Insulin-mimetic action of vanadium compounds on osteoblast-like cells in culture
(1997)
Vanadium compounds mimic insulin actions in different cell types. The present study concerns the insulin-like effects of three vanadium(V) derivatives and one vanadium(IV) complex on osteoblast-like (UMR106 and MC3T3E1) ...
Identification of a potent activator of Akt phosphorylation from a novel series of phenolic, picolinic, pyridino, and hydroxamic zinc(II) complexes
(2011)
The discovery of small-molecule modulators of signaling pathways is currently a particularly active area of research. We aimed at developing unprecedented metal-based activators of Akt signaling which can potentially find ...
ICPBCZin: A red emitting ratiometric fluorescent indicator with nanomolar affinity for Zn2+ ions
(2008)
A new fluorescent Zn2+ indicator, namely, ICPBCZin was synthesized and the spectral profile of its free and Zn2+ bound forms was studied. The newly synthesized zinc indicator incorporates as chromophore the chromeno ...
Combined chemical and optical methods for monitoring the early decay stages of surrogate human models
(2011)
As the body decays shortly after death, a variety of gases and volatile organic compounds (VOCs) constantly emanate. Ethical and practical reasons limit the use of human corpses in controlled, time-dependent, intervening ...
Direct detection of Fe(IV)=O intermediates in the cytochrome aa3 oxidase from Paracoccus denitrificans[H2O2 reaction
(2003)
We report the first evidence for the formation of the "607- and 580-nm forms" in the cytochrome oxidase aa3/H2O2 reaction without the involvement of tyrosine 280. The pKa of the 607-580-nm transition is 7.5. The 607-nm ...
The role of the cross-link His-Tyr in the functional properties of the binuclear center in cytochrome c oxidase
(2002)
Resonance Raman and Fourier transform infrared spectroscopies have been used to study the aa3-type cytochrome c oxidase and the Y280H mutant from Paracoccus denitrificans. The stability of the binuclear center in the absence ...
FOXO3a is broadly neuroprotective in vitro and in vivo against insults implicated in motor neuron diseases
(2009)
Aging is a risk factor for the development of adult-onset neurodegenerative diseases. Although some of the molecular pathways regulating longevity and stress resistance in lower organisms are defined (i.e., those activating ...
Hydrophilic cationic star homopolymers based on a novel diethanol-n-methylamine dimethacrylate cross-linker for sirna transfection: Synthesis, characterization, and evaluation
(2011)
Four cationic hydrophilic star homopolymers based on the novel hydrophilic, positively ionizable cross-linker bis(methacryloyloxyethyl)methylamine (BMEMA) were synthesized using sequential group transfer polymerization ...
Nitric-oxide reductase: Structure and properties of the catalytic site from resonance Raman scattering
(2002)
We have applied resonance Raman spectroscopy to investigate the properties of the dinuclear center of oxidized, reduced, and NO-bound nitric-oxide reductase from Paracoccus denitrificans. The spectra of the oxidized enzyme ...
Novel lipophilic amidate oxorhenium and oxotechnetium complexes as potential brain agents: Synthesis, characterization and biological evaluation
(2001)
Novel oxorhenium and oxotechnetium complexes based on the tetradentate 1-(2-hydroxybenzamido)-2-(pyridinecarboxamido)benzene, H3L, ligand have been synthesized and characterized herein. Thus, by reacting equimolar quantities ...
