Sphingosine kinase 1 (SphK1) has recently gained attention as a potential drug target for its association with cancer and other inflammatory diseases. Here, we have investigated the binding affinity of dietary phytochemicals viz., ursolic acid, capsaicin, DL-α tocopherol acetate, quercetin, vanillin, citral, limonin simvastatin SphK1. Docking studies revealed that all these compounds bind to SphK1 varying affinities. Fluorescence isothermal titration calorimetric measurements suggested...
Natural-based drugs are believed to be safe, effective and economical. Based on the medicinal importance of genus Eryngium unexplored nature caeruleum , we have evaluated its antidiabetic antioxidant potentials. Both in-vitro in-vivo assays been carried out for assays. The activity was determined by using different free radicals [i.e., 1,1-diphenyl,2-picrylhydrazyl (DPPH), 2,2-azinobis[3-ethylbenzthiazoline]-6-sulfonic acid (ABTS), hydrogen peroxide (H 2 O )]. Moreover, phytoconstituents...

In this study, ultrasound-assisted extraction conditions were optimized to maximize the yields of sennoside A, B, aloe-emodin, emodin, and chrysophanol from S. alexandrina (aerial parts). The three UAE factors, temperature (S1), time (S2), liquid solid ratio (S3), using response surface methodology (RSM). A Box-Behnken design was used for experimental phytoconstituent analysis performed high-performance chromatography-UV. optimal found be a 64.2 °C temperature, 52.1 min time, 25.2 mL/g...
In North Africa, Tetranychus urticae Koch, 1836 represents one of the most destructive generalists among mite herbivores. Unfortunately, it is a source important annual casualties in crop production. It phytophagous that can feed on hundreds host plants and produces significant damage. The control T. Africa has been principally based acaricide sprays. However, new alternative methods have shown effective results, such as artificial ultraviolet-B, natural enemies, introduction genetic...
Breast cancer is a disease characterized by the uncontrolled proliferation of malignant cells in breast tissue, and oxidative stress activated an accumulation reactive oxygen species (ROS) associated with its development progression. Essential oils from medicinal plants, known for their antioxidant therapeutic properties, are being explored as alternatives. Ptychotis verticillata, also Nûnkha, plant native to Morocco, belonging Apiaceae family, used generations traditional medicine. This...
