Abstract
Integrin-linked kinase (ILK) is a member of Ser/Thr kinase which interacts to the cytoplasmic domain of β-integrins, and thereby induces apoptosis. ILK is considered as potential drug target because it's direct involvement in the tumor progression. Here, we have performed molecular docking followed by 100 ns MD simulation to understand the mechanism of interaction of ILK with the ellagic acid (EA). EA is well known for its antiproliferative and antioxidant properties in cancer cell lines and animal models. We have observed that EA binds to the active site cavity of ILK and causes conformational changes in the ILK structure. The orientation of EA in the active pocket of ILK showed to have least RMSD values and stable. The average binding energy ILK-EA complex calculated during MMPBSA was -191.267 kJ/mol, indicating a relatively strong binding affinity. The actual binding affinity of EA to ILK was measured by fluorescence spectroscopy and Kb and n values were 9.28 μM and 1.9264 (~2), respectively. The IC50 values for EA were 26.22 ± 0.12 μM for MCF-7 and 38.45 ± 2.42 μM for HepG2 cells, estimated by MTT assay. Our findings are helpful to design EA-based novel inhibitors of ILK which have potential to attenuate tumor progression.

Abstract
Apoptotic evasion by cancerous cells being one of the striking hallmarks of cancer has turned into a new arena of drug discovery. A large number of pathways reported that govern the apoptotic evasion have been reported. Fas-activated serine/threonine kinase (FASTK) is a member of Ser/Thr kinase family, and it has been implicated in the apoptotic evasion and, hence, the development of cancer. Keeping this in view, a series of novel thienopyrimidine-based chalcones have been synthesized and evaluated to modulate the FASTK mediated apoptotic evasion. Initial screening was done by enzyme inhibition assay and binding studies, which showed that out of 15 synthesized compounds, 3 thienopyrimidine-based chalcone derivatives possess considerably high binding affinity and enzyme inhibitory potential (nM range) for FASTK. Cell proliferation assessment of selected compounds was performed on HEK-293 and MCF-7 cells. For MCF-7 cells, compounds 2, 10, and 12 show IC50 values of 20.22 ± 1.50, 6.52 ± 0.82, and 8.20 ± 0.61 μM, respectively. Annexin-V and PI staining suggested that these molecules induce apoptosis in MCF-7 cells, arrest the cell cycle in the G0/G1 phase, and subsequently inhibit cell migration presumably by inhibiting FASTK and reactive oxygen species production. In conclusion, we have successfully designed, synthesized, and characterized thienopyrimidine-based chalcones that inhibit FASTK and induce apoptosis. These compounds may be exploited as potential anticancer agents.

Abstract
Microtubule affinity-regulating kinase 4 (MARK4) has recently been identified as a potential drug target for several complex diseases including cancer, diabetes and neurodegenerative disorders. Inhibition of MARK4 activity is an appealing therapeutic option to treat such diseases. Here, we have performed structure-based virtual high-throughput screening of 100,000 naturally occurring compounds from ZINC database against MARK4 to find its potential inhibitors. The resulted hits were selected, based on the binding affinities, docking scores and selectivity. Further, binding energy calculation, Lipinski filtration and ADMET prediction were carried out to find safe and better hits against MARK4. Best 10 compounds bearing high specificity and binding efficiency were selected, and their binding pattern to MARK4 was analyzed in detail. Finally, 100 ns molecular dynamics simulation was performed to evaluate; the dynamics stability of MARK4-compound complex. In conclusion, these selected natural compounds from ZINC database might be potential leads against MARK4, and can further be exploited in drug design and development for associated diseases.

Abstract
BACKGROUND Hypoxia-ischemia (HI) results in increased activation of Ca2+/calmodulin kinase IV (CaM kinase IV) mediated by Src kinase. Therapeutic hypothermia ameliorates neuronal injury in the newborn. HYPOTHESIS Inhibition of Src kinase concurrently with hypothermia further attenuates the hypoxia-induced increased activation of CaM kinase IV compared with hypothermia alone. DESIGN/METHODS Ventilated piglets were exposed to HI, received saline or a selective Src kinase inhibitor (PP2), and were cooled to 33°C. Neuropathology, adenosine triphosphate (ATP) and phosphocreatine (PCr) concentrations, and CaM kinase IV activity were determined. RESULTS The neuropathology mean score (mean ± SD) was 0.4 ± 0.43 in normoxia-normothermia (p < 0.05 vs. hypoxia-normothermia), 3.5 ± 0.89 in hypoxia-normothermia (p < 0.05 vs. normoxia-normothermia), 0.7 ± 0.73 in hypoxia-hypothermia (p < 0.05 vs. normoxia-normothermia), and 0.5 ± 0.70 in normoxia-hypothermia (p < 0.05 vs. hypoxia-normothermia). The CaM kinase IV activity in cerebral tissue (pmol Pi/mg protein/min; mean ± SD) was 2,002 ± 729 in normoxia-normothermia, 1,704 ± 18 in normoxia-hypothermia, 6,017 ± 2,510 in hypoxia-normothermia, 4,104 ± 542 in hypoxia-hypothermia (p < 0.05 vs. normoxia-hypothermia), and 2,165 ± 415 in hypoxia-hypothermia with PP2 (p < 0.05 vs. hypoxia-hypothermia). The hypoxic groups with and without hypothermia or Src kinase inhibitor were comparable in the levels of ATP and PCr, indicating that they were similar in their degree of energy failure prior to treatments. Hypothermia or Src kinase inhibitor (PP2) did not restore the ATP and PCr levels. CONCLUSIONS Hypothermia and Src kinase inhibition attenuated apoptotic cell death and improved neuropathology after hypoxia. The combination of short-duration hypothermia with Src kinase inhibition following hypoxia further attenuates the increased activation of CaM kinase IV compared to hypothermia alone in the newborn swine brain.

Abstract
Microtubule affinity regulating kinase 4 (MARK4) is a member of AMP-activated protein kinase, found to be involved in apoptosis, inflammation and many other regulatory pathways. Since, its aberrant expression is directly associated with the cell cycle and thus cancer. Therefore, MARK4 is being considered as a potential drug target for cancer therapy. Here, we investigated the mechanism of inhibition of MARK4 activity by citral. Docking studies suggested that citral effectively binds to the active site cavity, and complex is stabilized by several interactions. We further performed molecular dynamics simulation of MARK4-citral complex under explicit water condition for 100ns and observed that binding of citral to MARK4 was quite stable. Fluorescence binding studies suggested that citral strongly binds to MARK4 and thereby inhibits its enzyme activity which was measured by the kinase inhibition assay. We further performed MTT assay and observed that citral inhibits proliferation of breast cancer cell line MCF-7. This work provides a newer insight into the use of citral as novel cancer therapeutics through the MARK4 inhibition. Results may be employed to design novel therapeutic molecule using citral as a scaffold for MARK4 inhibition to fight related diseases.

Abstract
Microtubule affinity regulating kinase 4 (MARK4) is a Ser/Thr kinase belonging to AMPK-like family, has recently become an important drug target against cancer and neurodegenerative disorders. In this study, we have evaluated different natural dietary polyphenolics including rutin, quercetin, ferulic acid, hesperidin, gallic acid and vanillin as MARK4 inhibitors. All compounds are primarily binds to the active site cavity of MARK4. In silico observations were further complemented by the fluorescence-binding studies and isothermal titration calorimetry (ITC) measurements. We found that rutin and vanillin bind to MARK4 with a reasonably high affinity. ATPase and tau-phosphorylation assay further suggesting that rutin and vanillin inhibit the enzyme activity of MARK4 to a great extent. Cell proliferation, ROS quantification and Annexin-V staining studies are clearly providing sufficient evidences for the apoptotic potential of rutin and vanillin. In conclusion, rutin and vanillin may be considered as potential inhibitors for MARK4 and further exploited to design novel therapeutic molecules against MARK4 associated diseases.

Abstract
Human calcium/calmodulin-dependent protein kinase IV (CAMKIV) is a member of Ser/Thr kinase family, and is associated with different types of cancer and neurodegenerative diseases. Vanillin is a natural compound, a primary component of the extract of the vanilla bean which possesses varieties of pharmacological features including anti-oxidant, anti-inflammatory, anti-bacterial and anti-tumor. Here, we have investigated the binding mechanism and affinity of vanillin to the CAMKIV which is being considered as a potential drug target for cancer and neurodegenerative diseases. We found that vanillin binds strongly to the active site cavity of CAMKIV and stabilized by a large number of non-covalent interactions. We explored the utility of vanillin as anti-cancer agent and found that it inhibits the proliferation of human hepatocyte carcinoma (HepG2) and neuroblastoma (SH-SY5Y) cells in a dose-dependent manner. Furthermore, vanillin treatment resulted into the significant reduction in the mitochondrial membrane depolarization and ROS production that eventually leads to apoptosis in HepG2 and SH-SY5Y cancer cells. These findings may offer a novel therapeutic approach by targeting the CAMKIV using natural product and its derivative with a minimal side effect.
