Evaluation of 5H-Thiazolo[3,2-α]pyrimidin-5-ones as Potential GluN2A PET Tracers was written by He, Yingfang;Whitehead, David M.;Briard, Emmanuelle;Numao, Shin;Mu, Linjing;Schibli, Roger;Ametamey, Simon M.;Auberson, Yves P.. And the article was included in ChemMedChem in 2020.Quality Control of 4-(Ethylamino)benzonitrile This article mentions the following:

The authors describe their efforts to develop a PET tracer for imaging GluN2A-containing NMDA receptors, based on a 5H-thiazolo[3,2-α]pyrimidin-5-one scaffold. The metabolic stability and overall properties were optimized satisfactorily, although binding affinities remained a limiting factor for in vivo imaging. The authors identified [¹⁸F]pyrimidinone I as a radioligand providing good-quality images in autoradiog. studies, as well as [³H₂]pyrimidinylcyclopropanecarbonitrile II, which was used for the successful development of a radioligand binding assay. These are valuable new tools for the study of GluN2A-containing NMDA receptors, and for the optimization of allosteric modulators binding to the pharmacophore located at the dimer interface of the GluN1-GluN2A ligand-binding domain. In the experiment, the researchers used many compounds, for example, 4-(Ethylamino)benzonitrile (cas: 4714-63-0Quality Control of 4-(Ethylamino)benzonitrile).

4-(Ethylamino)benzonitrile (cas: 4714-63-0) belongs to nitriles. Nitriles are polar, as indicated by high dipole moments. As liquids, they have high relative permittivities, often in the 30s. Nitriles are susceptible to hydrogenation over diverse metal catalysts. The reaction can afford either the primary amine (RCH2NH2) or the tertiary amine ((RCH2)3N), depending on conditions.Quality Control of 4-(Ethylamino)benzonitrile

A bifunctionalized organic-inorganic hybrid silica: synergistic effect enhances enantioselectivity was written by Xiao, Wei;Jin, Ronghua;Cheng, Tanyu;Xia, Daquan;Yao, Hui;Gao, Fei;Deng, Boxin;Liu, Guohua. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2012.Category: nitriles-buliding-blocks This article mentions the following:

An imidazolium-based bifunctional heterogeneous catalyst exhibits excellent catalytic efficiency in asym. transfer hydrogenation of aromatic ketones in aqueous medium. The superior catalytic performance and the enhanced enantioselectivity is attributed to the synergistic effect of salient imidazolium phase-transfer function and the confined nature of the chiral organoiridium catalyst. In the experiment, the researchers used many compounds, for example, (R)-4-(1-Hydroxyethyl)benzonitrile (cas: 101219-69-6Category: nitriles-buliding-blocks).

(R)-4-(1-Hydroxyethyl)benzonitrile (cas: 101219-69-6) belongs to nitriles. The electronic structure of nitriles is very similar to that of an alkyne with the main difference being the presence of a set of lone pair electrons on the nitrogen. In conventional organic reductions, nitrile is reduced by treatment with lithium aluminium hydride to the amine. Reduction to the imine followed by hydrolysis to the aldehyde takes place in the Stephen aldehyde synthesis, which uses stannous chloride in acid.Category: nitriles-buliding-blocks

Large screening of DNA-compatible reaction conditions for Suzuki and Sonogashira cross-coupling reactions and for reverse amide bond formation was written by Favalli, Nicholas;Bassi, Gabriele;Bianchi, Davide;Scheuermann, Jorg;Neri, Dario. And the article was included in Bioorganic & Medicinal Chemistry in 2021.Related Products of 29809-13-0 This article mentions the following:

Progress in DNA-encoded chem. library synthesis and screening crucially relies on the availability of DNA-compatible reactions, which proceed with high yields and excellent purity for a large number of possible building blocks. In the past, exptl. conditions have been presented for the execution of Suzuki and Sonogashira cross-coupling reactions on-DNA. In this article, our aim was to optimize Suzuki and Sonogashira reactions, comparing our results to previously published procedures. We have tested the performance of improved conditions using 606 building blocks (including boronic acids, pinacol boranes and terminal alkynes), achieving >70% conversion for 84% of the tested mols. Moreover, we describe efficient exptl. conditions for the on-DNA synthesis of amide bonds, starting from DNA derivatives carrying a carboxylic acid moiety and 300 primary, secondary and aromatic amines, as amide bonds are frequently found in DNA-encoded chem. libraries thanks to their excellent DNA compatibility. In the experiment, the researchers used many compounds, for example, 5,6,7,8-Tetrahydronaphthalene-1-carbonitrile (cas: 29809-13-0Related Products of 29809-13-0).

5,6,7,8-Tetrahydronaphthalene-1-carbonitrile (cas: 29809-13-0) belongs to nitriles. There has been no report on the microbial biosynthesis of nitriles and the physiological function of such enzymes, nor was it not even known whether aliphatic and aromatic nitriles are biological compounds or just petrochemicals. Some nitriles are manufactured by heating carboxylic acids with ammonia in the presence of catalysts. This process is used to make nitriles from natural fats and oils, the products being used as softening agents in synthetic rubbers, plastics, and textiles and for making amines.Related Products of 29809-13-0

7-(Diethylamino)-2-oxo-2H-chromene-3-carbonitrile (cas: 51473-74-6) belongs to nitriles. Nitrile function is a very important functional group because it can be manipulated to other functional groups such as carboxylic acid by hydrolysis or amine by reduction, respectively. In addition, Nitriles can react with alkynes, which leads to an increase in carbon chain length (carbocyanation).Application of 51473-74-6

Design, synthesis and biological evaluation of new series of hexahydroquinoline and fused quinoline derivatives as potent inhibitors of wild-type EGFR and mutant EGFR (L858R and T790M) was written by Shaheen, Mennatallah A.;El-Emam, Ali A.;El-Gohary, Nadia S.. And the article was included in Bioorganic Chemistry in 2020.Product Details of 55490-87-4 This article mentions the following:

New series of hexahydroquinoline and fused quinoline derivatives were designed and synthesized. The thirty seven new compounds were screened for in vitro antitumor activity against HepG2, HCT-116 and MCF-7 cancer cells. Results indicated that certain compounds, including I, have the strongest potency against the three cancer cells, and they were further screened for in vitro cytotoxicity against A431 and H1975 cancer cells, as well as WI38 and WISH normal cells. Results revealed that I potently inhibited the growth of H1975 cells harboring EGFR^T790M mutation (IC₅₀ = 1.32 ± 0.2μM) over A431 cells overexpressing EGFR^WT (IC₅₀ = 4.96 ± 0.3μM). Moreover, the seven compounds displayed low cytotoxicity against the tested normal cells. The seven potent antitumor compounds were examined for their ability to inhibit the activity of EGFR^WT. The attained data manifested that I has remarkable EGFR^WT inhibitory activity (IC₅₀ = 0.083 ± 0.002μM) compared to erlotinib (IC₅₀ = 0.067 ± 0.002μM). Compound I was further studied for its enzymic inhibitory activity against other eight human kinases, and it displayed outstanding inhibitory activity against EGFR^L858R and EGFR^T790M mutants (IC₅₀ = 0.053 ± 0.002, 0.026 ± 0.001μM, resp.), as well as JAK3 (IC₅₀ = 0.069 ± 0.003μM). Anal. of cell cycle evidenced that I induces cell cycle arrest in G2/M and pre-G1 phases in the tested cancer cells. In addition, cancer cell death induced by I was proved to take place via apoptosis supported by elevated Bax/Bcl-2 ratio in the tested cancer cells. Moreover, docking results confirmed the good binding interactions of I with EGFR^WT, EGFR^L858R, EGFR^T790M and JAK3, which came in agreement with the results of in vitro enzyme assay. Further, I is predicted to have good oral absorption, good drug-likeness properties and low toxicity risks in human. In the experiment, the researchers used many compounds, for example, 2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4Product Details of 55490-87-4).

2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4) belongs to nitriles. The R-C-N bond angle in and nitrile is 180° which give a nitrile functional group a linear shape. Both the carbon and the nitrogen are sp hydridized which leaves them both with two p orbitals which overlap to form the two π bond in the triple bond.

Amination of benzylic C-H bonds by arylazides catalyzed by Co^II-porphyrin complexes: A synthetic and mechanistic study was written by Ragaini, Fabio;Penoni, Andrea;Gallo, Emma;Tollari, Stefano;Li Gotti, Claudia;Lapadula, Marta;Mangioni, Enrica;Cenini, Sergio. And the article was included in Chemistry – A European Journal in 2003.Computed Properties of C14H12N2 This article mentions the following:

Co^II-porphyrin complexes catalyze the reaction of aromatic azides (ArN₃) with hydrocarbons that contain a benzylic group (ArR¹R²CH) to give the corresponding amines (ArR¹R²C-N-HAr). When at least one of the R substituents is hydrogen, the catalytic reaction proceeds further to give the imine ArRC:NAr in good yields. The reaction mechanism has been investigated. The reaction proceeds through a reversible coordination of the arylazide to the Co^II-porphyrin complex. This unstable adduct can either react with the hydrocarbon in the rate-determining step or decompose by a unimol. mechanism to afford a putative “nitrene” complex, which reacts with more azide, but not with the hydrocarbon, to afford the byproduct diaryldiazene. The kinetics of the catalytic reaction have been investigated for a range of azides and substituted toluenes. Aryl azides with electron-withdrawing substituents react at a faster rate and a good correlation is found between the log(k) and the Taft parameters. On the other hand, an excellent correlation between the logarithm of the rate for substituted toluenes relative to that of toluene and a radical parameter (σ_JJ) alone was found, with no significant contribution by polar parameters. An explanation has been proposed for this anomalous effect and for the very high isotopic effect (k_H/k_D = 14) found. In the experiment, the researchers used many compounds, for example, 4-(Benzylamino)benzonitrile (cas: 10282-32-3Computed Properties of C14H12N2).

4-(Benzylamino)benzonitrile (cas: 10282-32-3) belongs to nitriles. Nitrile carbon shifts are in the range of 115�25 ppm whereas in isonitriles the shifts are around 155�65 ppm. Nitrile groups in organic compounds can undergo a variety of reactions depending on the reactants or conditions.

Affinity capacities and migration tendencies. V. The affinity capacity of the anisyl radical according to the dehydration of dialkylanisyl glycols and the isomerization of the corresponding ethylene oxides by heat was written by Tiffeneau, M.;Levy, Jeanne;Weill, Paul. And the article was included in Bulletin de la Societe Chimique de France in 1931.Recommanded Product: 5351-07-5 This article mentions the following:

It has been found, by the hydrolysis of oxazoles, studies of the halochromism of triarylcarbinols as well as by the cleavage of ketones under the influence of NaNH₂, that the affinity capacity or force attachment of the anisyl radical is 2-7 times greater than that of the Ph radical. Dehydration of the glycols PhCH(OH)C(OH)Me₂ and PhCH(OH)C(OH)(CH₂Ph)₂ and isomerization of the corresponding ethylene oxides have shown that the affinity capacities of the various radicals can be arranged in the order of decreasing magnitude, Me₂ > Ph > (PhCH₂)₂. The product obtained in the isomerization by heat of the oxide of MeOC₆H₄CH:CMe₂ (C. A. 20, 2850) has insufficiently characterized and was considered to be an aldehyde. This conclusion implied that the affinity capacity of anisyl was less than that of Me₂. A further study has shown that the product is a ketone, MeOC₆H₄CHMeAc formed according to the rearrangement, from which it is concluded that the affinity capacity of anisyl exceeds that of Me₂. Although it thus becomes futile to compare the affinity capacities of anisyl with those of other acyclic radicals, results of experiments made on the constitution of iodohydrins, the isomerization of ethylene oxides and the dehydration of glycols on the series AnCH:CR₂ (where An = anisyl and R = Me, Et, Pr and PhCH₂) are reported. The fixation of HOI on MeOC₆H₄CH:CMe₂ gives MeOC₆H₄CH(OH)CIMe₂, which with dry KOH yields anisyldimethylacetaldehyde I, MeOC₆H₄CMe₂CHO, b₁₈ 140-5°; oxime, m. 104-5°; anisyldimethylacetonitrile, b₂₀ 165-70°. I furnishes a rare example of a trisubstituted aldehyde which can form a bisulfite compound The product of the isomerization of anisyldimethylethylene oxide and of the dehydration of anisyldimethyl glycol is 2-anisyl-3-butanone, b. 260-5°; semicarbazone, 183-4°. The dehydration at 150° of 1-anisyl-2-ethyl-1-butanol, prepared from MeOC₆H₄MgBr and 3-ethyl-4-butanol, yields anisyldiethylethylene, MeOC₆H₄CH:CEt₂, b₁₄ 1340, n_D¹⁵ 1.532, d₀ 0.98, oxidized by BzO₂H to the ethylene oxide (II), b₁₆ 156-8°, n_D¹⁵ 1.515. Distillation of II in the presence of infusorial earth or pumice soaked in H₂SO₄ completely isomerizes it to 3-anisyl-4-hexanone (III), b₁₉ 158-60, n_D¹⁵ 1.523, d₀ 1.034 (semscarbazone, m. 138°), identical with the product prepared from the Na derivative of 1-anisyl-2-butanone with EtBr. The dehydration by heat or 50% H₂SO₄ of anisyldiethylglycol, MeOC₆H₄CH(OH)C(OH)Et₂, m. 78-9°, also produces III. Anisyldipropylethylene oxide, b₁₃ 162-5°, n_D¹⁵ 1.1512, d₀ 0.995, prepared by the action of Bz₂OH on anisyldipropylethylene, b₁₆ 162-5°, n_D¹⁵ 1.528, d₀ 0.953, is isomerized by distillation to 4-anisyl-5-octanone, b. 280°, n_D¹⁵ 1.511, d. 0.984 (semicarbazone, m. 97°), which is also formed by the dehydration by heat or 25% H₂SO₄ of anisyldipropylglycol, m. 93-4°, obtained in 50% yields by the action of 4 mols. of PrMgBr on 1 mol. of Et anisylglycolate. The distillation at reduced pressure of anisyldibenzylethylene oxide gives 2-anisyl-1,4-diphenyl-3-butanone (IV), stable to cold concentrated H₂SO₄ and to the action of alc. KOH at 150°, m. 75°; oxime, m. 95° (Ac derivative, m. 61-2°); isonitroso derivative, m. 153-4°. With PhCH₂MgCl, IV is transformed into anisyltribenzylethanol, m. 105-6°. The direct benzylation of acetylanisole, AcC₆H₄OMe, gives dibenzylacetylanisole, (PhCH₂)₂CHCOC₆H₄OMe, m. 93-5° (semicarbazone, m. 179-80°), not identical with IV. The latter is also formed by the dehydration of anisyldibenzyl glycol, prepared from PhCH₂MgBr and Et anisylglycolate. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenyl)-2-methylpropanenitrile (cas: 5351-07-5Recommanded Product: 5351-07-5).

2-(4-Methoxyphenyl)-2-methylpropanenitrile (cas: 5351-07-5) belongs to nitriles. Nitrile carbon shifts are in the range of 115�25 ppm whereas in isonitriles the shifts are around 155�65 ppm.
