OBJECTIVE: To find out the effective anticancer drugs from bacterial products, petroleum ether extract of Corynebacterium xerosis. METHODS: Antiproliferative activity of the metabolite has been measured by monitoring the parameters like tumor weight measurement, tumor cell growth inhibition in mice and survival time of tumor bearing mice, etc. Hepatoprotective effect of the metabolites was determined by observing biochemical, hematological parameters. RESULTS: It has been found that the petroleum ether extract bacterial metabolite significantly decrease cell growth (78.58%; P<0.01), tumor weight (36.04 %; P<0.01) and increase the life span of tumor bearing mice (69.23%; P<0.01) at dose 100 mg/kg (i.p.) in comparison to those of untreated Ehrlich ascites carcinoma (EAC) bearing mice. The metabolite also alters the depleted hematological parameters like red blood cell, white blood cell, hemoglobin (Hb%), etc. towards normal in tumor bearing mice. Metabolite show no adverse effect on liver functions regarding blood glucose, serum alkaline phosphatases, glutamic pyruvic transaminase, glutamic oxaloacetic transaminase activity and serum billirubin, etc. in normal mice. Histopathological observation of these mice organ does not show any toxic effect on cellular structure. But in the case of EAC bearing untreated mice these hematological and biochemical parameters deteriorate extremely with time whereas petroleum ether extract bacterial metabolite receiving EAC bearing mice nullified the toxicity induced by EAC cells. CONCLUSION: Study results reveal that metabolite possesses significant antiproliferative and hepatoprotective effect against EAC cells.
