On June 30, 2007, Abd El-Latif, Nehad A.; Amr, Abd El-Galil E.; Ibrahiem, Alhusain A. published an article.Formula: C12H7N3 The title of the article was Synthesis, reactions, and pharmacological screening of heterocyclic derivatives using nicotinic acid as a natural synthon. And the article contained the following:

A series of substituted pyridine derivatives were prepared from 3-acetylpyridine, which was prepared from the corresponding nicotinic acid as a natural starting material. Reaction of 3-acetylpyridine with indole-3-carboxaldehyde afforded the corresponding 3-β-(3-indolyl)(acryloyl)pyridine, which was treated with hydroxylamine hydrochloride in pyridine or acetic acid in the presence of sodium acetate to afford 3-β-(3-indolyl)(acryloyl)pyridine oxime and oxazole derivatives The oxime was treated with Et isothiocyanate or toluene-3,5-diisocyanate in refluxing dioxane to give the corresponding Et thiosemicarbazide and 3,5-bis(semicarbazide) derivative 3-β-(3-Indolyl)(acryloyl)pyridine was condensed with malononitrile in refluxing ethanol in the presence of piperidine as a catalyst to give a cyano(amino)pyran derivative, while it was condensed with Et cyanoacetate or malononitrile in the presence of ammonium acetate to yield (cyano)pyridone and cyano(amino)pyridine derivatives Cyclization of (acryloyl)pyridine with o-phenylenediamine in refluxing butanol led to the formation of the corresponding benzodiazepine via the intermediate A. Finally, cycloaddition reaction of (acryloyl)pyridine with thiourea yielded thioxopyrimidine, which was treated with chloroacetic acid to yield thiazolopyrimidine. An arylmethylene derivative was prepared by reacting thiazolopyrimidine with indole-3-carboxaldehyde or by treating thioxopyrimidine with indole-3-carboxaldehyde and chloroacetic acid in one step. The pharmacol. screening showed that many of the compounds thus prepared have good analgesic and anticonvulsant activities comparable to valdecoxib [i.e, 4-(5-methyl-3-phenyl-4-isoxazolyl)benzenesulfonamide] and carbamazepine as reference drugs. The experimental process involved the reaction of 2-((1H-Indol-3-yl)methylene)malononitrile(cas: 75629-62-8).Formula: C12H7N3

On February 25, 2018, Tuo, Wei; Bollier, Melanie; Leleu-Chavain, Natascha; Lemaire, Lucas; Barczyk, Amelie; Dezitter, Xavier; Klupsch, Frederique; Szczepanski, Fabien; Spencer, John; Chavatte, Philippe; Millet, Regis published an article.Electric Literature of 5098-14-6 The title of the article was Development of novel oxazolo[5,4-d]pyrimidines as competitive CB2 neutral antagonists based on scaffold hopping. And the article contained the following:

A series of novel oxazolo[5,4-d]pyrimidines I [R1 = H, Cl, F, CF3; R2 = H, Me; R3 = n-Bu, cyclohexylmethyl, 1-methylpiperazinyl, etc.] was designed via a scaffold hopping strategy and synthesized through a newly developed approach. All these compounds I were evaluated for their biol. activity toward CB1/CB2 cannabinoid receptors, their metabolic stability in mice liver microsomes and their cytotoxicity against several cell lines. Eight compounds I [R1 = Cl, CF3; R2 = H, Me; R3 = 1-methylpiperazinyl, 1-ethylpiperazinyl, 1-acetylpiperazinyl] were identified as CB2 ligands with Ki values less than 1 ΜM. It was noteworthy that compounds I [R1 = Cl; R2 = Me; R3 = 1-methylpiperazinyl, 1-ethylpiperazinyl] showed CB2 binding affinity in the nanomolar range and significant selectivity over CB1 receptors. Interestingly, functionality studies imply that they behaved as competitive neutral antagonists. Moreover, all tested compounds I were devoid of cytotoxicity toward several cell lines, including Chinese hamster ovary cells (CHO) and human colorectal adenocarcinoma cells HT29. The experimental process involved the reaction of 2-Aminomalononitrile 4-methylbenzenesulfonate(cas: 5098-14-6).Electric Literature of 5098-14-6

Lega, D. A.; Chernykh, V. P.; Shemchuk, L. A. published an article in 2016, the title of the article was The study of the three-component interaction between 1-ethyl-1H-2,1-benzothiazin-4(3H)-one 2,2 dioxide, hetarylcarbaldehydes and active methylene nitriles.HPLC of Formula: 75629-62-8 And the article contains the following content:

Some peculiarities of the three-component reaction of 1-ethyl-1H-2,1-benzothiazin-4(3H)-one 2,2-dioxide with active methylene nitriles and hetarylcarbaldehydes have been described in this article. It has been found that if malononitrile is used, the products of the three-component reaction are 2-amino-4-hetaryl-3-cyano-6-ethyl-4,6- dihydropyrano[3,2-c][2,1]benzothiazine 5,5-dioxides irresp. of the hetaryl fragment nature in the initial aldehyde. When using Et cyanoacetate as an active methylene nitrile instead of malononitrile the reaction lost its selectivity. In this case, depending on the hetarylcabaldehyde, three different types of products were obtained, namely, 2-amino-3-alkoxycarbonyl-4-hetaryl-4H-pyrans (for pyridine-3-, pyridine-4-carbaldehydes, and furan-2-carbaldehyde), triethylammonium salt of bis(1-ethyl-1H-2,1-benzothiazin-2,2- dioxo-4-ol-3-yl)(2-thienyl)methane (for thiophen-2-carbaldehyde) or Et 2-cyano-3-(1H-indol-3-yl)acrylate (for indole-3-carbaldehyde). Formation of a stable triethylammonium salts was considered as the process competitive with formation of 2-amino-4H-pyrans. This has allowed us to propose the modified mechanism of 2-amino-4H-pyran formation. This mechanism includes formation of triethylammonium salts of bis-adducts. According to this mechanism 2-amino-3-ethoxycarbonyl-4-(2-thienyl)-4H-pyran without any impurity of bis-adduct could be selectively obtained using the three-component reaction. Triethylammonium salts of bis-adducts were obtained by direct reaction of 1-ethyl-1H-2,1-benzothiazin-4(3H)-one 2,2-dioxide with hetarylcarbaldehydes in the presence of equimolar amounts of triethylamine. It has been shown that the three-component reaction of 1-ethyl-1H-2,1-benzothiazM(3H)-one 2,2-dioxide with active methylene nitriles and hetarylcarbaldehydes is a more effective tool for obtaining fused 2-amino-4-hetaryl-4H-pyrans compared to the stepwise approach. The experimental process involved the reaction of 2-((1H-Indol-3-yl)methylene)malononitrile(cas: 75629-62-8).HPLC of Formula: 75629-62-8
