Photosensitizing assemblies of pyrazine derivative PDA have been developed which exhibit a high photostability, ‘lighted’ excited state, balanced redox potential, high transportation potential and activate oxygen via type-I pathway only. These PDA assemblies in combination with Cu(II) ions catalyze the CuAAC reaction via in situ reduction of Cu(II) ions without any reducing or stabilizing agent. The present protocol has wide substrate scope with recyclability of the catalytic system up to six catalytic cycles and is applicable to gram-scale synthesis.

Saha, Ishita published the artcilePhenazinium dyes methylene violet 3RAX and indoine blue bind to DNA by intercalation: Evidence from structural and thermodynamic studies, Computed Properties of 4569-86-2, the publication is Dyes and Pigments (2013), 96(1), 81-91, database is CAplus.

The structural and energetic aspects of the interaction of two important phenazinium dyes methylene violet 3RAX and indoine blue with DNA were studied by spectroscopic and thermochem. techniques. The binding affinity values of both the dyes were of the order of 10⁵ M^-1 but methylene violet 3RAX bound to DNA more strongly. Both dyes bound DNA by intercalation but methylene violet 3RAX bound stronger than indoine blue. The DNA binding of both the dyes was exothermic and favored by a small neg. enthalpy and pos. entropy contributions. The effect of ionic strength indicated that electrostatic attraction is an important component of the dye-DNA interaction although the major contribution comes from hydrophobic forces. The temperature dependence of enthalpy changes yielded neg. heat capacity value which was higher for methylene violet 3RAX compared to indoine blue suggesting higher contribution from hydrophobic forces in the interaction of the former. Enthalpy-entropy compensation phenomenon was observed for the binding of both dyes to DNA.

Srikrishna, Devulapally published the artcilePEG-600 mediated one-pot reaction of 3-acetyl-2H-chromen-2-one with heterylthiols and phenylthioureas using tetrabutylammonium tribromide as an efficient green reagent, Application of 1-(4-Chlorophenyl)thiourea, the publication is New Journal of Chemistry (2017), 41(12), 5168-5175, database is CAplus.

A simple method for the one-pot reaction of 3-acetyl-2H-chromen-2-one with different heterylthiols and phenylthioureas under green conditions using tetrabutylammonium tribromide (TBATB) as an efficient reagent has been described. 3-Acetyl-2H-chromen-2-one was reacted with TBATB in acetic acid to give 3-(2-bromoacetyl)-2H-chromen-2-one. Poly(ethylene glycol) 600 (PEG-600) was found to be the effective solvent for this reaction. Thus, a one-pot reaction of equimolar amounts of 3-acetyl-2H-chromen-2-one, TBATB and heterylthiols or phenylthioureas, resulted in the formation of heterylthioacetylcoumarins I (X = NH, O, S) or coumarinylthiazoles II (Ar = C₆H₅, 4-FC₆H₄, 2-Cl-4-FC₆H₃, etc.), resp. The effect of the solvent on these reactions was studied. The merits of this preparation are the mild reaction conditions, easy workup, good yields and use of PEG-600 as a green reaction medium.

Suzuki, Keiko published the artcileA novel macroreticular-type fluorous polystyrene resin and its application to the synthesis of a 3-amino-β-carboline derivative with N-methyl-N-nitrosourea conjugation via fluorous solid-phase reaction: a comparative study of fluorous solid-, solid-, and liquid-phase reactions, SDS of cas: 42074-68-0, the publication is Tetrahedron (2015), 71(30), 4999-5012, database is CAplus.

A novel fluorous polystyrene (FPS) MR-resin was applied to a fluorous solid-phase (FSP) reaction. The MR-FPS resin actually was developed previously and possessed excellent chem. resistance to acids and alkalis, and a fluorous-tagged compound was homogeneously and loosely immobilized on the resin. The synthesis of an antitumor drug, an N-methyl-N-nirosourea conjugated 3-amino-β-carboline derivative, was accomplished with a high yield by using this new fluorous reaction system. Using only filtration, the fluorous 3-amino-β-carboline derivatives immobilized on the MR-FPS resin were easily recovered from the reaction mixtures As an extention of this approach, a diversity synthesis of 3-amino-9-benzyl-β-carboline derivatives was applied to the FSP method giving high yields. Finally, the FSP synthesis was compared with the corresponding conventional solid- and liquid-phase methods of synthesis. The FSP reaction was superior in terms of the reactivity of the substrate and the ease of product separation

Klovak, Viktoriia published the artcileFluorescent detection of decamethoxine by reaction with eosin Y in medicines, Category: chlorides-buliding-blocks, the publication is Journal of Chemical Sciences (Berlin, Germany) (2021), 133(4), 117, database is CAplus.

The influence of cationic, anionic, and nonionic surfactant solutions on the nature of the fluorescence spectra of reagents of different charges and hydrophobicity in aqueous solutions has been studied. The increase in the surfactant anal. signal with increasing contribution of the role of electrostatic interactions between the reagent particle and ionic surfactant has been shown. The observed effect is explained by the implementation of charge matching in the interaction of surfactants with the reagents. Hydrophobic binding of oppositely charged reagent particles and surfactants further enhances the effect of charge matching. The elimination of the detected effect for reagents that exhibit weak solvatochromic properties has been shown. The conditions for detecting the content of hydrophobic organic substances of cationic nature by reaction with eosin Y have been proposed.

The induction constants σ* of R groups correlated linearly with the chem. shift of 31P in 37 RP(O)(OEt)2 (R = alkyl or substituted alkyl groups), provided that hyperconjugation effects were taken into account. The presence of unshared electron pairs in R at the C atom adjacent to the P destroyed the linear relationship; the same was true of R groups containing multiple bonds.

The polymerization of terthiophene to obtain an alkene bridged α,α-coupled sexithiophene polymer, was controlled by light; i.e., the electropolymerizability of the bis-terthiophene monomer is switched off and on upon illumination with UV and visible light, resp. The system comprises both bis-terthiophene and photochromic dithienylethene units. The presence of a light-switchable unit allows on-off switching of the electropolymerization of the monomer with light. The incorporation of dithienylethene in the backbone increases dramatically the homogeneity of the polymer formed (i.e., only sexithiophene units are formed). The films are robust and fully retain electrochromism as was demonstrated through cyclic voltammetry while spatial control (patterning) is readily achieved by applying simple optical masking techniques.

Dreas, Agnieszka published the artcileDiscovery of indazole-pyridinone derivatives as a novel class of potent and selective MNK1/2 kinase inhibitors that protecting against endotoxin-induced septic shock, Quality Control of 939-99-1, the publication is European Journal of Medicinal Chemistry (2021), 113057, database is CAplus and MEDLINE.

The mitogen-activated protein kinase (MAPK)-interacting kinases 1 and 2 (MNKs 1/2) and their downstream target eIF4E, play a role in oncogenic transformation, progression and metastasis. These results provided rationale for development of first MNKs inhibitors, currently in clin. trials for cancer treatment. Inhibitors of the MNKs/eIF4E pathway are also proposed as treatment strategy for inflammatory conditions. Here we present results of optimization of indazole-pyridinone derived MNK1/2 inhibitors among which compounds I and II, selective and metabolically stable derivatives Both compounds decreased levels of eIF4E Ser206 phosphorylation (pSer209-eIF4E) in MOLM16 cell line. When administered in mice compounds I and II significantly improved survival rates of animals in the endotoxin LD challenge model, with concomitant reduction of proinflammatory cytokine levels – TNFα and IL-6 in serum. Identified MNK1/2 inhibitors represent a novel class of immunomodulatory compounds with a potential for the treatment of inflammatory diseases including sepsis.
