ABSTRACT
Current anti-cancer drug therapy results in systemic side effects due to non-specific uptake by normal healthy noncancerous tissues. To alleviate this difficulty, many attempts have been devoted to the development of new delivery systems such as polymeric Nanoparticles [NPs]. In this study, we prepared ICD-85 NPs based on sodium alginate and analyzed the cytotoxic activity of ICD-85 NPs relative to free ICD-85 on primary lamb kidney cells. ICD-85 loaded sodium alginate nanoparticles were prepared by ionic gelation method and were characterized by the particle size, size distribution and Fourier Transform Infrared [FT-IR] spectroscopy. The in vitro cytotoxicity was evaluated by MTT assay and membrane integrity was evaluated by measuring Lactate Dehydrogenase [LDH] activity. The morphological alterations of untreated and treated cells were assessed by light inverted microscope. MTT assay showed that ICD-85 NPs could significantly decrease the in vitro cytotoxicity on primary lamb kidney cells compared to the free ICD-85. The IC[10] value at 72 hours was increased from 9 +/- 2.7 microg/ml for free ICD-85 to 52 +/- 4.3 microg/ml for ICD-85 NPs. LDH assay demonstrated that free ICD-85 had dose-dependent cytotoxicity on primary lamb kidney cells while ICD-85 NPs exhibited significantly decreased cytotoxicity at equivalent concentrations. Moreover, morphological analysis showed no significant difference between control and treated cells with ICD-85 NPs. Based on the results obtained in the present study it can be concluded that encapsulation of ICD-85 with sodium alginate nanoparticles can reduce its necrotic effect on primary lamb kidney cells
