Phosphorus nitrogen compounds: Part 34. Syntheses, structural investigations, cytotoxic and biological activities of spiro-ansa-spiro and spiro-bino-spiro tetrameric phosphazene derivatives
Berberoglu, Ipek; Asmafiliz, Nuran; Kilic, Zeynel; Hokelek, Tuncer; Koc, L. Yasemin; Acik, Leyla; Dal, Hakan (Elsevier Science Sa, 2016)The reactions of N4P4Cl8 with the symmetric N2N2 (1-3) and N2O2 (4) bulky ligands gave partly substituted 2,4-sas (5 and 6), 2,6-sas (7-10) and sbs (11-14) tetrameric phosphazene derivatives. The 2,4-sas-5, 2,6-sas-8 and ... -
Phosphorus-nitrogen compounds Part 32. Structural and thermal characterizations, antimicrobial and cytotoxic activities, and in vitro DNA binding of the phosphazenium salts
Akbas, Huseyin; Okumus, Aytug; Karadag, Ahmet; Kilic, Zeynel; Hokelek, Tuncer; Koc, L. Yasemin; Turk, Mustafa (Springer, 2016)The salicylic acid salts of fully substituted mono(4-fluorobenzyl)spirocyclotriphosphazenes (10-15) were prepared. The structures of these phosphazenium salts (10a-15a) were determined by elemental analyses, FTIR and H-1, ... -
Phosphorus-nitrogen compounds part 33: in vitro cytotoxic and antimicrobial activities, DNA interactions, syntheses, and structural investigations of new mono(4-nitrobenzyl)spirocyclotriphosphazenes
Okumus, Aytug; Akbas, Huseyin; Kilic, Zeynel; Koc, L. Yasemin; Acik, Leyla; Aydin, Betul; Dal, Hakan (Springer, 2016)The condensation reactions of hexachlorocyclotriphosphazene, N3P3Cl6, with N-alkyl-N'-mono(4-nitrobenzyl)diamines (1-3), NO2PhCH2NH(CH2) (n) NHR1 (R-1 = CH3 or C2H5), led to the formation of the mono(4-nitrobenzyl)spiroc ... -
Phosphorus-nitrogen compounds: Part 31. Syntheses, structural and stereogenic properties, in vitro cytotoxic and antimicrobial activities, and DNA interactions of bicyclotetraphosphazenes containing bulky side group
Mutlu, Gurcu; Elmas, Gamze; Kilic, Zeynel; Hokelek, Tuncer; Koc, L. Yasemin; Turk, Mustafa; Dal, Hakan (Elsevier Science Sa, 2015)Hexachlorocyclotriphosphazene, N3P3Cl6, and octachlorocyclotetraphosphazene, N4P4Cl8, were reacted with K2N2O2 salt of symmetric tetradentate ligand to obtain spiro-bino-spiro [(sbs) (2)] and 2,6-spiro-ansa-spiro [(2,6-sas) ...
