An air- and moisture-stable molybdenum Schiff base complexes immobilized on magnetic iron oxide nanoparticles with a core-shell structure was developed for utilization as a new heterogeneous catalyst. The surface, structural and magnetic characteristics of the nanomaterials were characterized by using Fourier transform infrared (FT-IR) spectroscopy, X-ray powder diffraction (XRD), vibrating sample magnetometry (VSM), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and inductively coupled plasma atomic emission spectroscopy (ICP-AES). In application point of view, an ultrasonic assisted one-pot multicomponent protocol for the synthesis of 1-(α-aminoalkyl)-2-naphthol derivatives have been demonstrated under mild condition with short reaction times, high yields and TON values up to 570. To survey the generality of the procedure, we studied the synthesis of α-aminonitrile derivatives with different aldehydes, trimethylsilyl cyanide (TMSCN) and aniline under the same conditions. Additionally, binding interaction of 1-(phenyl(pyridin-2-ylamino)methyl)naphthalen-2-ol (AMAN-1) with various types of rigid DNA and HSA has been investigated by molecular modeling study. In vitro studies under physiological conditions showed that the desired derivative interacts with calf-thymus DNA (ct-DNA) via an intercalative binding mode.
