SYNTHESIS, CHARACTERISATION AND DNA PHOTOCLEAVAGE ACTIVITY OF NEW 2-(THIOXO/OXO) QUINOLINE-4,6-DIMETHYL PYRIMIDINYL HYDRAZONES
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2014, Vol 6, Issue 9
Abstract
Objective: The main objective of present work is to synthesize, characterize and evaluate DNA photocleavage activity of hydrazones containing quinoline and pyrimidine rings.Methods: The syntheses of new 2-(Thioxo/Oxo)quinoline-4,6-dimethyl pyrimidinyl hydrazones has been achieved by the reaction of 2-(Thioxo/Oxo)quinoline-3-carbaldehydes and 2-hydrazino-4, 6-dimethylpyrimidine. The structure of synthesized compounds is established on basis of data obtained from the spectroscopic techniques such as 1H NMR, 13C NMR, FT-IR and mass. The synthesized compounds were evaluated for their DNA photocleavage activity at 40 μg/μl concentration by agarose gel electrophoresis method.Results: The synthesized compounds 5e showed complete cleavage of DNA while 5a, 5b and 6e showed significant cleavage potential.Conclusion: A series of novel hydrazones bearing quinoline and pyrimidine moiety has been synthesized and well characterized on the basis of spectroscopic data and further evaluated for their DNA photocleavage activity. It has been observed that compounds having bromo and thio group displayed good activity.
