Analysis of GAL3 and Lactose functionalized PAMAM Binding by EPR
MetadataShow full item record
In order to better understand the binding characteristics between lactose functionalized PAMAM dendrimers and the galactoside lectin Galectin-3, the synthetic production of heterogeneously functionalized TEMPO and Lactose PAMAM dendrimers were undertaken. To analyze the relevant lectin/ carbohydrate relationship, these dendrimers will be subjected to electron pair repulsion (EPR) studies. The implication of analyzing several dendrimer generations through EPR is that a quantitative understanding of the relationship between dendrimer size/ degree of functionalization and binding strength can be determined. In terms of progress, a significant portion of the synthesis has been completed. Optimized yields have been determined and characterization has been completed on the reactions that lead to the production of the Lactose tether.
