Formulations and devices, such as an OLEDs, that include the compound containing a structure of Formula I are also described.
摘要:
The present invention provides novel fluorescent dyes and kits containing the same, which are useful for labeling a wide variety of biomolecules, cells and microorganisms. The present invention also provides various methods of using the fluorescent dyes for research and development, forensic identification, environmental studies, diagnosis, prognosis and/or treatment of disease conditions.
摘要:
Provided are modified cycloalkyne compounds; and methods of use of such compounds in modifying biomolecules. Embodiments include a cycloaddition reaction that can be carried out under physiological conditions. The cycloaddition reaction involves reacting a modified cycloalkyne with an azide moiety on a target biomolecule, generating a covalently modified biomolecule. The selectivity of the reaction and its compatibility with aqueous environments provide for its application in vivo and in vitro.
摘要:
Embodiments relate to the field of chemistry and biochemistry, and, more specifically, to novel near-infrared dyes that are photostable and resistant to quenching. The dyes belong to a novel family of squaraine rotaxanes, and they are particularly well-suited for use in biological applications. Also disclosed are methods of synthesizing the dyes and methods of using the dyes.
摘要:

摘要:
The present invention relates to 17-oxymacbecin analogues that are useful, e.g. in the treatment of cancer, B-cell malignancies, malaria, fungal infection, diseases of the central nervous system and neurodegenerative diseases, diseases dependent on angiogenesis, autoimmune diseases and/or as a prophylactic pretreatment for cancer. The present invention also provides methods for the production of these compounds and their use in medicine, in particular in the treatment and/or prophylaxis of cancer or B-cell malignancies.
摘要:
A medical device comprising a substrate having a plasma polymerized functionality bonded to at least a portion of the substrate. A superoxide dismutase mimic agent having a complimentary functional group to the plasma polymerized functionality is bonded to the portion of the substrate by bonding to the plasma polymerized functionality. The functionalities can be carboxylate, amine, or sulfate groups and/or polyethylene glycol and can optionally include crosslinking groups.
摘要:
The present invention provides analogs of benzoquinone-containing ansamycins and uses thereof for treating and modulating disorders associated with hyperproliferation, such as cancer. The present invention provides analogs of benzoquinone-containing ansamycins where the benzoquinone is reduced to a hydroquinone and trapped by reaction with a suitable acid, preferably ones that increase the solubility and air stability of the resulting 17-ammonium hydroquinone ansamycin analog.
