The article report on new tetraamidometllophthalocyanines (2,9,16,23-tetra-N-[4-(1H-benzimidazol-2yl) phenyl] benzamido- metallophthalocyanines) have been synthesized and were characterized by elemental analysis, FTIR,1 H NMR, UV-VIS spectral data. The antioxidant activities of phthalocyanines were investigated by in vitro antioxidant assays such as free radical scavenging ability of 1,1-diphenyl-2-picrylhydrazyl (DPPH). The soluble conjugates metallophthalocyanines were screened against a wide range of Gram-positive and Gram-negative bacteria showed modest zone of inhibition and MIC with standard drug was investigated.
