Roy, Debayan published the artcileEvidence for Atropisomerism in Polycyclic γ-Butenolides: Synthesis, Scope, and Spectroscopic Studies, Application of ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, the publication is Chemistry – A European Journal (2021), 27(12), 4009-4015, database is CAplus and MEDLINE.

Design and development of a domino cyclative approach for the synthesis of new polycyclic γ-butenolides from β-aryl-Z-enoate propargylic alcs., through the interception of an intermediate of the Z-enoate-assisted Meyer-Schuster rearrangement, has been reported. A systematic NMR anal. of various derivatives of this class revealed and supported the potential atropisomerism associated with them. These mols. represent first examples of butenolide ring-based atropisomeric compounds in organic chem. The synthetic process involves a synchronous construction of both rings with concurrent creation of the potential stereogenic rotational axis.

Causey, Patrick W. published the artcileSynthesis, Characterization, and Assessment of Cytotoxic Properties of a Series of Titanocene Dichloride Derivatives, Recommanded Product: 2-Chloro-N,N-dimethylpropan-1-amine hydrochloride, the publication is Organometallics (2004), 23(19), 4486-4494, database is CAplus.

A series of 15 water-soluble titanocene dichloride derivatives containing alkylammonium groups pendant to one (monocationic complexes) or both (dicationic complexes) cyclopentadienyl rings has been synthesized and characterized. The in vitro cytotoxicities of this small library of potential anticancer drugs have been assessed against human lung cancer (H209, A549, H209/CP) and ovarian cancer (A2780, A2780/CP) cell lines, and the results are compared with the cytotoxicities of both cisplatin (cis-PtCl₂(NH₃)₂) and a clin. formulation of titanocene dichloride that is commonly used against cisplatin-resistant tumors. While none of the compounds exhibit potency greater than that of cisplatin, several are clearly superior to the clin. formulation. In particular dicationic complexes generally exhibit greater potency than do the corresponding monocationic analogs, and derivatives containing protonated piperidinyl rings exhibit greater potency than do compounds containing protonated 2-aminoethyl or 3-aminopropyl groups. Eight of the compounds, representing a wide range of potencies, were characterized crystallog. but no correlations between effectiveness and structures were obvious.

Reichelt, Andreas published the artcileSynthesis and structure-activity relationship of trisubstituted thiazoles as Cdc7 kinase inhibitors, Formula: C7H8BClO2, the publication is European Journal of Medicinal Chemistry (2014), 364-382, database is CAplus and MEDLINE.

The Cell division cycle 7 (Cdc7) protein kinase is essential for DNA replication and maintenance of genome stability. We systematically explored thiazole-based compounds as inhibitors of Cdc7 kinase activity in cancer cells. Our studies resulted in the identification of a potent, selective Cdc7 inhibitor (I) that decreased phosphorylation of the direct substrate MCM2 in vitro and in vivo, and inhibited DNA synthesis and cell viability in vitro.

Degorce, Sebastien L. published the artcileInvestigation of (E)-3-[4-(2-Oxo-3-aryl-chromen-4-yl)oxyphenyl]acrylic Acids as Oral Selective Estrogen Receptor Down-Regulators, HPLC of Formula: 209919-30-2, the publication is Journal of Medicinal Chemistry (2015), 58(8), 3522-3533, database is CAplus and MEDLINE.

A novel estrogen receptor down-regulator, 7-hydroxycoumarin (5, SS5020), has been reported with antitumor effects against chem. induced mammary tumors. Here, we report on our own investigation of 7-hydroxycoumarins as potential selective estrogen receptor down-regulators, which led us to the discovery of potent down-regulating antagonists, such as 33. Subsequent optimization and removal of the 7-hydroxy group led to coumarin 59, which had increased potency and improved rat bioavailability relative to SS5020.

Dill, Maren published the artcileEnhanced Accuracy of Single-Molecule Diffusion Measurements with a Photocleavable Energy-Transfer Dyad, SDS of cas: 42074-68-0, the publication is Angewandte Chemie, International Edition (2013), 52(47), 12435-12438, database is CAplus and MEDLINE.

We developed and photochem. characterized a photocleavable energy-transfer dyad and demonstrated its applicability for single-mol. microspectroscopy. After photocleavage, it allows for following the evolution of distances between both fragments from the nm to the pm length scale using single-mol. energy-transfer efficiencies and independent two-color tracking, resp. Observation of changes in the single-mol. energy-transfer efficiencies between both fragments enables the determination of low single-mol. diffusion coefficients and their distribution with high accuracy compared to single-mol. tracking. Future work will focus on exploiting our novel approach to measure slow diffusion in polymer systems and to extend it to other fluorophores and photolabile moieties.

Xu, Yisong published the artcileHydrosilylation of alkenes catalyzed by rhodium with polyethylene glycol-based ionic liquids as ligands, Product Details of C9H20Cl2Si, the publication is Journal of Organometallic Chemistry (2014), 59-63, database is CAplus.

A series of polyethylene glycol-functionalized imidazolium ionic liquids has been prepared and characterized. These ionic liquids have been successfully applied in the hydrosilylation of alkenes catalyzed by rhodium complexes. The effects of the length of the polyether chain, the amount of ionic liquid, and the reaction temperature on the catalytic performance of hydrosilylation have been investigated. Furthermore, the catalytic system has been tested for the hydrosilylation of different alkenes with triethoxysilane. The new catalytic system exhibits both excellent catalytic activity and selectivity under low-temperature conditions. The catalyst system could be recycled five times with slightly deactivation.

Zhao, Guofeng published the artcileDevelopment of a displacer-immobilized ligand docking scheme for displacer screening for protein displacement chromatography, Synthetic Route of 23616-79-7, the publication is Biochemical Engineering Journal (2011), 55(1), 32-42, database is CAplus.

Displacement chromatog. is a powerful technique for protein purification, but the availability of high-efficacy displacers has greatly limited its applications. In this work, a displacer-immobilized ligand docking scheme was developed for the prediction of displacer efficacy and displacer screening for displacement chromatog. of proteins. The structure of immobilized ligand was established by coupling a certain number of ligands to the 3D structure of agarose. A number of known cation, anion and hydrophobic displacers were docked to their resp. immobilized ligands to verify the effectiveness of the scheme, and the Spearman ranking correlation coefficients of all cases were over 0.5. The scheme was then used to screen displacers for hydrophobic charge induction chromatog. from over 1800 com. available compounds Column displacement experiments of several representative compounds showed that the identified displacers were efficacious in the displacement of single component and binary mixtures It is expected that the combination of the docking scheme with the existing techniques for displacer discovery/design would greatly facilitate the discovery of high-affinity displacers for protein purification

(E)-gem-Alkyl,aryl-disubstituted allyl carbonates can react with ketones under Pd catalysis using a com. available NHC ligand by suppressing the β-H elimination. Ketones with α-tertiary, β-quaternary carbon stereocenters were produced in high yields with high regio- and diastereoselectivities. Kinetic resolution of the reaction product via CBS reduction afforded the optically active ketone I as well as the alc. II with high enantioselectivity (S-factor = 35). The utility of the methodol. was also demonstrated by transformations of the reaction products.
