Rani, Dixita published the artcileAsymmetric Michael Addition of Unactivated Ketones with β-Nitrostyrenes Mediated by Bifunctional L-Prolinamide Organocatalysts, Formula: C9H6N2O2, the publication is ChemistrySelect (2020), 5(8), 2435-2440, database is CAplus.

The catalytic activity of two types of L-prolinamide organocatalysts was investigated for asym. Michael addition reaction of cyclic/acyclic ketones with β-nitrostyrens. L-Prolinamides bearing amino groups as efficient catalyst as well as selectivity was found to be dependent upon the position of amine group to the amide bond. Organocatalyst having -NH₂ group ortho to amide bond provided the best results. Substrate scope was also studied by performing the reaction of various β-nitrostyrenes with ketones to afforded the corresponding Michael adducts in excellent yields with very high diastereoselectivities and enantioselectivities in almost all cases.

Morwick, Tina published the artcileEvolution of the Thienopyridine Class of Inhibitors of IκB Kinase-β: Part I: Hit-to-Lead Strategies, Application of 2-Aminomalononitrile 4-methylbenzenesulfonate, the publication is Journal of Medicinal Chemistry (2006), 49(10), 2898-2908, database is CAplus and MEDLINE.

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 benzopteridine I (R = NH2, R1 = R2 = H) was prepared by condensing 6-chloro-2-oximinocyclohexanone-HCl with H2NCH(CN)2.4-MeC6H4SO3H, aromatizing the quinoxaline oxide II by heating with HOAc, and condensing 2-amino-3-cyanoquinoxaline (III) with guanidine-HCl. Condensation of III with HC(OEt)3 gave I (R-R2 = H). I (R = NH2, R1 = R2 = H) was treated with HCl to give benzo[g]pterin. I [R = NH2, R1R2 = (CH)4] was obtained from 2-oximino-1-tetralone.

Eleven homologous 2,4-diaminocycloalka[g]pteridines and derivatives with cycloalkane ring size varying from 5 to 15 were prepared by cyclic condensation of aminomalonitrile tosylate [5098-14-6] with α-oximinocycloalkanones to give aminocyanocycloalka[b]pyrazine oxides followed by deoxygenation and guanidine cyclization, or guanidine cyclization of the pyrazine oxides followed by deoxygenation, or by condensation of 2,4,5,6-tetraaminopyrimidine-HCl [39944-62-2] with a cycloalka-1,2-dione. Inhibition of dihydrofolate reductase [9002-03-3] from Lactobacillus casei, rat liver, L1210, and Trypanosoma cruzi depended on cycloalkane ring size, with 2,4-diaminocyclododeca[g]pteridine (I) [53274-34-3] being most active.

Based on recent discoveries concerning the numerous biol. properties of thiazolidinones and thiosemicarbazones, new N-substituted heterocyclic derivatives I [R = F, H, 3-Cl, 3-CF₃, 2-C≡N], II and III had been designed by combining the indole ring with thioxothiazolidinone, thiazolidinone or thiosemicarbazone. Thus, a series of new thioxothiazolidinone, thiazolidinone, or thiosemicarbazone derivatives I, II and III bearing indole-based moiety have been designed, synthesized, and developed in good yields.

Mohr, Lisa-Marie published the artcileVisible light-mediated intermolecular [2 + 2] photocycloaddition of 1-aryl-2-nitroethenes and olefins, Name: (E)-4-(2-Nitrovinyl)benzonitrile, the publication is Organic & Biomolecular Chemistry (2019), 17(30), 7192-7203, database is CAplus and MEDLINE.

Despite the importance of cyclobutanes there are not many direct [2 + 2] photocycloaddition reactions which can be performed with visible light in the absence of a catalyst. A notable exception is the reaction of 1-aryl-2-nitroethenes and olefins which can be performed at a wavelength of λ = 419 nm or λ = 424 nm in CH₂Cl₂ as the solvent. In the present study, a total of 15 1-aryl-2-nitroethenes were found to undergo a [2 + 2] photocycloaddition with 2,3-dimethyl-2-butene (28-86% yield) and a set of 12 olefins was studied in their photocycloaddition to 1-phenyl-2-nitroethene (37-88% yield). All mechanistic results are in agreement with a triplet reaction pathway and with the intermediacy of a 1,4-diradical.

A directed screen of a relatively small number of compounds, selected for kinase ATP pocket binding potential, yielded a novel series of hit compounds (1). Hit explosion on two binding residues identified compounds 27 and 43 as the best leads for an optimization program having reduced secondary metabolism, as measured by in vitro rat hepatocytes incubation, leading to oral bio-availability. Structure-activity relationships and mol. modeling have suggested a binding mode for the most potent inhibitor 12.

Ten ¹⁴C-labeled metabolites were isolated from either bile (6 metabolites) or urine (7 metabolites) from chickens given single oral doses of 2,6-dichlorobenzo[¹⁴C]nitrile ([¹⁴C]dichlobenil). 2-(S-Glutathionyl)-3-hydroxy-6-chlorobenzo[¹⁴C]nitrile perfused through chicken kidneys in situ was excreted in urine from the perfused kidney (44% dose) as 2-mercapto-3-hydroxy-6-chlorobenzonitrile. Dichlobenil was fed at 0, 75, 150, or 225 ppm in the diet to broiler and laying strains of cockerels to determine biol. activity. Feed consumption and growth were not affected, but liver and kidney weights were higher in chicks fed the dichlobenil. The percentage of lipid or nitrogen in the livers and kidneys from chicks fed dichlobenil did not differ from controls and histol. or ultrastructural changes were not observed in these tissues.

Haight, Anthony R. published the artcileA Scaleable Synthesis of Fiduxosin, Name: 2-Aminomalononitrile 4-methylbenzenesulfonate, the publication is Organic Process Research & Development (2004), 8(6), 897-902, database is CAplus.

Fiduxosin (I) is under development for the treatment of benign prostatic hyperplasia. A convergent strategy required methodologies for preparation of an enantiomerically pure 3,4-cis-disubstituted pyrrolidine and a 2,3,5-trisubstituted thienopyrazine in a regiospecific manner. A [3+2] cycloaddition of an enantiopure azomethine ylide followed by a diastereoselective crystallization was employed to prepare the benzopyranopyrrolidine in high diastereomeric and enantiomeric purity. Conditions for reduction of an O-aryl lactone susceptible to epimerization were developed, and cyclization of the alc./phenol to the ether was accomplished in high yield. The thienopyrazine was prepared by condensation of Me thioglycolate and a regiospecifically prepared 2-bromo-3-cyano-5-phenylpyrazine. Conditions for effective halogen substitutive deamination to prepare regiospecific trisubstituted pyrazines is described.

Pagga, Udo published the artcileInhibition of nitrification in laboratory tests and model wastewater treatment plants, Computed Properties of 13312-84-0, the publication is Chemosphere (2006), 65(1), 1-8, database is CAplus and MEDLINE.

Nitrification in wastewater treatment plants is a sensitive microbiol. process, which can be disturbed by toxic substances. Two laboratory methods for nitrification inhibition (ISO standard 9509 and a modification of the respiration inhibition test ISO 8192) were studied with selected substances and compared with results from sewage model plants. For the prediction and prevention of interferences, the simple but reliable laboratory test methods proved to be very suitable. The tests in laboratory plants allowed a much more comprehensive evaluation of nitrification processes and showed their dependence on biodegradation and adaptation processes. The inhibition of nitrification depended on the mode of application and the biodegradability of the potential inhibitory compound and was much less severe with biodegradable substances than with poorly degradable ones.
