Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1127-45-3, is researched, SMILESS is OC1=CC=CC2=CC=C[N+]([O-])=C12, Molecular C9H7NO2Journal, Article, Dalton Transactions called High anticancer activity and apoptosis- and autophagy-inducing properties of novel lanthanide(III) complexes bearing 8-hydroxyquinoline-N-oxide and 1,10-phenanthroline, Author is Yang, Yan; Zhou, Zhen; Wei, Zu-Zhuang; Qin, Qi-Pin; Yang, Lin; Liang, Hong, the main research direction is lanthanide hydroxyquinolinenoxide phenanthroline anticancer lung adenocarcinoma.Computed Properties of C9H7NO2.

In the quest for rare earth metal complexes with enhanced cancer chemotherapeutic properties, the discovery of seven lanthanide(III) complexes bearing 8-hydroxyquinoline-N-oxide (NQ) and 1,10-phenanthroline (phen) ligands as potential anticancer drugs is described. Complexes [SmIII(NQ)(phen)(H2O)Cl2] , [EuII(NQ)(phen)(H2O)Cl2] , [GdIII(NQ)(phen)(H2O)Cl2] , [DyIII(NQ)(phen)(H2O)Cl2] , [HoIII(NQ)(phen)(H2O)Cl2] , [ErIII(NQ)(phen)(H2O)Cl2] , and [YbIII(NQ)(phen)(H2O)Cl2] exhibit high antiproliferative activity against cisplatin-resistant A549/DDP cells (IC50 = 0.025-0.097 μM) and low toxicity to normal HL-7702 cells. Moreover, complex [SmIII(NQ)(phen)(H2O)Cl2], and to a lesser extent [YbIII(NQ)(phen)(H2O)Cl2], can upregulate the expression of LC3 and Beclin1 and downregulate p62 to induce apoptosis in cisplatin-resistant A549/DDP cell lines, which is related to the cell autophagy-inducing properties of [SmIII(NQ)(phen)(H2O)Cl2] and [YbIII(NQ)(phen)(H2O)Cl2]. Furthermore, in vivo assays suggest that [SmIII(NQ)(phen)(H2O)Cl2] significantly inhibits A549/DDP xenograft tumor growth (56.5%). These results indicate that lanthanide(III) complex [SmIII(NQ)(phen)(H2O)Cl2] is a promising candidate as an anticancer drug against cisplatin-resistant A549/DDP cells.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Photoelectron spectra induced by x-rays of above 600 nonmetallic compounds containing 77 elements, published in 1972, which mentions a compound: 13940-83-5, Name is Nickel(ii)fluoridetetrahydrate, Molecular F2H8NiO4, Computed Properties of F2H8NiO4.

The photoelectron spectra induced by Al (1486.6 eV) or Mg (1253.6 eV) x-ray excitation of >600 compounds indicate that the chem. shift (dI) of the ionization energy (I) of the inner shells is not only dependent on the oxidation state of a given element, but also on the ligands. Even for a fixed oxidation state, dI was 2-8 eV in a comparative study of all elements which are neither noble gases nor strongly radioactive. However, this conclusion is, to some extent, modified by reproducible pos. potentials on nonconducting samples which were measured at 1-4V in typical cases and compared with the theory for almost ionic cubic crystals and with experiments with mixtures of nonconducting powd. MgF2, BaSO4, and ThF4 and metals such as Au, Tl2O3, and CuS. The widths and highly varying intensities of photoelectron signals are theor. discussed. The d and f shells of transition and post-transition group atoms give relatively intense signals even for I 8-30 eV since the 1486.6-eV photons most readily ionize shells with small average radii. Interesting relations can be established with electron transfer spectra and optical electronegativities. Special satellites occur in Cu(II), La(III) and other lanthanide compounds The adaptation of the electronic d. of the neighbor atoms in the ionized system contribute to dI which cannot be explained exclusively on the basis of fractional at. charges and the Madelung potential.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 1-(Bromomethyl)-4-ethylbenzene, is researched, Molecular C9H11Br, CAS is 57825-30-6, about Design, synthesis and evaluation of 3-(imidazol-1-ylmethyl)indoles as antileishmanial agents. Part II, the main research direction is benzylimidazolylmethylindole preparation antileishmanial agent; indole benzylimidazolylmethyl preparation antileishmanial agent.Formula: C9H11Br.

A new series of 1-benzyl-3-(imidazol-1-ylmethyl)indoles were synthesized according to a previous 3D-QSAR predictive model and assayed for their antiparasitic activity upon Leishmania mexicana promastigotes. The biol. results obtained for these twelve mols. showed an IC50 ranging from 2.3 to 32 μM and mainly illustrated the importance of the hydrophobic parameter in the para-position of the benzyl group. In order to improve the activities of these compounds and to check the potential influence of the electronic parameter on this particular position, a Craig diagram was used to select original electro-donating and lipophilic substituents. Synthesis and biol. evaluation of ten new compounds (IC50 between 2.5 and 5.4 μM) confirmed that only the hydrophobic field is essential for a high level of activity.

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, Chemical Science called An N-heterocyclic carbene ligand promotes highly selective alkyne semihydrogenation with copper nanoparticles supported on passivated silica, Author is Kaeffer, Nicolas; Liu, Hsueh-Ju; Lo, Hung-Kun; Fedorov, Alexey; Coperet, Christophe, which mentions a compound: 32717-95-6, SMILESS is C12=C(CCC3=C4CC2)[Cu+]1534[Cl-][Cu+]678(C9=C6CCC7=C8CC9)[Cl-]5, Molecular C16H16Cl2Cu2, Name: Chloro(1,5-cyclooctadiene)copper(I) dimer.

A surface organometallic route that generates copper nanoparticles (NPs) on a silica support while simultaneously passivating the silica surface with trimethylsiloxy groups is reported. The material was active for the catalytic semihydrogenation of phenylalkyl, dialkyl and diaryl alkynes and displayed high chemo- and stereoselectivity at full alkyne conversion to corresponding (Z)-olefins in the presence of an N-heterocyclic carbene (NHC) ligand. Solid-state NMR spectroscopy using the NHC ligand 13C-labeled at the carbenic carbon revealed a genuine coordination of the carbene to Cu NPs. The presence of distinct Cu surface environments and the coordination of the NHC to specific Cu sites likely accounted for the increased selectivity.
