Functionalization of 1,2,3-Triazole to Pyrimidine, Pyridine, Pyrazole, and Isoxazole Fluorophores with Antimicrobial Activity

Abstract: The multi-component reaction of diacetyl triazole derivative with ethyl cyanoacetate and various aromatic aldehydes according to the conventional and solvent free methods leads to the corresponding 2-oxonicotinonitriles. A number of chalcones ha

Synthesis and bioactivity evaluation of eugenol hybrids obtained by Mannich and 1,3 dipolar cycloaddition reactions

Design, synthesis, and bioactivity evaluation of novel mannich bases (2a-2j) and triazole-chalcone derivatives (7a-7k) of Eugenol 1 were reported. Among all the derivatives tested for antiproliferative activity, di-amine manich derivative 2b (32.92 μM), a

Targeting the MKK7-JNK (Mitogen-Activated Protein Kinase Kinase 7-c-Jun N-Terminal Kinase) Pathway with Covalent Inhibitors

The protein kinase MKK7 is linked to neuronal development and the onset of cancer. The field, however, lacks high-quality functional probes that would allow for the dissection of its detailed functions. Against this background, we describe an effective co

Immobilization of vitamin B1 on the magnetic dialdehyde starch as an efficient carbene-type support for the copper complexation and its catalytic activity examination

Since the starch biopolymer is an available and inexpensive matrix with modifiable functionality and stabilization capability for metal ions, in this report, we oxidized it to dialdehyde form for the further functionalization with vitamin B1 as a green σ-donor and π-acceptor carbene type ligand. Immobilization of vitamin B1 on this biopolymer was done through imine bond formation between NH2 groups of aminopyrimidine segment of vitamin B1 and aldehyde functional groups of starch oxide. Thiazolium heterocycle part in this biomolecule provided a carbene type precursor for the metal complexation. After the magnetization process by using of Fe3O4 nanoparticles that lead to quick and facile magnetic separation and metal catalyst recycling, copper ions immobilized on the magnetic support (5.9 wt% Cu, 0.93 mmol/g). The prepared copper N-heterocyclic carbene complex (Fe3O4@DAS@VB1@CuCl nanocomposite) was characterized by FT-IR, SEM, EDX, XRD, VSM, TGA and ICP-OES analysis and then its catalytic activity investigated in azidonation of arylboronic acids and also one-pot coupling reaction of the synthesized aryl azides with phenylacetylene. 1,4-Diaryl 1,2,3-triazoles were obtained in excellent yields (≥90%) at proper reaction times (30–200 min). The magnetic catalyst was recovered by a magnetic field and reused in azidation reaction up to 7 cycle.

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.

Small Molecule Control of Morpholino Antisense Oligonucleotide Function through Staudinger Reduction

Conditionally activated, caged morpholino antisense agents (cMOs) are tools that enable the temporal and spatial investigation of gene expression, regulation, and function during embryonic development. Cyclic MOs are conformationally gated oligonucleotide analogs that do not block gene expression until they are linearized through the application of an external trigger, such as light or enzyme activity. Here, we describe the first examples of small molecule-responsive cMOs, which undergo rapid and efficient decaging via a Staudinger reduction. This is enabled by a highly flexible linker design that offers opportunities for the installation of chemically activated, self-immolative motifs. We synthesized cyclic cMOs against two distinct, developmentally relevant genes and demonstrated phosphine-triggered knockdown of gene expression in zebrafish embryos. This represents the first report of a small molecule-triggered antisense agent for gene knockdown, adding another bioorthogonal entry to the growing arsenal of gene knockdown tools.

Design, click conventional and microwave syntheses, DNA binding, docking and anticancer studies of benzotriazole-1,2,3-triazole molecular hybrids with different pharmacophores

Despite the availability of some drugs, there is an urgent need for effective anti-cancer medication. It is due to various side effects and non-functionality of the present drugs; especially at the late stage of cancer. Therefore, three series (4a-e, 6a-e and 8a-j; 21 compounds) of benzotriazole-1,2,3-triazole hybrids (carrying different pharmacophores) have been designed and synthesized (by both conventional and microwave syntheses) through the Cu(I)-catalyzed click 1,3-dipolar cycloaddition reaction of the propargylated benzotriazole with the appropriate aliphatic, aromatic and phenyl/benzyl acetamide azides. The syntheses times were from 6 to 12 h and 4 to 8 min in conventional and microwave syntheses. The yields were 80 to 86percent and 89 to 95percent in conventional and microwave syntheses; confirming microwave synthesis as an economic and eco-friendly method. These compounds were characterized by proper spectroscopic methods. The anticancer activities with A549 and H1299 lung cancer cell lines were in the range of 70.0 to 90.0percent for 4a-e series, 78.0 to 90.0percent for 6a-e series and 81.0 to 90.0percent for 8a-j series. The reported compounds showed good DNA binding constants in the range of 1.3 × 103 to 11.90 × 105 M?1. The docking results suggested strong DNA bindings of the reported compounds in the minor grooves of DNA; through hydrogen bonding and hydrophobic interactions. The quite good anticancer activities and high DNA binding constants have indicated that the reported molecules may be future anticancer agents.

SNAr azidation of phenolic functions utilizing diphenyl phosphorazidate

A useful method for the synthesis of aryl azides via SNAr reaction of phenol derivatives using diphenyl phosphorazidate (DPPA) as an azidation reagent was developed. Various phenol derivatives bearing electron-withdrawing groups were converted into the corresponding aryl azides in a single step. This method is easy to perform and enables the preparation of aryl azides without the use of explosive azide sources.

Preparation of aryl azides of aryl boronic acids and one-pot synthesis of 1,4-diaryl-1,2,3-triazoles by a magnetic cysteine functionalized GO–CuI/II nanocomposite

A mixed CuI/CuIIcatalyst based on magnetic cysteine functionalized graphene oxide (CuI/II@Cys-MGO) was prepared and used for the azidonation reaction of aryl boronic acids and one-pot synthesis of 1,4-diaryl ?1,2,3-triazoles. Aryl azides were obtained in good yields and short reaction times via cross-coupling of aryl boronic acids with sodium azide in the presence of CuII catalytic species in this catalytic system. The azide-alkyne cycloaddition reaction was catalyzed by CuI catalytic species in CuI/II@Cys-MGO nanocomposite.

New α-Hydroxy-1,2,3-triazoles and 9H-Fluorenes-1,2,3-triazoles: H Synthesis and Evaluation as Glycine Transporter 1 Inhibitors

Two series of new compounds containing 1,2,3-triazole moiety were designed as putative GlyT1 inhibitors aiming the discovery of new hits with activity in cognitive disorders. 1,4-Disubstituted α-hydroxy-1,2,3-triazoles were obtained as racemates in moderate to good yields by the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction (click chemistry) as the key step between propargyl alcohols and aryl azides, previously prepared from anilines or boronic acids. Benzo[c]chromene-triazoles were planned to be obtained by palladium-catalyzed C?H activation using [bis(trifluoroacetoxy)iodobenzene] (PhI(TFA)2) of some α-hydroxy-1,2,3-triazoles, since benzo[c]chromenes are also privileged groups with several biological activities, including to the central nervous system. Unexpectedly, 9H-fluorenes-1,2,3-triazoles, instead of benzo[c]chromenetriazoles, were obtained by Friedel-Crafts alkylation reaction. The two series of compounds were tested for inhibition of the glycine transporter (rat GlyT1 isoform) but only the α-hydroxy-1,2,3-triazole 9b was active (half maximal inhibitory concentration (IC50) = 8.0 μM).
