Combinatorial synthesis of new fluorescent scaffolds using click chemistry

Azides and acetylenes are bio-orthogonal functional groups that can be readily coupled using copper(I)- or ruthenium(II)- catalyzed 1,3-dipolar cycloaddition reactions. Using non-fluorescent aromatic azides and aromatic acetylenes, covering a range of electron rich and poor building blocks, the Huisgen cycloaddition afford 1,4-disubstituted or 1,5-disubstituted 1,2,3-triazoles. Using a combinatorial approach by running reaction in parallel in polypropylene 96-well plates we discovered several new fluorescent 1,2,3-triazoles scaffolds. These compounds show diverse interactions with biomolecules that could find applications in biology in, for example, fluorescence microscopy or biomolecule quantification.

Synthesis and antitumor activity of 1-substituted 1,2,3-triazole-mollugin derivatives

A new series of mollugin-1,2,3-triazole derivatives were synthesized using a copper(I)-catalyzed Huisgen 1,3-dipolar cycloaddition reaction of corresponding O-propargylated mollugin with aryl azides. All the compounds were evaluated for their cytotoxicity on five human cancer cell lines (HL-60, A549, SMMC-7721, SW480, and MCF-7) using MTS assays. Among the synthesized series, most of them showed cytotoxicity and most of all, compounds 14 and 17 exhibited significant cytotoxicity of all five cancer cell lines.

Primary discovery of 1-aryl-5-substituted-1H-1,2,3-triazole-4-carboxamides as promising antimicrobial agents

Three series of novel 1H-1,2,3-triazole-4-carboxamides: 1-aryl-5-alkyl/aryl-1H-1,2,3-triazole-4-carboxamides, 1-aryl-5-amino-1H-1,2,3-triazole-4-carboxamides and 1,2,3-triazolo[1,5-a]quinazoline-3-carboxamides were synthesized via base-mediated click azide reactions. Compounds were evaluated for their antimicrobial activities against primary pathogens: Gram-positive and Gram-negative bacterial strains Escherichia coli, Klebsiella pneumonia, Acinetobacter baumannii, Pseudomonas aeruginosa, Staphylococcus aureus, as well as fungal strain Cryptococcus neoformans var. grubii and Candida albicans. Compounds exhibiting moderate to good activities were selected for SAR analysis. Several 5-methyl-1H-1,2,3-triazole-4-carboxamides 4d, 4l, 4r, showed potent antibacterial effect against S. aureus. On the contrary, 5-amino-1H-1,2,3-triazole-4-carboxamide 8b and [1,2,3]triazolo[1,5-a]quinazoline-3-carboxamide 9a were active against pathogenic yeast C. albicans. Thus, compound 4l under 1 μM demonstrated 50% growth inhibition against S. aureus. At the same concentration, the compound 9a killed approx. 40% of C. albicans cells. In general, these compounds demonstrated selective action and no significant impact on the viability of human keratinocytes of HaCaT line.

Optimizing the aryl-triazole of cjoc42 for enhanced gankyrin binding and anti-cancer activity

Gankyrin is an oncoprotein overexpressed in numerous cancer types and appears to play a key role in regulating cell proliferation, cell growth, and cell migration. These roles are largely due to gankyrin's protein-protein interaction with the 26S proteaso

Synergistic combination of visible-light photo-catalytic electron and energy transfer facilitating multicomponent synthesis of β-functionalized α,α-diarylethylamines

A synthetic strategy with the visible-light photo-catalytic synergistic combination of electron and energy transfer processes has been developed. The mild reaction conditions allow the radical-radical cross-coupling phenomenon for the multicomponent synthesis of β-arylsulfonyl(diarylphosphinoyl)-α,α-diarylethyl-amines from readily available arylsulfinic acids (diarylphosphine oxides), 1,1-diarylethylenes and arylazides.

Controlled Transformations of Aryl Halides in a Flow System: Selective Synthesis of Aryl Azides and Aniline Derivatives

Copper-mediated nitrogenation of aryl halides with sodium azide can result in either aryl azides or aniline derivatives. The selectivity of the transformation is highly dependent on reaction time and temperature, which led to contradictory literature results with respect to product selectivity and the conditions applied. The advantages of a strictly controlled flow reactor environment were exploited in order to facilitate selective haloarene transformations. Reaction conditions were carefully investigated to understand their role on product selectivity. Aryl azides and aryl amines were successfully prepared from the same starting materials using the same auxiliaries by means of precise control over residence time and reaction temperature, thereby ensuring time-, cost- and atom-efficient syntheses. (Figure presented.).

Synthesis and evaluation of novel triazolyl quinoline derivatives as potential antileishmanial agents

The high potential of quinoline containing natural products and their derivatives in medicinal chemistry led us to discover novel series of 25 compounds for the development of new antileishmanial agents. A series of triazolyl 2-methyl-4-phenylquinoline-3-carboxylate derivatives has been synthesized via click chemistry inspired molecular hybridization approach and evaluated against Leishmania donovani. Most of the screened derivatives exhibited significant in vitro anti-leishmanial activity against promastigote (IC50 ranging from 2.43 to 45.75 μM) and intracellular amastigotes (IC50 ranging from 7.06 to 34.9 μM) than the control, miltefosine (IC50 = 8.4 μM), with less cytotoxicity in comparison to the standard drugs. Overall results revealed that prototype signify a new structural lead for antileishmanial chemotherapy.
