Manganese-based imaging probes Imaging of vesicular monoamine transporter 2 (VMAT2) Imaging of sulfonylurea receptor 1 (SUR1) In mammals, insulin secretion is mediated by the membrane potential of pancreatic β-cells. Increases in glucose levels lead to blocking of ATP-sensitive potassium ch

TGR5 Agonists FXR/TGR5 Dual Agonists In 2010, a FXR/TGR5 dual agonist, 51 (INT-767), was reported [57]. Using an AlphaScreen coactivator recruitment assay, the potency of 51 at FXR was 30nM. In NCI-H716 cells, 51 stimulated intracellular cAMP secretion with an EC50 of 0.63μM. Its TGR5 potency

Methods Results Discussion LPD, in terms of insufficient secretion of progesterone by the CL, reflected by low serum progesterone levels can occur in IVF attempts using any kind of ovarian stimulation protocol (Fatemi et al., 2007, Garcia et al., 1981, Van der Linden et al., 2011). However,

Next, we designed substituents of the 6-position. Edge-to-face aromatic interaction between aromatic ring of ligand and Phe162B needed to be retained because the interaction seems to be important for tight binding. 3′-Position of the 6-phenyl group of directs to a hydrophilic space where W1 exists.

In contrast to short-term effects, long-term exposure of beta cells to FFAs impairs insulin secretion and triggers apoptosis [13]. The deleterious effects of FFAs have been linked to altered glucose/fatty cytoskeleton oxidation cycle [13], decreased NADPH content [14], endoplasmic reticulum (ER) str

Ionotropic glutamate receptors (GluRs) are ligand-gated ion channels that mediate information processing at the majority of excitatory synapses in the brain and participate in such physiological processes as learning and memory, development and maintenance of cellular connections, and pain perceptio

Natural-product-based drug discovery can be enhanced with computational methods [205]. Because most of the reported small-molecule natural inhibitors of fMLF-induced functional responses were not evaluated in DS2 binding assays, we used molecular modeling to predict how well these compounds fit the

TRRAP participates in embryonic development, as demonstrated by its binding with proteins regulating the Notch signaling pathway in fruit fly, the Ras signaling pathway in C. elegans, or the Wnt signaling pathway in 293T cells. Therefore we suspect that TRRAP variants, more especially those falling

Apoptosis is one of critical toxic mechanisms of benzene metabolites. In this work, overexpression of HIF-1a could significantly reduce the increase in cell apoptosis caused by 40 μM BQ. At the meanwhile, anti-apoptotic protein Bcl-2 level was significantly elevated in HIF-1a overexpression cells th

In addition to SAHA, SBHA also showed a strong rescue effect. SAHA is a general inhibitor of HDAC function (Finnin et al., 1999, Kim and Bae, 2011), while SBHA is more specific, and has been shown to inhibit HDAC1 and HDAC3 (Richon et al., 1998). The relative level of suppression was similar in Kis

Cysteine (Cys) residues are frequently found to be highly conserved within functional, regulatory, catalytic, or binding sites of proteins. Thiol or thiolate chemistry imparts active sites with unique properties like nucleophilicity, high affinity metal binding, and disulfide bond assisted multimeri

Accessibility and physico-chemical features of cysteine residues define their redox-reactivity and the 3-dimensional structure of GSNOR allows to identifying such surface-exposed, redox-sensitive cysteine residues. GSNOR crystal structures are available from human (Protein Data Bank code: 1MP0), tom
