Dansylated analogues of the potent and selective μ opioid peptide agonist [Dmt1]DALDA (H-Dmt-D-Arg-Phe-Lys-NH2; Dmt = 2',6'-dimethyltyrosine) were prepared either by substitution of Nβ-dansyl-α,β-diaminopropionic acid or Nε-dansyllysine for Lys4, or by attachment of a dansyl group to the C-terminal carboxamide function via a linker. All three analogues displayed high μ agonist potency in vitro and the C-terminally dansylated one retained significant μ receptor selectivity. The three analogues showed interesting differences in their fluorescence emission maxima and quantum yields, indicating that the dansyl group in two of them was engaged in intramolecular hydrophobic interactions. These dansylated [Dmt1]DALDA analogues represent valuable tools for binding studies, cellular uptake and intracellular distribution studies, and tissue distribution studies ...

An approach to the synthesis of conformationally restricted saturated heterocyclic sulfonyl chlorides is described. Being guided by the principle of diversity-oriented conformational restriction, a mini-library of saturated heterocyclic sulfonyl chlorides was designed and synthesized. The library consists of nine members that are derivatives of azetidine, pyrrolidine, and piperidine. These compounds were prepared in 19-88% total yields on multigram scale starting from the corresponding Cbz-protected amino alcohols.. ...
What this means: A protein can consist of 2 or more polypeptide chains that are linked together by disulfide bonds (see graphic below). For sequencing to properly work, you must break all protein subunits into individual strands.. N-terminal analysis of your protein provides information on the different types of subunits.. Since each polypeptide chain has an N-terminus (also known as the end group of a protein) it is possible to use a fluorescent compound such as 5-dimethylamino-1-naphthalenesulfonyl chloride (aka dansyl chloride) to cleave to the primary amine (N-terminal of a protein is the amine group). Quick Recap: N-terminal vs C-terminal of amino acids ...

Both complement and Fc regions of IgA 1 have been shown to enhance the uptake of antigens by antigen presenting cells (Fang, et. aI., 1998, Foged, et. aI., 2005, Perrin-Cocon, et. aI., 2004). However, the utilization of complement and IgA1 antibodies in enhancing the uptake of antigens by dendritic cells has not been examined to date. The aims of this research included attaching complement to antidansyl IgA 1 antibodies followed by induction, activation, and examination of dendritic cells incubated with the antigen-antibody immune complexes to determine potential interactive relationships. Complement was linked to the Fc region of anti-dansyl IgA 1 antibodies using a procedure to activate complement while the IgA 1 was bound to a dansylated Sepharose 4B affinity column. The eluted complement-coated IgA 1 antibodies were mixed with dansylated albumin to form the complement-coated IgA1-immune complexes. Then, the immune complexes were incubated with PBMCderived dendritic cells to induce maturation ...
A facile one-step Cu(I)-catalyzed click reaction, between a dansyl-azide and a propargyl-substituted rhodamine B hydrazide, is employed to fabricate a novel FRET ratiometric off-on fluorescent probe. The sensitive emission of the donor, a dansyl group, overlaps perfectly with the absorption of the acceptor, xanthene in the open-ring rhodamine. The proposed probe shows high selectivity towards Cu2+. The ratio of emission intensities at 568 and 540 nm (I-568/I-540) exhibits a drastic 28-fold enhancement upon addition of Cu2+. The probe shows an excellent linear relationship between emission ratios and the concentrations of Cu2+ from 10 to 50 mu M, with a detection limit (S/N = 3) of 0.12 mu M. The preliminary cellular studies demonstrated that the probe is cell membrane permeable and could be applied for ratiometric fluorescence imaging of intracellular Cu2+ with almost no cytotoxicity. The ingenuity of the probe design is to construct a FRET donor-acceptor interconnector and a selective ...

The chloride-chloride exchange reaction in arenesulfonyl chlorides was investigated experimentally and theoretically by density functional theory (DFT) calculations. The second order rate constants and activation parameters of this identity reaction were determined for 22 variously substituted arenesulfonyl chlorides using radio-labeled Et4N36Cl. The chloride exchange rates of 11 sulfonyl chlorides bearing para-and meta-substituents (σ constants from −0.66 to +0.43) in the aromatic ring followed the Hammett equation with a ρ-value of +2.02. The mono- and di-ortho-alkyl substituted sulfonyl chlorides exhibit an enhanced reactivity although both inductive and steric effects lower the reaction rate. The DFT calculations of their structures together with X-ray data showed that an increased reactivity is mainly due to a peculiar, rigid, strongly compressed and sterically congested structure. The DFT studies of the title reaction revealed that it proceeds via a single transition state

Fumonisins, carcinogenic mycotoxins produced by various Fusarium species, occur naturally in maize and maize-based food products. They are hazards for animal and human health as they cause cancer in rodents and have been associated with oesophageal cancer and neural tube defects in humans. The most abundant naturally occurring fumonisins analogues in maize are fumonisin B1, B2 and B3 (FB1, FB2 and FB3). For analytical determination, they mostly require suitable extraction, clean-up and pre or post-column derivatization together with reversed-phase HPLC separation. o- Phthaldialdehyde (OPA) had been adopted as the most widely used derivatization reagent for fumonisins as they lack useful chromophores or fluorophores. Alternative derivatization reagents, naphthalene-2,3- dicarboxaldehyde (NDA) and dansyl chloride (DnS-Cl), were investigated in this study ...

a) hydroxygallium naphthalocyaninetetrasulfonyl chloride (ClSO2)4NcGaOH 4Hydroxygallium naphthalocyaninetetrasulfonic acid 2 (374 mg; 0.334 mmol) from Example 1 was suspended in thionyl chloride (3 mL) containing a couple of drops of DMF. The reaction mixture was heated at 60-70° C. (bath) for 2 h under a slow stream of nitrogen, after which time the mixture became homogeneous and dark green in colour. After cooling to room temperature the resulting solution was diluted with chloroform (5 mL) and ether (50 mL) to precipitate the product. The supernatant liquid was decanted and the solid was suspended in ether (50 mL) and filtered off, washing with ether (3×10 mL). After drying under high vacuum the sulfonyl chloride 4 was obtained as a black solid (360 mg; 90%), that was insoluble in water, λmax (DMSO) 803 nm.

0113] The selectivity of the anti-inflammatory effect is preferably achieved through the control of the counterion(s), if any, present on the sulphonyl groups or present on the multiple sulphonyl and carboxylic groups and the nature of the sulphonyl group. Generally speaking, it is believed that selection of, say, sodium counterions on --SO3- groups (i.e. a sulpho group in salt form) will favour concentration of sodium salts (e.g. sodium chloride) in the wound bed, whereas selection of, say, potassium counterions on --SO3- groups will favour concentration of potassium salts (e.g. potassium chloride) in the wound bed whereas selection of, say, calcium counterions on --SO3- groups will favour concentration of calcium salts (e.g. calcium chloride) in the wound bed. For example, we believe that it will be advantageous for the molar ratio of sodium ions to potassium ions associated in the hydrogel composition (or sodium ions to other more weakly hydrated cations according to the Hofmeister series of ...

BMS-833923, also known as XL-139, is an orally bioavailable small-molecule SMO (Smoothened) inhibitor with potential antineoplastic activity. SMO antagonist BMS-833923 inhibits the sonic hedgehog (SHH) pathway protein SMO, which may result in a suppression of the SHH signaling pathway. SMO is a G-protein coupled receptor that lies just downstream of the SHH ligand cell surface receptor Patched-1 in the SHH pathway; in the absence of ligand Patched-1 inhibits SMO and ligand binding to Patched-1 results in increased levels of SMO. The SHH signaling pathway plays an important role in cellular growth, differentiation and repair; constitutive activation of this pathway is associated with uncontrolled cellular proliferation and has been observed in a variety of cancers
