<p><a>The over expression of Tumor necrosis factor-α (TNFα) has been implicated in a variety of disease and is classified as a therapeutic target for inflammatory diseases (Crohn disease, psoriasis, psoriatic arthritis, rheumatoid arthritis).Commercially available therapeutics are biologics which are associated with several risks and limitations. Small molecule inhibitors and natural compounds (saponins) were identified by researchers as lead molecules against TNFα, however, </a>they were often associated with high IC50 values which can lead to their failure in clinical trials. This warrants research related to identification of better small molecule inhibitors by screening of large compound libraries. Recent developments have demonstrated power of natural compounds as safe therapeutics, hence, in this work, we have identified TNFα phytochemical inhibitors using high throughput <i>in silico </i>screening approaches of 6000 phytochemicals followed by 200 ns molecular dynamics simulations and relative binding free energy calculations. The work yielded potent hits that bind to TNFα at its dimer interface. The mechanism targeted was inhibition of oligomerization of TNFα upon phytochemical binding to restrict its interaction with TNF-R1 receptor. MD simulation analysis resulted in identification of two phytochemicals that showed stable protein-ligand conformations over time. The two compounds were triterpenoids: Momordicilin and Nimbolin A with relative binding energy- calculated by MM/PBSA to be -190.5 kJ/Mol and -188.03 kJ/Mol respectively. Therefore, through this work it is being suggested that these phytochemicals can be used for further <i>in vitro</i> analysis to confirm their inhibitory action against TNFα or can be used as scaffolds to arrive at better drug candidates.</p>

STK15/Aurora2 is a centrosome-associated serine/threonine kinase, the protein levels and kinase activity of which rise during G2 and mitosis. STK15 overexpression induces tumorigenesis and is amplified in various human cancers and tumor cell lines. Thus, STK15 represents an important therapeutic target for small molecule inhibitors that would disrupt its activity and block cell proliferation. The availability of a robust and selective small molecule inhibitor would also provide a useful tool for identification of the potential role of STK15 in cell cycle regulation and tumor development. The authors report the development of a novel, fast, simple microplate assay for STK15 activity suitable for high-throughput screening. In the assay, γ-33P-ATP and STK15 were incubated in a myelin basic protein (MBP)-coated FlashPlate® to generate a scintillation signal. The assay was reproducible, the signal-to-noise ratio was high (11) and the Z′ factor was 0.69. The assay was easily adapted to a robotic system for drug discovery programs targeting STK15. The authors also demonstrate that STK15 is regulated by phosphorylation and the N-amino terminal domain of the protein. Treatment with phosphatase inhibitors (okadaic acid) or deletion of the N-amino terminal domain results in a significant increase in the enzymatic activity.
