Inhibitors targeting the epidermal growth factor receptor (EGFR) are an effective therapy for patients with non-small cell lung cancer harboring drug-sensitive activating mutations in the EGFR kinase domain. Drug resistance due to treatment-acquired mutations has motivated the development of successive generations of inhibitors that bind in the ATP site. The third-generation agent osimertinib is now a first-line treatment for this disease. Recently, allosteric inhibitors have been developed to overcome drug-resistant mutations that confer a resistance to osimertinib. Here, we present the structure-guided design and synthesis of a mutant-selective lead compound, which consists of a pyridinyl imidazole-fused benzylisoindolinedione scaffold that simultaneously occupies the orthosteric and allosteric sites. The compound potently inhibits enzymic activity in L858R/T790M/C797S mutant EGFR (4.9 nM), with a significantly lower activity for wild-type EGFR (47 nM). Addnl., this compound achieves modest cetuximab-independent and mutant-selective cellular efficacies on the L858R (1.2 μM) and L858R/T790M (4.4 μM) variants.

Electric Literature of 5382-16-1, 4-Hydroxypiperidine is a molecule with a carbonyl group. It is the most active and selective CCR5 receptor antagonist that has been studied to date. 4-Hydroxypiperidine inhibits HIV infection by preventing the binding of HIV to its receptor on the surface of white blood cells, thereby preventing it from entering these cells. 4-Hydroxypiperidine also acts as an anti-inflammatory agent in chronic bronchitis patients, due to its ability to inhibit prostaglandin synthesis. The chemical ionization mass spectra of this molecule show peaks for methyl ethyl, malic acid, and hydroxyl groups. These properties make 4-hydroxypiperidine a useful candidate for drug development against inflammatory diseases and several cancers.
The molecular structure, vibrational spectra, NBO and UV-spectral analysis of 4-Hydroxypiperidine have been studied. The compounds with a substituted 4-piperidinol core have been found to be potent antagonists of the human H receptor., 5382-16-1.

Multitarget-directed ligands are a promising class of drugs for discovering innovative new therapies for difficult to treat diseases. In this study, we designed dual inhibitors targeting the human fatty acid amide hydrolase (FAAH) enzyme and human soluble epoxide hydrolase (sEH) enzyme. Targeting both of these enzymes concurrently with single target inhibitors synergistically reduces inflammatory and neuropathic pain; thus, dual FAAH/sEH inhibitors are likely to be powerful analgesics. Here, we identified the piperidinyl-sulfonamide moiety as a common pharmacophore and optimized several inhibitors to have excellent inhibition profiles on both targeted enzymes simultaneously. In addition, several inhibitors show good predicted pharmacokinetic properties. These results suggest that this series of inhibitors has the potential to be further developed as new lead candidates and therapeutics in pain management.

Wilt, Stephanie R.;Rodriguez, Mark;Le, Thanh N. H.;Baltodano, Emily V.;Salas, Adrian;Pecic, Stevan research published 《 Design, microwave-assisted synthesis, biological evaluation and molecular modeling studies of 4-phenylthiazoles as potent fatty acid amide hydrolase inhibitors》, the research content is summarized as follows. Endocannabinoids, anandamide (AEA) and 2-arachidonoylglycerol (2-AG), are endogenous lipids that activate cannabinoid receptors. Activation of these receptors produces anti-inflammatory and analgesic effects. Fatty acid amide hydrolase (FAAH) is a membrane enzyme that hydrolases endocannabinoids; thus, inhibition of FAAH represents an attractive approach to develop new therapeutics for treating inflammation and pain. Previously, potent rat FAAH inhibitors containing 2-naphthyl- and 4-phenylthiazole scaffolds were identified, but up to the present time, very little structure-activity relationship studies have been performed on these moieties. We designed and synthesized several analogs containing these structural motifs and evaluated their inhibition potencies against human FAAH enzyme. In addition, we built and validated a homol. model of human FAAH enzyme and performed docking experiments We identified several inhibitors in the low nanomolar range and calculated their ADME predicted values. These FAAH inhibitors represent promising drug candidates for future preclin. in vivo studies.

The silicon (Si) site location in silicoaluminophosphate zeolites has significant influences on their acidic and catalytic properties. Herein, AEI analog silicoaluminophosphates with controlled tetrahedral silicon centers (T sites) were synthesized using specially designed amines as expected organic structure-directing agents (OSDAs). DFT calculations show that the OSDAs with different electronegativity can direct Si atoms into the T sites with more favorable energy advantages. Their catalytic performances in a methanol-to-olefin (MTO) reaction also reflected that OSDAs controlled the Si location in the framework, and the T3 sites had better performance than T1 sites. This finding provides evidence that OSDAs are capable of guiding the Si ions into more favorable T sites, achieving desirable catalytic properties as solid acid catalysts.

Wei, Mingyu;Shi, Xiaowen;Xiao, Ling;Zhang, Haifei research published 《 Synthesis of polyimide-modified carbon nanotubes as catalyst for organic pollutant degradation via production of singlet oxygen with peroxymonosulfate without light irradiation》, the research content is summarized as follows. Polyimide-modified carbon nanotubes (PI/CNTs) were synthesized via a solvent-free thermal method and used as a metal-free catalyst to activate peroxymonosulfate for organic contaminant degradation without light irradiation The characterization results suggested that PI was loaded onto the surface of CNTs. The catalytic ability of the PI/CNTs was strongly correlated with the content of PI in the catalysts. The PI/CNTs (22% of PI) showed the highest catalytic efficiency for organic pollutant degradation at room temperature The degradation efficiency of acid orange 7 (AO7) dye was significantly enhanced to 98.9% within 15 min, compared to the efficiency of 2.2% exhibited by pure PI. The radical quenching tests and ESR spectrometry proved that singlet oxygen, instead of hydroxyl radicals or sulfate radicals, played a dominant role during the catalytic oxidation of AO7. The influences of operation parameters including temperature and catalyst amount were investigated. The PI/CNTs metal-free catalyst exhibited high catalytic activity under a broad range of pH values. The recycling study of four repeated reactions demonstrated good stability of the PI/CNTs. This work provided a promising metal-free catalyst for degradation of organic pollutants in aqueous solutions, contributing to the development of green materials for sustainable remediation.

The interpretation of histone post-translational modifications (PTMs), specifically lysine methylation, by specific classes of “reader” proteins marks an important aspect of epigenetic control of gene expression. Methyl-lysine (Kme) readers often regulate gene expression patterns through the recognition of a specific Kme PTM while participating in or recruiting large protein complexes that contain enzymic or chromatin remodeling activity. Understanding the composition of these Kme-reader-containing protein complexes can serve to further our understanding of the biol. roles of Kme readers, while small mol. chem. tools can be valuable reagents in interrogating novel protein-protein interactions. Here, we describe our efforts to target the chromodomain of M-phase phosphoprotein 8 (MPP8), a member of the human silencing hub (HUSH) complex and a histone 3 lysine 9 tri-Me (H3K9me3) reader that is vital for heterochromatin formation and has specific roles in cancer metastasis. Utilizing a one-bead, one-compound (OBOC) combinatorial screening approach, we identified UNC5246, a peptidomimetic ligand capable of interacting with the MPP8 chromodomain in the context of the HUSH complex. Addnl., a biotinylated derivative of UNC5246 facilitated chemoproteomics studies which revealed hepatoma-derived growth factor-related protein 2 (HRP2) as a novel protein associated with MPP8. HRP2 was further shown to colocalize with MPP8 at the E-cadherin gene locus, suggesting a possible role in cancer cell plasticity.

Wang, Yu;Wu, Yang;Yu, Yafei;Pan, Tao;Li, Dantong;Lambropoulou, Dimitra;Yang, Xin research published 《 Natural polyphenols enhanced the Cu(II)/peroxymonosulfate (PMS) oxidation: The contribution of Cu(III) and HO^•》, the research content is summarized as follows. Copper ion (Cu(II)) in water or wastewater has been reported to trigger peroxymonosulfate (PMS) oxidation of organic contaminants (OCs). However, this process can only work in alk. condition, which limits its potential application. In this study, we found that the introduction of natural polyphenols in the Cu(II)/PMS process can significantly promote the degradation of tetrabromobisphenol A (TBBPA), one of the most widely used brominated flame retardants, in the pH range of 4.3-9.0. With gallic acid (GA) as a representative natural polyphenol, the degradation of TBBPA by GA/Cu(II)/PMS process reached 84.6% in 10 min at initial pH of 4.3 (without pH adjustment), which was 2.2 times higher than that by Cu(II)/PMS process. Multiple reactive oxidants, including Cu(III), hydroxyl radical (HO•) and singlet oxygen, were generated in this process among which Cu(III) and HO• contributed to TBBPA degradation with Cu(III) playing the dominant role. GA accelerated the reduction of Cu(II) to Cu(I) due to the strong chelation and electron-donating capacity of ortho-hydroxyl groups in GA, and then Cu(I) was quickly oxidized by PMS to Cu(III) which can be further acid-catalyzed to produce HO•. TBBPA transformation mainly proceeded through electron abstraction, oxidative debromination and ring-opening reaction pathways. The feasibility of in-situ utilizing natural organic matter (NOM, enriched with polyphenol moieties) to accelerate the degradation of TBBPA by Cu(II)/PMS process in surface water and wastewater was confirmed. The findings of this study indicate that the coupling of NOM and Cu(II), which are present in contaminated water or wastewater, can potentially improve PMS oxidation of OCs in a wide range of pH.

This work demonstrated that bisphenol A (BPA) was rapidly degraded by peroxymonosulfate (PMS) in the presence of amorphous manganese dioxide (MnO₂). Chem. quenching experiments and ESR spectroscopy (EPR) suggested that hydroxyl radical (^·OH), sulfate radical (SO^·-₄), and singlet oxygen (¹O₂) were unlikely responsible for BPA oxidation As such, a nonradical mechanism involving the formation of reactive complexes between amorphous MnO₂ and PMS was tentatively proposed based on the PMS decomposition and Raman spectra. The presence of phosphate ions (H₂PO^–₄) remarkably suppressed the degradation of BPA, while the addition of divalent metal ions (Ca²⁺, Mg²⁺, and Zn²⁺) appreciably enhanced BPA degradation The discrepancy was likely resulted from their contrasting influences on the formation of reactive PMS-MnO₂ complexes. Based on identified oxidation products (i.e., dimers, 4-hydroxycumyl alc., mono-hydroxylated BPA and its quinone derivative) by liquid chromatog. tandem mass spectrometry, the transformation pathways of BPA in amorphous MnO₂/PMS system involving one-electron oxidation, radical coupling, bond cleavage, and hydroxylation were proposed. In addition to BPA, thirteen other selected phenolic compounds were also efficiently degraded by amorphous MnO₂/PMS system, and good correlations between apparent pseudo-first-order reaction rate constants (k_obs) and descriptor variables (i.e., Hammett constants σ⁺ and half-wave potentials E_1/2) were obtained.
