Expanding Access to Remdesivir via an Improved Pyrrolotriazine Synthesis: Supply Centered Synthesis

Pyrrolotriazine 1 is an important precursor to remdesivir. Initial results toward an efficient synthesis are disclosed consisting of sequential cyanation, amination, and triazine formation beginning from pyrrole. This route makes use of highly abundant, commoditized raw material inputs. The yield of triazine was doubled from 31% to 59%, and the synthetic step count was reduced from 4 to 2. These efforts help to secure the remdesivir supply chain.

Application of 155899-66-4, The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 155899-66-4 is helpful to your research.

Elevated CO2 improves glucosinolate metabolism and stimulates anticancer and anti-inflammatory properties of broccoli sprouts

Sprouting process enhances plant bioactive compounds. Broccoli (Brassica oleracea L) sprouts are well known for their high levels of glucosinolates (GLs), amino acids, and antioxidants, which offer outstanding biological activities with positive impacts on plant metabolism. Elevated CO2 (eCO(2), 620 ppm) was applied for 9 days to further improve nutritive and health-promoting values of three cultivars of broccoli sprouts i.e., Southern star, Prominence and Monotop. eCO(2) improved sprouts growth and induced GLs accumulation e.g., glucoraphanin, possibly through amino acids production e.g., high methionine and tryptophan. There were increases in myrosinase activity, which stimulated GLs hydrolysis to yield health-promoting sulforaphane. Interestingly, low levels of ineffective sulforaphane nitrile were detected and positively correlated with reduced epithiospecifier protein after eCO(2) treatment. High glucoraphanin and sulforaphane levels in eCO(2) treated sprouts improved the anticarcinogenic and anti-inflammatory properties of their extracts. In conclusion, eCO(2) treatment enriches broccoli sprouts with health-promoting metabolites and bioactivities.

Regioselective Transition-Metal-Free Synthesis of 2-(Trimethylsilylmethylene)pyrrol-3-ones by Thermal Cyclization of Acetylenic Enamines

Acetylenic enamines generated in situ from readily available enynones and primary amines undergo thermal cyclization in diphenyl ether providing easy access to 4-aryl-2-(trimethylsilylmethylene)-1,2-dihydro-3H-pyrrol-3-ones. This reaction is inherently versatile, allowing for variations of substituents in both enynone and amine. Full regioselectivity along with short reaction time (1-2 h) and simple workup afford single products in good to excellent isolated yields. Fluorescent properties of the obtained compounds were studied.

Formation of 3-pyrrolin-2-one or imidazolidine derivatives by slow dimerization of N-substituted aziridine-2-carboxylates

Prolonged storage (45-60 days) of N-methyl- or N-cyclopropylaziridine-2-carboxylates leads to their dimerization through the N-C(3) bond cleavage to form 1,3-disubstituted 2-methylimidazolidine-2,4-dicarboxylates in high yields. Prolonged storage of 1-benzylaziridine-2-carboxylate (like the reactions of alkyl pyruvates with primary amines) results in cyclocondensation to yield 3-pyrrolin-2-one derivative.

Organocatalyzed Asymmetric Mannich Reaction: An Update

The Mannich reaction is a multicomponent reaction resulting in aminoalkylation of an acidic proton placed next to a carbonyl functional group. It involves an appropriate carbonyl compound, such as formaldehyde and a primary or secondary amine or ammonia. The final product is a beta-amino-carbonyl compound known as a Mannich base. Reactions between aldimines and alpha-methylene carbonyls are also considered as Mannich reaction since these imines are generated from the reaction of amines and aldehydes. It comprises the reaction of primary or secondary amines or ammonia, formaldehyde and appropriate alpha-CH-acidic compounds (nucleophiles) such as carbonyl compounds having alpha-CH-acidic, nitriles, acetylenes, aliphatic nitro compounds, alpha-alkyl-pyridines or imines. Owing to the development of asymmetric organocatalysis, reports on asymmetric Mannich reaction have been drastically increased. The asymmetric Mannich reaction offers access to enantioenriched beta-amino ketones or beta-amino aldehydes, which are present as a scaffold in several natural products. Organocatalysts have been developed not only as a supplement to metal-catalyzed reactions or to biocatalysis, but nowadays, they are extensively used for the synthesis of various optically pure compounds that could not be achieved via metal- or biocatalyzed reactions. In this review, we try to update the advances in organocatalyzed asymmetric Mannich reactions, covering the recent advances of the subject from 2008 to date.

Synthesis and study of new 5-substituted 1-acetyl-4-phenyl-3-pyrrolin-2-ones as potential antitumor agents

The treatment of 1-acetyl-5-bromo-4-phenyl-3-pyrrolin-2-one with appropriate silver salts in benzene promotes the substitution of bromine with chloride, fluoride, nitrite, nitrate, and thiocyanate groups. Biological testing of the newly synthesized compounds resulted in the discovery of moderate indoleamine 2,3-dioxygenase and matrix metalloproteinase inhibiting properties for NO2 and SCN derivatives in combination with low antitumor effect in vivo. However, testing of the NO2 derivative in mice with transplanted 4T1 mammary and CT-26 mouse colon carcinomas led to a considerable decrease in tumor volume and lung metastases without undesirable toxic effects evidencing potent tumor supressing properties.

NMR spin trapping: Detection of free radical reactions using a phosphorus-containing nitrone spin trap

This study employs P-31-nuclear magnetic resonance (NMR) to probe for changes in molecular structure arising from reactions between free radicals and a phosphorus-containing nitrone spin trap, 5-diethoxyphosphoryl-5-methyl-1-pyrroline-N-oxide (DEPMPO), A number of biologically relevant free radical reactions were detected: a) reactions of DEPMPO with OH resulted in a new P-31-NMR resonance at 27.05 ppm (shifted from the parent compound at 23.67 ppm); evidence suggests that this species is a diamagnetic hydroxy-pyrrolidone reduction product; b) P-31-NMR spectra of DEPMPO/(CH3)-C-. reactions resulted in peaks at 24.54, 30.83, and 32.31 ppm, while DEPMPO/(CH2OH)-C-. produced peaks at 24.05, 30.80 and 32.52 ppm; in the presence of excess ascorbate, only resonances between 30 and 32 ppm were evident, which we have tentatively assigned to the hydroxylamine isomers of their respective adducts; and c) reaction of DEPMPO with O-2(.-), produced by xanthine/xanthine oxidase or stimulated neutrophils, resulted in a single line, indistinguishable from DEPMPO/(OH)-O-. reaction products, We conclude that NMR spin trapping is a useful approach for detecting free radical reaction pathways. It may have future applications for human free radical biology and imaging. Magn Reson Med 42:228-234, 1999. (C) 1999 Wiley-Liss, Inc.
