Application of 1271-48-3, Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 1271-48-3, Name is 1,1′-Ferrocenedicarboxaldehyde, molecular weight is 242.0516. In an Article，once mentioned of 1271-48-3

Synthesis, structure determination and in vitro antiproliferative assay of a series of novel ferrocenenyl hydrazones containing 4-halopyridazin-3(2H)-one fragment(s) and three representative N-arylsubstituted (Sp)-ferroceno[d] pyridazinones are presented. The model compounds can be considered as different assemblies of the potential binding sites capable of establishing interactions including hydrogen bonds and pi-pi interactions with the relevant residues of biomolecules. Their in vitro antiproliferative effect was investigated against four tumorous cell lines by the 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT)-assay. Our data indicate that bis-hydrazone of 1,1?-diformylferrocene carrying N-benzyl substituents and a chloropyridazinyl-substituted ferroceno[d]pyridazinone display significant activity on each cell lines investigated. The efficiency of the latter drug candidate and one N-benzyl mono-hydrazone on A2870 cell line is comparable to that of cisplatin. The constitution and relative configuration of the model compounds were established by 1H, 13C and 15N NMR methods. The structures of a mono- and bis-ferrocenylhydrazone containing 4-bromopyridazinone unit(s) were confirmed by single crystal X-ray diffraction.

Reaction of l,l’,3,3′-tetra(tert-amyl)benzobis(imidazolylidene) (1) with 2 equiv of FcN3 or FcNCS afforded bisadducts [(FcN3) 2(1)] (2) or [(FcNCS)2(1)] (3), respectively (Fc = ferrocene). To the best of our knowledge, these represent the first examples of complexes comprising metals indirectly connected to the carbene atoms of N-heterocyclic carbenes (NHCs) via their ligand sets. Cyclic and differential pulse voltammetry indicated that bis(NHC) 1 facilitated significant electronic coupling between ferrocene centers in 2 (DeltaE = 140 mV), but not in 3. We believe the different degrees of electronic interaction are due to geometric factors: the triazene linker in 2 is nearly coplanar with the bis(NHC) scaffold, whereas the isothiocyanate linker is orthogonal, as determined by X-ray crystallography. Employing this “indirect connection” strategy should enable tuning of metalmetal interactions by simple alteration the organic linker between NHC and MLn fragments rather than complete redesign thereof. Given that NHC-reactive azide or isothiocyanate groups can be incorporated into both organic and inorganic compounds, this approach is envisioned to facilitate access to otherwise inaccessible catalysts and materials.

A central challenge of sensor technology is that the sensitivity of analytical detection is required to reach a single analyte entity level, whether it is a molecule, a cell or a nanoparticle. The emergence of nano-impact electrochemistry (NIE) allows in situ detection of single analyte entity one at a time with simplicity, fast response and high throughput. NIE method was originally designed to characterize physical and chemical properties of the corresponding single nanoparticles, and has been later extended into the field of bio-analysis, enabling better understanding of biological heterogeneity and providing new route for developing new diagnostic devices for quantifying biological analytes. A wide range of biological species including DNA, RNA, enzymes, bacteria, vesicles and cells has been already studied using NIE method so far. In this review, we first summarize the basic principles of NIE for bio-analyte detection and then elaborate NIE based bio-analysis categorized by analyte types. Finally, we give an outlook on the future prospects of this field.

SDS of cas: 1273-86-5, Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a reaction from occurring.

Thymol, a potent agent for microbial, fungal, and bacterial disease, has low aqueous solubility and it is genotoxic, i.e., is capable of damaging deoxyribonucleic acid (DNA). This possible problem of DNA toxicity needs to be solved to allow the use of different doses of thymol. This study characterized the inclusion compound containing thymol and beta-cyclodextrin (beta-CD) by measuring the interaction between these two components and the ability of thymol to bind DNA in its free and beta-CD complexed form. The encapsulation approach using beta-CD is particularly useful when controlled target release is desired, and a compound is insoluble, unstable, or genotoxic. The interaction between thymol and DNA has been studied using electrochemical quartz crystal microbalance (EQCM), atomic force microscopy (AFM), and differential pulse voltammetry (DPV). The characterization of the inclusion complex of thymol and beta-CD was analyzed by UV-vis spectrophotometry, cyclic voltammetry, and scanning electrochemical microscopy (SECM). Based on the free beta-CD by spectrophotometry method, the association constant of thymol with the beta-CD was estimated to be 2.8 × 104 L mol?1. The AFM images revealed that in the presence of small concentrations of thymol, the dsDNA molecules appeared less knotted and bent on the mica surface, showing significant damage to DNA. The SECM and voltammetry results both demonstrated that the interaction of thymol-beta-CD complex was smaller than the free compound showing that the encapsulation process may be an advantage leading to a reduction of toxic effects and increase of the bioavailability of the drug.

The iron(III) protoporphyrin IX complex with imidazole, a biologically relevant ligand, occupying an axial position, has been studied by infrared multiple photon dissociation (IRMPD) spectroscopy. The complex has been delivered in gas-phase by electrospray ionization (ESI), mass selected in an ion trap, and assayed by IRMPD spectroscopy in two complementary frequency regions. The fingerprint range (900-1900 cm-1) has been scanned using the Orsay free-electron laser beamline (CLIO), while the X-H (X = C,N,O) stretching region (3000-3600 cm-1) has been inspected using a tabletop IR optical parametric oscillator/amplifier (OPO/OPA) laser source. DFT calculations have been performed to obtain a comprehensive pattern of the various potential conformers yielding optimized geometries, relative thermodynamic parameters, and respective IR spectra. The comparison between the IR spectra for representative conformers and the experimental IRMPD features suggests the coexistence of two families of conformers involving different degrees of folding and hydrogen bonding between the two propionic acid functionalities on the periphery of the protoporphyrin IX macrocycle in a ratio depending on environmental conditions such as ESI solvent and temperature. The observed conformational variability of the porphyrin substituents in the naked heme-imidazole complex is consistent with the fine-tuning of the reactivity properties of this important prosthetic group by the specific surroundings in the protein core.

We report the synthesis, characterization, and cytotoxic and antimalarial activity of ferrocene-indole hybrids 8-14. The 2-phenylindole scaffold was chosen because of its potent antimitotic activity and ferrocene was chosen following the development of ferrocifens, ferrocene derivatives of tamoxifen, which are prototypes of a new family of organometallic anti-estrogens. Ferrocene-indole hybrids 8-14 and their corresponding organic analogues 1-7 showed only moderate antimalarial activities, while ferrocene-indole hybrids 11 and 12 showed excellent in vitro activities against the A549 human carcinoma cell line, with IC50 values of 5 and 7 muM respectively. These ferrocene-indole hybrids were up to 25-fold more potent as cytotoxic agents than their purely organic analogues.
