Druce: In silico, in vitro, and in vivo studies Authors: Singh, Garima Abstract: Hydrophilic bioactive compounds are copiously exhibited in aqueous extracts owed to solubility. The study was assigned to assess the ability of phytoconstituents of aqueous pod extract of Prosopis cineraria to inhibit 3-hydroxy-3-methylglutary-coenzyme A (HMG-CoA) reductase activity and regression in atherosclerotic plaque through in vitro, in vivo, and in silico assessments along with phytochemistry of extract. The test extract exhibited 17 leading compounds as examined by Liquid Chromatograph Triple Quadrupole Mass Spectroscope. In vitro assay of test extract showed 78.1% inhibition of HMG-CoA inhibition (IC50 was 0.03 μg/ml). In vivo assessments, hypercholesterolemia was induced by supplementing cholesterol powder and a high-fat diet. The treatment of test extract caused significant (p ≤ 0.001) improvements in the lipid profile and antioxidant levels. Subsequently, the reductions in the atherosclerotic plaque and improved lumen volume were pointedly observed. In silico analyses of molecular docking revealed potent interaction capabilities of cloprostenol with the target protein of HMGR. The interactions were validated through structural simulations of the molecular dynamics such as root mean square fluctuation, the radius of gyration, and solvent accessible surface area. The druggability of potent compounds was also examined. The results revealed that phytoconstituents of the test extract could inhibit HMGR and regress atherosclerotic plaque.

The current study was intended to assess DPP-4(Dipeptidyl Peptidase-4) inhibition mediated antidiabetic effect of phytocompounds of an aqueous fruit extract of Withania coagulans (Stocks) Dunal by in-vitro, in-silico and in-vivo approaches. The phytoconstituents screening was executed by LCMS (Liquid Chromatography with tandem mass spectrometry). The in-vitro and in-vivo, DPP-4 assays were performed by using available kits. The in-vitro DPP-4 activity was inhibited up to 68.3% by the test extract. Accordingly, in-silico determinations of molecular docking, molecular dynamics and pharmacokinetics were performed between the target enzyme DPP-4 and leading phytocompounds. The molecular dynamics authenticated the molecular docking data by crucial parameters of cytosolic milieu by the potential energy, RSMD (Root Mean Square Deviation), RSMF (Root Mean Square Fluctuation), system density, NVT (Number of particles at fixed volume, ensemble) and NPT (Number of particles at fixed pressure, ensemble). Accordingly, ADMET predictions assessed the druggability profile. Subsequently, the course of the test extract and the sitagliptin (positive control), instigated significant (p ≤ 0.001) ameliorations in HOMA indices and the equal of antioxidants in nicotinamide-streptozotocin induced type 2 diabetic animal model. Compassionately, the histopathology represented increased pancreatic cellular mass which caused in restoration of histoarchitectures. It has been concluded that phytoconstituents in W. coagulans aqueous fruit extract can regulate DPP-4, resulting in improved glucose homeostasis and enhanced endocrinal pancreatic cellular mass.

In the present study, in vivo experiments were conducted to determine the physiological responses of tomato (Solanum lycopersicum L.) seedlings by inoculation with an endophytic actinobacterium, Streptomyces thermocarboxydus isolate BPSAC147 under greenhouse conditions. Further, photochemical quantum yield of photosystem II (PSII) (Fv/Fm), photochemical quenching (qP) and non-photochemical (NPQ) were calculated in seedlings inoculated with S. thermocarboxydus (T1) and were compared with control (T0) plants. Furthermore, the electron transport rate (ETR) of PSII exhibited a significant increase in T1 plants, relative to T0 plants. These results indicate that inoculation of tomato seedlings with S. thermocarboxydus had a positive effect on the process of photosynthesis, resulting in enhanced chlorophyll fluorescence parameters due to increased ETR in the thylakoid membrane. GC-MS analysis showed significant differences in the volatile compounds in the different treatments performed under greenhouse conditions. The present study suggests that S. thermocarboxydus can be used as new biocontrol agent to control Fusarium wilt in tomato crops and enhance productivity by enhancing photosynthesis.

Bidens pilosa Linn. var. Radiata (Asteraceae) is well known for its folkloric medicinal use against various diseases from many decades. Mizoram, North East India, has high plant diversity and the use of this plant as herbal medicine is deep rooted in the local tribes. The present study was executed to understand the pharmacological potential of B. pilosa leaves extract.
