Abstract DBC1 (deleted in breast cancer 1) is a human nuclear protein that modulates the activities of various proteins. NAD + (oxidized form nicotinamide adenine dinucleotide) thought to potentially bind Nudix homology domains (NHDs) DBC1, thereby regulating DBC1-PARP1 [poly (adenosine diphosphate–ribose) polymerase] interactions, modulation which may restore DNA repair protect against cancer, radiation, and aging. Therefore, our study comprehensively employed methods including NMR (Nuclear Magnetic Resonance), ITC (isothermal titration calorimetry), genetic mutation, computer biology thoroughly investigate molecular mechanism binding interaction between its precursor NMN with NHD domain (DBC1 354-396 ). The results from indicate likely interacts through hydrogen bonding, affinity nearly twice NMN. key sites are primarily E363 D372. Molecular Docking further revealed importance conventional bonds carbon-hydrogen process. These findings lead better understanding how regulates physiological functions offering guiding principles for development targeted therapies drug research focused on tumor diseases associated DBC1.

Introduction Alzheimer’s disease (AD) is a neurodegenerative disorder that progressively affects the cognitive function and memory of affected person. Unfortunately, only handful effective prevention or treatment options are available today. Microtubule affinity-regulating kinase 4 (MARK4) serine/threonine protein plays critical role in regulating microtubule dynamics facilitating cell division. The dysregulated expression MARK4 has been associated with range diseases, including AD. Methods In this study, we synthesized series N -hetarenes via Pd(0)-catalyzed Suzuki-Miyaura cross coupling reaction. All compounds were characterized using multi-spectroscopic techniques evaluated for their activity against enzyme through ATPase inhibition assays. experimental data was further supported by computational quantum chemical calculations. We also computed drug-likeness, bioavailability, toxicity (ADME/T) profiles compounds. Results Six new 4-(6-(arylpyrimidin-4-yl)piperazine-1-carboximidamides 5−10 prepared good yields. assay conducted on these demonstrated IC 50 values micromolar (5.35 ± 0.22 to 16.53 1.71 μM).
