Abstract
New spiro[indoline-3,4'-[1,3]dithiine]@Cu(NO3)2 supported on Fe3O4@gly@CE magnetic nanoparticle were synthesized and used as efficient and recyclable catalyst in the synthesis of 2-oxospiro[indoline-3,4'-[1,3]dithiine]-5'-carbonitrile derivatives. The structure of magnetic nanoparticles were confirmed using energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM), thermogravimetric analysis (TGA), infrared spectroscopy (FT-IR) and inductively coupled plasma optical emission spectroscopy (ICP-OES). Subsequently, antibacterial and antifungal activities in terms of inhibition zone diameter, minimum inhibitory concentration, minimum bactericidal concentration and antioxidant activity against the DPPH free radical of the derivatives were investigated. The results revealed acceptable biological effects of the synthetic derivatives and a significant relationship between their structure and biological activity were observed.
