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

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

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.

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.
