Antibacterial And Antioxidant Activity

Objective: Various benzilic acids and its analogs have been synthesized using the protocol, obtain good to exceptional yield and their biological activity, and its docking studies have been discussed.Methods: Molecular docking studies were performed by discovery studio - LibDock docking program. To determine the cytotoxic effects, we used an MTT viability assay.Results: The results showed that cell growth is significantly lower in extract treated cells compared to untreated control. The effect of inhibition of cell growth was shown in different concentration dosages for cytotoxic, antibacterial, and antioxidant activity in vitro.Conclusion: From the antibacterial results prove that the synthesized compounds showed the potential activity. These remarks may give the encouragement of further development of our research in this field. The antioxidant activity was also performed for the compound benzilic acid and its substituted analogs.

The purpose of this study was to investigate the antidiabetic effect of phytocompounds from Swietenia macrophylla seed using preliminary phytochemical screening, invitro antioxidant activity and molecular docking studies. The powdered seed extract of Swietenia macrophylla was to investigate the phytochemical screening exhibited the presence of alkaloid, phenols, tannins, flavonoids, terpenoids, steroids, carbohydrates, amino acids and proteins as major active constituents. The antioxidant activity of Swietenia macrophylla seed was evaluated by DPPH free radical scavenging assay. Rutin was used as a reference compound. The Swietenia macrophylla seed exhibited 56.0471% of free radical scavenging activity as compared with rutin. The molecular docking studies performed by using molecular docking server online respectively in which the antidiabetic target namely glutamine:fructose-6-phosphate amidotransferase (GFAT) (PDB id: 2ZJ3) have a potential interaction with swietenine, swietenolide, β-sitosterol, and fucosterol. In this study, the protein glutamine:fructose-6-phosphate amidotransferase (GFAT) was used from its structure perspectives. Its primary and secondary structures were evaluated using online tools. Its role in antidiabetic was assessed by molecular docking the compounds present in the seed extract of Swietenia macrophylla assayed by GC-MS analysis. This in-silico study demonstrates the interactions of active components of Swietenia macrophylla against Type I and Type II diabetes.

Novel candidates of 3-(4-(thiophen-2-yl)-pyridin/pyran/pyrimidin/pyrazol-2-yl)-1H-indole derivatives (2–12) were designed by pairing the pyridine/pyrane/pyrimidine/pyrazole heterocycles with indole and thiophene to investigate their potential activities as (2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) inhibitors. The purpose of these derivatives’ modification is to create high-efficiency antioxidants, especially against ABTS, as a result of the efficiency of this set of key heterocycles in the inhibition of ROS. Herein, 2D QSAR modeling was performed to recommend the most promising members for further in vitro investigations. Furthermore, the pharmacological assay for antioxidant activity evaluation of the yielded indole-based heterocycles was tested against ABTS (2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid); by utilizing ascorbic acid as the standard. Candidate 10 showed higher antioxidant activity (IC50 = 28.23 μg/mL) than ascorbic acid itself which achieved (IC50 = 30.03 μg/mL). Moreover, molecular docking studies were performed for the newly designed and synthesized drug candidates to propose their mechanism of action as promising cytochrome c peroxidase inhibitors compared to ascorbic acid as a reference standard. Our findings could be promising in the medicinal chemistry scope for further optimization of the newly designed and synthesized compounds regarding the introduced structure-activity relationship study (SAR) in order to get a superior antioxidant lead compound in the near future.

Background: There are studies indicating that aqueous or hydroalcoholic dill extracts showed higher antioxidant activity compared to other fractions. Molecular docking studies would be relevant to get information on the mechanism of action of the phenolic constituents of Anethum graveolens seed extracts as bioactive compounds. Methodology: In order to perform the docking studies of antioxidant activity of phenolic constituents of Anethum graveolens seed extracts, BIOVIA Discovery Studio and AutoDock Vina software were used. Results: The orientation of flavonoids within Hck and CYP2C9 binding sites has been shown to be the main reason for their inhibitory potency. Conclusion: Molecular docking studies indicate that the compounds identified interact with the target enzymes Hck and CYP2C9 at molecular level through their condensed ring systems and hydroxyl substituents and therefore support the antioxidant capacity of the studied phenolic compounds.

A series of new 4-thiazolidinone derivatives of 2-(4-chlorophenyl)-3-(6-(thiophen-2-yl)-4-p-tolyl-4H-1,3-oxazin-2-yl)- thiazolidin-4-one (7h-m) are synthesized because of its wide range of biological activities.1H & 13C NMR, IR studies were applied for the elucidation of all the synthesized compounds. All the synthesized compounds have been tested for antidiabetic and antioxidant activity in vitro method against standard. The analogs 7h-m was evaluated for α-amylase and α-glucosidase inhibitory potential. The structures of all the compounds have been screened for antioxidant activity using DPPH radical scavenging assay, NO scavenging method. Molecular docking studies were accomplished in addition to understand the binding affinity of those compounds with PDBID 2HR7 which showed that the synthesized derivatives bind in the lively binding site of the target protein
