A review. Rheumatoid arthritis (RA) is an autoimmune disease involving joints, with clin. manifestations of joint inflammation, bone damage and cartilage destruction, joint dysfunction and deformity, and extra-articular organ damage. As an important source of new drug mols., natural medicines have many advantages, such as a wide range of biol. effects and small toxic and side effects. They have become a hot spot for the vast number of researchers to study various diseases and develop therapeutic drugs. In recent years, the research of natural medicines in the treatment of RA has made remarkable achievements. These natural medicines mainly include flavonoids, polyphenols, alkaloids, glycosides and terpenes. Among them, resveratrol, icariin, epigallocatechin-3-gallate, ginsenoside, sinomenine, paeoniflorin, triptolide and paeoniflorin are star natural medicines for the treatment of RA. Its mechanism of treating RA mainly involves these aspects: anti-inflammation, anti-oxidation, immune regulation, pro-apoptosis, inhibition of angiogenesis, inhibition of osteoclastogenesis, inhibition of fibroblast-like synovial cell proliferation, migration and invasion. This review summarizes natural medicines with potential therapeutic effects on RA and briefly discusses their mechanisms of action against RA.

Since high grade gliomas are aggressive brain tumors, intensive search for new treatment options is ongoing. For adult patients with newly diagnosed (ndGBM) and recurrent glioblastoma (rGBM), low intensity intermediate frequency alternating electric fields, known as tumor treating fields (TTFields) have been established as a new treatment modality. Tumor treating fields significantly increase survival rates in combination with adjuvant temozolomide (TMZ) in adult and GBM patients. Here, we report about feasibility and safety of treatment on a pediatric patient with diffuse midline glioma who is receiving TTFields therapy in combination with temozolomide.

Al-Zaban, Mayasar I.; AlHarbi, Maha A.; Mahmoud, Mohamed A.; Bahatheq, Aisha M. published the artcile< Production of biodiesel from oleaginous fungal lipid using highly catalytic bimetallic gold-silver core-shell nanoparticle>, HPLC of Formula: 112-63-0, the main research area is gold silver core shell nanoparticle biodiesel oleaginous fungal lipid; biodiesel; fungal lipids; gold-silver core-shell nanoparticles; optimization; transesterification.

This study aims to synthesize, characterize and apply gold-silver core-shell nanoparticles (Au@Ag NPs), a nanocatalyst, to maximize biodiesel production from fungal isolate Fusarium solani (FS12) via a transesterification one-step reaction. The Au@Ag NPs structure was examined by UV-vis spectrophotometer, transmission electron microscopy, X-ray diffraction and Fourier transform IR (FTIR). All devices were used to characterize Au@Ag NPs and confirmed successful synthesis of nanoparticles. Fungal lipid was quant. determined by sulfo-phospho-vanillin colorimetric method. Among 15 F. solani isolates obtained from rhizospheric soils of the date palm, F. solani (AF12) was chosen as the highly significant producer that accumulates above 20% lipid. The maximum biodiesel yield was 91.28 ± 0.19%, obtained under the optimum reaction conditions of 3% Au@Ag NPs as nanocatalyst concentration, and 1:20 oil to methanol molar ratio at 70°C for 30 min. HPLC method was applied for monitoring in situ transesterification reaction. FTIR spectroscopy was used in qual. anal. of biodiesel by verifying the presence of unique characteristic peaks of diagnostic significance. The quality of the biodiesel produced was confirmed by the high purity of fatty acid Me esters anal. content up to >99%. These findings propose the applicability of F. solani (FS12) as a promising isolate to accumulate lipids and biodiesel production as a feedstock. Significance and Impact of the Study : The link between nanotechnol. and fungi. Au@Ag NPs were synthesized at room temperature, which displayed high catalytic activity for in situ transesterification reaction. Catalytic activity appeared at low temperature, mole ratio and short reaction time. Oleaginous fungi are described as easily grown, have short life cycle, are cost-effective, and they utilized various sources of carbon up to waste and a simplified process to develop scale-up production as well, economic value, opposite the usage of vegetable oils which need for large agricultural areas.

Li, Lin; Xu, Zhongzheng; Sun, Wen; Chen, Jia; Dai, Caili; Yan, Bin; Zeng, Hongbo published the artcile< Bio-inspired membrane with adaptable wettability for smart oil/water separation>, Formula: C9H3F5O2, the main research area is bio inspired membrane adaptable wettability separation.

Adaptable wettability is an intriguing property found in nature yet rare in synthetic materials. Separation membranes bearing this adaptable wettability would be of great significance for practical applications because they can achieve on-demand oil/water separation according to the intrinsic properties of the targeting oil/water mixtures other than external stimuli. Herein, we report one novel type of such smart separation membranes by functionalizing steel mesh membrane with polydopamine (PDA) and an amphiphilic synthetic copolymer via a feasible mussel-inspired dip-coating method. The resulting membrane possesses excellent adaptable wettability and can switch their special oil/water wettability to selectively activate “”water-removing”” or “”oil-removing”” modes for on-demand collection of the desired component (water or oil) from the oily water, i.e., upon pre-wetting the surfaces with water or oil. It exhibits outstanding performance in separating various immiscible oil/water mixtures and miscible surfactant-stabilized emulsions under ambient pressure. Moreover, the bio-inspired membrane can be regenerated and reused facilely through simple washing and drying process without loss in performance. The facile surface functionalization approach developed in this work is universal and substrate-independent, which can be extended to a variety of materials and membrane systems. Such universal surface modification method and the novel membrane developed have great application potential in various engineering and environmental areas including oil spill cleanup and industrial wastewater treatment.

Cotrina, Ellen Y.; Blasi, Daniel; Vila, Marta; Planas, Antoni; Abad-Zapatero, Cele; Centeno, Nuria B.; Quintana, Jordi; Arsequell, Gemma published the artcile< Optimization of kinetic stabilizers of tetrameric transthyretin: A prospective ligand efficiency-guided approach>, SDS of cas: 112-63-0, the main research area is ligand efficiency guided preparation transthyretin fibrillogenesis inhibitor iododiflunisal; Drug discovery; Inhibitors; Iododiflunisal; LEI-based approach; Ligand efficiency indices (LEI); Protein–ligand interactions; TTR tetramer stabilizer; Transthyretin.

In the past few years, attempts have been made to use decision criteria beyond Lipinski’s guidelines (Rule of five) to guide drug discovery projects more effectively. Several variables and formulations have been proposed and investigated within the framework of multiparameter optimization methods to guide drug discovery. In this context, the combination of Ligand Efficiency Indexes (LEI) has been predominantly used to map and monitor the drug discovery process in a retrospective fashion. Here we provide an example of the use of a novel application of the LEI methodol. for prospective lead optimization by using the transthyretin (TTR) fibrillogenesis inhibitor iododiflunisal (IDIF) as example. Using this approach, a number of compounds with theor. efficiencies higher than the reference compound IDIF were identified. From this group, ten compounds were selected, synthesized and biol. tested. Half of the compounds (5, 6, 7, 8 and 10) showed potencies in terms of IC50 inhibition of TTR aggregation equal or higher than the lead compound These optimized compounds mapped within the region of more efficient candidates in the corresponding exptl. nBEI-NSEI plot, matching their position in the theor. optimization plane that was used for the prediction. Due to their upstream (North-Eastern) position in the progression lines of NPOL = 3 or 4 of the nBEI-NSEI plot, three of them (5, 6 and 8) are more interesting candidates than iododiflunisal because they have been optimized in the three crucial LEI variables of potency, size and polarity at the same time. This is the first example of the effectiveness of using the combined LEIs within the decision process to validate the application of the LEI formulation for the prospective optimization of lead compounds

Amburgey-Peters, Judith C.; Haynes, LeRoy W. published the artcile< The addition of bromine to 1,2-diphenylethene>, Reference of 112-63-0, the main research area is chem education bromination diphenylethene pyridinium bromide perbromide bromine solvent.

The bromination of 1,2-diphenylethene, using a variety of solvents and brominating agents, can be used in both introductory and advanced organic chem. courses. The reactions can be used to illustrate the effects of changing solvents and reagents, as well as to reveal interesting aspects of organic reaction mechanisms. Experiments were carried out involving the addition of two brominating agent, pyridinium bromide perbromide (PBPB) and bromine to (Z)-1,2-diphenylethene (cis-stilbene) in the presence of different solvents, such as glacial acetic acid and dichloromethane. Bromine in glacial acetic acid gave an acceptable yield of d,l-1,2-dibromo-1,2-diphenylethane (d,l-DBDPE) than does PBPB in glacial acetic acid, and that even bromine in dichloromethane yields about 45% of d,l-DBDPE. A 49% of the d,l product was recovered by evaporating completely the dichloromethane.

UV and CD spectra have been measured for several α-substituted succinic anhydrides and imides. The Cotton effect signs corresponding to the two n-π* electronic transitions can be explained with the octant rule. The strong substituent and solvent dependence of the spectra is a result of the equilibrium between two skewed conformers of the five-membered ring. The geometry and relative energies of the conformers were found from mol. mechanics (MM2) calculations

Yin, Jiameng; Lin, Yajun; Fang, Weiwei; Zhang, Xin; Wei, Jie; Hu, Gang; Liu, Pu; Niu, Jie; Guo, Jun; Zhen, Yongzhan; Li, Jian published the artcile< Tetrandrine citrate suppresses breast cancer via depletion of glutathione peroxidase 4 and activation of nuclear receptor coactivator 4-mediated ferritinophagy>, Application In Synthesis of 347174-05-4, the main research area is tetrandrine citrate glutathione peroxidase nuclear receptor coactivator breast cancer; breast cancer; ferroptosis; glutathione peroxidase 4; nuclear receptor coactivator 4; tetrandrine citrate.

Tetrandrine citrate (TetC), a novel tetrandrine salt with high water solubility, demonstrates a potent antitumor activity in chronic myeloid leukemia. Studies have indicated an important role of ferroptosis in breast cancer (BC). However, whether TetC inhibits BC progression via ferroptosis has never been explored. In the present study, we showed that TetC had a significant inhibitory effect on the proliferation and migration of MCF7 and MDA-MB-231 cells. Then, we combined TetC with different inhibitors to determine which form of cell death could be driven by TetC. MTT assay showed that ferrostatin (Fer-1) demonstrated the most potent effect on improving TetC-induced cell death in contrast to other inhibitors. TetC was also shown to significantly increase the mRNA level of prostaglandinendoperoxide synthase 2 (Ptgs2), a ferroptosis marker. Further studies showed that TetC significantly suppressed the expression of glutathione peroxidase 4 (GPX4) and ferritin heavy chain 1 (FTH1) but increased the expression of nuclear receptor coactivator 4 (NCOA4) in MCF7 and MDA-MB-231 cells even in the presence of erastin or Ras-selective lethal 3 (RSL3). Collectively, we showed novel data that ferroptosis was a major form of TetC-induced cell death. Moreover, TetC-induced ferroptotic cell death was achieved via suppressing GPX4 expression and activating NCOA4-mediated ferritinophagy in BC cells.
