Quan, Cui published the artcileSynthesis of carbon nanotubes and porous carbons from printed circuit board waste pyrolysis oil, HPLC of Formula: 74896-66-5, the main research area is synthesis porous carbon printed circuit board waste pyrolysis oil; carbon nanotube synthesis printed circuit board waste pyrolysis oil.

The possibility and feasibility of using pyrolysis oil from printed circuit board (PCB) waste as a precursor for advanced carbonaceous materials is presented. The PCB waste was 1st pyrolyzed in a laboratory scale fixed bed reactor at 600° to prepare pyrolysis oil. The anal. of pyrolysis oil by gas chromatog.-mass spectroscopy indicated that it contained a very high proportion of phenol and phenol derivatives It was then polymerized in formaldehyde solution to synthesize pyrolysis oil-based resin which was used as a precursor to prepare C nanotubes (CNTs) and porous carbons. SEM and transmission microscopy investigation showed that the resulting CNTs had hollow cores with outer diameter of ∼338 nm and wall thickness of ∼86 nm and most of them were filled with metal nanoparticles or nanorods. X-ray diffraction reveals that CNTs have an amorphous structure. N adsorption isotherm anal. indicated the prepared porous carbons had a Brunauer-Emmett-Teller surface area of 1214 m2/g. The mechanism of the formation of the CNTs and porous carbons is discussed.

Jaradat, Nidal published the artcileIsolation, identification, and antimycotic activity of plumbagin from Plumbago europaea L. roots, leaves and stems, Formula: C12H23BrO2, the main research area is Plumbago root leaf stem plumbagin antimycotic.

Plumbago europaea L. is a plant utilized in Palestinian ethnomedicine for the treatment of various dermatol. diseases. The current investigation was designed to isolate plumbagin from P. europaea leaves, roots and for the first time from the stems. Moreover, it aimed to evaluate the antimycotic activity against three human fungal pathogens causing dermatophytosis, also against an animal fungal pathogen. The qual. anal. of plumbagin from the leaves, stems, and roots was conducted using HPLC and spectrophotometer techniques, while the structure of plumbagin was established utilizing Proton and Carbon-13 NMR (NMR) and IR (IR) techniques. The entire plant constituents were determined by GC-MS. Moreover, the antimycotic activity against Ascosphaera apis, Microsporum canis, Trichophyton rubrum, and Trichophyton mentagrophytes was assessed utilizing the poison food technique method. The percentage of plumbagin recorded in the leaves, stems, and roots was found to be 0.51±0.001%, 0.16±0.001%, and 1.65±0.015%, resp. The GC-MS examination declared the presence of 59 mols. in the plant extract The plant extract and pure plumbagin exhibited complete inhibition against all tested dermatophytes at 6.0mg/mL for the extracts and 0.2mg/mL for plumbagin. P. europaea root is the best source of plumbagin and the plant extract could represent a potential drug candidate for the treatment of dermatophytosis infections. Further studies required to design suitable dosage forms from the natural P. europaea root extracts or plumbagin alone, to be utilized for the treatment of dermatol. and veterinary ailments.

Rice, Kenneth D. published the artcilePyrazolopyrimidines as dual Akt/p70S6K inhibitors, SDS of cas: 74896-66-5, the main research area is pyrazolopyrimidine preparation Akt p70S6K inhibitor SAR.

Activation of the PI3K/Akt/mTOR kinase pathway is frequently associated with human cancer. Selective inhibition of p70S6 Kinase, which is the last kinase in the PI3K pathway, is not sufficient for strong tumor growth inhibition and can lead to activation of upstream proteins including Akt through relief of a neg. feedback loop. Targeting multiple sites in the PI3K pathway might be beneficial for optimal activity. In this manuscript we report the design of dual Akt/p70S6K inhibitors and the evaluation of the lead compound 11b (I) in vivo, which was eventually advanced into clin. development.

Boutard, Nicolas published the artcileDiscovery and structure-activity relationships of N-aryl 6-aminoquinoxalines as potent PFKFB3 kinase inhibitors, Recommanded Product: 4-Bromo-2-chloro-6-nitroaniline, the main research area is crystal structure neoplasm antitumor PFKFB3 kinase inhibitor aminoquinoxaline; cancer; enzymes; glycolysis; inhibitors; metabolism.

Energy and biomass production in cancer cells are largely supported by aerobic glycolysis in what is called the Warburg effect. The process is regulated by key enzymes, among which phosphofructokinase PFK-2 plays a significant role by producing fructose-2,6-biphosphate; the most potent activator of the glycolysis rate-limiting step performed by phosphofructokinase PFK-1. Herein, the synthesis, biol. evaluation and structure-activity relationship of novel inhibitors of 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 (PFKFB3), which is the ubiquitous and hypoxia-induced isoform of PFK-2, are reported. X-ray crystallog. and docking were instrumental in the design and optimization of a series of N-aryl 6-aminoquinoxalines. The most potent representative, N-(4-methanesulfonylpyridin-3-yl)-8-(3-methyl-1-benzothiophen-5-yl)quinoxalin-6-amine, displayed an IC50 of 14 nM for the target and an IC50 of 0.49 μM for fructose-2,6-biphosphate production in human colon carcinoma HCT116 cells. This work provides a new entry in the field of PFKFB3 inhibitors with potential for development in oncol.

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.

Kuo, Gee-Hong published the artcileSynthesis and structure-activity relationships of pyrazine-pyridine biheteroaryls as novel, potent, and selective vascular endothelial growth factor receptor-2 inhibitors, Computed Properties of 41668-13-7, the main research area is pyridinyltin dichloropyrazine Stille coupling; chloropyrazine pyridine preparation; pyrazine pyridine derivative preparation VEGFR2 ligand; pyridine pyrazine derivative preparation anticancer.

There is much evidence that direct inhibition of the kinase activity of vascular endothelial growth factor receptor-2 (VEGFR-2) will result in the reduction of angiogenesis and the suppression of tumor growth. Palladium-catalyzed C-C bond, C-N bond formation reactions were used to assemble various pyrazine-pyridine biheteroaryls as potent VEGFR-2 inhibitors. Among them, I [R = NH(CH2)4OH, NH(CH2)2NMe2] exhibited the highest kinase selectivity against fibroblast growth factor receptor kinase, platelet-derived growth factor receptor kinase, and glycogen synthase kinase-3. All of these compounds showed good cellular potency to inhibit VEGF-stimulated proliferation of human umbilical vein endothelial cells (HUVEC) but with modest effects on the unstimulated growth of HUVEC. The low inhibition of these compounds to the growth of tumor cell lines, such as HeLa, HCT-116, and A375 further confirms that these VEGFR-2 inhibitors are not cytotoxic agents. The in vivo antitumor activity of I were demonstrated in the A375 human melanoma xenograft nude mice model. Mol. modeling (QSAR anal.) was conducted in an attempt to rationalize the observed structure-activity relationship.

Melin, Lea published the artcileDevelopment of LM98, a Small-Molecule TEAD Inhibitor Derived from Flufenamic Acid, Quality Control of 647020-71-1, the main research area is anticancer agent cell migration TEAD LM98 flufenamic acid; Flufenamic acid; Hippo pathway; SAR; TEAD; palmitic acid.

The YAP-TEAD transcriptional complex is responsible for the expression of genes that regulate cancer cell growth and proliferation. Dysregulation of the Hippo pathway due to overexpression of TEAD has been reported in a wide range of cancers. Inhibition of TEAD represses the expression of associated genes, demonstrating the value of this transcription factor for the development of novel anti-cancer therapies. We report herein the design, synthesis and biol. evaluation of LM98, a flufenamic acid analog. LM98 shows strong affinity to TEAD, inhibits its autopalmitoylation and reduces the YAP-TEAD transcriptional activity. Binding of LM98 to TEAD was supported by 19F-NMR studies while co-crystallization experiments confirmed that LM98 is anchored within the palmitic acid pocket of TEAD. LM98 reduces the expression of CTGF and Cyr61, inhibits MDA-MB-231 breast cancer cell migration and arrests cell cycling in the S phase during cell division.

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.
