Ferris, James P.; Orgel, L. E. published an article in 1965, the title of the article was Aminomalononitrile and 4-amino-5-cyanoimidazole in hydrogen cyanide polymerization and adenine synthesis.Reference of 2-Aminomalononitrile 4-methylbenzenesulfonate And the article contains the following content:

Aminomalononitrile (I) was prepared by the treatment of oximinomalononitrile with Al-Hg; p-toluenesulfonate derivative m. 180-1°. Treatment of I with acid anhydride gave the corresponding oxazoles (II). I is converted to III by reaction with formamidine acetate (IV). Further treatment of III with IV gave adenine. KCN and I react at pH 9-10 to give a brown polymer and diaminomaleonitrile (V). V is the most prominent low-mol.-weight product formed during the polymerization of HCN. The results indicate that I is a key intermediate in HCN polymerizations and possibly prebiol. organic synthesis. The experimental process involved the reaction of 2-Aminomalononitrile 4-methylbenzenesulfonate(cas: 5098-14-6).Reference of 2-Aminomalononitrile 4-methylbenzenesulfonate

2-Aminomalononitrile 4-methylbenzenesulfonate(cas:5098-14-6) belongs to nitriles. 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.Reference of 2-Aminomalononitrile 4-methylbenzenesulfonate

Ferris, James P. published an article in 1966, the title of the article was Studies in prebiotic synthesis. I. Aminomalononitrile and 4-amino-5-cyanoimidazole.COA of Formula: C10H11N3O3S And the article contains the following content:

The syntheses of aminomalononitrile and 4-amino-5-cyanoimidazole are described. Acid anhydrides react with aminomalononitrile to yield oxazoles. Aminomalononitrile is converted to diaminomaleonitrile by cyanide and to 4-amino-5-cyanoimidazole by formamidine. Adenine results from the reaction of 4-amino-5-cyanoimidazole with formamidine. 4-Cyano-5-aminooxazole is converted to 7-aminooxazolo[5,4-d]pyrimidine on treatment with formamidine. 16 references.

New synthesis and some biological studies.Safety of 2-Aminomalononitrile 4-methylbenzenesulfonate And the article contains the following content:

Conversion of methotrexate (I) [59-05-2] and 3′,5′-dichloromethotrexate (II) [528-74-5] to their 7-methyl analogs III [35190-25-1] and IV [53729-18-3], resp., to prevent metabolism in vivo to the inactive 7-hydroxy derivatives resulted in marked loss of antileukemic activity in mice and in vitro and loss of inhibitory potency against purified dihydrofolate reductase [9002-03-3] from Lactobacillus casei and L1210-FR8 tumor. The lack of antitumor activity presumably resulted from impaired enzyme binding.

Baraldi, Pier Giovanni; Pavani, Maria Giovanna; Nunez, Maria del Carmen; Brigidi, Patrizia; Vitali, Beatrice; Gambari, Roberto; Romagnoli, Romeo published an article in 2001, the title of the article was Antimicrobial and antitumor activity of N-heteroimmine-1,2,3-dithiazoles and their transformation in triazolo-, imidazo-, and pyrazolopyrimidines.Safety of 2-Aminomalononitrile 4-methylbenzenesulfonate And the article contains the following content:

The reaction of Appel’s salt with o-aminonitrile heterocyclics gave the corresponding 4-chloro-5-heteroimmine-1,2,3-dithiazoles which were evaluated for their antibacterial, antifungal and antitumor activity. Although all these N-heteroimines were devoid of significant antibacterial activity, they showed significant antifungal activity. Moreover, the same derivatives represent highly versatile intermediates in heterocyclic synthesis, in fact the pyrazoleiminodithiazoles can be converted in one step into 2-cyano derivatives of the corresponding 4-methoxy-pyrazolo[3,4-d]pyrimidines by sodium methoxide in refluxing methanol. This provides a general and attractive route to 4-methoxy-6-cyanopyrazolo[3,4-d]pyrimidines from 1-substituted 5-amino pyrazoles in two simple steps. Finally, the isosteric replacement of the pyrazole ring atoms to give the imidazole[3,4-d]pyrimidine and triazole [4,5-d]pyrimidine ring systems was examined The experimental process involved the reaction of 2-Aminomalononitrile 4-methylbenzenesulfonate(cas: 5098-14-6).Safety of 2-Aminomalononitrile 4-methylbenzenesulfonate

On July 3, 2003, Hirota, Kosaku; Kazaoka, Kazunori; Sajiki, Hironao published an article.Formula: C10H11N3O3S The title of the article was Synthesis and biological evaluation of 2,8-disubstituted 9-benzyladenines: discovery of 8-mercaptoadenines as potent interferon-inducers. And the article contained the following:

Recently, we have identified 9-benzyl-8-hydroxyadenines bearing an appropriate substituent (a butoxy, propylthio or butylamino group) at the 2-position as potent interferon (IFN)-inducers. Herein we report the design, synthesis, and IFN-inducing activity of 8-substituted 9-benzyladenines possessing such an appropriate substituent at the 2-position. Introduction of the appropriate substituent into the 2-position of the adenine nucleus gave rise to expression of the activity even in 9-benzyladenines bearing no hydroxyl group at the 8-position. An amino group at the 6-position and a hydroxyl or thiol group carrying an acidic proton at the 8-position are required to express excellent IFN-inducing activity. 9-Benzyl-2-butoxy-8-mercaptoadenine indicated the most potent activity with MEC of 0.001 μM. The experimental process involved the reaction of 2-Aminomalononitrile 4-methylbenzenesulfonate(cas: 5098-14-6).Formula: C10H11N3O3S

And the article contained the following:

High-throughput screening is routinely employed as a method for the identification of novel hit structures. Large numbers of active compounds are typically procured in this way and must undergo a rigorous validation process. This process is described in detail for a collection of screening hits identified as inhibitors of IκB kinase-β (IKKβ), a key regulatory enzyme in the nuclear factor-κB (NF-κB) pathway. From these studies, a promising hit series was selected. Subsequent lead generation activities included the development of a pharmacophore hypothesis and structure-activity relationship (SAR) for the hit series. This led to the exploration of related scaffolds offering addnl. opportunities, and the various structural classes were comparatively evaluated for enzyme inhibition, selectivity, and drug-like properties. A novel lead series of thienopyridines was thereby established, and this series advanced into lead optimization for further development. The experimental process involved the reaction of 2-Aminomalononitrile 4-methylbenzenesulfonate(cas: 5098-14-6).Computed Properties of 5098-14-6
