Here we report for the first time a submolecularly resolved scanning tunneling microscopy (STM) study at the solid/liquid interface of the in situ reversible interconversion between two isomers of a diarylethene photoswitch, i.e., open and closed form, self-assembled on a graphite surface. Prolonged irradiation with UV light led to the in situ irreversible formation of another isomer as byproduct of the reaction, which due to its preferential physisorption accumulates at the surface. By making use of a simple yet powerful thermodn. simulation, physicochem. we provide a quant. description for the observed surface-induced selection of one isomeric form.

Barman, Siti published the artcileNMR, surface tension and conductance study to investigate host-guest inclusion complexes of three sequential ionic liquids with β-cyclodextrin in aqueous media, Quality Control of 23616-79-7, the publication is Chemical Physics Letters (2016), 43-50, database is CAplus.

Host-guest inclusion complexes of 3 sequential cationic room temperature surface active ionic liquids, benzyltrialkylammonium chloride [(C₆H₅CH₂)N(C_nH_2n+1)₃Cl; where n = 1, 2, 4] with β-cyclodextrin in aqueous media have been studied using surface tension, conductance and NMR spectroscopy. All the studies suggested that the hydrophobic benzyl group of ionic liquids is encapsulated inside into the cavity of β-cyclodextrin and played a crucial role in supporting the formation of inclusion complexes. The variation of the thermodn. parameters with guest size, shape is used to draw inferences about contributions to the overall binding by the driving forces, viz., hydrophobic effect, steric hindrance, van der Waal force, and electrostatic force.

Herscovici, Jean published the artcileSynthesis of spiroepoxynucleosides, Recommanded Product: trimethyloxosulphonium chloride, the publication is Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) (1986), 1297-301, database is CAplus.

The first syntheses of spiroepoxyhexopyranosylpurines and -pyrimidines, e.g., I (R = theophyllinyl, thyminyl), are reported. The spiro epoxy group was introduced at C-2′ by treatment of 2′-keto-β-L-nucleosides with dimethylsulfoxonium methylide. Addition of the sulfur ylide generated from Me₃SOCl and NaH afforded β-L–talo– and β-L–galacto-spironucleosides. Interestingly, when trimethylsulfoxonium chloride was activated with BuLi, an inversion took place at C-1′ leading exclusively to an α-L–galacto-spironucleoside.

Kanmani published the artcileSynthesis, spectral, electrochemical and catalytic properties of Cu(II), Ni(II) and Co(II) complexes containing N,O donors, Computed Properties of 19652-33-6, the publication is Journal of Molecular Catalysis A: Chemical (2009), 303(1-2), 52-59, database is CAplus.

Metal(II) chelates of Schiff bases derived from the condensation of multi-substituted aniline with salicylaldehyde derivatives were prepared Product structures were determined by NMR, IR, EPR, magnetic and cyclic voltammetry measurements. The complexes are of the type M(X-DPMP)₂ [(M = Cu(II), Ni(II) or Co(II)), DPMP = 2-[[(2,6-diisopropylphenyl)imino]methyl]phenol, X = Br, Cl, I, BrCl]. These Schiff bases behave as monobasic bidentate ligands in their complexes. The spectral data indicate that the ligand coordinates through a phenolic oxygen and the azomethine nitrogen atoms. The observed A _|| values in the Cu(II) complexes indicate a tetrahedrally distorted square planar structure. The cyclic voltammetric redox potential of copper(II) and nickel(II) complexes suggest the existence of irreversible pairs in acetonitrile. Cu(Br-DPMP)₂ was found to be an efficient catalyst for the cyanosilylation of aldehydes under mild conditions.

Munkuev, Aldar A. published the artcileAdamantane-Monoterpenoid Conjugates Linked via Heterocyclic Linkers Enhance the Cytotoxic Effect of Topotecan, Formula: C10H15ClO3S, the publication is Molecules (2022), 27(11), 3374, database is CAplus and MEDLINE.

Inhibiting tyrosyl-DNA phosphodiesterase 1 (TDP1) is a promising strategy for increasing the effectiveness of existing antitumor therapy since it can remove the DNA lesions caused by anticancer drugs, which form covalent complexes with topoisomerase 1 (TOP1). Here, new adamantane-monoterpene conjugates with a 1,2,4-triazole or 1,3,4-thiadiazole linker core were synthesized, where (+)-and (-)-campholenic and (+)-camphor derivatives were used as monoterpene fragments. The campholenic derivatives showed activity against TDP1 at a low micromolar range with IC₅₀ ~5-6μM, whereas camphor-containing compounds were ineffective. Surprisingly, all the compounds synthesized demonstrated a clear synergy with topotecan, a TOP1 poison, regardless of their ability to inhibit TDP1. These findings imply that different pathways of enhancing topotecan toxicity other than the inhibition of TDP1 can be realized.

Kleimenov, B. V. published the artcileMechanism of the action of organic substances containing a trichloromethyl group in reducing friction under high-load conditions, Related Products of chlorides-buliding-blocks, the publication is Teoriya Smazochnogo Deistviya i Novye Materialy (1965), 48-52, database is CAplus.

Acids containing the CCl₃ group have high antiwear properties. These properties decrease considerably after replacing the H of the acid by an aliphatic radical or a base. In the presence of HOAc, the critical load is 96 kg., while with Cl₃CCO₂H, it is ≤300 kg. When CCl₃P(O)(OBu)₂ is applied, the critical load is lower than if a simple acid is used. Heating of CCl₃P(O)(OBu)₂ at 160-80° results in elimination of the hydrocarbon radical with formation of butylene, CCl₃P(O)(OBu)OH, and CCl₃P(O)(OH)₂. Heating of CCl₃P(O)(OH)₂ to 325° gives HCl and CO. No free Cl is formed. Two varieties of interaction between the additive and the metal surface occur: chemisorptive saturation of free bonds of the surface atoms of the metal without destroying the crystal lattice linkage, or full chem. linkage of the reagent with the metal atoms which may destroy the crystal lattice linkage. Thus, 2 antagonistic actions occur: the formation of a chem. modified surface and its destruction. The decrease of wear and seizing is achieved by the acceleration of the chem. modification. The presence of the CCl₃ group polarizes the additive mol. and increases the viscosity of chemisorption onto the surface of the metal. At high temperature of the friction zone, the additive undergoes thermal decomposition and formation of (trichloromethyl)phosphonic acids. These acids interact with the metal to form salts and modify the metallic surface. The interaction is an ionic oxidation-reduction and can be represented by the equation Fe + 2H⁺ = Fe⁺⁺ + 2H. The addition of the CCl₃ group increases the H⁺ concentration in the friction zone, which is one of the main reasons for the antiwear properties of compounds containing the CCl₃ group.
