Dibenzazepine-linked isoxazoles: New and potent class of α-glucosidase inhibitors

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.

One-pot Synthesis of Some Novel Xanthine Derived Isoxazoles as Potent Antibacterial Agents

In search of better antibacterial agents, a series of novel xanthine derived 3,5-disubstituted isoxazole derivatives were synthesized (3a-3j) in one-pot using 8-chloro-1,3-dimethyl-7-(prop-2-yn-1-yl)-1H-purine-2,6(3H,7H)-dione and aromatic aldehydes and f

One-pot synthesis of novel ether-linked diisoxazole derivatives via sequential O-propargylation and 1,3-dipolar cycloaddition from 2-bromohomoallylic alcohols

A simple and efficient, one-pot approach for the synthesis of ether-linked diisoxazole derivatives has been developed through sequential reactions, which includes O-propargylation of 2-bromohomoallylic alcohols with propargyl bromide in the presence of so

Design and synthesis of spiro derivatives of parthenin as novel anti-cancer agents

Several novel spiro derivatives of parthenin (1) have been synthesized by the dipolar cycloaddition using various dipoles viz; benzonitrile oxides, nitrones and azides with exocyclic double bond of C ring (α-methylene- γ-butyrolactone). Majority of the compounds exhibited improved anti-cancer activity compared to the parthenin, when screened for their in vitro cytotoxicity against three human cancer cell lines viz., SW-620, DU-145 and PC-3. In vivo screening of select analog revealed improved anti-cancer activity with low mammalian toxicity as compared to parthenin. The results of the cytotoxicity pattern of these derivatives reveals the SAR of these sesquiterpinoid lactones and possible role of α,β-unsaturated ketone of parthenin in inhibiting NF-kB. A mechanistic correlation of anti-cancer activity along with in vivo and western blotting experiments has been described.

Anionic domino C-O-heterocyclization approach for the synthesis of 5-vinyl isoxazolines

5-Vinyl isoxazolines were isolated in high yields through domino nucleophilic addition-anionic C-O-heterocyclization, when allyl organometallics derived from trans-1,4-dihalobutene were reacted with nitrile oxides. Georg Thieme Verlag Stuttgart.

Reaction of allenylmagnesium and allenylindium bromides with nitrile oxides: synthesis of novel 5-butynyl- and 5-methylisoxazoles

5-Butynylisoxazoles were obtained in high yields through a domino addition, C-O heterocyclization involving allenylmagnesium bromide and benzonitrile oxide in dry THF, in which the corresponding 5-methylisoxazoles were isolated in trace amounts. However, when the reactions were attempted in aqueous media using allenylindium bromide, 5-methylisoxazoles were formed as the sole products in high yields.
