Studies of the physiological actions of melatonin have been hindered by the lack of specific, potent and subtype selective agonists and antagonists. In the present study, we describe the utility of a melanophore cell line from Xenopus laevis for exploring structure-activity relationships among novel melatonin analogues and report a novel MT2-selective agonist (IIK7) and MT2-selective receptor a...
most of the biological phenomena are influenced by intermolecular recognition and interaction. thus, understanding the thermodynamics of biomacromolecule ligand interaction is a very interesting area in biochemistry and biotechnology. one of the most powerful techniques to obtain precise information about the energetics of (bio) molecules binding to other biological macromolecules is isothermal...
The AR (androgen receptor) is known to influence the expression of its target genes by binding to different sets of AREs (androgen-response elements) in the DNA. One set consists of the classical steroid-response elements which are partial palindromic repeats of the 5'-TGTTCT-3' steroid-receptor monomer-binding element. The second set contains motifs that are AR-specific and that are proposed t...
the way to overcome current limitations in the generation of glucose-responsive insulin-producing cells is selective enrichment of the number of definitive endoderm (de) progenitor cells. sox17 is the marker of mesendoderm and definitive endoderm. the aim of the present research was to study the potential of sox17 knock-in cgr8 mouse embryonic stem (es) cells to differentiate into insulin produ...
Glutamate/N-methyl-d-aspartate (NMDA) receptor-mediated neurotoxicity involves cyclooxygenase (COX)-2. We demonstrate that this neurotoxicity reflects activation of COX-2 by S-nitrosylation after selective binding of neuronal nitric oxide synthase (nNOS) to COX-2. nNOS, via its PDZ domain, binds COX-2 with the generated NO S-nitrosylating and activating the enzyme. Selective disruption of nNOS-...
Nanowire field effect transistors (NW-FETs) can serve as ultrasensitive detectors for label-free reagents. The NW-FET sensing mechanism assumes a controlled modification in the local channel electric field created by the binding of charged molecules to the nanowire surface. Careful control of the solution Debye length is critical for unambiguous selective detection of macromolecules. Here we sh...
Target selective drugs, such as dopamine receptor (DR) subtype selective ligands, are developed for enhanced therapeutics and reduced side effects. In silico methods have been explored for searching DR selective ligands, but encountered difficulties associated with high subtype similarity and ligand structural diversity. Machine learning methods have shown promising potential in searching targe...
Plastic Antibodies for Selective Binding of SARS-CoV-2 Spike In article number 2101925, Alex D. Batista, Beatriz Fresco-Cala, and co-workers design synthesize the very first silane-based silica core/shell molecularly imprinted polymers using an epitope peptide from spike protein as a template, which can act synthetic angiotensin-converting enzyme 2 receptor (ACE2) bind to SARS-CoV-2. The intera...
Selective serotonin reuptake inhibitors (SSRIs) are associated with significant sexual side effects. By definition, all SSRIs increase overall serotonin (5HT) by binding to serotonin autoreceptors (5HT(IA)); however, each SSRI has a unique portfolio of secondary binding properties to other neurotransmitters such as norepinephrine (NE). As 5HT(IA) receptors mediate NE neurotransmission, SSRIs th...
Anti-adhesive glycoclusters offer potential as therapeutic alternatives to classical antibiotics in treating infections. Pillar[5]arenes functionalised with either five galactose or five fucose residues were readily prepared using CuAAC reactions and evaluated for their binding to three therapeutically relevant bacterial lectins: LecA and Lec B from Pseudomonas aeuruginosa and BambL from Burkho...
