Chemistry is traditionally divided into organic and inorganic chemistry. 3190-70-3, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 3190-70-3

Due to its relevance in the synthesis of well-defined oligopeptides, the L-leucine-N-carboxyanhydride (leucine-NCA) synthesis was selected for fine chemical scale-up with a scope on application on larger scales. The heterogeneous gas-solid-liquid nature of the leucine-NCA synthesis implied a mass transfer limited reaction rate towards phosgenation and was investigated on bench scale. Upon scale increase, the liquid-gas mass transport of HCl is drastically reduced, retarding the reaction and consequently rendering the process unsuitable for scale-up. Addition of an HCl scavenger such as (+)-limonene prevented side reactions thus allowing a cost reduction, a considerably faster reaction, and minimization of the amount of phosgene source used. The modified leucine-NCA synthesis has successfully been made scalable, maintaining high product purity on a 1.0 dm3 scale.

Helicobacter pylori is a Gram-negative bacterium that colonizes the gut of over 50% of the worlds population. It is responsible for most peptic ulcers and is an important risk factor for gastric cancer. Antibiotic treatment for H. pylori infections is challenging as drug resistance has developed to antibiotics with traditional mechanisms of action. H. pylori uses an unusual pathway for menaquinone biosynthesis with 5?-methylthioadenosine/S-adenosylhomocysteine nucleosidase (MTAN) catalyzing an essential step. We validated MTAN as a target with a transition-state analogue of the enzyme [Wang, S.; Haapalainen, A. M.; Yan, F.; et al. Biochemistry 2012, 51, 6892-6894]. MTAN inhibitors will only be useful drug candidates if they can both include tight binding to the MTAN target and have the ability to penetrate the complex cell membrane found in Gram-negative H. pylori. Here we explore structural scaffolds for MTAN inhibition and for growth inhibition of cultured H. pylori. Sixteen analogues reported here are transition-state analogues of H. pylori MTAN with dissociation constants of 50 pM or below. Ten of these prevent growth of the H. pylori with IC90 values below 0.01 mug/mL. These remarkable compounds meet the criteria for potent inhibition and cell penetration. As a consequence, 10 new H. pylori antibiotic candidates are identified, all of which prevent H. pylori growth at concentrations 16-2000-fold lower than the five antibiotics, amoxicillin, metronidazole, levofloxacin, tetracyclin, and clarithromycin, commonly used to treat H. pylori infections. X-ray crystal structures of MTAN cocrystallized with several inhibitors show them to bind in the active site making interactions consistent with transition-state analogues.

What a catch! Basic ionic liquids (ILs) based on a phosphonium hydroxide derivative can be tuned for CO2 capture by varying the weak proton donors, which have different pKa values. The stability, absorption capacity, and absorption enthalpy of the ILs could be easily tuned: the best IL for CO2 capture has good stability (>300 C), energy saving (ca. 56kJ mol-1), and equimolar absorption capability.

Introduction: Fenfluramine (3?trifluoromethyl?N?ethylamphetamine), a former anorectic agent, has been successfully repurposed for Dravet syndrome (DS). Area covered: A systematic review of data on fenfluramine in the treatment of patients with DS has been conducted, with 11 published papers on the use of fenfluramine for DS (six clinical trials, of which two were randomized controlled trials (RCTs), and five preclinical studies). Following clinical observations suggesting the efficacy of fenfluramine, the effect on convulsive seizures has been confirmed by two RCTs. The first RCT demonstrated the efficacy of the two tested doses of 0.2 mg/kg/day and 0.7 mg/kg/day, while the second RCT showed the efficacy of 0.4 mg/kg/day fenfluramine in patients with DS treated with stiripentol. Expert opinion: Preclinical studies provide insights into the mechanisms of action of fenfluramine. There are still no large real-life studies. Fenfluramine is under investigation for the treatment of other epilepsy syndromes.

A pilot plant campaign was performed to study MEA degradation in CO2 capture conditions and anticipate potential degradation products emissions to the atmosphere in industrial case. Aqueous 30% wt MEA was cycled between absorption and regeneration steps during 1700 h in the presence of a synthetic flue gas containing 81% of N2, 14% of CO2, 5% of O2, 97 ppm of NO, 9 ppm of SO2 and 5 ppm of NO2. Specific methods (sampling, sample conditioning and analysis) were developed to improve degradation products identification and to provide a quantification of targeted compounds in liquid phase and above all in absorber and stripper gas effluents. Especially, trace elements were detected in liquid phase thanks to Head Space-Solid Phase MicroExtraction (HS-SPME) and liquid-liquid extraction with ChemElut cartridges and in gas phase thanks to adsorbent tubes of different type: Sep-Pak for aldehydes and ketones, Orbo 60 for N-nitrosodimethylamine, Tenax and active charcoal for non-specific adsorption. 32 degradation products were identified in liquid phase and 38 in gas phase, 17 of which for the first time, especially derivatives of pyridine and oxazolidine, 1H-pyrrole and a new nitrosamine, the N-nitroso-2-methyl-oxazolidine.
