In this work, a sensitive, universal and reusable electrochemical biosensor based on stannic oxide nanocorals-graphene hybrids (SnO2 NCs-Gr) is developed for target DNA detection by using two kinds of DNA enzymes for signal amplification through an autonomous cascade DNA duplication strategy. A hairpin probe is designed composing of a projecting part at the 3?-end as identification sequence for target, a recognition site for nicking endonuclease, and an 18-carbon shim to stop polymerization process. The designed DNA duplication?incision?replacement process is handled by KF polymerase and endonuclease, then combining with gold nanoparticles as signal carrier for further signal amplification. In the detection system, the electrochemical?chemical?chemical procedure, which uses ferrocene methanol, tris(2-carboxyethyl)phosphine and L-ascorbic acid 2-phosphate as oxidoreduction neurogen, deoxidizer and zymolyte, separately, is applied to amplify detection signal. Benefiting from the multiple signal amplification mechanism, the proposed sensor reveals a good linear connection between the peak current and logarithm of analyte concentration in range of 0.0001?1 × 10?11 mol L?1 with a detection limit of 1.25 × 10?17 mol L?1 (S/N=3). This assay also opens one promising strategy for ultrasensitive determination of other biological molecules for bioanalysis and biomedicine diagnostics.

To date, there is an urgent need for cancer treatment to improve in many ways in order to successfully cure all cancers. Retinoic acid (RA) is a promising anti-cancer drug through influencing cancer stem cells (CSCs). Taxol is a chemotherapy drug for many cancers. To increase the anti-cancer effects of RA and taxol, we created a novel RA nanoparticle, FCRAN, which has the ability of carrying a second anti-cancer drug, taxol, using nanotechnological methods. The results of this study demonstrated that this RA nanoparticle was water-soluble and retained the same effects as RA on cancer cells, such as inhibiting the proliferation of CSCs, inducing the differentiation of CSCs, and enhancing the sensitivity of CSCs to chemotherapeutic drugs. In addition, this RA nanoparticle can be used to carry a second anticancer drug, taxol, to become FCRAN/T and synergistically enhance the anti-cancer effects of both drugs in vivo. Interestingly, the FCRAN/T is a targetable anti-cancer nanoparticle in the presence of higher levels of glutathione (GSH) in cancer cells. Our results demonstrate that our novel synthesized nanoparticles not only retain the RA functions, but can also carry a second anticancer drug to play a synergistic anticancer role with good water solubility, in particular FCRAN/T can target cancer cells. Therefore, our novel synthesized targetable anti-cancer nanoparticles have a better application prospect than that of RA or taxol alone.

A solvent free synthetic method using rice husk ash (RHA) as solid support has been designed for selective functionalization and preparation of novel 1,1?- unsymmetrically bi-functionalized ferrocenyl compounds. The selectively functionalized intermediate compound, Ferrocenyl-1-acetyl-1?-thiosemicarbazone, has been structurally characterized using single crystal X-ray diffraction technique which revealed distinct inter-molecular hydrogen bonding interactions across the thiosemicarbazone chains. Cytotoxic evaluation of five different unsymmetrically bi-functionalized thiosemicarbazone – hydrazone compounds showed potent activity against human leukemia (THP-1) cell line. The unsymmetrical ferrocenyl compounds also showed strong BSA and DNA binding interactions and reversible redox properties.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states. SDS of cas: 1273-94-5, you can also check out more blogs about1273-94-5

An efficient system for the catalytic redox isomerization of the allylic alcohol 1-octen-3-ol to 3-octanone is presented. The homogeneous ruthenium(II) catalyst contains a monodentate phosphane ligand with a ferrocene moiety in the backbone and provides 3-octanone in quantitative yields. The activity is increased by nearly 90 % with respect to the corresponding triphenyl phosphane ruthenium(II) complex. By grafting the catalyst at the surface of a dendrimer, the catalytic activity is further increased. By introducing different spacers between ferrocene and phosphorus, the influence on the electronic properties of the complexes is shown by evaluating the electrochemical behavior of the compounds.

An ultrasensitive sandwich-type electrochemical biosensor for microRNA (miRNA) detection is developed based on magnesium oxide (MgO) nanoflower and graphene oxide?gold nanoparticles (GO?AuNPs) hybrids coupling with electrochemical?chemical?chemical (ECC) detection system. In this bioassay system, MgO nanoflowers and AuNPs are modified on electrode to act as sensing platform. The thiolated capture probe is then self-assembled onto AuNPs/MgO substrate via formation of Au-S bonds. Subsequently, a biotinylated DNA signal probe is conjugated to GO?AuNPs hybrids. When miRNA-21 is added, a sandwich complex is formed and a lot of signal indicators streptavidin-conjugated alkaline phosphatases (SA-ALP) are immobilized upon electrode by the specific reaction between avidin and biotin. Finally, ECC reaction is performed in the system to improve detection signal. The proposed sandwich-type assay benefits from advantages of sandwich-type structure for enhanced sensitivity and specificity, MgO nanoflowers/AuNPs as sensing platform and GO?AuNPs hybrids as signal carriers for signal amplification, and ECC as a sensitive detection system for low detection limit. This biosensor exhibits a good dynamic ranging from 0.1 to 100 fM and a low detection limit of 50 aM (S/N = 3) toward target miRNA-21.

Two types of transformations (the metal complex protonation and oxidation) have been revealed in the ferrocenylmethanol??2?2??? system (HX = HClO4, CF3COOH) by means of electronic spectroscopy. The efficiency of protonation has been determined from the intensity of the FcCH2 + carbocation absorption band (lambdamax = 600 nm); it depends on the acid strength and relative concentration as well as the solvent nature. Kinetics of ferrocenylmethanol oxidation in dioxane has been studied in the presence of trifluoroacetic acid. Two alternative reaction mechanisms have been proposed, differing in the coordination type of the reagents.

A chromotropic ferrocenyl chalcone with two pyrenyl groups (Fc-dPyr) is prepared and spectroscopically characterized. The X-ray structure analysis shows that the two pyrenyl groups are almost parallel to each other with a torsion angle of 5.57 and adopt a dimeric mode with a distance of 3.776 A? between them, ready to form an excimer. The solvatochromic fluorescence spectra indicate that the emission maxima observed in hydrogen-bonding donor (HBD) solvents (CHCl3, EtOH and MeOH) exhibit a strictly linear relationship with the normalized ETN value, while those in a non-HBD solvent (CH3CN) do not. The molecular chemosensor activity of Fc-dPyr is highly selective toward Fe(III) ions over Fe(II) ions. The fluorescence emission intensity of Fc-dPyr steeply decreases in the presence of Fe(III) ions as an oxidant, but not in the presence of Fe(II) ions.

In a patent，Which mentioned a new discovery about 16009-13-5

Despite the fact that multiple artemisinin-alkylated proteins in Plasmodium falciparum have been identified in recent studies, the alkylation mechanism and accurate binding site of artemisinin-protein interaction have remained elusive. Here, we report the chemical-probe-based enrichment of the artemisinin-binding peptide and characterization of the artemisinin-binding site of P. falciparum translationally controlled tumor protein (TCTP). A peptide fragment within the N-terminal region of TCTP was enriched and found to be alkylated by an artemisinin-derived probe. MS2 fragments showed that artemisinin could alkylate multiple amino acids from Phe12 to Tyr22 of TCTP, which was supported by labeling experiments upon site-directed mutagenesis and computational modeling studies. Taken together, the “capture-and-release” strategy affords consolidated advantages previously unavailable in artemisinin-protein binding site studies, and our results deepened the understanding of the mechanism of protein alkylation via heme-activated artemisinin.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states.
