Application of 4265-25-2, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Conference Paper, and a compound is mentioned, 4265-25-2, 2-Methylbenzofuran, introducing its new discovery.

The present work studies first the kinetics of the global primary thermal decomposition of raw waste lubricant oils in helium atmosphere conditions and with different proportions of helium:oxygen by TGA. In addition, pyrolysis and partial oxidation runs were carried out in a tubular reactor at 723 and 1123 K, where the volatiles and semivolatiles evolved were quantified by gas chromatography. TGA analysis shows nearly no difference between helium and helium-oxygen atmosphere, yielding no appreciable residue. Primary decomposition, which takes place between 450 and 700 K, can be modeled with two different processes: the main one (92.6% of the initial material) is an evaporation of the motor oil (with apparent zero order and a kinetic constant dependent on the mass and heating rate) and a small contribution of a typical solid carbonoceous pyrolysis. In the tubular reactor, gases evolved in pyrolysis at 773 K corroborate TG findings that the process is mainly an evaporation, with little changes with respect to the original chemical structure of the oil. Nevertheless, the gas composition changes completely in the presence of air, where the partial oxidation in the gas phase after evaporation yields lower chain paraffins and olefines. Gas evolution at 1123 K is completely different, yielding showing typical cracked flue gas composition: light gases with abundant olefins and poly-condensed aromatics.

Anaplastic lymphoma kinase (ALK) is a major target in treating non-small-cell lung cancer, and several ALK inhibitors have been developed to antagonize its kinase activity. However, patients treated with inhibitors ultimately develop drug resistance. Therefore, therapies with new mechanisms of action are needed. Proteolysis targeting chimeras (PROTACs) are molecules that comprise a ligand for binding a protein of interest (POI), a connecting linker and a ligand for recruiting E3 ligase, and cause degradation of the target POI. Here, the first multi-headed PROTAC, as a proof of concept, is developed as a gold nanoparticle (GNP)-based drug delivery system for delivering PROTACs to target ALK. Pegylated GNPs loaded with both ceritinib and pomalidomide molecules, termed Cer/Pom-PEG@GNPs, showed good stability in several media. The GNP conjugates potently decreased the levels of ALK fusion proteins in a dose- and time-dependent manner, and specifically inhibited the proliferation of NCI-H2228 cells. In comparison with small molecule PROTACs, the new multi-headed PROTAC promoted the formation of coacervates of POIs/multi-headed PROTAC/E3 ubiquitin ligases, and POI and E3 ubiquitin ligase interacted through multidirectional ligands and a flexible linker, thereby avoiding the need for complicated structure optimization of PROTACs. In conclusion, Cer/Pom-PEG@GNPs can degrade intracellular ALK fusion proteins with minor off-target toxicity and can be applied in patients resistant to ALK inhibitors. As a nano-based drug carrier, Cer/Pom-PEG@GNPs have the potential to enable prolonged circulation and specifically distribute drugs to tumor regions in vivo; thus, further investigation is warranted.

Novel N-substituted phthalimides (2-substituted 1H-isoindole-1,3- diones) were prepared, and their effects on tumor necrosis factor-alpha (TNF- alpha) production by human leukemia cell line HL-60 stimulated with 12-O- tetradecanoylphorbol 13-acetate (TPA) or okadaic acid (OA) were examined. A structure-activity relationship study of the N-phenylphthalimides and N- benzylphthalimides revealed that their enhancing effect on TPA-induced TNF- alpha production by HL-60 cells and their inhibiting effect on OA-induced TNF- alpha production by HL-60 cells are only partially correlated.

We report a multi-objective de novo design study driven by synthetic tractability and aimed at the prioritization of computer-generated 5-HT2B receptor ligands with accurately predicted target-binding affinities. Relying on quantitative bioactivity models we designed and synthesized structurally novel, selective, nanomolar, and ligand-efficient 5-HT2B modulators with sustained cell-based effects. Our results suggest that seamless amalgamation of computational activity prediction and molecular design with microfluidics-assisted synthesis enables the swift generation of small molecules with the desired polypharmacology.

The aim of this work is to investigate the chemical, physical, thermal and mechanical properties of bio-oil-phenol?formaldehyde (BPF) resin synthesized with catalytic pyrolysis oil. In this way, catalysed and uncatalysed pyrolysis processes were carried out in a vacuum pyrolysis reactor at the temperature of 500C. Sodium hydroxide (NaOH) and potassium hydroxide (KOH) were used as catalysts in the catalysed pyrolysis processes. The BPF resins were synthesized using the bio-oil at 10 wt%, 20 wt%, 30 wt%, 40 wt% and 50 wt% phenol replacement levels. The chemical composition of the bio-oil was analyzed by GC/MS analysis. The thermal characteristics and chemical structures of the resins were characterized by TGA and FT-IR analysis, respectively. Physical properties including pH, viscosity, solid content and gel time of the resins were determined. Oriented Strand Board (OSB) were manufactured to evaluate the mechanical performances of modified resins. The BPF resins were successfully synthesized with phenol, bio-oil and formaldehyde. BPF resins synthesized with catalytic bio-oils showed better thermal stability than BPF resin synthesized with non-catalytic bio-oil. The mechanical test results showed that the IB strengths of OSBs made with BPF resins synthesized by use of NaOH exhibited better performance than OSBs commercial PF made.

Discovery of new drug binding sites on well-established targets is of great interest as it facilitates the design of new mechanistic inhibitors to overcome the acquired drug resistance. Small chemical fragments can easily enter and bind to the cavities on the protein surface. Thus, they can be used to probe new druggable pockets in proteins. DNA gyrase plays indispensable roles in DNA replication, and both its GyrA and GyrB subunits are clinically validated antibacterial targets. New mechanistic GyrB inhibitors are urgently desired since the withdrawal of novobiocin from the market by the FDA due to its reduced efficiency and other reasons. Here, a fragment library was screened against the E. coli GyrB ATPase domain by combining affinity- and bioactivity-based approaches. The following X-ray crystallographic efforts were made to determine the cocrystal structures of GyrB with ten fragment hits, and three different binding modes were disclosed. Fortunately, a hydrophobic pocket which is previously unknown was identified by two fragments. Fragments that bind to this pocket were shown to inhibit the ATPase activity as well as the DNA topological transition activity of DNA gyrase in vitro. A set of fragment analogs were screened to explore the binding capacity of this pocket and identify the better starting fragments for lead development. Phylogenetic analysis revealed that this pocket is conserved in most Gram-negative and also many Gram-positive human pathogenic bacteria, implying a broad-spectrum antibacterial potential and a lower risk of mutation. Thus, the novel druggable pocket and the starting fragments provide a novel basis for designing new GyrB-targeting therapeutics.

Development of selective kinase inhibitors that target the ATP binding site continues to be a challenge largely due to similar binding pockets. Palbociclib is a cyclin-dependent kinase inhibitor that targets the ATP binding site of CDK4 and CDK6 with similar potency. The enzymatic function associated with the kinase can be effectively probed using kinase inhibitors however the kinase-independent functions cannot. Herein, we report a palbociclib based PROTAC that selectively degrades CDK6 while sparing the homolog CDK4. We used competition studies to characterize the binding and mechanism of CDK6 degradation.
