetrahydrocarbazol-2-yl-methyl]amino}ethanols (3a-e). These pr...

1,3,4-Oxadiazole Derivatives: Synthesis, Characterization, Antimicrobial Potential, and Computational Studies

We report the synthesis and biological assessment of 1,3,4-oxadiazole substituted 24 derivatives as novel, potential antibacterial agents. The structures of the newly synthesized derivatives were established by the combined practice of UV, IR, (1)H NMR, (13)C NMR, and mass spectrometry. Further these synthesized derivatives were subjected to antibacterial activity against all the selected micro...

Synthesis, Characterization and Antimicrobial Study of Some New Cyclohexenone Derivatives

synthesis and characterization of some new cyclometalated organoplatinum(ii) complexes containing phosphite ligand

در این تحقیق روشی جهت سنتز یک سری از کمپلکس های پلاتین (ii) حاوی لیگاند های دهنده ی فسفری شامل فسفیت و فسفین ارائه شده است. واکنش پیش ماده ی پلاتین (ii)،trans/cis- [ptcl2(sme2)2] ، با 2 اکی مولار از لیگاند p(oph)3در حلال بنزن کمپلکس1، cis-[ptcl2(p(oph)3)2] را تولید می نماید. جهت سنتز کمپلکس سایکلو متال فسفیتی، کمپلکس 1 با 1 اکی والان واکنشگر ptcl2 در حلال زایلن در شرایط رفلاکس زیر گاز آرگون م...

Synthesis and Antimicrobial Activity of Some New Isatin Derivatives

Some new 3-[(5-benzylidene-2-phenyl)-3, 5-dihydro-4-H-imidazol-4-one-3-(4-bezoylhydrazono)]-indole-2-ones (VIII) have been synthesized from different isatinhydrazones (II) by condensing with 2-phenyl-5-benzylidene- 3-N (4-acetyl phenyl)-1, 5-dihydro-imidazol-4-one (VII). Their chemical structures have been confirmed by IR, 1HNMR, MASS and by elemental analysis. Investigation of antimicrobial ac...
