• W4311573186 abstract "The cellular environment is densely crowded, confining biomacromolecules including proteins to less available space. This macromolecular confinement may affect the physiological conformation of proteins in long-term processes like ageing. Changes in physiological protein structure can lead to protein conformational disorders including neurodegeneration. An intervention approach using food and plant derived bioflavonoids offered a way to find a treatment for these enervating pathological conditions as there is no remedy available. The bioflavonoids NAR (naringenin), 7HD (7 hydroxyflavanone) and CHR (chrysin) were tested for their ability to protect Hb (hemoglobin) against crowding-induced aggregation. Morphological and secondary structural transitions were studied using microscopic and circular dichroism experiments, respectively. The kinetic study was carried out using the relative thioflavin T assay. Molecular docking, AmylPred2, admetSAR and FRET were applied to understand the binding parameters of bioflavonoids with Hb and their drug likeliness. Isolated human lymphocytes were used as a cellular system to study the toxic effects of Hb aggregates. Redox perturbation and cytotoxicity were evaluated by DCFH-DA and MTT assays, respectively. This study suggests that bioflavonoids bind to Hb in the vicinity of aggregation prone amino acid sequences. Binding of the bioflavonoids stabilizes the Hb against crowding-induced structural alterations. Therefore, this study signifies the potential of bioflavonoids for future treatment of many proteopathies including neurodegeneration.Communicated by Ramaswamy H. Sarma" @default.
