A copper coordination compound ZZF51(A) named bis(5-butyl-2- pyridinecarboxylato-N1,O2)-copper, the first time found in the nature, was isolated from a marine endophytic fungus Fusarium sp. ZZF51 from the South China Sea coast. Its structure was elucidated using spectroscopic methods and single crystal X-ray diffraction analysis. The antimicrobial cytotoxicity experiments exhibited that ZZF51(A) had mutagenicity activities against four aerobic reference strains Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Salmonella enteritid...
