Calcitonin gene-related peptide (CGRP) receptor antagonists: Novel aspartates and succinates

Novel aspartate and succinate CGRP full antagonists were identified through core modification of a potent lead CGRP antagonist, BMS-694153. While aspartates were much less active and had a flat SAR, some of the succinates were very potent CGRP full antagonists and matched the potency of BMS-694153. The most potency resides in the S enantiomer as demonstrated through an asymmetric synthesis.

NOx reduction using amine reclaimer wastes (ARW) generated in post combustion CO2 capture

Amine reclaimer wastes (ARW) generated in CO2 capture processes demand suitable disposal means. Such wastes contain remaining amine, NH3 and other degradation compounds. This study investigated the potential of using ARW as a NOx reducing agent, under laboratory conditions in a flow reactor. A simulated flue gas containing about 500ppm of NO and 5% O2 was injected with liquid ARW under different stoichiometric ratios (TN/NO – total N to nitric oxide ratio) and temperatures. The ARW was obtained from a distillation monoethanolamine reclaimer in an industrial CO2 capture facility with a coal fired boiler. The results indicate that ARW has a significant NOx reduction potential when injected with TN/NO ratios in excess of 1. The optimum temperature is close to 950C, where 40% reduction in NOx is recorded with a TN/NO ratio of 1.6. Increasing TN/NO to 8.5 resulted in a 96% reduction. At low TN/NO ratios (<1.6), the NOx reduction potential of ARW is comparable to that of monoethanolamine, but lower than that of NH3. Nevertheless, the fact that ARW is a waste product, together with its demonstrated NOx reduction capability and its calorific value contribution, makes it attractive as an additive to combustion processes, including cement industry kilns.

Ionic liquids/ZnO nanoparticles as recyclable catalyst for polycarbonate depolymerization

A useful protocol for waste bis-phenol A-polycarbonates (BPA-PC) chemical recycling is proposed based on a bifunctional acid/basic catalyst composed by nanostructured zinc oxide and tetrabutylammonium chloride (ZnO-NPs/NBu4Cl) in quality of Lewis acid and base, respectively. Retro-polymerization reaction proved to be of general application for several nucleophiles, including water, alcohols, amines, polyols, aminols and polyamines, leading to the complete recovery of BPA monomer and enabling the PC polymer to function as a green carbonylating agent (green phosgene alternative) for preparing carbonates, urethanes and ureas. A complete depolymerization can be obtained in seven hours at 100 C and ZnO nanocatalyst can be recycled several times without sensible loss of activity. Remarkably, when polycarbonate is reacted with glycerol, it is possible to realize in a single process the conversion of two industrial wastes (BPA-PC and glycerol) into two valuable chemicals like BPA monomer and glycerol carbonate (the latter being a useful industrial solvent and fuel additive).

Solvent extraction based reclaiming technique for the removal of heat stable salts (HSS) and neutral degradation products from amines used during the capture of carbon dioxide (CO2) from industrial flue gases

This work used a modified OH-aliquat mixed with a new diluent, namely, 2-ethyl-1-hexanol to separate heat stable salts (HSS), namely, formate, glycolate and oxalate as well as neutral degradation products (i.e. imidazole, N-acethylethanolamine, 2-oxazolidone, N-(2-hydroxyethyl)-succinimide) from monoethanolamine (MEA), 2-amino-2-methyl-1-propanol (AMP), and N-methyldiethanolamine (MDEA) and their blends which are amines/amine blends typically used for carbon dioxide (CO2) capture from industrial flue gases. The new diluent, which has a branched-chain structure, increased the extraction performance of the OH-aliquat up to 50% HSS removal from MEA solution compared to our previous straight-chained 1-octanol diluent. The extractant also performed very well in removing HSS from MDEA and AMP with the ease of HSS extraction increasing in the order of AMP < MEA < MDEA for which the oxalate was removed by nearly 100% regardless of the type of amine and concentration. In blended MEA, AMP and MDEA, the extractant had a higher chemical affinity in removing all HSS when compared with single MEA. The extractant could also remove major neutral degradation products found in MEA solution. High temperature and low CO2 loading conditions were found to be favorable in maximizing the ability of the extractant to remove both product types. This finding revealed that the exact location where the amine slipstream should be taken for simultaneous extraction of all degradation products is at the exit point of the lean-rich amine heat exchanger. The regeneration of extractant using sodium hydroxide solution (NaOH) also indicated the reusability of the extractant as long as its reactive molecules remained. The results obtained from this study are being used for further development of the extraction process that can be used as a permanent replacement for conventional reclaiming techniques. We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 497-25-6, and how the biochemistry of the body works.Related Products of 497-25-6

Design, synthesis and antitumor study of a series of N-Cyclic sulfamoylaminoethyl substituted 1,2,5-oxadiazol-3-amines as new indoleamine 2, 3-dioxygenase 1 (IDO1) inhibitors

Indoleamine 2, 3-dioxygenase 1 (IDO1) plays a key role in tryptophan catabolism which is an important mechanism in immune tolerance. The small molecule epacadostat is the most advanced IDO1 inhibitor, but its phase III trials as a single agent or in combinations with PD-1 antibody failed to show appreciable objective responses. To gain more insight on the antitumor efficacy of IDO1 inhibitors, we have designed a series of analogues of epacadostat by incorporating a cyclic aminosulfonamide moiety as the sidechain capping functionality. Compound 5a was found to display significant potency against recombinant hIDO1 and hIDO1 expressed HEK293 cancer cells. This compound has improved physico-chemical properties, acceptable PK parameters as well as optimal cardiac safety. Similar to epacadostat, 5a is ineffective as single agent in the CT-26 syngeneic xenograft model, however, the combination of 5a with PD-1 antibody showed both elevated tumor growth inhibition and prolonged median life span.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1192-07-0 is helpful to your research. Related Products of 1192-07-0

Asymmetric zinc-Reformatsky reaction of Evans chiral imide with acetophenones and its application to the stereoselective synthesis of triazole antifungal agents

The Ni(acac)2 catalytic ZnEt2-mediated asymmetric Reformatsky-type reaction of Evans chiral imide with various acetophenones was studied. The chiral imido zinc enolate, which was formed through the metal-halogen exchange reaction of chiral alpha-bromopropionyl-2-oxazolidinones 2 with diethyl zinc under the catalysis of Ni(acac)2, performed the asymmetric zinc-Reformatsky reaction with activated alpha-haloacetophenones 3 to give the chiral beta-hydroxyamide 4 in good yields and high ratios of syn-(2R,3R)-isomers (up to >97%). This new asymmetric synthesis technology affords a practical method to synthesize the versatile chiral building block 5 for triazole antifungal agents, such as Voriconazole, Ravuconazole, TAK-187, and RO-0094815.

Preparation of beta2-homotryptophan derivatives for beta-peptide synthesis

In view of the prominent role of the 1H-indol-3-yl side chain of tryptophan in peptides and proteins, it is important to have the appropriately protected homologs H-beta2-HTrp-OH and H-beta3-HTrp-OH (Fig.) available for incorporation in beta-peptides. The beta2-HTrp building block is especially important, because beta2-amino acid residues cause beta-peptide chains to fold to the unusual 12/10 helix or to a hairpin turn. The preparation of Fmoc- and Z-beta2-HTrp(Boc)-OH by Curtius degradation (Scheme 1) of a succinic acid derivative is described (Schemes 2 – 4). To this end, the (S)-4-isopropyl-3-[(N-Boc-indol-3-yl)propionyl]-1,3-oxazolidin-2-one enolate is alkylated with Br-CH2CO2Bn (Scheme 3). Subsequent hydrogenolysis, Curtius degradation, and removal of the Evans auxiliary group gives the desired derivatives of (R)-H-beta2-HTrp-OH (Scheme 4). Since the (R)-form of the auxiliary is also available, access to (S)-beta2-HTrp-containing beta-peptides is provided as well.
