Dendrimers: Emerging Anti-Infective Nanomedicines
Published in Bhupinder Singh, Rodney J. Y. Ho, Jagat R. Kanwar, NanoBioMaterials, 2018
For antimicrobial activity, dendrimers have been engineered sequentially as well as for surface topology. Recently, 1.0G and 3.0G PPI dendrimers have been modified by Grabchev et al. (2015) to develop metallodendrimer complexes with promising antimicrobial activity. In this research work, dendrimers were first modified with 4-amino-1, 8-naphthalimide units followed by formation of complexes with Cu (II) and Zn (II) metal ions. In vitro evaluation against the six strains of microorganisms (i.e. Bacillus subtilis, Micrococcus luteus, Pseudomonas aeruginosa, Acinetobacter johnsonii, E. coli, Saccharomyces cerevisiae and Candida lipolytica) showed that 3.0G metallodendrimer complexes showed comparatively higher antimicrobial activity compared to 1.0G metallodendrimer complexes. The schematic presentation of the chemical structure of 4-amino-1, 8-naphthalimide modified 3.0G poly (propylenamine) dendrimers, as well as 3.0G metallodendrimer complex is given in Figure 6.3 (Grabchev et al., 2015).

Metal particles such as Cu, Au, Ag, Pd, Pt, and Rh have been formed within poly(amidoamine)dendrimers (PAMAM).[3] The properties of metallodendrimer catalysts, such as stability, activity, and selectivity are based on the nature and location of the metal.[28] Since complexes of Cu2+ with polypropylene imine and PAMAM dendrimers have interpretable electron paramagnetic resonance and ultraviolet-visible spectra, the first researchers focused on Cu2+ ions encapsulated within dendrimers.[29]
