LYSC_CHICK Lysozymes have primarily a bacteriolytic function; those in tissues and body fluids are associated with the monocyte-macrophage system and enhance the activity of immunoagents. Has bacteriolytic activity against M.luteus.^[1]

Publication Abstract from PubMed

We report on platinum(ii) complexes with different cinnamic acid derivatives as ligands with cytotoxic activity against Cisplatin resistant ovarian cancer cell line subcultures of SKOV3 and A2780. A typical mechanism of action for platinum(ii) complexes as Cisplatin itself is binding to the DNA and inducing double-strand breaks. We examined the biological behavior of these potential drugs with 9-methylguanine using NMR spectroscopic methods and their DNA damage potential including gammaH2AX-foci analyses. X-ray diffraction methods have been used to elucidate the molecular structures of the platinum(ii) complexes. Interactions with the model protein lysozyme have been evaluated by different techniques including UV-Vis absorption spectroscopy, fluorescence and X-ray crystallography.
