In this paper we synthesized a natural polymer based metal complex. The complex were characterize using different spectrochemical techniques like FT-IR, Mass spectroscopy and X-ray diffraction etc. The complex was found to be active towards different fungal, MIC80 was determined in vitro in liquid medium by the macro broth dilution method as per the guidelines of CLSI reference document M27-A3 for fungi, document NCCLS/CLSI M11-A6 for gram negative bacteria, and document CLSI M100-S15 for gram positive bacteria.  The order of sensitivity to these compounds was C. albicans > E. coli > S. aureus.

The unique properties associated with these dendrimers such as uniform size, high degree of branching, water solubility, multivalency, well-defined molecular weight and available internal cavities make them attractive for biological and drug-delivery applications. Commercialization of dendrimers is now forthcoming. A new dendrimeric ligand (L) was synthesized by the Michael addition of ethylenediamine to methyl methacrylate. The prepared ligand was complexed Cu (II) ions, the ligand and its complex were characterized by elemental analysis and spectroscopic studies (FT-IR, UV-Vis, 1H NMR and ESI-MS). Square pyramidal geometry was proposed for copper complexes, on the basis of UV-Vis spectroscopic data and molar conductance measurements. The dendrimer metal complex is active towards the oxidation of alcoholic substrates using molecular oxygen as substrate. The effect of various parameters on the rate of reaction is also explained.
