Jacques Poupaert et al.
Current medicinal chemistry, 12(7), 877-885 (2005-04-28)
The 2(3H)-benzoxazolone heterocycle and its bioisosteric surrogates (such as 2(3H)-benzothiazolinone, benzoxazinone, etc.) have received considerable attention from the medicinal chemists owing to their capacity to mimic a phenol or a catechol moiety in a metabolically stable template. These heterocycles and

New graphene-silk peptide (Gr-SP) nanosheets were prepared and successfully fabricated with tyrosinase (Tyr) as a novel biosensor for the determination of phenolic compounds. The Gr-SP nanosheets were fully characterized with transmission electron microscopy, x-ray diffraction, x-ray photoelectron spectroscopy, UV/Vis and

The treatment of diseased vasculature remains challenging, in part because of the difficulty in implanting drug-eluting devices without subjecting vessels to damaging mechanical forces. Implanting materials using adhesive forces could overcome this challenge, but materials have previously not been shown

Conjugation of mussel-inspired catechol groups to various polymer backbones results in materials suitable as silicon anode binders. The unique wetness-resistant adhesion provided by the catechol groups allows the silicon nanoparticle electrodes to maintain their structure throughout the repeated volume expansion

Occupational exposure to benzene has long been associated with toxicity to the blood and bone marrow, including lymphocytopenia, pancytopenia, aplastic anemia, acute myelogenous leukemia, and possibly lymphoma. A variety of studies have established that benzene itself is not the toxic
