  Cytotoxic 2′,5′-dihydroxychalcones with unexpected antiangiogenic activity

  摘要：

  A series of 2',5'-dihydroxychalcones were synthesized and evaluated for cytotoxicity against tumor cell lines and human umbilical venous endothelial cells (HUVEC). It was found that chalcones with electron-withdrawing substituents on the B ring exhibited potent cytotoxicity against a variety of tumor cell lines while compounds with electron-releasing groups ere less potent in general. Those compounds with B ring replaced by extended or heteroaromatic rings exhibited significant bioactivity. Several compounds were shown to have marked cytotoxic selectivity towards HUVECs. Especially, among the synthesized compounds. 2-chloro-2'.5'dihydroxychalcone (2-3) showed the highest selectivity index up to 66 in comparison to HCT 116 cells. This Compound also exhibited strong inhibitory effects on the HUVEC tube formation in an in vitro model. When administered into BDF1 mice bearing Lewis lung carcinoma cells at 50 mg kg(-1) day (-1), 2-3 was found to inhibit the growth of tumor mass by 60.5%.

  4-Dimethylamino-2′,5′-dihydroxychalcone (DMADHC), a typical compound that exhibits excited-state intramolecular charge-transfer (ICT) characteristics and possesses good photophysical properties, is synthesized and used as fluoroionophore for a Fe3+ sensitive optochemical sensor. The sensor shows a linear response toward Fe3+ in the concentration range of 3.984×10−7–1.135×10−5 M with a limit of detection of 8.223×10−9 M. It exhibits excellent selectivity for Fe3+ over a large number of cations such as alkali, alkaline earth, and transitional-metal ions.
