Novel N-(benzothiazol/oxazol-2-yl) 2 [(5-(phenoxymethyl)-4-aryl-4H-1,2,4-triazol-3-yethio] acetamide derivatives (5a-n) were synthesized and investigated for in vitro anti-inflammatory activity and p38 alpha MAP kinase inhibition. Compounds showing good in vitro activities (5a, 5b, 5d, 5e, 5i, 5k and 5l) were studied for their in vivo anti-inflammatory activity using carrageenan induced rat paw edema model. Compound 5b emerged as the most active compound with an edema inhibition of 84.43%. It also showed improved GI safety profile with lower ulcer severity index and lipid peroxidation potential. Also, p38 alpha MAP kinase assay of 5b showed superior inhibitory potency (IC50:0.031 +/- 0.14 mu M) than the standard SB 203580 (IC50:0.043 +/- 0.14 mu M). To predict their binding mode compounds were also docked against p38 alpha MAP kinase enzyme. Compound 5b and SB 203580 showed hinge region interaction with MET 109.

New discoveries in chemical research and development in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 105832-38-0, Name is 2-(2,5-Dioxopyrrolidin-1-yl)-1,1,3,3-tetramethylisouronium tetrafluoroborate, molecular formula is C9H16BF4N3O3. In an article, author is Mamane, Victor,once mentioned of 105832-38-0, Recommanded Product: 2-(2,5-Dioxopyrrolidin-1-yl)-1,1,3,3-tetramethylisouronium tetrafluoroborate.

Asymmetric catalysis based on halogen and chalcogen bonds (XB and ChB) is in its infancy, and the search for new chiral XB and ChB donors represents a crucial step toward its development. In this context, we designed and prepared new motifs containing three key substructures: namely, regions of electron charge density depletion centered on iodine and chalcogen atoms, the ethynyl functionality, and the planar chiral ferrocenyl platform. Nine ferrocenyl iodoalkynes were prepared as pure enantiomers by asymmetric synthesis. The XB donor property of racemic ferrocenyl iodoalkynes was demonstrated in solution in two benchmark reactions: the Ritter reaction and the benzoxazole synthesis from thioamides. In contrast, the ferrocenyl chalcogenoalkynes were far less active in these reactions. The potential of racemic and enantiopure ferrocenyl iodoalkynes as XB donors was also confirmed by X-ray diffraction analysis, showing I center dot center dot center dot C contacts between the electropositive u-hole of the iodine atom and electron-rich it clouds for all crystal structures studied in the solid state.

Amino functionalized boron nitride nanosheets (FBN) were incorporated into a crosslinked, thermally rearranged polyimide (XTR) to fabricate FBN-XTR nanocomposite membrane. The FBN-XTR membrane exhibited a small decrease in H-2 permeability but demonstrated a remarkably increased H-2 gas selectivity over other gases, compared with XTR. The XTR membrane heat-treated at 425 degrees C had a H-2 permeability of 210 Barrers and a H-2/CH4 separation factor of 24.1, whereas the nanocomposite membrane with 1 wt% FBN exhibited a H-2 permeability of 110 Barrers and H-2/CH4 separation factor of 275, an order of magnitude greater. At 1wt% FBN loading, the FBN-XTR membrane showed three times higher tensile strength and 60% higher elongation than pristine XTR membrane. In addition, FBN-XTR was found to be able to be readily processed into thin-film membranes for practical H-2 separation applications.

New discoveries in chemical research and development in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 2892-51-5, Name is 3,4-Dihydroxy-3-cyclobutene-1,2-dione, molecular formula is C4H2O4.

alpha-Glucosidase is known to catalyze the digestion of carbohydrates and release free glucose into the digestive tract. Protein tyrosine phosphatase 1B (PTP1B) is engaged in the dephosphorylation of the insulin receptor and regulation of insulin sensitivity. Therefore, dual antagonists by targeting both -glucosidase and PTP1B may be potential candidates for type 2 diabetes therapy. In this work, three series of novel N-aryl–(benzoazol-2-yl)-sulfanylalkanamides were synthesized and assayed for their -glucosidase and PTP1B inhibitory activities, respectively. Compound 3l, exhibiting the most effective -glucosidase inhibitory activity (IC50=10.96m (3l), IC50=51.32m (Acarbose), IC50=18.22m (Ursolic acid)) and potent PTP1B inhibitory activity (IC50=13.46m (3l), IC50=14.50m (Ursolic acid)), was identified as a novel dual inhibitor of -glucosidase and PTP1B. Furthermore, 3l is a highly selective PTP1B inhibitor because no inhibition was showed by 3l at 100m against PTP-MEG2, TCPTP, SHP2, or SHP1. Subsequent kinetic analysis revealed 3l inhibited -glucosidase in a reversible and mixed manner. Molecular docking study indicated that hydrogen bonds, van der Waals, charge interactions and Pi-cation interactions all contributed to affinity between 3l and -glucosidase/PTP1B.

Following on from ezutromid, the first-in-class benzoxazole utrophin modulator that progressed to Phase 2 clinical trials for the treatment of Duchenne muscular dystrophy, a new chemotype was designed to optimise its physicochemical and ADME profile. Herein we report the synthesis of SMT022357, a second generation utrophin modulator preclinical candidate, and an asymmetric synthesis of its constituent enantiomers. The pharmacological properties of both enantiomers were evaluated in vitro and in vivo. No significant difference in the activity or efficacy was observed between the two enantiomers; activity was found to be comparable to the racemic mixture. (C) 2019 The Authors.

When, cyanothioformamide derivatives are reacted with certain electrophiles, they produce imidazole, oxazole, thiazole, 2,5-thiadiazole, bis-imidazole and bis-oxazole derivatives; while the reaction with certain nucleophiles furnish benzoxazole, quinaolinone, triazole, bis-triazole, benzoxazinethione and 1,3,4-thiadiazole derivatives. Imidazolidineiminothione derivatives were obtained by ring closure reaction of cyanothioformamide derivatives with isocyanates. These reactions give rise to imidazole derivatives that contain adjacent thione and imino functional groups in the positions 4 and 5 which are reactive in numbers of subsequent ring closure reactions. These compounds find applications as medicinal and pharmacological agents.
