Design of potent thiophene inhibitors of polo-like kinase 1 with improved solubility and reduced protein binding

A series of thiophene PLK1 inhibitors was optimized for increased solubility and reduced protein binding through the appendage of basic amine functionality. Interesting selectivity between PLK1 and PLK3 was also obtained through these modifications.

Discovery of thiophene inhibitors of polo-like kinase

The discovery and development of a series of thiophenes as potent and selective inhibitors of PLK is described. Identification and characterization of 2, a useful in vitro PLK inhibitor tool compound, is also presented.

Discovery of a novel and potent series of dianilinopyrimidineurea and urea isostere inhibitors of VEGFR2 tyrosine kinase

A series of dianilinopyrimidineureas demonstrate potency as VEGFR2 kinase inhibitors.

Free radical-mediated vinyl amination: access to N,N-dialkyl enamines and their beta-stannyl and beta-thio derivatives

[reaction: see text] The first examples of free radical-mediated vinyl amination are described by nonconventional vinyl radical addition to azomethine nitrogen. This new vinyl amination protocol is mild and provides convenient synthetic access to nonstabilized N,N-dialkyl enamines and tandem bond-forming processes.
