Quality Control of 1,10-Phenanthroline. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 1,10-Phenanthroline, is researched, Molecular C12H8N2, CAS is 66-71-7, about Application of molybdenum disulfide nanosheets adsorbent for simultaneous preconcentration and determination of Cd(II), Pb(II), Zn(II) and Ni(II) in water samples.

In this research, the two-dimensional molybdenum disulfide nanosheets (MoS2-NSH) were synthesized and successfully used as an effective adsorbent for preconcentration of trace amounts of four heavy metal ions (including, Cd, Ni, Zn and Pb) before measurements with flame at. absorption spectrometry (FAAS). The prepared MoS2-NSH was characterized by Fourier transform-IR spectroscopy (FT-IR), SEM (SEM), Energy-Dispersive X-Ray Spectroscopy (EDS) and transmission electron microscopy (TEM). The main anal. parameters which can influence the quant. recoveries of target analyte ions; such as solution pH, eluent type and its volume, adsorbent dosage and initial sample volume, were investigated. Under the optimized conditions, the recoveries of metal ions were > 90% at pH of 5.5, and the limits of detection values were found to be 0.37, 0.97, 0.76 and 1.09μg L-1 for Cd(II), Ni(II), Zn(II) and Pb(II), resp. The relative standard deviations (% RSD) for target ions were less than 5.3%. In addition, based on the exptl. data, the kinetics studies and adsorption isotherms were evaluated and the results showed that the pseudo-second-order kinetic model and Langmuir adsorption isotherm were well-fitted with the ions adsorption data. The suggested procedure has been successfully utilized in the anal. of some environmental water samples with satisfactory recoveries in the range of 93.6 to 107.2%.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 1,10-Phenanthroline, is researched, Molecular C12H8N2, CAS is 66-71-7, about Molecular precursor route for the phase selective synthesis of α-MnS or metastable γ-MnS nanomaterials for magnetic studies and deposition of thin films by AACVD, the main research direction is manganese sulfide nanomaterial thin film chem vapor deposition.Recommanded Product: 1,10-Phenanthroline.

Heterocyclic dithiocarbamate complex of manganese and the adducts of the complex with 1,10-phenanthroline and 2,2-bipyridyl resp. were synthesized and characterized. The complexes were used as single-source precursors for the preparation of MnS nanoparticles via thermolysis in oleylamine (OLA) and dodecanethiol (DT). The optimized reaction parameters have resulted in the formation of α-MnS and γ-MnS nanoparticles depending on the dispersion medium and the nature of the precursor. The same precursors were also used for the deposition of MnS thin films by the aerosol-assisted chem. vapor deposition (AACVD) method in varying solvents and temperatures The morphol. and phase of the synthesized nanoparticles were shown to be affected by the precursor type and the nature of the surfactants. SEM images showed that the morphol. of the deposited thin films is affected by precursor type and the deposition temperature Worm-like to rod-like films were observed on TEM images at 350 °C, which changes to spherical or cubic films at 450 °C. Magnetic measurements at room temperature showed the α-MnS and γ-MnS nanoparticles in paramagnetic states due to Mn2+ moments. The susceptibility for the γ-phase is at least double that of the α-phase. Finite and small hysteretic effects in low fields are indicative of small ordered antiferromagnetic phases due to neg. exchange interaction between Mn2+ ions.

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, Article, Research Support, Non-U.S. Gov’t, Journal of Medicinal Chemistry called New Generation of Selective Androgen Receptor Degraders: Our Initial Design, Synthesis, and Biological Evaluation of New Compounds with Enzalutamide-Resistant Prostate Cancer Activity, Author is Hwang, Dong-Jin; He, Yali; Ponnusamy, Suriyan; Mohler, Michael L.; Thiyagarajan, Thirumagal; McEwan, Iain J.; Narayanan, Ramesh; Miller, Duane D., which mentions a compound: 2343-22-8, SMILESS is FC1=CC2=C(NCC2)C=C1, Molecular C8H8FN, Reference of 5-Fluoroindoline.

In our effort to find small-mol. treatments of advanced prostate cancers (PCs), a novel series of indolyl and indolinyl propanamides (series II and III) were discovered as selective androgen receptor degraders (SARDs). Initial studies of androgen receptor (AR) antagonist (1) and agonist (2) propanamides yielded a tertiary aniline (3) with novel SARD activity but poor metabolic stability. Cyclization to II and III produced submicromolar AR antagonism and protein degradation selective to AR and AR splice variant (AR SV). II and III maintained potency against enzalutamide-resistant (Enz-R) mutant ARs and PC cells and were efficacious in Enz-R xenografts, suggesting their potential to treat advanced PCs. Design, synthesis, and biol. activity of novel SARDs that could potentially be used for the treatment of a wide spectrum of PCs including castration-resistant, Enz-R, and/or AR SV-dependent advanced PCs that are often untreatable with known hormone therapies are discussed.

A series of new platinum(II) mixed ligand complexes of diethyldithiocarbamate (Et2DT) and phosphine or amine ligands of the type [Pt(Et2DT)2(diphosphine)] (3-6), [Pt(Et2DT)2(diamine)](7-8), [Pt(Et2DT)2(PPh3)2] (9) and [Pt(Et2DT)2(SPPh3)2](10) have been prepared in good yield and fully characterized by elemental anal., conductivity measurements and spectroscopic data (i.r., 1H, 31P-{1H} nmr). Our interest in these types of complexes are based on the fact that these complexes are known for their promising biol. activity, and could possess interesting coordination modes, which are poorly represented in the literature. Therefore, the prepared complexes were tested for their anti-bacterial against three types of pathogenic bacteria namely S. aureus, E. coli, and p. aeruginosa. In addition, four of the prepared complexes were screened for their anti-cancer activity against lung cancer cell lines, and that the [Pt(Et2DT)2(bipy)] was significantly more potent with IC50 value is 1.0 ± 0.2μM, but the [Pt(Et2DT)2(dppf)] was practically inactive in the selected dose range with IC50 value is 32.0 ± 3.0μM.

The enantioface-differentiating ability (e.d.a.) of tartaric acid (I) modified reduced Ni catalysts, examined in the reduction of AcCH2CO2Me to MeCH(OH)CH2CO2Me, was strongly affected by the type of NiO used for catalyst preparation and the preparative treatment. Acidic and high temperature modification or acid-treatment of reduced Ni (HNi) before I modification improved to e.d.a. as these treatments removed the amorphous, nonstereodifferentiating, parts of the HNi.
