Infrared spectroscopy for biopharmaceutical protein analysis.

J Pharm Biomed Anal 2010,Sep,21;53(1):29-36; (PMID: 20381986)
[...]A mid-infrared transmission spectroscopic method with the possibility of high sample throughput was developed and validated on the basis of GMP requirements for protein therapeutics. In comparison with the method predominantly used, i.e. the surface-sensitive attenuated total reflection (ATR), we have shown that transmission measurements in solution possess several advantages, such as quantitative analysis on the basis of Lambert-Beer's law, determination of identity and purity based on specifically developed identity criteria, characterization of protein structure and structural changes including aggregation in solution and study of [...]

Impaired calcium influx despite hyper-reactivity in contralateral carotid following balloon injury: eNOS involvement.

Eur J Pharmacol 2010,Sep,10;642(1-3):121-7; (PMID: 20540939)
[...]Results obtained with L-NNA, 1400W, 7-NI, OxyHb, ODQ or Tiron showed that this response was mediated by products from endothelial NOS (eNOS) different from NO and without soluble guanylate cyclase activation, but it involved superoxide anions. Furthermore, Tiron or L-NNA reduced the levels of reactive [...]

Gastroprotective effect of heme-oxygenase 1/biliverdin/CO pathway in ethanol-induced gastric damage in mice.

Eur J Pharmacol 2010,Sep,10;642(1-3):140-5; (PMID: 20638948)
[...] product), dimanganese decacarbonyl (DMDC, CO donor) or zinc protoporphyrin IX (ZnPP IX, HO-1 antagonist). Another group received soluble guanylate cyclase (sGC) inhibitor (ODQ) 30 min before hemin, biliverdin or DMDC. After 30 min, gastric[...]

Cyclic 3', 5' guanosine monophosphate and larval midgut ecdysone 20-monooxygenase activity of the tobacco hornworm, Manduca sexta.

Comp Biochem Physiol B Biochem Mol Biol 2010,Sep,01;157(1):33-8; (PMID: 20451652)
[...] elevated E20M activity. In vivo, the 50-fold increase in E20M activity was diminished by injections of guanylate cyclase inhibitors alone or combined with RH-5849. Guanylate cyclase inhibitor effects were significantly diminished when co-injected with dibutyryl [...]

Endothelium-dependent contraction induced by acetylcholine in the chicken ductus arteriosus involves cyclooxygenase-1 activation and TP receptor stimulation.

Comp Biochem Physiol A Mol Integr Physiol 2010,Sep,01;157(1):28-34; (PMID: 20488253)
[...], the H2O2 scavenger PEG-catalase, the nitric oxide synthase inhibitor L-NAME, or the soluble guanylate cyclase inhibitor ODQ. Enzyme immunoassay determined that, under basal conditions, the chicken DA produced PGE2[...]

Systemic administration of GMP induces anxiolytic-like behavior in rats.

Pharmacol Biochem Behav 2010,Sep,01;96(3):306-11; (PMID: 20566406)
[...]In the present study, we investigated the anxiolytic effect of GBPs - by Guanosina Monophosphate (GMP) administration - in rodents. Adult male Wistar rats were pretreated with GMP[...]

PKG is involved in testosterone-induced vasorelaxation of human umbilical artery.

Eur J Pharmacol 2010,Aug,25;640(1-3):94-101; (PMID: 20444426)
[...] stimulate the activity of BKCa and KV channels due to PKG activation and suggest that this hormone relaxes by activating particulate guanylate cyclase which increases the cGMP intracellular level.

Fluoroquinolones as potential photochemotherapeutic agents: covalent addition to guanosine monophosphate.

Org Biomol Chem 2010,Aug,21;8(16):3621-3; (PMID: 20571620)
[...]The triplet aryl cation photochemically generated from fluoroquinolones bearing a fluoro atom at position 8 attacks guanosine monophosphate (k(r) > 10(9) M(-1)s(-1)) and forms covalent adducts. The reaction is a model for the implementation of oxygen-independent [...]

Ion-pair high-performance liquid chromatography with diode array detection coupled to dual electrospray atmospheric pressure chemical ionization time-of-flight mass spectrometry for the determination of nucleotides in baby foods.

J Chromatogr A 2010,Aug,06;1217(32):5197-203; (PMID: 20580011)
[...]/ESI-APCI-TOF-MS) method is described for the rapid determination of five monophosphate nucleotides (cytidine 5'-monophosphate, uridine 5'-monophosphate, adenosine 5'-monophosphate, inosine 5'-monophosphate and guanosine 5'-monophosphate) in baby foods. The method is based on the deproteinisation of foods and direct analysis of nucleotides by ion-pair [...]

Oriented Single-Crystal Nuclear Resonance Vibrational Spectroscopy of [Fe(TPP)(MI)(NO)]: Quantitative Assessment of the trans Effect of NO.

Inorg Chem 2010,Aug,02;49(15):7197-215; (PMID: 20586416)
[...] (His) ligand and NO. This is key for the activation of the NO sensor soluble guanylate cyclase. Finally, DFT methods are calibrated against the experimentally determined vibrational properties of the Fe-N-O subunit in 1.[...]
