Synthesis and biological evaluation of glyco-GA compounds as anticancer agents

A series of novel glyco-gambogic acid（GA） compounds were synthesized and evaluated for their in vitro anti-proliferative activity against human hepatocellular carcinoma（HCC） cells.All compounds showed much better aqueous solubility（0.92- 1.89 mg/mL） than GA（0.013 mg/mL）,and displayed potent inhibition on HCC cells(IC₅₀:0.21-12.23μmol/L) and little affects on non-tumor liver cells(IC₅₀:42.56-86.43μmol/L),suggesting that glyco-GA compounds selectively inhibit HCC proliferation,and may be promising candidates for further intensive study.
