Dugar, Sundeep; Hollinger, Frank P.; Kuila, Bilash; Arora, Reena; Sen, Somdutta; Mahajan, Dinesh published their research in Bioorganic & Medicinal Chemistry Letters on August 15 ,2015. The article was titled 《Synthesis and evaluation of pyrrolotriazine based molecules as PI3 kinase inhibitors》.Product Details of 1190423-36-9 The article contains the following contents:

Over activation of the PI3K/Akt/mTOR pathway is found in most cancer tumor types. Controlled regulation of this pathway using PI3K inhibitors can provide therapeutic significance in cancer treatment. Herein, we report the synthesis and evaluation of pyrrolotriazine based novel small mols. as pan-PI3K inhibitors. The SAR studies based on in vitro potency along with microsomal metabolic stability screening, identified one compound I as a preclin. lead found to be suitable for in vivo evaluation. The identified lead was also found to be a selective inhibitor of PI3K isoforms and mTOR when screened across a panel of 23 homologous kinases. The experimental part of the paper was very detailed, including the reaction process of tert-Butyl (tert-butoxycarbonyl)(5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-yl)carbamate(cas: 1190423-36-9Product Details of 1190423-36-9)

In 1968,Journal of Pharmaceutical Sciences included an article by Venturella, Vincent S.. Safety of 6-Methoxypyrimidine-2,4(1H,3H)-dione. The article was titled 《Selective acid-catalyzed hydrolyses of methoxysulfanilamidodiazines》. The information in the text is summarized as follows:

The dilute acid hydrolysis of 3-methoxy-6-sulfanilamidopyridazine and several methoxysulfanilamidopyrimidines was studied. Experiments show that in cases where an intermediate 2-pyrimidone is a possible postulation, further hydrolysis usually leads to the formation of sulfanilamide and the corresponding hydroxypyrimidine. A multistage route for the acidic degradation of 3-methoxy-6-sulfanilamidopyridazine, 2,4-dimethoxy-6-sulfanilamidopyrimidine, and 2-methylthio-4-methoxy-6-sulfanilamidopyrimidine is proposed. 26 references.

Maruyama, Tatsuya; Onda, Kenichi; Hayakawa, Masahiko; Matsui, Tetsuo; Takasu, Toshiyuki; Ohta, Mitsuaki published an article in European Journal of Medicinal Chemistry. The title of the article was 《Discovery of novel acetanilide derivatives as potent and selective β3-adrenergic receptor agonists》.Recommanded Product: 63155-11-3 The author mentioned the following in the article:

In the search for potent and selective human β3-adrenergic receptor (AR) agonists as potential drugs for the treatment of obesity and noninsulin-dependent (type II) diabetes, a novel series of acetanilide-based analogs were prepared and their biol. activities were evaluated at the human β3-, β2-, and β1-ARs. Among these compounds, 2-pyridylacetanilide, pyrimidin-2-ylacetanilide, and pyrazin-2-ylacetanilide derivatives exhibited potent agonistic activity at the β3-AR with functional selectivity over the β1- and β2-ARs. In particular, pyrimidin-2-ylacetanilide was found to be the most potent and selective β3-AR agonist with an EC50 value of 0.11 μM and no agonistic activity for either the β1- or β2-AR. In addition, these three compounds showed significant hypoglycemic activity in a rodent diabetic model. In the part of experimental materials, we found many familiar compounds, such as Ethyl 2-(pyrimidin-2-yl)acetate(cas: 63155-11-3Recommanded Product: 63155-11-3)

Ethyl 2-(pyrimidin-2-yl)acetate(cas: 63155-11-3) is a member of pyrimidine. Pyrimidine derivatives are an important class of N-heterocycles. They are well-known for their wide spectrum of promising biological activities such as antitumors, bactericidals, and fungicidal.Recommanded Product: 63155-11-3

In 2019,Journal of the American Chemical Society included an article by Fawcett, Alexander; Murtaza, Amna; Gregson, Charlotte H. U.; Aggarwal, Varinder K.. Computed Properties of C4H2Cl2N2. The article was titled 《Strain-Release-Driven Homologation of Boronic Esters: Application to the Modular Synthesis of Azetidines》. The information in the text is summarized as follows:

Azetidines are important motifs in medicinal chem., but there are a limited number of methods for their synthesis. Herein, the authors present a new method for their modular construction by exploiting the high ring strain associated with azabicyclo[1.1.0]butane. Generation of azabicyclo[1.1.0]butyl lithium followed by its trapping with a boronic ester gives an intermediate boronate complex which, upon N-protonation with acetic acid, undergoes 1,2-migration with cleavage of the central C-N bond to relieve ring strain. The methodol. is applicable to primary, secondary, tertiary, aryl, and alkenyl boronic esters and occurs with complete stereospecificity. The homologated azetidinyl boronic esters can be further functionalized through reaction of the N-H azetidine, and through transformation of the boronic ester. The methodol. was applied to a short, stereoselective synthesis of the azetidine-containing pharmaceutical, cobimetinib. After reading the article, we found that the author used 2,4-Dichloropyrimidine(cas: 3934-20-1Computed Properties of C4H2Cl2N2)

2,4-Dichloropyrimidine(cas: 3934-20-1) is a member of organic chlorides. Almost all organochlorine compounds are synthesized. It is widely used as intermediates, solvents and pesticides of chemical synthetic products.Computed Properties of C4H2Cl2N2
