Background: Doxorubicin, as a strong anti-cancer agent for clinical treatment of various cancer types along with other drugs, is widely utilized. Due to the physiology of the human body and cancerous tissues, the applicability of doxorubicin is still limited and the targeted treatment of the different types of cancers is considered. Also, the side effects of the conventional forms of chemotherapy medicines, damaging and stressing the normal cells are considerable. Objective: This study introduces a novel and effective system for the targeted release of doxorubicin by successfully fabricating the green magnetic graphene oxide, chitosan, allium sativum, and quercus nanocomposite. Methods: The in vitro release of doxorubicin loaded on the nanocomposite was evaluated and investigated at pH 7.4 and 6.5, respectively. The drug diffusivity in the plasma environment was assessed for a more accurate analysis of the drug diffusion process. The nanocomposite loaded drug release mechanism and kinetics, as well as cytotoxicity assay was investigated. Results: The efficiency of the drug encapsulation was significantly enhanced using natural extract ingredients and consequently, the efficacy of the targeted treatment of cancerous tissues was improved. The developed nanocomposite provided a controlled release of doxorubicin in similar acidic conditions of the normal and cancerous cells and affirming that the fabricated system is thoroughly pH-dependent. Conclusion: The cytotoxicity assay confirmed that the fabricated nanocomposite at a high growth rate of cancerous cells has an anticancer property and acts as a toxic agent against tumor cells, suggesting that in conjunction with doxorubicin, it can be highly improved for killing cancerous cells.

Chemotherapy is a major therapeutic approach for the treatment of localized and metastasized cancers. Although Doxorubicin (DOX) possesses abroad spectrum of anticancer activity, its clinical use is limited because of it cause heart failure. Chitosan nanoparticles was prepared by using ionic gelation method. These nanoaparticles were used as polyload of anticancer DOX to form safer and non-toxic anticancer drug. infrared spectroscopy (FTIR) and transmission electron microscope (TEM) were used to characterize the prepared nanoparticles. The cancer animals’ experiments using Ehrlich static cancer, (EAC) cells using six groups of experimental animals were performed to evaluate the efficiency of Doxorubicin and Doxorubicin loaded chitosan nanoparticles as anticancer drug especially from its toxicity towards heart. Tumor volume was calculated as to monitor the response to treatment. Cytotoxicity of Doxorubicin and Doxorubicin loaded chitosan nanoparticles were evaluated. Biochemical parameters were be estimated to illustrate the cytotoxicity of these drugs on heart.

195Pt and 15N n.m.r, spectra for aqueous solutions of the anti-cancer drug cis-diamminedichloroplatinum(II) and its hydrolysis and oligomerization products are reported. In the blood substituteHanks medium, conversion of cis-[Pt(15NH3)2(H20)2](NO3)2 into cis[PtCl2(15NH3)2], cis-[PtCl(H20)(15NH3)2]+,[Pt(15NH3)2OH]33+ and [Pt(15NH3)2OH]22+ has been observed, the reaction taking several hours at 30�C. In 0.15 M sodium chloride, both [Pt(NH3)2OH]33+ and[Pt(NH3)2OH]22+ are converted overnight into cis-[PtCl(H2O)(NH3)2]+. The infrared bands at 546 and 522 cm-1 in [Pt(NH3)2OH]2SO4 and at 520 cm-1 in [Pt(NH3)2OH]2(SO4)3 have been reassigned to Pt-N modes.
