α-Glucosidase inhibition is a valid approach for controlling hyperglycemia in diabetes. In the current study, new molecules as a hybrid of isoxazole and dibenzazepine scaffolds were designed, based on their literature as antidiabetic agents. For this, a series of dibenzazepine-linked isoxazoles (33–54) was prepared using Nitrile oxide-Alkyne cycloaddition (NOAC) reaction, and evaluated for their α-glucosidase inhibitory activities to explore new hits for treatment of diabetes. Most of the compounds showed potent inhibitory potency against α-glucosidase (EC 3.2.1.20) enzyme (IC50 = 35.62 ± 1.48 to 333.30 ± 1.67 μM) using acarbose as a reference drug (IC50 = 875.75 ± 2.08 μM). Structure-activity relationship, kinetics and molecular docking studies of active isoxazoles were also determined to study enzyme-inhibitor interactions. Compounds 33, 40, 41, 46, 48–50, and 54 showed binding interactions with critical amino acid residues of α-glucosidase enzyme, such as Lys156, Ser157, Asp242, and Gln353.

An efficient supported ionic liquid catalyst is designed for condensation reaction of aldehydes and ketones. The Zr-based metal–organic framework (MOF), UiO-66-NH2, was initially functionalized with N,N′-dibutyl imidazolium ionic liquid (UiO-66-NH2-ILBr–), and then urea was attached to the ionic liquid (IL) to form a task-specific IL. Bromide was exchanged with tetrafluoroborate and the catalyst exhibits excellent performance for the synthesis of oximes. The ionic liquid/urea coupling showed a synergistic effect on the efficiency of the reaction. The supported catalyst system was recycled simply by filtration and reused for five times without significant decrease in its activity. The catalyst was characterized with PXRD, FTIR, TGA, XPS, BET, FE-SEM, EDS, elemental mapping and elemental analysis (CHN). Graphic Abstract: MOF/IL/urea catalytic system was used for the synthesis of oximes[Figure not available: see fulltext.].
