Abstract:

Cisplatin (cis-Diaminedichloroplatinum) is one of the most effective chemotherapeutic because of its anti-neoplastic properties against various types of tumor. However, it has a wide variety of side effects such as hepato, gastrointestinal, neuro, nephro, and cardiotoxicity (acute and/or chronic) that highly restricted its usage. Thus, research work was planned to detect the role of gold (AuNPs), silver nanoparticles (AgNPs) and their corepshell (Ag@AuNPs) as a carrier for blackberry extract and to enhance its benifit in treatment of cisplatin-induced cardiotoxicity. In our work, solid-state process was used in order to prepare these nanoparticles using pectin as an ecologically friendly-polymer acting as reductant for ions and at the same time as stabilizing agent for the produced nanoparticles. This nominated method for large-scale preparation of nanoparticles is simple, efficient, and convenient. The presence of individual metallic Ag, Au and both has been proven by UV-vis spectroscopy. Transmission electron microscopy (TEM) and particle size analyzer confirmed the preparation of spherical small size with a main diameter<40 nm. The data obtained from zeta potential evaluation displayed the well stabilization for the produced nanoparticles. Transmission electron microscopy (TEM), scanning electron microscopy (SEM) and particle size analyzer have verified that the spherical small size is<40 nm in diameter. Data from zeta potential assessment revealed the good stability of the produced nanoparticles. To this end, fifty sex rats were used in this study and divided into control, cisplatin (cispt), and five treated groups. After the experimental period, lipid profile was estimated and atherogenic coefficient (AC), atherogenic index (AI), and cardiac risk ratio (CRR) were calculated. Oxidant and antioxidant parameters were also estimated. Cardiovascular disease markers were estimated by ELISA. The mean levels of cholesterol, triglycerides, malondialdehyde (MDA), advanced oxidative protein products (AOPP), and cardiovascular markers were significantly increased in cispt group compared to control; whereas these parameters were attenuated in all treated groups in particular that received blackberry (bb) loaded Ag@AuNPs. Based on these results, it can be concluded that bb has antioxidant and antilipidemic effect that help in protecting against cardiovascular disease specially when loaded with Ag@AuNPs.
