Synthetic Route of C4H6N2On June 7, 2021, Alvarez, Eva Maria; Karl, Teresa; Berger, Florian; Torkowski, Luca; Ritter, Tobias published an article in Angewandte Chemie, International Edition. The article was 《Late-Stage Heteroarylation of Hetero(aryl)sulfonium Salts Activated by α-Amino Alkyl Radicals》. The article mentions the following:

We report a late-stage heteroarylation of aryl sulfonium salts through activation with α-amino alkyl radicals in a mechanistically distinct approach from previously reported halogen-atom transfer (XAT). The new mode of activation of aryl sulfonium salts proceeds in the absence of light and photoredox catalysts, engaging a wide range of heteroarenes. Furthermore, we demonstrate the applicability of this methodol. in synthetically useful cross-coupling transformations. In the experiment, the researchers used many compounds, for example, 1-Methylpyrazole(cas: 930-36-9Synthetic Route of C4H6N2)

1-Methylpyrazole(cas: 930-36-9) belongs to pyrazoles. Pyrazoles and their related multiring analogs are common elements of a wide variety of bioactive compounds. These ring structures are rare in nature. A consequence of this is that they have previously been thought to be poor moieties to include in potential new drugs. Synthetic Route of C4H6N2

Application of 930-36-9On November 1, 2021 ,《Design, synthesis and biological evaluation of naphthalene-derived (arylalkyl)azoles containing heterocyclic linkers as new anticonvulsants: A comprehensive in silico, in vitro, and in vivo study》 appeared in European Journal of Pharmaceutical Sciences. The author of the article were Valipour, Mehdi; Naderi, Nima; Heidarli, Elmira; Shaki, Fatemeh; Motafeghi, Farzaneh; Talebpour Amiri, Fereshteh; Emami, Saeed; Irannejad, Hamid. The article conveys some information:

In continuation of our research to find strong and safe anticonvulsant agents, a number of (arylalkyl)azoles (AAAs) containing naphthylthiazole and naphthyloxazole scaffolds were designed and synthesized. The in vivo anticonvulsant evaluations in BALB/c mice revealed that some of them had significant anticonvulsant activity in both maximal electroshock (MES) and pentylenetetrazole (PTZ) models of epilepsy. The best profile of activity was observed with compounds containing imidazole and triazole rings (C1, C6, G1, and G6). In particular, imidazolylmethyl-thiazole C1 with median ED (ED50)= 7.9 mg/kg in the MES test, ED50= 27.9 mg/kg in PTZ test, and without any sign of neurotoxicity (in the rotarod test, 100 mg/kg) was the most promising compound The patch-clamp recording was performed to study the mechanism of action of the representative compound C1 on hippocampal dentate gyrus (DG) cells. The results did not confirm any modulatory effect of C1 on the voltage-gated ion channels (VGICs) or GABAA agonism, but suggested a significant reduction of excitatory postsynaptic currents (EPSCs) frequency on hippocampal DG neurons. Sub-acute toxicity studies revealed that administration of the most active compounds (C1, C6, G1, and G6) at 100 mg/kg bw/day for two weeks did not result in any mortality or significant toxicity as evaluated by assessment of biochem. markers such as lipid peroxidation, intracellular glutathione, total antioxidant capacity, histopathol. changes, and mitochondrial functions. Other pharmacol. aspects of compounds including mechanistic and ADME properties were investigated computationally and/or exptl. Mol. docking on the NMDA and AMPA targets suggested that the introduction of the heterocyclic ring in the middle of AAAs significantly affects the affinity of the compounds The obtained results totally demonstrated that the prototype compound C1 can be considered as a new lead for the development of anticonvulsant agents. In addition to this study using 1-Methylpyrazole, there are many other studies that have used 1-Methylpyrazole(cas: 930-36-9Application of 930-36-9) was used in this study.

In 2016,European Journal of Organic Chemistry included an article by Belaroussi, Rabia; El Hakmaoui, Ahmed; Akssira, Mohamed; Guillaumet, Gerald; Routier, Sylvain. Electric Literature of C9H9N3O2. The article was titled 《Regioselective Synthesis of 2,4-Substituted Pyrido[1′,2′:1,5]pyrazolo[3,4-d]pyrimidines through Sequential Pd-Catalyzed Arylation and SNAr Reactions》. The information in the text is summarized as follows:

The synthesis and regioselective functionalization of rare 2,4-disubstituted-pyrido[1′,2′:1,5]pyrazolo[3,4-d]pyrimidine derivatives is reported. C-4 aminations were performed by chlorine nucleophilic substitution SNAr reactions, and their efficiencies were compared with those for direct one-pot amide C-O activation with bromotripyrrolidinophosphonium hexafluorophosphate (PyBroP) as a reagent. The latter method was used to perform palladium-catalyzed C-4 (het)arylation. Finally, two C-4 amino and aryl derivatives were prepared on a large scale and engaged in desulfurative Liebeskind-Srogl-type reactions under microwave irradiation to afford the envisioned compound library. Each step was optimized, and the results are discussed. In the experiment, the researchers used many compounds, for example, Methyl 2-aminopyrazolo[1,5-a]pyridine-3-carboxylate(cas: 1620075-73-1Electric Literature of C9H9N3O2)

Methyl 2-aminopyrazolo[1,5-a]pyridine-3-carboxylate(cas: 1620075-73-1) belongs to pyrazoles. Pyrazoles are commonly used scaffold molecules in drug discovery projects. The use of pyrazole derivatives is based on their analgesic, anti-inflammatory, antipyretic, antiarrhythmic, sedative, muscle relaxant, neuroleptic, anticonvulsant, monoamine oxidase inhibitory, antidiabetic and antibacterial activities.

Perez, Jorge D.; Yranzo, Gloria I.; Phagouape, Leonardo M. published an article on February 28 ,1986. The article was titled 《Influence of N-substitution in the FVT (flash vacuum thermolysis) of pyrazoles》, and you may find the article in Bulletin de la Societe Chimique de France.Safety of 1-Butyl-1H-pyrazole The information in the text is summarized as follows:

Flash vacuum thermolysis of 1-ethyl-, 3,5-dimethyl-1-ethyl- (I), 1-butyl-, 1-tert-butyl-, 3,5-dimethyl-1-phenyl- and 1-phenylpyrazole was studied. In the N-alkyl derivatives, pyrazole elimination and olefin formation were found. In contrast, Ph derivatives afforded isomerization and nitrogen extrusion. Kinetic parameters for compound I are described and a general mechanism including the N-H derivatives is discussed. In the part of experimental materials, we found many familiar compounds, such as 1-Butyl-1H-pyrazole(cas: 52096-24-9Safety of 1-Butyl-1H-pyrazole)

Pteridinones were designed based on a non-selective kinase template. Because of the uniqueness of the PI3K and mTOR binding pockets, a Me group was introduced to C-4 position of the peteridinone core to give compounds with excellent selectivity for PI3K and mTOR. This series of compounds were further optimized to improve their potency against PI3Kα and mTOR. Finally, orally active compounds with improved solubility and robust in vivo efficacy in tumor growth inhibition were identified as well. In the part of experimental materials, we found many familiar compounds, such as 3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole(cas: 844501-71-9Formula: C9H15BN2O2)
