Influence of Riboflavin Targeting on Tumor Accumulation and Internalization of Peptostar Based Drug Delivery Systems.
Riboflavin carrier protein (RCP) and riboflavin transporters (RFVTs) have been reported to be highly overexpressed in various cancer cells. Hence, targeting RCP and RFVTs using riboflavin may enhance tumor accumulation and internalization of drug delivery systems. To test this hypothesis, butyl-based 3-arm peptostar polymers were synthesized consisting of a lysine core (10 units per arm) and a sarcosine shell (100 units per arm). The end groups of the arms and the core were successfully modified with riboflavin and the Cy-5.5 fluorescent dye, respectively. While in phosphate buffered saline the functionalized peptostars showed a bimodal behavior and formed supramolecular structures over tim…

Additional file 1: Figure S1. Zeta potential analysis of the crude, C1-C5, Resovist® and Sinerem® samples. Figure S2. Cell viability of NIH3T3 cells treated with the samples with various concentrations ofSPION for 4 h according to XTT assay. The data were normalized to control value (SPION-freemedia), which was set as 100% cell viability. Experiments were performed at different concentrationsof SPION in the range of 0.1 to 10.0 mM. Values represent means ± standard deviations of fiveidentical experiments made in three replicates. Figure S3. LDH leakage of NIH3T3 cells treated with the samples with various concentrations ofSPION for 4 h according to the manufacturer’s instructions. Experimen…
