A Chemical Disruptor of the ClpX Chaperone Complex Attenuates the Virulence of Multidrug-Resistant Staphylococcus aureus

The Staphylococcus aureus ClpXP protease is an important regulator of cell homeostasis and virulence. We utilized a high-throughput screen against the ClpXP complex and identified a specific inhibitor of the ClpX chaperone that disrupts its oligomeric sta

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.

Rapid and selective synthesis of spiropyrazolines and pyrazolylphthalides employing Seyferth-Gilbert reagent

An unexpected product-selectivity in the reaction of 2-arylideneindane-1,3-dione with dimethyl diazomethylphosphonate leading to the formation of two different types of products is reported. The reaction carried out in acetone in the presence of catalytic amount of cesium fluoride afforded spiropyrazoline phosphonates via 1,3-dipolar cycloaddition reaction, whereas the reaction in methanol yielded an interesting class of pyrazolylphthalides. This strategy provides an efficient alternative method for the construction of pyrazolylphthalides, and moreover, the process is general, works under mild conditions, and exhibits high functional group compatibility.

Methylene amine substituted arylindenopyrimidines as potent adenosine A2A/A1 antagonists

A novel series of arylindenopyrimidines were identified as A2A and A1 receptor antagonists. The series was optimized for in vitro activity by substituting the 8- and 9-positions with methylene amine substituents. The compounds show excellent activity in mouse models of Parkinson's disease when dosed orally.
