the best lead for trifunctional inhibition against MAO A (0.34 μM), MAOB (0.26 μM), and AChE (52 μM), while 32 exhibited a lead for selective MAO A (0.12 μM) inhibition coupled to AChE (48 μM) inhibition. Computational analysis revealed that the malononitrile group can find an advantageous position with the aromatic cleft and FAD of MAO A or MAOB. However, the total binding energy can be handicapped

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

Copper‐exchanged tungstophosphoricacid (Cu‐TPA) is found to catalyze efficiently the coupling of propargyl alcohol (prop‐2‐yn‐1‐ol) with (arylmethylidene)malononitriles to afford the corresponding 2,3,4,5‐tetrahydro‐4‐methylidenefuran derivatives in good yields and with high selectivity. The catalyst is recycled and reused for three‐to‐four subsequent runs with a minimal decrease of activity.
