In vivo anticancer activity of vanillin semicarbazone

OBJECTIVE To evaluate the anticancer activity of vanillin semicarbazone (VSC) against Ehrlich ascites carcinoma (EAC) cells in Swiss albino mice. METHODS The compound VSC at three doses (5, 7.5 and 10 mg/kg i.p.) was administered into the intraperitoneal cavity of the EAC inoculated mice to observe its efficiency by studying the cell growth inhibition, reduction of tumour weight, enhancement of survival time as well as the changes in depleted hematological parameters. All such parameters were also studied with a known standard drug bleomycin at the dose of 0.3 mg/kg (i.p.). RESULTS Among the doses studied, 10 mg/kg (i.p.) was found to be quite comparable in potency to that of bleomycin at the dose of 0.3 mg/kg (i.p.). The host toxic effects of VSC was found to be negligible. CONCLUSIONS It can be concluded that VSC can therefore be considered as potent anticancer agent.

Antimicrobial Activity of Some Schiff Bases Derived from Benzoin, Salicylaldehyde, Aminophenol and 2,4 Dinitrophenyl Hydrazine

The antibacterial and antifungal activities of three schiff bases were evaluated against some pathogenic bacteria and fungi. Parallel experiments were also carried out with standard drugs (Kanamycin for bacteria and Nystatin for fungi). Two compounds [N-(1-phenyl-2-hydroxy-2phenylethylidine)-2‘,4’ dinitrophenyl hydrazine, abbreviated as PDH and N-(2-hydroxy benzylidine)-2’-hydroxy imine, abbreviated as HHP] showed significant antimicrobial activities. The rest one [N-(1-phenyl 2-hydroxy-2 phenyl ethylidine) 2’-hydroxy phenyl imine, abbreviated as PHP] showed moderate activity. All these three compounds were found to possess pronounced cytotoxic effect. These compounds can be considered as potent antimicrobial agents.

Anti-inflammatory and analgesic activities of acetophenone semicarbazone and benzophenone semicarbazone

Abstract Objective To study anti-inflammatory and analgesic activities in swiss albino mice, two schiff bases namely acetophenone semicarbazone (ASC) and benzophenone semicarbazone (BSC) were synthesized and characterized. Methods Two doses of the test compounds 25 and 50 mg/kg (p.o) for each were selected throughout the research work. The anti-inflammatory activity of the test compounds was determined by ‘carragenan induced mice paw edema inhibition’ method. The analgesic activity was determined by both, ‘acetic acid induced writhing’ and ‘tail immersion’ methods. All such data were compared with standard drugs at the dose of 10 mg/kg (p.o.). Results Both ASC and BSC have showed positive effects as anti-inflammatory and analgesic agents. Anti-inflammatory and analgesic activities of the test compounds at 50 mg/kg (p.o.) were quite comparable to those of standard drugs at 10 mg/kg (p.o.). Conclusion Both ASC and BSC can be considered as potent anti-inflammatory and analgesic agents.

ANTINEOPLASTIC ACTIVITIES OF ACETONE THIOSEMICARBAZONE AGAINST EHRLICH ASCITES CARCINOMA CELLS BEARING MICE

SUMMARY: A schiff base acetone semicarbazone has been synthesized and characterized. Its anticancer activities have been studied against Ehrlich Ascites Carcinoma (EAC) cells in swiss albino mice by monitoring the parameters like tumour cell growth inhibition, tumour weight, survival time, peritoneal cells and haematological parameters. It was found that this compound significantly reduces tumour cell growth rate, decreases tumour weight and increases life span in comparison to those of EAC bearing mice. The test compound restored the depleted haematological parameters of EAC bearing mice towards normal. The compound also enhanced number of macrophages in normal mice. The results obtained were compared with those obtained with the standard drug bleomycin.

In Vivo Anticancer Activities of Vanillin Thiosemicarbazone Complexes with Co ( II ) and Ni ( II )

Sha M. S. Shahriar Department of Applied Chemistry and Chemical Engineering, University of Rajshahi, Rajshahi-6205, Bangladesh. e-mail: shahan.acrubd@yahoo.com ABSTRACT The anticancer activities of vanillin thiosemicarbazone complexes with Co(II) and Ni(II) have been studied against Ehrlich ascites carcinoma (EAC) cells in Swiss albino mice. Both the complexes were administrated into the intraperitoneal cavity of the EAC-inoculated mice at two doses (5 and 7.5 mg/kg i.p.). The anticancer activities were studied by monitoring the parameters such as cell growth inhibition, tumor weight measurement, survival time of EAC-bearing mice, as well as the changes in depleted hematological parameters due to tumorigenesis. All data were compared with those of a known standard drug bleomycin at the dose of 0.3 mg/kg (i.p.). It has been found that these complexes significantly increased the life span of tumor-bearing mice and decreased the rate of growth and weight of tumor cells. They also restored modestly the depleted hematological parameters such as hemoglobin content, RBC count, and WBC count to normal. They enhanced the number of macrophages in normal mice with minor host toxicity. It is concluded that these compounds can be primarily considered as potent anticancer agents.
