Taxol and other antimitotic agents are frontline chemotherapy agents but the mechanisms responsible for patient benefit remain unclear. Following a genome-wide siRNA screen, we identified the oncogenic transcription factor Myc as a taxol sensitizer. Using time-lapse imaging to correlate mitotic behavior with cell fate, we show that Myc sensitizes cells to mitotic blockers and agents that accele...
Cardiac glycosides are potent inhibitors of cell division. They may be useful as antitumor agents if the antimitotic effect can be dissociated from their cardiotoxic effect. We studied congeners of cardiac glycosides to determine whether the saccharide or the genin portion of the molecule contributes to its antimitotic effect. The concentration of glycoside required to inhibit PHA-stimulated 3H...
The results of artificial polyploidization for horticultural and agronomic plant species are presented in this review. The data on use of the classical antimitotic drug colchicine for chromosome doubling are reported. The efficacy of other compounds such as dinitroanilines and phosphorothioamidates in polyploidy induction as compared to colchicine has been summarized. The molecular basis of hig...
Data generated in the new National Cancer Institute drug evaluation program, which are based on inhibition of cell growth in 60 human tumor cell lines, were probed with nine known antimitotic agents using the COMPARE algorithm. Cytotoxicity data were available on approximately 7000 compounds at the time of the analysis, and, based on the criteria used, 82 compounds were selected as positive by ...
The synthesis of a previously undescribed sp3-rich 6-5-5-6 tetracyclic ring scaffold using a palladium catalysed domino Heck-Suzuki reaction is reported. This reaction is high-yielding, selective for the domino process over the direct Suzuki reaction and tolerant towards a variety of boronic acids. The novel scaffold can also be accessed via domino Heck-Stille and radical cyclisations. Compound...
