Lead identification of a potent benzopyranone selective estrogen receptor modulator
摘要:
Starting from a phenol screening hit (6), three series of benzopyranone selective estrogen receptor modulators (SERMs) have been designed, synthesized, and analyzed for both estrogen receptor alpha binding affinity and in vitro activity in two cell assays. The lead compound identified, SP500263 (13), was more potent than raloxifene and tamoxifen in a cell-based assay measuring inhibition of interleukin-6 release. (C) 2004 Elsevier Ltd.

Design, synthesis, and anti-tumor activities of novel triphenylethylene–coumarin hybrids, and their interactions with Ct-DNA
摘要:
Novel triphenylethylene-coumarin hybrid derivatives containing different amounts of amino side chains Were designed and synthesized in good yields under microwave radiation. The derivatives 5b-d which possessed two amino side chains (except morpholinyl) showed a broad-spectrum and good anti-proliferative activity against five tumor cells and low cytotoxicity in osteoblast. UV-vis, fluorescence, and circular dichroism (CD) spectroscopies and thermal denaturation exhibited that compounds 10c, 5c, and 13c bearing amino side chain (except morpholinyl) on 4-phenyl had significant interactions with Ct-DNA by the intercalative mode of binding. Structure-activity relationships (SARs) analysis suggested that the amino alkyl chain would play an important role both in the compounds against tumor cells proliferation and their interactions with DNA.
