Objective: The design and development of Combretastatin A-4 analogues as anticancer agent has always attracted the attention of scientific community involved in anticancer research. The aim of the present work was to investigate the in-vivo cytotoxic activity of a novel CA-4 analogues i.e., (2-amino-3,4,5-trimethoxyphenyl)(6-methoxy-1H-indol-3-yl)methanone.

Method: The in-vivo cytotoxic activity of test compound was examined using Human Tumor Xenograft model on MCF-7 cancer cell line in Balb/c mice.

Result: The test compound exhibited excellent cytotoxic activity against MCF-7 (0.013 µM), and colon HT-29 (0.143 µM), slightly higher than CA-4 activity. Relative Tumor Volume (RTV) value was found to increase rapidly in control group A during the period of 1 to 18 days indicating the higher growth rates of tumor. On the other hand group B and C showed slower growth rate of tumor as a result of treatment with CA-4 and test compound, respectively. The group B treated with CA-4 (5 mg/kg) showed significant inhibition in tumor growth during day 5 to 18 with %TGI in range of 47.24%-62.31% as compared to control group. The group C treated with test compound  (5mg/kg) caused significant inhibition in tumor growth during day 5 to 18 with %TGI in range of 55.66%-75.93% as compared to control group. The % survival value was found 100% indicating that CA-4 and test compound were nontoxic at the dose of 5mg/kg under experimental conditions.

Conclusion: The parameters of In-vivo anticancer evaluation i.e., relative tumour volume and % tumor growth inhibition showed better anticancer potential of test compound. It was further supported by non-toxic nature of test compound as indicated by 100% survival value determined at the dose of 5 mg/kg during in-vivo studies.
