Synthesis, properties, antitumor and antibacterial activity of new Pt(II) and Pd(II) complexes with 2,2′-dithiobis(benzothiazole) ligand
2017
Mono- and binuclear Pt(II) and Pd(II) complexes with 2,20-dithiobis(benzothiazole) (DTBTA) ligand are reported. [Pt(DTBTA)(DMSO)Cl]Cl∙CHCl3 (1) and [Pd2(m-Cl)2(DTBTA)2]Cl2 (2) have been synthesized and structurally characterized by elemental analysis, IR, 1H and 13C NMR spectroscopy, MS spectrometry and the content of platinum and palladium was determined using a flame atomic spectrometer. Two different coordination modes of 1 and 2 complexes were found; in both complexes, the coordination of Pt(II) and Pd(II) ions involves the N(3) atoms of the ligand but the binuclear complex 2, is a cis-chloro-bridged palladium complex. Evaluation of their in vitro antitumor activity against two human tu…
Development and characterization of co-loaded curcumin/triazole-halloysite systems and evaluation of their potential anticancer activity.
2014
Abstract Positively charged halloysite nanotubes functionalized with triazolium salts (f-HNT) were employed as a carrier for curcumin molecules delivery. The synthesis of these f-HNT new materials is described. Their interaction with curcumin was evaluated by means dynamic light scattering (DLS) and UV–vis spectroscopy in comparison with pristine unmodified HNT (p-HNT). The curcumin load into HNT was estimated by thermogravimetric analysis (TGA) measurements, while the morphology was investigated by scanning electron microscopy (SEM) techniques. Release of curcumin from f-HNT, at three different pH values, by means of UV–vis spectroscopy was also studied. Furthermore, different cancer cell …
SYNTHESIS AND CHARACTERIZATION OF POSITIVELY CHARGED FUNCTIONALIZED HALLOYSITE/CURCUMIN SYSTEMS AND EVALUATION OF THEIR ANTICANCER ACTIVITY
2014
Phenolic compound originated from one of the main class of secondary metabolites, as curcumin and its derivatives have been studied and their biological and pharmacological activities have been evaluated, too [1,2]. Unfortunately, curcumin exhibits poor bioavailability after oral or topic administration [3]. Therefore a carefully designed carrier could significantly facilitate curcumin delivery and broaden the range of its possible pharmaceutical applications. Halloysite was found to be a viable and inexpensive nanoscale container for the encapsulation of biological active molecules [4]. In this communication we report data about a new potential curcumin carrier based on positively charged …
