Mainly sight saw in cancer chemotherapeutics, HDAC inhibitors have also found a promising role in other diseases (neurodegenerative disorders, cardiovascular diseases, and viral infections) and successfully entered in various combination therapies (pre-clinical/clinical stages). The prevalent flexibility in the structural design of HDAC inhibitors makes them easily tuneable to merge with other pharmacophore modules for generating multi-targeted single hybrids as a novel tactic to overcome drawbacks of polypharmacy. Herein, we reviewed the putative role of prevalent HDAC hybrids inhibitors in the current and prospective stage as a translational approach to overcome the limitations of the existing conventional drug candidates (parent molecule) when used either alone (drug resistance, solubility issues, adverse side effects, selectivity profile) or in combination (pharmacokinetic interactions, patient compliance) for treating various diseases. The aim of this study was to investigate the relationship of chronic REM-sleep deprivation with laryngopharyngeal reflux (LPR) and its mechanism. Forty healthy male SD rats (body weight 250-280g) were randomly divided into four groups. The first three ones were test group, which underwent REM-sleep deprivation with different duration of time by modified multiplatform water surface method. The last group was the control one having normal sleep. All the animals were performed Dx-pH monitoring when finishing sleep deprivation, and sacrificed to study the gastric residual rate (GRR) and small intestine peristalsis (SPR) rate by charcoal meal method. At prone position, the reflux incidence in the test groups fairly increased with the duration of sleep deprivation (p<0.05).
