Intramolecular cyclopropene-furan [2 + 4] cycloaddition followed by a cyclopropylcarbinyl rearrangement to synthesize the BCD rings of cortistatin A.

Sep 2009 Synthesis of the BCD ring system of cortistatin A has been accomplished in 9 steps and 30% overall yield starting from commercially available 2-methylcyclopent-2-enone. Key transformations include the addition of cyclopropenyllithium 16 to aldehyde ... Read more...

Effects of 15-deoxy-delta 12, 14-prostaglandin J2 on the expression of p53 in MCF-7 cells.

30 Jul 2009 Cyclopentenone prostaglandins (cyPGs) exert diverse cellular functions, such as anti-inflammatory and cytoprotective effects, via multiple mechanisms. CyPGs, especially those of the A and J series, are characterized by the presence of a chemically ... Read more...

Control and characterization of cyclopentene unimolecular dissociation on Si(100) with scanning tunneling microscopy.

27 Jul 2009 Dissociation of individual cyclopentene molecules on the Si(100) surface is induced and investigated using cryogenic ultrahigh vacuum scanning tunneling microscopy (STM). Using a secondary feedback loop during elevated tunneling current and sample ... Read more...
