Heterocyclic Building Blocks-benzodioxan

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1762-34-1, is researched, Molecular C12H12N2, about Molecular engineering towards tunable morphology of metal-organic complex microcrystals for efficient and multicolor electrochemiluminescence, the main research direction is mol engineering towards tunable morphol metal organic complex microcrystals; multicolor electrochemiluminescence.Recommanded Product: 1762-34-1.

Electrochemiluminescence (ECL) of crystalline materials has recently attracted increasing attention due to their unique characteristics and applications, such as crystallization-induced emission, active waveguiding, and biosensing. Tris(2,2′-bipyridine)ruthenium(II), [Ru(bpy)3]2+, a classical metal-organic complex for ECL studies, has been fully investigated in solution as well as its derivatives However, the dependence of ECL properties on the mol. structure and crystal morphol. of these complexes has not been illustrated, partially due to the difficulty in the controlled crystal growth. Here, we adopt a facile mol. engineering strategy to obtain microcrystals of [Ru(bpy)3]2+ derivatives with well-defined morphol. (rods, wires, or polyhedrons) and varied phosphorescence emission colors (yellow, orange, and red) by simply changing the position and number of Me substituents on the bipyridine ligands. The packing modes of mols. influenced by Me groups play a vital role in crystal growth based on attachment energy anal. The obtained microcrystals could act as ECL luminophores when modified on glassy carbon electrode surfaces. Those with one-dimensional (1D) morphol. generally show superior ECL efficiency and stability to three-dimensional (3D) shaped microcrystals. ECL biosensors made of stable 1D microcrystals show reliable and sensitive responses to hydroxyproline, demonstrating their capacity in recyclable detections. This work demonstrates the great potential of mol. engineering in controlling the morphol., emission colors, and ECL properties of mol. crystals, paving the way for the development of high-performance ECL biosensing and optoelectronic devices.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Organometallics called Group 6 Metal Complexes as Electrocatalysts of CO2 Reduction: Strong Substituent Control of the Reduction Path of [Mo(η3-allyl)(CO)2(x,x’-dimethyl-2,2′-bipyridine)(NCS)] (x = 4-6), Author is Taylor, James O.; Veenstra, Florentine L. P.; Chippindale, Ann M.; Calhorda, Maria Jose; Hartl, Frantisek, which mentions a compound: 1762-34-1, SMILESS is CC1=CN=C(C=C1)C1=NC=C(C)C=C1, Molecular C12H12N2, Formula: C12H12N2.

[Mo(η3-allyl)(CO)2(x,x’-dmbipy)(NCS)] (dmbipy = dimethyl-2,2′-bipyridine; x = 4-6) were synthesized and their electrochem. reduction studied using combined cyclic voltammetry (CV) and variable-temperature spectroelectrochem. (IR/UV-visible SEC) in THF and butyronitrile (PrCN), at Au and Pt electrodes. The exptl. results, strongly supported by d. functional theory (DFT) calculations, indicate that the general cathodic path of these Group 6 organometallic complexes is closely related to that of the intensively studied class of Mn tricarbonyl α-diimine complexes, which, themselves, have recently been identified as important smart materials for catalytic CO2 reduction The di-Me substitution on the 2,2′-bipyridine ligand backbone has presented new insights into this emerging class of catalysts. For the 1st time, the 2e- reduced 5-coordinate anions [Mo(η3-allyl)(CO)2(x,x’-dmbipy)]- were directly observed with IR spectroelectrochem. (IR SEC). The role of steric and electronic effects in determining the reduction-induced reactivity was also studied. For the 6,6′-dmbipy, the primary 1e- reduced radical anions exert unusual stability, radically changing the follow-up cathodic path. The 5-coordinate anion [Mo(η3-allyl)(CO)2(6,6′-dmbipy)]- remains stable at low temperature in strongly coordinating butyronitrile and does not undergo dimerization at elevated temperature, in sharp contrast to reactive [Mo(η3-allyl)(CO)2(4,4′-dmbipy)]- that tends to dimerize in a reaction with the parent complex. The complex with the 5,5′-dmbipy ligand combines both types of reactivity. Under aprotic conditions, the different properties of [Mo(η3-allyl)(CO)2(x,x’-dmbipy)]- are also reflected in their reactivity toward CO2. Preliminary CV and IR SEC results reveal differences in the strength of CO2 coordination at the free axial position. Catalytic waves attributed to the generation of the 5-coordinate anions were observed using CV, but only a modest catalytic performance toward the production of formate was demonstrated by IR SEC. For 6,6′-dmbipy, a stronger catalytic effect was observed for the Au cathode, compared to Pt.

Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1762-34-1) here.

Engineering synthetic materials that mimic the complex rhythmic oscillatory behavior of living cells is a fundamental challenge in science and technol. Up to now, the reported synthetic model system still cannot compete with nature in oscillatory modes and amplitudes. Presented here is a novel alternating copolymer vesicle that exhibits drastic and multimode shape oscillations in real time, which are controlled by polymer concentrations and driven by the Belousov-Zhabotinsky oscillatory reaction, including swelling/deswelling, twisting/detwisting, stretching/shrinking, fusion/fission, and multiple division. Some of them, especially the fission oscillation, have not been observed before. In addition, the oscillation magnitude with regard to diameter is much larger than that of previously reported self-oscillating vesicles. Such a self-oscillating vesicle transformer would extend the complexity and capacity of membrane deformations in synthetic systems, approaching those of natural cells.

Safety of 5,5′-Dimethyl-2,2′-bipyridine. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Ru(II)/N-N/PPh3 complexes as potential anticancer agents against MDA-MB-231 cancer cells (N-N = diimine or diamine). Author is Ribeiro, Gabriel H.; Colina-Vegas, Legna; Clavijo, Juan C. T.; Ellena, Javier; Cominetti, Marcia R.; Batista, Alzir A..

The rational design of anticancer agents that acts in specific biol. targets is one of the most effective strategies for developing chemotherapeutic agents. Aiming at obtaining new ruthenium(II) compounds with good cytotoxicity against tumor cells, a series of new complexes of general formula [RuCl(PPh3)(Hdpa)(N-N)]Cl [PPh3 = triphenylphosphine, N-N = 2,2′-dipyridylamine (Hdpa) (1), 1,2-diaminoethane (en) (2), 2,2′-bipyridine (bipy) (3), 5,5′-dimethyl-2,2′-bipyridine (dmbipy) (4), 1,10-phenanthroline (phen) (5) and 4,7-diphenyl-1,10-phenanthroline (dphphen) (6)] were synthesized. The complexes were characterized by elemental anal. and spectroscopic techniques (IR, UV/Visible, and 1D and 2D NMR) and three of their x-ray structures were determined: [RuCl(PPh3)(Hdpa)2]Cl, [RuCl(PPh3)(Hdpa)(en)]Cl and [RuCl(PPh3)(Hdpa)(dmbipy)]Cl. All the complexes are more cytotoxic against the cancer cell line than against the non-tumor cell line, highlighting complexes 1 and 5, which have an index selectivity of 18 and 15, resp. The binding constants of compounds 1-6 with human serum albumin (HSA) were determined by tryptophan fluorescence quenching, indicating moderate to strong interactions. The binding mode of the complexes to calf thymus (CT) DNA was explored by several techniques, which reveal that only the dphphen compound 6 causes distortions in the secondary and tertiary structures of DNA. The nature of the N-N co-ligand and the presence of the PPh3 and Hdpa ligands are features that can influence the binding affinity of the complexes by the biomols. and in the cytotoxic activity of the complexes. Overall, the complexes with diimine co-ligand are much more cytotoxic than compound 2 with the aliphatic diamine.

The binuclear iron(III) complex (1), namely, {[Fe(5,5′-dmbpy)2(OH2)]2(O)}(NO3)4 with a distorted octahedral coordination, formed by four nitrogen and two oxygen atoms, was previously reported by our team. In this study the DNA-binding and cytotoxicity evaluation for target complex were studied. The results indicated strong cytotoxicity activity against A549 cells comparable to cisplatin values. The binding interaction between complex 1 and FS-DNA was investigated by UV-Vis, fluorescence spectroscopy, and gel electrophoresis at physiol. pH (7.2). The DNA binding investigation has shown groove binding interactions with complex 1, therefore the hydrogen binding plays an important role in the interaction of DNA with complex 1. The calculated thermodn. parameters (ΔH°, ΔS° and ΔG°) show that hydrogen bonding and Vander-Waals forces have an important function in Fe(III) complex-DNA interaction. Moreover, DNA cleavage was studied using agarose gel electrophoresis. Viscosity measurements illustrated that relative viscosity of DNA was unchanged with the adding concentrations of Fe(III) complex. Mol. docking simulation results confirmed the spectroscopic and viscosity titration outcomes.
