- Indane-1,3-diones: As potential and selective α-glucosidase inhibitors, their synthesis, in vitro and in silico studies
-
Background: Diabetes mellitus is one of the most chronic metabolic disorders. Since past few years, our research group had synthesized and evaluated libraries of heterocyclic compounds against α and β-glucosidase enzymes and found encouraging results. The current study comprises of evaluation of indane-1,3-dione as antidiabetic agents based on our previously reported results obtained from closely related moiety isatin and its derivatives. Objective: A library of twenty three indane-1,3-dione derivatives (1-23) was synthesized and evaluated for α and β-glucosidase inhibitions. Moreover, in silico docking studies were carried out to in-vestigate the putative binding mode of selected compounds with the target enzyme. Methods: The indane-1,3-dione derivatives (1-23) were synthesized by Knoevenagel condensation of different substituted benzaldehydes with indane-1,3-dione under basic condition. The structures of synthetic molecules were deduced by using different spectroscopic techniques, including1 H-,13 C-NMR, EI-MS, and CHN analysis. Compounds (1-23) were evaluated for α and β-glucosidase inhibitions by adopting the literature protocols. Result: Off twenty three, eleven compounds displayed good to moderate activity against α-glucosidase enzyme, nonetheless, all compounds exhibited less than 50% inhibition against β-glucosidase enzyme. Compounds 1, 14, and 23 displayed good activity against α-glucosidase enzyme with IC50 values of 2.80 ± 0.11, 0.76 ± 0.01, and 2.17 ± 0.18 μM, respectively. The results have shown that these compounds have selectively inhibited the α-glucosidase enzyme. The in silico docking studies also supported the above results and showed different types of interactions of synthetic molecules with the active site of enzyme. Conclusion: The compounds 1, 14, and 23 have shown good inhibition against α-glucosidase and may potentially serve as lead for the development of new therapeutic representatives.

- Highly diastereoselective spiro-cyclopropanation of 2-arylidene-1,3-indanediones and dimethylsulfonium ylides
-
A highly diastereoselective spiro-cyclopropanation reaction of 2-arylidene-1,3-indanediones and dimethylsulfonium ylides has been developedviabase-induced annulation. This efficient and simple protocol features simple operations, mild conditions and excellent functional group compatibility. A variety of structurally interesting spiro-cyclopropanes were prepared in excellent yields and diastereomeric ratios (up to 97% yield and 20?:?1 dr). Also, ring expansion of the cyclopropanation product to quickly deliver a complex indeno[1,2-c]pyridazine structure showcased an interesting application of this method.

- Synthesis of novel indane-1,3-dione derivatives and their biological evaluation as anticoagulant agents
-
2-Substituted derivatives of indane-1,3-dione 3a-f , 5a-g, 6a-g were synthesized and investigated as anticoagulant agents. 2-Arylindane-1,3-diones (3) were obtained in the reaction of phthalide with appropriate arylaldehydes. 2-Arylmethyleneindane-1,3-diones (5) were prepared by condensation of indane-1,3-dione with the corresponding arylaldehydes. The compounds 5 were converted into their methyl analogues 6 by reduction with sodium tetrahydroborate. All of the compounds studied were screened for the anticoagulant activity. The highest prothrombin time was established for 2-[4-(methylsulfanyl) phenyl]indane-1,3-dione (3c) (PT = 33.71 (± 26.01) s), which was very close to PT of the drug anisindione (PT = 36.0 (± 26.42) s).
