Fourteen N-[{(substituted-phenylthiazol-2-yl)-3-aryl-1H-pyrazol-4-yl}methylene]-5-substituted-thiazol-2-amine (5a-n) analogs were synthesized by the reaction of 3-aryl-1-(thiazol-2-yl)-1H-pyrazole-4-carbaldehyde and substituted thiazole amines. The structures of prepared compounds were delineated by elemental analysis, FT-IR and H-1 NMR spectra. These analogs were scrutinized for in vitro antiinfective and cytotoxic activities. Some thaizole clubbed pyrazole derivatives were assessed for their cytological changes in germ cells of Capra hircus by using histomorphological analysis, fluorescence assay and apoptosis quantification. Compound 51 having 4-NO2 substituent induced the significant apoptosis in tested cells of Capra hircus. The results revealed that compounds 5c, 5e, 5k, and 51 have commendable antibacterial activity within MIC range of 62.5-250 mu g/ml. Compound 5c emerged as a potent antimalarial compound by exhibiting IC50 value of 0.23 mu g/ml and compound 5j induced paralysis of Pherentima posthuma at 8.6 +/- 1.94 min and death at 20 +/- 5.04 min, respectively. Compound 5j revealed an excellent cytotoxicity at IC50 value of 30.7 and < 10 mu g/ml against MCF-7 and HeLa cells, respectively. Individually, compounds 5c, 5j and 51 could be considered as promising anti-infective and cytotoxic compounds. (C) 2020 Elsevier Ltd. All rights reserved.

We report an efficient catalytic protocol that chemo-selectively reduces nitroarenes to arylamines, by using methylhydrazine as a reducing agent in combination with the easily synthesized and robust catalyst tris(N-heterocyclic thioamidate) Co(III) complex [Co(kappa S,N-tfmp2S)(3)], tfmp2S = 4-(trifluoromethyl)-pyrimidine-2-thiolate. A series of arylamines and heterocyclic amines were formed in excellent yields and chemoselectivity. High conversion yields of nitroarenes into the corresponding amines were observed by using polar protic solvents, such as MeOH and ‘PrOH. Among several hydrogen donors that were examined, methylhydrazine demonstrated the best performance. Preliminary mechanistic investigations, supported by UV-vis and NMR spectroscopy, cyclic voltammetry, and high-resolution mass spectrometry, suggest a cooperative action of methylhydrazine and [Co(kappa S,N-tfmp2S)(3)] via a coordination activation pathway that leads to the formation of a reduced cobalt species, responsible for the catalytic transformation. In general, the corresponding N-arylhydroxylamines were identified as the sole intermediates. Nevertheless, the corresponding nitrosoarenes can also be formed as intermediates, which, however, are rapidly transformed into the desired arylamines in the presence of methylhydrazine through a noncatalytic path. On the basis of the observed high chemoselectivity and yields, and the fast and clean reaction processes, the present catalytic system [Co(kappa S,N-tfmp2S)(3)]/MeNHNH2 shows promise for the efficient synthesis of aromatic amines that could find various industrial applications.

Chiral ionic liquids (CILs) have shown a wide range of applications in variety of domains in chemistry. Because of this, synthesis and applications of CILs have always been areas of interest for research in the last 20 years. Present work describes, the synthesis of six carbohydrate based chiral ionic liquids (CCILs) by following simple procedures and their applications. Structures of the cats were confirmed through various analytical techniques like NMR spectroscopy (H-1, C-13, B-11, P-31,F-19), El-MS, and polarimetry. Designed CCILs were tested as chiral recognising agents using sodium salt of Mosher’s acid as model substrate through (FNMR)-F-19-N- spectroscopy. Further, Cats were used as organocatalyst in the enantioselective reduction of aromatic prochiral ketones to achieve corresponding chiral secondary alcohols. (C) 2019 Elsevier B.V.

A bifunctional 3d-metal catalyst for the cascade synthesis of diverse pyrroles from nitroarenes is presented. The optimal catalytic system Co/NGr-C@SiO2-L is obtained by pyrolysis of a cobalt-impregnated composite followed by subsequent selective leaching. In the presence of this material, (transfer) hydrogenation of easily available nitroarenes and subsequent Paal-Knorr/Clauson-Kass condensation provides >40 pyrroles in good to high yields using dihydrogen, formic acid, or a CO/H2O mixture (WGSR conditions) as reductant. In addition to the favorable step economy, this straightforward domino process does not require any solvents or external co-catalysts. The general synthetic utility of this methodology was demonstrated on a variety of functionalized substrates including the preparation of biologically active and pharmaceutically relevant compounds, for example, (+)-Isamoltane.

Deuterium- and tritium-labeled compounds play a principal role in tracing of biologically active molecules in complicated biochemical systems. The state-of-the-art techniques using noble metal catalysts or strong reducing agents often suffers from low functional group tolerances, poor selectivity, tricky or multistep synthesis of reagents, and low specific activity of the labeled product. Herein, we demonstrate a mild and nonmetallic technique of deuteration and tritiation of polarized double bonds, such as carbonyl compounds, yielding labeled alcohols of high specific activities. This one-pot synthesis uses carrier-free hydrogen gas in situ activated by a freshly prepared frustrated Lewis pair, generating reducing reagents. This labeling strategy shows better selectivity and functional group tolerances compared with current reductive methods. Reported is an example of the selective reduction of the aldehyde moiety of 3-acetylbenzaldehyde. What makes this technology groundbreaking is its mildness, selectivity, and generation of limited amount of radioactive waste as almost no byproducts were generated after use of (B(C6F5)(3)H-3)((HTMP)-H-3) reducing reagent. Radiochemical purity of desired H-3-labeled product in a crude reaction mixture was determined of over 94%. This work provides, to the community of radiochemists, a practical protocol for frustrated Lewis pairs (FLP)-assisted deuterium/tritium labeling technology.

Aberrant overexpression of heterogeneous nuclear ribonucleoprotein K (hnRNP K) is a key feature in oncogenesis and progression of many human cancers. hnRNP K has been found to be a transcriptional activator to up-regulate c-myc gene transcription, a critical proto-oncogene for regulation of cell growth and differentiation. Therefore, down-regulation of c-myc transcription by inhibiting hnRNP K through disrupting its binding to c-myc gene promoter is a potential approach for cancer therapy. In the present study, we synthesized and screened a series of Quinoline derivatives and evaluated their binding affinity for hnRNP K. Among these derivatives, (E)-1-(4-methoxyphenyl)-3-(4 morpholino-6-nitroquinolin-2-yl)prop-2-en-1-one (compound 25) was determined to be the first-reported hnRNP K binding ligand with its K-D values of 4.6 and 2.6 mu M measured with SPR and MST, respectively. Subsequent evaluation showed that the binding of compound 25 to hnRNP K could disrupt its unfolding of c-myc promoter i-motif, resulting in down-regulation of c-myc transcription. Compound 25 showed a selective anti-proliferative effect on human cancer cell lines with IC50, values ranged from 1.36 to 3.59 mu M. Compound 25 exhibited good tumor growth inhibition in a Hela xenograft tumor model, which might be related to its binding with hnRNP K. These findings illustrated that inhibition of DNA-binding protein hnRNP K by compound 25 could be a new and selective strategy of regulating oncogene transcription instead of targeting promoter DNA secondary structures such as G-quadruplexes or i-motifs.

An efficient and facile approach has been described for the synthesis of a new series of 1-amino-2-oxo-nicotinonitriles and their sulfonamides under microwave and ultrasonic irradiation. The desired compounds 4 a-l were obtained via condensation of p-chlorobenzaldehyde, aryl or heteroaryl methyl ketone and cyanoacetohydrazide in the presence of catalytic piperidine under three synthetic methodologies (namely, conventional method, ultrasonic and microwave irradiation), the best results (short reaction times, pure products, high yield) were obtained by ultrasonic irradiation. Sulfonamides 5 a-f resulted via reaction of amines 4 a-e and 4 j with benzene sulfonyl chloride in the presence of pyridine. The synthesized compounds give no significant results when investigated against Gm (+ve) and Gm (-ve) bacteria, and fungi strains.

Hydrofunctionalization, the direct addition of an X-H (e.g., X=O, N) bond across an alkene, is a desirable strategy to make heterocycles that are important structural components of naturally occurring molecules. Described here is the design and discovery of donor-acceptor-type platinum catalysts that are highly effective in both hydroalkoxylation and hydroamination of unactivated alkenes over a broad range of substrates under mild conditions. A number of alkene substitution patterns are accommodated, including tri-substituted, 1,1-disubstituted, (E)-disubstituted, (Z)-disubstituted and even mono-substituted double bonds. Detailed mechanistic investigations suggest a plausible pathway that includes an unexpected dissociation/re-association of the electron-deficient ligand to form an alkene-bound donor-acceptor-type intermediate. These mechanistic studies help understand the origins of the high reactivity exhibited by the catalytic system, and provide a foundation for the rational design of chiral catalysts towards asymmetric hydrofunctionalization reactions. The direct addition of an O-H (hydroalkoxylation) or an N-H (hydroamination) bond across an alkene is a useful strategy to access biologically relevant heterocycles. Here, the authors report donor-acceptor-type platinum catalysts that are effective for both hydroalkoxylation and hydroamination of unactivated alkenes, with broad substrate scope and use of mild conditions.

Simple alpha-(bromomethyl)styrenes can be processed to a variety of 1,1-difluorinated electrophilic building blocks via I(I)/I(III) catalysis. This inexpensive main group catalysis strategy employs p-TolI as an effective organocatalyst when combined with Selectfluor (R) and simple amine center dot HF complexes. Modulating Bronsted acidity enables simultaneous geminal and vicinal difluorination to occur, thereby providing a platform to generate multiply fluorinated scaffolds for further downstream derivatization. The method facilitates access to a tetrafluorinated API candidate for the treatment of amyotrophic lateral sclerosis. Preliminary validation of an enantioselective process is disclosed to access alpha-phenyl-beta-difluoro-gamma-bromo/chloro esters.
