Binding motif of ebselen in solution: chalcogen and hydrogen bonds team up

Ebselen (2-phenyl-1,2-benzoselenazol-3(2H)one), a glutathione peroxidase mimic, is active against several RNA viruses, among others the retrovirus responsible for the COVID-19 pandemic. In this paper Se-77 and H-1 NMR studies of ebselen are reported and they identify the chalcogen bond (ChB) and hydrogen bond (HB) that are central in the landscape of interactions formed by the compound in solution. The selenium atom and the hydrogen atom at the C7 carbon act as ChB and HB donors and the O and N atoms of neutral molecules function as acceptors. The ChB and HB give rise to a bifurcated supramolecular synthon, which fastens the interaction acceptor opposite to the N-Se covalent bond of the selenazole ring. It is known that the biologically important reaction of ebselen with cysteine thiol groups is favoured when selenium acts as a chalcogen bond donor.

Toward a treatment of diabesity: Rational design, synthesis and biological evaluation of benzene-sulfonamide derivatives as a new class of PTP-1B inhibitors

Targeting of protein tyrosine phosphatase-1B (PTP1B) has emerged as a promising strategy for therapeutic intervention of diabetes and obesity. Investigation of new inhibitors with good bioavailability and high selectivity is the major challenge of drug discovery program targeting PTP1B. Therefore, herein, new neutral benzenesulfonamide containing compounds were designed, synthesized and biologically evaluated as potent PTP1B inhibitors. New series of thiazolidine, oxazolidine, thiazinan, oxazinan, oxazole, thiazole, tetrazole, cyanopyridine, chromenone, and iminochromene of benzene-sulfonamide derivatives (MSE-1 to MSE-15) were synthesized in a good yield under mild condition using sulfadiazine as a starting material. Among the synthesized compounds, MSE-13 and MSE-14 showed the most in vitro potent PTP-1B inhibitory activity (IC50 of 0.88 mu M and 3.33 mu M, respectively). Animal treatment by the target compounds significantly improved the insulin resistance, diminished plasma glucose level, decreased initial body weight, and normalized the serum lipid profile compared to pioglitazone, a standard PTP1B inhibitor. The molecular modeling study showed a high affinity and selectivity of our synthesized compounds to the active site and B-site of PTP1B holding hydrogen bonding, hydrophobic, and electrostatic interactions. Furthermore, Electrostatic Surface Potential (ESP) and HOMO/LUMO analysis indicated the importance of sulfamoyl moiety for PTP1B binding. In silico ADME predictions of such compounds also showed the promising pharmacokinetic and physicochemical properties. The proposed compounds could be considered a lead inhibitory scaffold to PTP1B.

Diastereoselective alkylation reactions employing a new camphor-based 2-phenylimino-2-oxazolidine chiral auxiliary

A new camphor-based 2-phenylimino-2-oxazolidine chiral auxiliary was prepared and it was shown to be a particularly effective chiral auxiliary for asymmetric alkylations affording high yields and diastereoselectivities. The alkylation products were readily cleaved by simple alkaline hydrolysis to give alpha-alkylated carboxylic acids in good yield and in almost enatiomerically pure form. (C) 2014 Jun-Qi Nie.

Microwave-Assisted Improved Synthesis of Oxazolidin-2-ones, Oxazolidine-2-thiones and Thiazolidine-2-thione Chiral Auxiliaries

A microwave assisted method for the synthesis of some typical 4-substituted oxazolidinone chiral auxiliaries used in asymmetric synthesis is reported in this work. Under these conditions, treatment of (S)-phenylalaninol, (S)-phenylglycinol, (S)-valinol and (1S, 2R)-norephedrine with ethyl carbonate or carbon disulfide under the appropriate and specific microwave reaction conditions, led to an efficient synthesis of some oxazolidin-2-ones, oxazolidine-2-thiones and thiazolidine-2-thiones. The methodology reported in this paper provides these chiral auxiliaries with improved yields and a remarkable reduction on the reaction times, particularly in the case of thiazolidine-2thiones, as compared with the conventional methods. All the auxiliaries prepared here show spectroscopic data in full agreement with those previously reported in the literature.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 99395-88-7, in my other articles.

Racemic mefloquinium chlorodifluoroacetate: crystal structure and Hirshfeld surface analysis

In the racemic title molecular salt, C17H17F6N2O+center dot C2ClF2O3-(systematic name: 2-{[2,8-bis(trifluoromethyl) quinolin-4-yl](hydroxy) methyl} piperidin-1-ium chlorodifluoroacetate), the cation, which is protonated at the piperidine N atom, has the shape of the letter, L, with the piperidin-1-ium group being approximately orthogonal to the quinolinyl residue [the C-q-C-m-C-m-N-a (q = quinolinyl; m = methine; a = ammonium) torsion angle is 177.79 (18)degrees]. An intramolecular, charge-assisted ammonium-N-H center dot center dot center dot O(hydroxyl) hydrogen bond ensures the hydroxy-O and ammonium-N atoms lie to the same side of the molecule [O-h-C-m-C-m-N-a (h = hydroxyl) = -59.7 (2)degrees]. In the crystal, charge-assisted hydroxyl-O-H center dot center dot center dot O- (carboxylate) and ammonium-N+-H center dot center dot center dot O-(carboxylate) hydrogen bonds generate a supramolecular chain along [010]; the chain is consolidated by C-H center dot center dot center dot O interactions. Links between chains to form supramolecular layers are of the type C-Cl center dot center dot center dot pi (quinolinyl-C-6) and the layers thus formed stack along the a-axis direction without directional interactions between them. The analysis of the calculated Hirshfeld surface points to the dominance of F center dot center dot center dot H contacts to the surface (40.8%) with significant contributions from F center dot center dot center dot F (10.5%) and C center dot center dot center dot F (7.0%) contacts.

Crystal structure and magneto-structural investigation of alkoxido bridged dinuclear Fe(III) complexes with 1,3-oxazolidine ligands

Four 1,3-oxazolidine based ligands (H2L1-H2L4) were synthesized in solvent-free condition from the reaction of amino alcohols (2-amino-2-(hydroxymethyl)-1,3-propanediol or 2-amino-2-ethy1-1,3-propanediol) and 2-acetylpyridine or 2-pyridinecarboxaldehyde at 110 T. Four new dinuclear Fe(III) complexes, [Fe-2(HL1)(N-3)(4)] (1), EFe2(HL2)(N-3)(4)] (2), [Fe-2(HL3)(N-3)(4)] (3) and [Fe-2(HL4)(N-3)(4)] (4), were synthesized with a similar procedure by the reaction of H2L1-4, Fe(NO3)(3).9H(2)O and NaN3 in 1:1:2 molar ratios in methanol. The ligands and complexes were characterized by elemental analysis and spectroscopic methods. The structure of complexes was solved by single-crystal X-ray diffraction analysis which showed complexes 1-4 to be alkoxido-bridged dinuclear Fe(III) complexes. The structural studies indicated that the crystal structure of 2, 3 and 4 consist of a centrosymmetric dinuclear Fe(III) complexes while the asymmetric unit in 1 consists of two halves of the two independent molecules. The Fe(III) ions have similar coordination environments (cis-FeN4O2) in all of 1-4 which can be described as distorted octahedral geometry. The 1,3-oxazolidine ligands act as mononegative tridentate N2O-donor ligand in 1-4. Two azide groups are also coordinated to each Fe(III) ion as terminal monodentate ligands. The alcoholic arms of the 1,3-oxazilidine ligands act as bridging groups between Fe(III) ions and the Fe center dot center dot center dot Fe distances through these bridges are in the range of 3.157-3.198 A. Magnetic studies in 2-300 K range reveal antiferromagnetic interactions between the Fe(III) ions with values for the magnetic coupling constants in the range -9.4 cm(-1) to -9.7 cm(-1), with H =-2(f)(S1S2) (C) 2019 Elsevier Ltd.

Crystal structure of 5-chloro-1,3-bis[2-(2oxo-1,3-oxazolidin-3-yl)ethyl]-1H-benz-imidazol-2(3H)-one

In the title compound, C17H19ClN4O5, the benzimidazole fused -ring system is essentially planar, the maximum deviation from the mean plane being 0.06 (1) angstrom. Both oxazolidine rings are nearly planar, the maximum deviations from the mean planes are 0.071 (13) and 0.070 (10) angstrom. The dihedral angle between the mean planes of the oxazolidine rings is 69.9 (7). The benzimidazole mean plane makes the dihedral angles of 43.9 (6) and 45.6 (6)degrees with the two oxazolidine rings. In the crystal, the molecules are linked together by weak C-H center dot center dot center dot O hydrogen bonds building zigzag tapes running along the c axis. The Cl atom is split over two positions with an occupancy ratio of 0.567 (7):0.433 (7). This means that the reaction yields two isomers, A and B; the A component has the Cl-atom substituent in the 5-position of the benzimidazolone ring and the B component has the Cl atom in the 6 -position. The two isomers form the disordered co-crystal, with a nearly half Cl atom in each of them, as indicated by the occupancy ratio. The crystal structure was refined as an inversion twin.

Nutrient composition, glucosinolate and vinyl-oxazolidine-thione profiling of Indian rapeseed (Brassica juncea Coss.) meal

Presence of antinutritional factor(s) in any feedstuff impedes effective nutrient utilization by animals, besides causing specific adverse effects. This study includes eighteen different batches of Indian rapeseed (Brassica juncea Coss.) meal (RSM) sampled over a period of nine months for their evaluation in terms of nutrient composition, glucosinolate (GL) and vinyl-oxazolidine-thione (VOT) concentrations. Results showed that RSM contained a mean value (on dry basis) of crude protein (36.7%), ether extract (1.1%), ash (7.6%), crude fibre (10%), neutral detergent fibre (25%), acid detergent fibre (16.5%), hemicellulose (8.6%), total carbohydrates (54.7%), non-fibrous carbohydrates (29.7%), total digestible nutrients (77.9%) and metabolizable energy (11.7 MJ/kg). Furthermore, antinutritional factors like GL (mu mol/g) and VOT (mg/g) are presented to be in the range of 36.2-72.2 (mean: 52) and 0-3.2 (mean: 1.0) respectively. Based on the species-wise tolerance limit for GL, the optimum inclusion level of RSM recommended for ruminants, pigs, rabbits, rats, poultry and fish is 15.6%, 1.5%, 13.5%, 1%, 10.4% and 6.9% respectively. Results of the present study are expected to maximize precision ration balancing for enhanced nutrient utilization whilst also curtailing any possible adverse effects of GL and VOT on production performance of animals.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 16251-45-9. HPLC of Formula: C10H11NO2.
