Ag2Cr2O7 nanoparticles were found to be an exceedingly effective catalyst for the mild and green synthesis of aminobenzochromenes. The reaction was performed under ultrasonic irradiation as an innocuous tool and in water a

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.

Silver (I) salicylate complex marked as [Ag(HSal)] was prepared, characterized, and applied to fabricate AgSCN micro/nanostructures. The [Ag(HSal)] complex was synthesized by silver nitrate and sodium salicylate via a simple precipitation route. To obtain AgSCN micro/nanostructures, the [Ag(HSal)] complex and KSCN were mixed with molar ratio of 1:1 in the presence of ultrasound irradiation. Besides, the effect of sonication time and surfactant on the morphology and particle size of the products was investigated. In this work, polyvinyl pyrrolidone was used as surfactant to prepare star-like and flower-like AgSCN microstructures. The products were analyzed by FT-IR, XRD, EDS, SEM, and TEM.
