Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Formula: C10H12N2O4. Introducing a new discovery about 16082-13-6, Name is Diethyl pyridazine-3,4-dicarboxylate

A convenient route to prepare unsubstituted pyridazine-3,4-dicarboxylic acid on a preparative scale is described.The synthesis involves a hetero Diels-Alder reaction between a new 1,2-diaza-1,3-diene and ethyl vinyl ether and oxidation of the intermediate 1,4,5,6-tetrahydropyridazine as the key step.

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.Formula: C10H12N2O4, you can also check out more blogs about16082-13-6

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 20744-39-2, Pyridazin-4-amine, introducing its new discovery.

Antiviral drug resistance in influenza infections has been a major threat to public health. To develop a broad-spectrum inhibitor of influenza to combat the problem of drug resistance, we previously identified the highly conserved E339…R416 salt bridge of the nucleoprotein trimer as a target and compound 1 as an inhibitor disrupting the salt bridge with an EC50 = 2.7 muM against influenza A (A/WSN/1933). We have further modified this compound via a structure-based approach and performed antiviral activity screening to identify compounds 29 and 30 with EC50 values of 110 and 120 nM, respectively, and without measurable host cell cytotoxicity. Compared to the clinically used neuraminidase inhibitors, these two compounds showed better activity profiles against drug-resistant influenza A strains, as well as influenza B, and improved survival of influenza-infected mice.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Safety of 3-Phenyl-6-chloropyridazine. Introducing a new discovery about 20375-65-9, Name is 3-Phenyl-6-chloropyridazine

A library of iminolactones was prepared by esterification of several 2-hydroxyketones with a number of N-protected d- and l-alpha-amino acids. Some of the hydroxyketones were of terpenoid origin while others were obtained via synthesis. After N-deprotection of the intermediate esters, the free amines spontaneously underwent condensation with the ketone to form iminolactones. Esters of (1S,2S,5S)-2-hydroxypinan-3-one with both d- and l-alpha-amino acids were partially epimerized at the alpha-carbon atom to give a diastereomeric ester mixture. Only iminolactones of l-amino acids were formed after cyclization of (1S,2S,5S)-2-hydroxypinan-3-one, and correspondingly only d-amino acid iminolactones were formed after reaction with (1R,2R,5R)-2-hydroxypinan-3-one. The protocol thus enables inversion of the absolute configuration of amino acids. Some members of the prepared library of iminolactones displayed significant anti-proliferative effects toward three cancer cell lines (EL4, MCF7, PC3) with insignificant effect on non-malign cell lines (McCoy, MCF10A, NIH3T3). Thus, iminolactones appear to be potential lead structures for preparation of drugs selectively affecting proliferation of malign cell lines.

The reaction of thiocarbonyl fluoride, generated from difluorocarbene, with various amines under mild conditions is described. Secondary amines, primary amines, and o-phenylenediamines are converted to thiocarbamoyl fluorides, isothiocyanates, and difluoromethylthiolated heterocycles, respectively. Thiocarbamoyl fluorides were further transformed into trifluoromethylated amines by using a one-pot process. Thiocarbonyl fluoride is generated in situ and is rapidly fully converted in one pot under mild conditions; therefore, no special safety precautions are needed.

In the 2(2H)-one series, the reactions of 2b with various amino compounds resulted in various types of products. The reaction of N-methylaminopyridazines 1g,h with DMAD led to the endo-N-substituted derivatives 8a,b, whereas 1h with diethyl ethoxymethylenemalonate (DEM) gave the exo-N-substituted compound 1k. The constitution of the compounds was proved by spectroscopic and chemical evidences.
