WEB (water extract of banana): An efficient natural base for one-pot multi-component synthesis of 2-amino-3,5-dicarbonitrile-6-thio-pyridines

One-pot multi-component synthesis of 2-amino-3,5-dicarbonitrile-6-thio-pyridines derivatives using WEB (water extract of banana peels ash) as a green catalyst is described. A variety of aromatic aldehydes (with electron-donating and electron-withdrawing groups) in conjunction with aromatic and aliphatic thiols are known to tolerate this reaction condition using WEB. The reaction has simple work up procedure without using toxic solvents.

Synthesis, in vitro and in silico screening of 2-amino-4-aryl-6-(phenylthio) pyridine-3,5-dicarbonitriles as novel α-glucosidase inhibitors

Inhibition of α-glucosidase enzyme is of prime importance for the treatment of diabetes mellitus (DM). Apart of many organic scaffolds, pyridine based compounds have previously been reported for wide range of bioactivities. The current study reports a series of pyridine based synthetic analogues for their α-glucosidase inhibitory potential assessed by in vitro, kinetics and in silico studies. For this purpose, 2-amino-4-aryl-6-(phenylthio)pyridine-3,5-dicarbonitriles 1–28 were synthesized and subjected to in vitro screening. Several analogs, including 1–3, 7, 9, 11–14, and 16 showed many folds increased inhibitory potential in comparison to the standard acarbose (IC50 = 750 ± 10 μM). Interestingly, compound 7 (IC50 = 55.6 ± 0.3 μM) exhibited thirteen-folds greater inhibition strength than the standard acarbose. Kinetic studies on most potent molecule 7 revealed a competitive type inhibitory mechanism. In silico studies have been performed to examine the binding mode of ligand (compound 7) with the active site residues of α-glucosidase enzyme.

Heterogeneous Cu(II)/l-His@Fe3O4 nanocatalyst: A novel, efficient and magnetically-recoverable catalyst for organic transformations in green solvents

A novel, efficient and green Cu(ii)/l-His@Fe3O4 catalyst has been applied successfully in the synthesis of heterocyclic compounds. The resulting catalyst was used in the synthesis of 2,3-dihydroquinazolin-4(1H)-ones, polyhydroquinolines and 2-amino-6-(arylthio)pyridine-3,5-dicarbonitriles as biologically interesting compounds. The present research is focused on investigation of recycling, reusability and stability of the catalyst in phase reactions. The Cu(ii)/l-His@Fe3O4 catalyst was used at least six times with comparable activities to that of fresh catalyst. The chemical composition and the structure of the catalyst were analysed by TGA/DTG, EDS, XRD, VSM, FT-IR and SEM.

Structure-kinetics relationships of Capadenoson derivatives as adenosine A1 receptor agonists

Abstract We report the synthesis and biological evaluation of new derivatives of Capadenoson, a former drug candidate that was previously advanced to phase IIa clinical trials. 19 of the 20 ligands show an affinity below 100 nM at the human adenosine A1 receptor (hA1AR) and display a wide range of residence times at this target (from approx. 5 min (compound 10) up to 132 min (compound 5)). Structure-affinity and structure-kinetics relationships were established, and computational studies of a homology model of the hA1AR revealed crucial interactions for both the affinity and dissociation kinetics of this family of ligands. These results were also combined with global metrics (Ligand Efficiency, cLogP), showing the importance of binding kinetics as an additional way to better select a drug candidate amongst seemingly similar leads.
