Abstract:
The invention provides compounds, methods, pharmaceutical compositions, and kits for the treatment of proliferative disorders such as cancer. In one aspect, the methods comprise compounds that inhibit the activity of protein kinases, such as cell division cycle (Cdc) kinase. In another aspect, the methods comprise compounds that inhibit Cdc7 and/or Dbf4 activity. In another aspect, the methods comprise compounds that exhibit anti-proliferative properties useful in treating diseases such as cancer. Compounds useful for any of the methods include compounds of the Formula (A) or (B): or pharmaceutically acceptable salts thereof. Exemplary compounds of Formula (A) or (B) include granaticin A, granaticin B, dihydrogranaticin A, dihydrogranaticin B, medermycin, and actinorhodin.
Abstract:
Certain reducible compounds are useful in analytical compositions, elements and methods, for example for the detection of bacterial cells. These compounds comprise a moiety which provides a leuco dye upon reduction. This lecuo dye can then be oxidized with additional molecules of reducible compound in order to provide a detectable dye. Thus, these reducible compounds are considered bioamplifiers from which a multiplicity of dye molecules can be provided from a single reducible compound molecule. Structurally, the reducible compounds are quinones having suitable substituents which promote varying amounts of leuco dye release at physiological pH.

Abstract:
Electrowetting apparatus including a compound comprising a plurality of colorant moieties and a linker. The plurality of colorant moieties includes a first colorant moiety having a first net dipole and a second colorant moiety having a second net dipole, wherein the plurality of colorant moieties are linked by and disposed around the linker so that the first net dipole and the second net dipole at least partially cancel each other.
