Rutaecarpine is a quinazolinocarboline alkaloid of the medicinal herb Evodia rutaecarpa and shows a variety of pharmacological effects. Four oxidation metabolites of rutaecarpine were prepared from 3-methylcholanthrene-treated rat liver microsomes. These metabolites had an [M + H]+ ion at m/z 304. The structures of metabolites were identified by comparison(More)
Neo-tanshinlactone (1) was isolated and synthesized for the first time and evaluated in vitro against several human cancer cell lines. Compound 1 showed significant inhibition against two ER+ human breast cancer cell lines and was 10-fold more potent and 20-fold more selective as compared to tamoxifen citrate. Compound 1 also potently inhibited an ER-,(More)
A series of 4,5-diarylisoxazoles related to combretastatin A-4 (CA-4) were synthesized and evaluated for cytotoxicity against three human cancer cell lines. Among them, compound 6e showed better cytotoxic activity than CA-4 in HeLa and HepG2 cell lines assayed with IC(50) value as low as 0.022 and 0.065nM, respectively.
LY395153 is a member of a newly described class of arylpropylsulfonamide AMPA receptor potentiators. Here, we characterize and compare [(3)H]LY395153 binding to native AMPA receptors from rat cerebral cortex and recombinant human GluR4(flip) receptors expressed in HEK293 cells. L-Glutamate and AMPA increased [(3)H]LY395153 binding to both native and(More)
Murine melanoma B16-F1 cells of low metastatic potential were transfected with the human gene for the prepro form of urokinase in an SV40 expression vector (plasmid pSV2-uPA), and cells expressing high amounts of the human urokinase gene product were selected for by an enzyme-linked immunosorbent assay specific for human high molecular weight urokinase.(More)
