Bugday, Nesrin published the artcilePalladium nanoparticle supported on nitrogen-doped porous carbon: Investigation of structural properties and catalytic activity on Suzuki-Miyaura reactions, Computed Properties of 452-63-1, the main research area is nitrogen doped porous carbon supported palladium nanoparticle preparation; phenylboronic acid halobenzene palladium catalyst Suzuki Miyaura coupling green; biphenyl preparation.

Novel palladium-doped nanoporous carbon composite material obtained via thermolysis of amorphous zeolitic imidazolate framework (aZIF) was synthesized and used as an efficient catalyst on Suzuki-Miyaura cross-coupling reactions of aryl bromides. With this developed catalytic system, the Suzuki-Miyaura cross-coupling reaction was accomplished in aqueous solutions, and biaryls were obtained in good to excellent yields in a short reaction time. The APC-750@Pd catalyst was characterized by Fourier Transform IR spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Eicroscopy (SEM), XPS, Transmission Electron Microscopy (TEM), Thermal Gravimetric Anal. (TGA), DTA (DTA), Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Brunauer-Emmett-Teller (BET) anal. tecniques. N-doped porous carbon material (NPC-1000) was synthesized by thermolysis from aZIF. Activated porous carbon material (APC-750) was fabricated via fused at 750°C with KOH from NPC-1000. The APC-750@Pd was obtained as a result of the interaction of APC-750 and PdCl2 in deionized water. The cross-coupling reaction of different aryl bromides with phenylboronic acid was investigated to show the potential of the APC-750@Pd in the Suzuki-Miyaura cross-coupling reactions. The APC-750@Pd catalyst could be recycled at least five times with a 15% loss of catalytic efficiency in this catalytic system.

Xiong, Rui published the artcileNovel Selective Estrogen Receptor Downregulators (SERDs) Developed against Treatment-Resistant Breast Cancer, Category: bromides-buliding-blocks, the main research area is estrogen receptor downregulator SERD antitumor breast cancer.

Resistance to the selective estrogen receptor modulator (SERM) tamoxifen and to aromatase inhibitors that lower circulating estradiol occurs in up to 50% of patients, generally leading to an endocrine-independent ER+ phenotype. Selective ER downregulators (SERDs) are able to ablate ER and thus theor. to prevent survival of both endocrine-dependent and independent ER+ tumors. The clin. SERD, fulvestrant, is hampered by i.m. administration and undesirable pharmacokinetics. Novel SERDs were designed using the 6-OH-benzothiophene (BT) scaffold common to arzoxifene and raloxifene. Treatment-resistant (TR) ER+ cell lines (MCF-7:5C and MCF-7:TAM1) were used for optimization, followed by validation in the parent endocrine-dependent cell line (MCF-7:WS8), in 2D and 3D cultures, using ERα in-cell westerns, ERE-luciferase, and cell viability assays, with GDC-0810 (ARN-810) used for comparison. Two BT SERDs with superior in vitro activity to GDC-0810 were studied for bioavailability and shown to cause regression of a TR, endocrine-independent ER+ xenograft superior to GDC-0810.

Masillamani, Appan Merari published the artcileMultiscale Charge Injection and Transport Properties in Self-Assembled Monolayers of Biphenyl Thiols with Varying Torsion Angles, Application of 1-Bromo-4-fluoro-2-methylbenzene, the main research area is multiscale charge transport self assembled biphenyl thiol.

This article describes the mol. structure-function relation for biphenylthiol derivatives with varying torsional degree of freedom in their mol. backbone when self-assembled on gold electrodes. These biphenylthiol mols. chemisorbed on Au exhibit different tilt angles with respect to the surface normal and different packing densities. The charge transport through the biphenylthiol self-assembled monolayers (SAMs) showed a characteristic decay trend with the effective monolayer thickness. Based on parallel pathways model the tunneling decay factor β is 0.27 Å-1. The hole mobility of poly(3-hexylthiophene)-based thin-film transistors incorporating a biphenylthiol SAM coating the Au source and drain electrodes revealed a dependence on the injection barrier with the HOMO level of the semiconductor. The possible role of the resistivity of the SAMs on transistor electrodes on the threshold voltage shift is discussed. The control over the chem. structure, electronic properties, and packing order of the SAMs provides a versatile platform to regulate the charge injection in organic electronic devices.

Cacheux, Fanny published the artcileThe Piancatelli rearrangement of non-symmetrical furan-2,5-dicarbinols for the synthesis of highly functionalized cyclopentenones, Computed Properties of 452-63-1, the main research area is hydroxymethyl hydroxycyclopentenone preparation regioselective diastereoselective antitumor activity microwave irradiation; furan dicarbinol preparation Piancatelli rearrangement dysprosium chloride catalyst; aminocyclopentenone preparation regioselective diastereoselective microwave irradiation; aniline furan dicarbinol Aza Piancatelli rearrangement.

Substituted and non-sym. furan-2,5-dicarbinols I (R = Ph, 4-fluoro-2-methylphenyl, phenanthren-9-yl, 1,3-benzodioxol-5-yl, etc.) were readily prepared from 5-(hydroxymethyl)furfural (HMF), a renewable raw material from biomass. The Piancatelli rearrangement of these furan-2,5-dicarbinols I, catalyzed by DyCl3and under microwave activation, affords 5-substituted-4-hydroxymethyl-4-hydroxycyclopentenones (4S,5R)/(4S,5S)-II in a regio- and diastereoselective manner. This methodol. can be extended to aza-Piancatelli type reactions by using nitrogen nucleophiles, to furnish the corresponding aminocyclopentenone derivatives III (R1 = I, Br). Some of these synthesized bis-hydroxylated cyclopentenone derivatives exhibited significant cytotoxicity against eight human tumor cell lines.

Tria, George S. published the artcileDiscovery of LSZ102, a Potent, Orally Bioavailable Selective Estrogen Receptor Degrader (SERD) for the Treatment of Estrogen Receptor Positive Breast Cancer, Synthetic Route of 452-63-1, the main research area is benzothiophene preparation selective estrogen receptor degrader breast cancer treatment.

In breast cancer, estrogen receptor alpha (ERα) pos. cancer accounts for approx. 74% of all diagnoses, and in these settings, it is a primary driver of cell proliferation. Treatment of ERα pos. breast cancer has long relied on endocrine therapies such as selective estrogen receptor modulators, aromatase inhibitors, and selective estrogen receptor degraders (SERDs). The steroid-based anti-estrogen fulvestrant, the only approved SERD, is effective in patients who have not previously been treated with endocrine therapy as well as in patients who have progressed after receiving other endocrine therapies. Its efficacy, however, may be limited due to its poor physicochem. properties. THe authors describe the design and synthesis of a series of potent benzothiophene-containing compounds that exhibit oral bioavailability and preclin. activity as SERDs. This article culminates in the identification of LSZ102 (I), a compound in clin. development for the treatment of ERα pos. breast cancer.

Henry, James R. published the artcileDiscovery of 1-(3,3-Dimethylbutyl)-3-(2-fluoro-4-methyl-5-(7-methyl-2-(methylamino)pyrido[2,3-d]pyrimidin-6-yl)phenyl)urea (LY3009120) as a Pan-RAF Inhibitor with Minimal Paradoxical Activation and Activity against BRAF or RAS Mutant Tumor Cells, Name: 1-Bromo-4-fluoro-2-methylbenzene, the main research area is antitumor RAF inhibitor LY3009120 preparation structure activity cancer.

The RAS-RAF-MEK-MAPK cascade is an essential signaling pathway, with activation typically mediated through cell surface receptors. The kinase inhibitors vemurafenib and dabrafenib, which target oncogenic BRAF V600E, have shown significant clin. efficacy in melanoma patients harboring this mutation. Because of paradoxical pathway activation, both agents were demonstrated to promote growth and metastasis of tumor cells with RAS mutations in preclin. models and are contraindicated for treatment of cancer patients with BRAF WT background, including patients with KRAS or NRAS mutations. To eliminate the issues associated with paradoxical MAPK pathway activation and to provide therapeutic benefit to patients with RAS mutant cancers, we sought to identify a compound not only active against BRAF V600E but also wild type BRAF and CRAF. On the basis of its superior in vitro and in vivo profile, compound 13 was selected for further development and is currently being evaluated in phase I clin. studies.

Ball, Liam T. published the artcileGold-Catalyzed Oxidative Coupling of Arylsilanes and Arenes: Origin of Selectivity and Improved Precatalyst, Recommanded Product: 1-Bromo-4-fluoro-2-methylbenzene, the main research area is gold catalyzed oxidative coupling arylsilane arene.

The mechanism of gold-catalyzed coupling of arenes with aryltrimethylsilanes has been investigated, employing an improved precatalyst (thtAuBr3) to facilitate kinetic anal. In combination with linear free-energy relationships, kinetic isotope effects, and stoichiometric experiments, the data support a mechanism involving an Au(I)/Au(III) redox cycle in which sequential electrophilic aromatic substitution of the arylsilane and the arene by Au(III) precedes product-forming reductive elimination and subsequent cycle-closing reoxidation of the metal. Despite the fundamental mechanistic similarities between the two auration events, high selectivity is observed for heterocoupling (C-Si then C-H auration) over homocoupling of either the arylsilane or the arene (C-Si then C-Si, or C-H then C-H auration); this chemoselectivity originates from differences in the product-determining elementary steps of each electrophilic substitution. The turnover-limiting step of the reaction involves associative substitution en route to an arene π-complex. The ramifications of this insight for implementation of the methodol. are discussed.
