Abstract:Some triphenyltin(IV) adducts with a family of diphosphoryl ligands, RR 0 P(O)-X-P(O)RR 0 (R ¼ OPh, Ph, R 0 ¼ R, An (aniline)) and X ¼ 1,4-OC 6 H 4 O, 1,4-OC 6 H 4 NH, 1,4-NHC 6 H 4 NH 1,4-(NHCH 2 ) 2 C 6 H 4 , 1,3-(NHCH 2 ) 2 C 6 H 4 and piperazine have been synthesized and characterized by IR and NMR spectroscopy. X-Ray crystallography reveals that the structure of these complexes comprises a binuclear arrangement with two SnPh 3 Cl moieties linked via the bridging P(O)-X-P(O) ligands.

Section: Synthesis Of Bisphosphoramidate Compoundsmentioning
Bisphosphoramidates are known as anticancer, antibacterial, antiviral drugs and enzyme inhibitory agents. These compounds are electroactive and insoluble in aqueous media. Hence, a comprehensive study about the electrochemical properties of them seems very interesting. The oxidative behaviors of some bisphosphoramidates were studied in buffer solution over a wide pH range by cyclic voltammetry and differential pulse voltammetry using spiked carbon paste electrodes. The interaction of these compounds with calf thymus DNA (CT‐DNA) showed the ability of these compounds as DNA sensing. The decrease in the anodic peaks of bisphosphoramidates in the presence of DNA was used for the DNA monitoring.
{L = C 6 H 5 (O)P(NHC 6 H 11 ) 2 } have been synthesized by sonochemical processes at different concentrations without any surfactant or capping agent. The structure and morphology of the prepared complex were investigated by using SEM-EDAX, XRD, DLS, UV-Vis and FT-IR spectroscopy. Nanoparticles with well-defined rod shapes and sizes in the range 30-40 nm have been obtained. Also bulk form of the titled complex was synthesized and characterized by 1 H, 13 C, 31 P, 119 Sn NMR, UV-Vis and FT-IR spectroscopy and compared with its nano-size. The thermal stabilities at bulk and nano-size scale have been studied by thermal gravimetric (TG) and differential thermal analysis (DTA). Further, SnP 2 O 7 nanoparticles were synthesized by direct calcination at 730°C under air atmosphere and characterized using XRD, SEM, and TEM. From XRD measurements, we determined the mean size of the crystallites about 27.4 nm. It is found that the size and morphology of the tin pyrophosphate nano-structures are dependent upon the particles size of precursor compound as well. Two different forms of metal coordination compound (1a, 1b) and the corresponding ligand (L) were screened for their antibacterial activity against the selected Gram-positive and Gramnegative bacteria, showing bactericidal activity for complexes 1a and 1b. In vitro cytotoxicity of compounds was studied against human carcinoma cell lines, A2780 (ovarian cancer) and PC-3 (prostate cancer). Results indicated that 1a and 1b possess relatively strong cytotoxic activity against cancer cells with IC 50 values ranging from 93.2 to 376.2 μM for two exposure time (24 and 48 h).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
