In an article, author is Zheng, Jin-wen, introduce new discover of the category.

Block copolymer (BCP) nanoparticles with three different block sequences, PDMA-PNAT-PDAAM (M-N-D), PDMA-PDAAM-PNAT (M-D-N) and PDMA-P(NAT-co-DAAM) (M-[N-co-D]), are prepared via polymerization-induced self-assembly (PISA). Soluble N-acryloyloxy thiomorpholine (NAT) and diacetone acrylamide (DAAM) are used as monomers to form insoluble core blocks in water, while PDMA(35) bearing a trithiocarbonate is utilized as stabilizer and macromolecular chain transfer agent (macro-CTA) to render a RAFT control. Specifically, M-[N-co-D] nano-objects are synthesized via direct RAFT dispersion copolymerization of NAT and DAAM at 70 degrees C employing PDMA35 macro-CTA. To produce M-N-D and M-D-N triblock copolymers, PDMA-PNAT (M-N) and PDMA-PDAAM (M-D) nano-objects are prepared via RAFT dispersion PISA syntheses of NAT and DAAM respectively utilizing PDMA35 macro-CTA and then used for seeded dispersion polymerization of DAAM and NAT respectively without intermediate postpolymerization purification. The thioether moiety in NAT can be oxidized by reactive oxygen species (ROS) into a hydrophilic sulfoxide. Therefore, in the precense of hydrogen peroxide (H2O2), oxidation-responsive morphological degradation of these nano-objects occurs due to the increasing hydrophilicity of NAT units. Given the poor control over polymerization of NAT in pure water, 1,4-dioxane is used as a cosolvent to the PNAT block. So the PISA syntheses are conducted in water/1,4-dioxane (9/1, V/V) mixture to achieve a good control over the molecular weight and narrow distribution. H-1-NMR spectra indicate that quantitative monomer conversions (> 99%) are achieved within 5 h. Differential scanning calorimeter (DLS) and transmission electron microscopy (TEM) are used to characterize final morphologies of PISA-generated nano-objects and morphological evolution of nano-objects in the presence of H2O2 (10 mol/L). These aqueous sequence-controlled PISA formulations are expected to provide responsive nanoparticles with tunable kinetics due to the response-dependent morphological transitions, which may be potentially used as carriers for drug delivery and controlled release.

In a document, author is Soares Martins, Evandro Paulo, introduce the new discover.

Herein, we describe the synthesis and characterizations of 2,4,6-tris(thiomorpholine)-1,3,5-triazine, 2,4,6-tris(piperazine)-1,3,5-triazine and their new Sb(III) and Bi(III) complexes. Characterizations of the ligands and complexes were carried out by elemental analysis, thermogravimetric analysis (TGA), and spectroscopic methods such as infrared (IR), H-1 and C-13 nuclear magnetic resonance (NMR), and single crystal X-ray. Theoretical vibrational frequencies and H-1 and C-13 NMR chemical shifts of free ligands as well as their Sb(III) and Bi(III) complexes have been calculated using density functional theory (DFT/B3LYP and M06-2X) methods. Our theoretical results matched the corresponding experimental data and helped with the interpretation of the IR and H-1 and C-13 NMR spectra. The antimicrobial in vitro studies were carried out against bacterial species Staphylococcus aureus and fungal species Candida albicans, Candida tropicalis, and Candida krusei by the microdilution method. The preliminary antimicrobial evaluations indicated that Sb(III) complexes showed moderate activities against all tested strains of bacterial and fungal with minimum inhibitory concentration (MIC) in range of 512-1024 mu g mL(-1).

In an article, author is Krasheninina, Olga A., introduce new discover of the category.

We report a universal straightforward strategy for the chemical synthesis of modified oligoribonucleotides containing functional groups of different structures at the 2 ‘ position of ribose. The on-column synthetic concept is based on the incorporation of two types of commercial nucleotide phosphoramidites containing orthogonal 2 ‘-O-protecting groups, namely 2 ‘-O-thiomorpholine-carbothioate (TC, as permanent) and 2 ‘-O-tert-butyl(dimethyl)silyl (tBDMS, as temporary), to RNA during solid-phase synthesis. Subsequently, the support-bound RNA undergoes selective deprotection and follows postsynthetic 2 ‘ functionalization of the naked hydroxyl group. This convenient method to tailor RNA, utilizing the advantages of solid phase approaches, gives an opportunity to introduce site-specifically a wide range of linkers and functional groups. By this strategy, a series of RNAs containing diverse 2 ‘ functionalities were synthesized and studied with respect to their physicochemical properties.

A stability-indicating method for the determination of S-carboxymethyl-L-cysteine and related degradation impurities in Exputex (R) 250 mg/5 mL syrup was developed in anion-exchange liquid chromatography mode. A forced degradation study supported the method development to ensure stability indicating conditions. Aqueous solutions of the active pharmaceutical ingredient and syrup samples at different pH-values were stress-tested in different thermal, light exposure and headspace conditions. One degradation product was detected in thermal stress studies at 60 degrees C and 80 degrees C in the pH range 5.0-7.0 and was identified by mass spectrometry as 5-oxo-thiomorpholine-3-carboxylic acid (lactam of carbocysteine). A second degradation product was only generated in moderately strong oxidizing conditions (0.5% H2O2 aqueous solution) and was identified as S-carboxymethyl-L-cysteine-(R/S)-sulphoxide (carbocysteine sulphoxide). The method was developed on a Zorbax SAX column, in isocratic mode. The mobile phase consisted of 200 mM phosphate solution at pH 4.0 and acetonitrile (50:50 v/v) and UV detection was performed at a wavelength of 205 nm. The method was linear for carbocysteine (R > 0.9982) over a concentration range of 2.5-50 mu g/mL and 0.4-0.6 mg/mL. Linearity for the impurities was shown from the LOQ to 50 mu g/mL. Specificity was verified and accuracy demonstrated for the active ingredient and its degradation products in syrup samples at 3 levels around their respective specification limits. Repeatability, intermediate precision and inter-laboratory reproducibility were assessed on three commercial batches, analyzed in triplicate by two operators at both the transferring and the receiving site and demonstrated a successful method transfer to the manufacturing quality control laboratory.

In an article, author is Fernandes, Debra, once mentioned the application of 3965-55-7, Name is Sodium 3,5-bis(methoxycarbonyl)benzenesulfonate, molecular formula is C10H9NaO7S, molecular weight is 296.229, MDL number is MFCD00007493, category is thiomorpholine.

Carbamate formation is one of the major chemical reactions that can occur in solution in the capture of CO2 by amine-based solvents, and carbamate formation makes a significant enthalpy contribution to the absorption-desorption of CO2 that occurs in the absorber/stripper columns of the PCC process. Consequently, the formation of carbamates of selected series of primary and secondary amines over the temperature range (288 to 318) K has been investigated by equilibrium H-1 NMR studies, and the stability constants (K-9) for the equilibrium: RNH2 + HCO3- reversible arrow(K9) RNHCOO- + H2O are reported. van’t Hoff analyses have resulted in standard molar enthalpies, Delta H-m(o), and entropies, Delta S-m(o), of carbamate formation. A Delta H-m(o) – Delta S-m(o) plot generates a linear correlation for carbamate formation (providing a mean standard molar free energy, Delta G(m)(o), for carbamate formation of about -7 kJ . mol (1)), and this relationship helps provide a guide to the selection of an amine(s) solvent for CO2 capture, in terms of enthalpy considerations. A linear Delta H-m(o) – Delta S-m(o) plot also occurs for carbamate protonation. The formation of the carbamates has been correlated with systematic changes in composition and structure, and steric effects have been identified by comparing molecular geometries obtained using density functional B3LYP/6-311++G(d,p) calculations. Trends in steric effects have been identified in the series of compounds monoethanolamine (MEA), 1-amino-2-propanol, 2-amino-1-propanol (AP) and 2-amino-2-methyl-1-propanol (AMP). In the case of 2-piperidinemethanol, 2-piperidineethanol and 3-piperidinemethanol, strong intramolecular hydrogen bonding is shown to be the likely cause for lack of carbamate formation, and in the ring systems of pyrrolidine, morpholine, piperidine and thiomorpholine trends in carbamate formation (as given by K-9) have been correlated with the internal ring angle at the amine nitrogen, as well as the planarity of the environment around the nitrogen atom.
