dc.description.abstractThe purpose of this study is to synthesize the new branched magnetic nanocomposite to carry the therapeutic agents and bio-macromolecules. Although topotecan (TPT) has significant antitumor activity to lung, ovarian, breast, pancreas, and stomach cancers, lactone ring opening causes a reduction in cytotoxic activity and severe side effects in physiological conditions. In order to contribute to the removal of the handicap (lactone ring opening), magnetic dextran branched with NαNα-Bis (carboxymethyl)-l-lysine hydrate (NTA) nanoparticles (MD3) were prepared. The characterization of the resulting MD3 material was done by using multi-pronged analyses. The stability and release of TPT with synthesized and characterized new material of the MD3 was studied using various essential factors like concentration, dosage, pH, and time. The entrapment efficiency and loading capacity of TPT onto MD3 was calculated as 32.2% and 1.44 mg/g, respectively, at pH 5. Release studies were performed with drug-loaded MD3 at different pH values. It was seen that the best release was obtained at the cancerous site pH. Initial drug concentration was measured as 0.118 mM. The loaded drug concentration was calculated as 0.0380 mM at pH 5 and 0.00092 mM of drug was released after 90 min at pH 5.8. Percentage released of drug was found as 2.42% during 90 min. [Figure not available: see fulltext.].en_US
