EVALUATION OF IN VITRO CYTOTOXIC EFFECT OF VIOLACEIN PRODUCED BY NOVEL ISOLATE CHROMOBACTERIUM VACCINII CV5 AGAINST THE CERVICAL AND LUNG CANCER CELL
Keywords:Anticancer, Cytotoxicity, Chromobacterium, MTT assay, Pigment, Violacein
Â Objectives: This study investigates the in vitro anticancer activity of the violacein extracted from the Chromobacterium vaccinii CV5.
Methods: Natural colorants or dyes derived from flora to fauna are believed to be safe because of nontoxic, noncarcinogenic, and biodegradable in nature. There are a number of natural pigments, but only a few are available in sufficient quantities for industrial production. The cytotoxicity activity of pigment was assessed against the cervical (HeLa) and lung cancer (A549) cell lines using the MTT assay and there by potential cytotoxic activity exhibited by the pigment was identified.
Results: The result of the pigment shows potent anticancer activity on the two cancer cell lines tested in a concentration dependent manner. The potent anticancer activity was observed with the pigment with IC50 values of 26 Î¼g/mL on HeLa and 31 Î¼g/mL on A549 cells, respectively.
Conclusion: The study is pioneering report for determining the better in vitro anticancer activity of violacein from the novel isolate C. vaccinii CV5.
