摘要

One of the ways of reducing the amount of antibiotics is to add a phytochemical which would produce a synergistic interaction with the former. Effect of combination of cinnamic acid and amikacin against E.coli is reported in this naper. Checkerboard assay indicated that the amount of antibiotic could be reduced by a factor of 5 by adding 1mM of the phytochemical. Time kill curve studies indicated a twofold decrease in colony forming units when the two compounds were used in combination, when compared to them being used individually. The post antibiotic effect (i.e., persistant suppression of bacterial growth following a brief exposure to an antibiotic) of amikacin was enhanced when cinnamic acid was used. This study indicates that cinnamic acid acts synergistically with amikacin, indicating that the therapeutic dose of the later could be considerably decreased leading to reduction in its toxicity and prevention of drug resistance.
