摘要:
The present invention provides novel hydrosilation-curable compositions, the cure of which can be monitored visually, comprising: (1) an ethylenic compound; (2) a compound containing silicon-bonded-hydrogen groups; (3) a hydrosilation catalyst; and (4) one or more cure-indicating dyes with light absorption in the visible spectrum that exhibit a color change in the presence of a silicon-bonded-hydrogen compound and a precious metal hydrosilation catalyst. The cure-indicating dye provides the composition with an initial pre-cure color and a different post-cure color. As a result of this change in color, the state of cure of the composition can be visually monitored.
摘要:
An object of the present invention is to provide a cancer cell inhibitory drug, particularly a cancer stem-cell inhibitory drug, or a cancer stem-cell detection probe. The present invention provides a cancer cell inhibitory drug comprising at least one compound represented by general formula (1) as an active ingredient.
摘要:
The present invention provides heteroaryl functionalized cyanine dyes including a reactive functional moiety, or which are conjugated to a carrier molecule.
摘要:
A colored composition includes a pyrazolone methine dye having a solubility in n-hexane of 1% by mass or higher at 25°C and 0.1 MPa and represented by the following Formula (1), and a non-polar solvent at a content of 70% by mass or higher with respect to a total mass of the colored composition.
摘要:
Cyanines which selectively bind to G-quadruplex DNA complexes, particularly quadruplexes expressed in cancer cells, and methods of making and using thereof are described herein. The cyanine can be a symmetrical or unsymmetrical streptocyanine, hemicyanine, closed chain cyanine, or combinations thereof. The cyanine is preferably substituted with one or more groups that minimize or prevent aggregation of the cyanine and/or inhibit binding of the cyanine to duplex DNA. One or more of the cyanines can be formulated with one or more pharmaceutical excipients and/or carrier to prepare pharmaceutical compositions suitable for administration to a patient, particular a human patient. The compounds and compositions described herein can be used to treat diseases or disorders characterized by the expression of G-quadruplex DNA, such as cancer.
摘要:
The invention provides a novel class of cyanine dyes that are functionalized with sulfonic acid groups and a linker moiety that facilitates their conjugation to other species and substituent groups which increase the water-solubility, and optimize the optical properties of the dyes. Also provided are conjugates of the dyes, methods of using the dyes and their conjugates and kits including the dyes and their conjugates.
