Interaction of doxorubicin hydrochloride in the presence of, mixed aggregate of ibuprofen sodium and cationic lipid

This research was highlighted the importance of mixed aggregates based on drug-lipid to improve the interaction of one or more drugs in aqueous medium. This mixed aggregate can significantly inhibit the growth of MCF-7 cells, and has great potential for anti-inflammatory and cancer treatment after tumor removal. The cationic lipid (CL) has been synthesized with multistep reaction and is characterized by H-1 NMR and mass spectroscopy. CL and ibuprofen (IBF) physiochemical analysis was investigated using surface tension, conductance, dynamic light scattering (DLS), and electron microscope transmission (TEM). The strong synergism between mixed aggregate (UB) system CL and IBF was observed. The study on UV spectroscopy measured that the LIB mixed aggregate showed optimum binding to doxorubicin hydrochloride (DOX) and the binding constant Log K-b was 6.17 compared to single CL, the Log K-b was 5.83. Binding results indicated that the DOX was more encapsulated in mixed LIB aggregates compared to single CL aggregates. This mixed aggregate LIB has excellent performance in controlling the release of drugs. For single CL aggregate, approximately 62.5% DOX was released after 72 h (pH - 7.4). However, LIB such as, (0.1 alpha(CL)+ 0.9 alpha(IBF)), the release of DOX decreased to 16.08%. Finally. LIB mixed aggregate applicability has been used to minimize the cytotoxicity of MCF-7 cells, and it has been found that DOX in UB mixed aggregates has a higher inhibitory effect on cell growth than DOX in CL.
