For the first time, silver salicylate marked as [Ag(HSal)] was applied to fabricate silver selenide nanoparticles. This article describes a simple approach based on reaction between silver salicylate as an inorganic precursor, SeCl4, and hydrazine hydrate (N2H4.H 2O) via sonochemical route for the fabrication of silver selenide (Ag2Se) nanoparticles. The effect of preparation parameters such as pH, ultrasonic power, and reaction temperature on the morphology of the final products was investigated. Ag2Se nanoparticles were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and X-ray energy dispersive spectroscopy (EDS).

The already known Ag(I)-Sb(III) compound of the formula {Ag(Ph3Sb)3(NO3)} (1) and two novel mixed metal Ag(I)-Sb(III) metallotherapeutics of the formulae {Ag(Ph3Sb)3(SalH)}(2) and {Ag(Ph3Sb)3(Asp)}(3) (SalH2 = salicylic acid, AspH = aspirin or 2-acetylsalicylic acid and Ph3Sb = triphenyl antimony(III)) have been synthesised and characterised by m.p., vibrational spectroscopy (mid-FT-IR), 13C-,1H-NMR, UV-visible (UV-vis) spectroscopic techniques, high resolution mass spectroscopy (HRMS) and X-ray crystallography. Compounds 1,- 3 were treated with the surfactant cetyltrimethylammonium bromide (CTAB) in order to enhance their solubility and as a consequence their bioactivity. The resulting micelles a-c were characterised with X-ray powder diffraction (XRPD) analysis, X-ray fluorescence (XRF) spectroscopy, Energy-dispersive X-ray spectroscopy (EDX), conductivity, Thermal gravimetry-differential thermal analysis (TG-DTA), and atomic absorption. Compounds 1-3 and the relevant micelles a-c were evaluated for their in vitro cytotoxic activity against human cancer cell lines: MCF-7 (breast, estrogen receptor (ER) positive), MDA-MB-231 (breast, ER negative) and MRC-5 (normal human fetal lung fibroblast cells) with sulforhodamine B (SRB) colorimetric assay. The results show significant increase in the activity of micelles compared to that of the initial compounds. Moreover, micelles exhibited lower activity against normal cells than tumor cells. The binding affinity of a-c towards the calf thymus (CT)-DNA, lipoxygenase (LOX) and glutathione (GSH) was studied by the fluorescent emission light and UV-vis spectroscopy.
