Abstract

A new series of anthracene-9, 10-dione derivatives have been synthesized to increase cytotoxic activity against human papillomavirus (HPV) positive Cancer cell line, CaSki. The highest cytotoxicity was achieved by 4-(benzylamino)-9,10-dioxo-4a,9,9a,10-tetrahydroanthracen-1-yl 4-ethylbenzenesulfonate (5) with the inhibitory concentration 50 (IC50) of 0.3 μM which is 20 times lower than that of cisplatin (CDDP; IC50 = 8.0 μM). The toxicity against non-cancerous cell line, WI-38, was low with the IC50 > 10 μM. Treatment with this compound resulted in decreasing HPV E6 expression. Furthermore, increasing p53 and decreasing Bcl-2 expression were noted. Cell cycle profiles revealed an accumulation of cells in the G2/M phase.
