Abstract
Alzheimer's and Parkinson's are neurodegenerative disorders that affect a great number of people around the world, seriously compromising the quality of life of individuals, due to motor and cognitive damage. In these diseases, pharmacological treatment is used only to alleviate symptoms. This emphasizes the need to discover alternative molecules for use in prevention. Using Molecular Docking, this review aimed to evaluate the anti-Alzheimer's and anti-Parkinson's activity of linalool and citronellal, as well as their derivatives. Before performing Molecular Docking simulations, the compounds' pharmacokinetic characteristics were evaluated. For Molecular Docking, 7 chemical compounds derived from citronellal, and 10 compounds derived from linalool, and molecular targets involved in Alzheimer's and Parkinson's pathophysiology were selected. According to the Lipinski rules, the compounds under study presented good oral absorption and bioavailability. For toxicity, some tissue irritability was observed. For Parkinson-related targets, the citronellal and linalool derived compounds revealed excellent energetic affinity for α-Synuclein, Adenosine Receptors, Monoamine Oxidase (MAO), and Dopamine D1 receptor proteins. For Alzheimer disease targets, only linalool and its derivatives presented promise against BACE enzyme activity. The compounds studied presented high probability of modulatory activity against the disease targets under study, and are potential candidates for future drugs.

Degradation and inhibition of epigenetic regulatory protein BRD4 exacerbate Alzheimer's disease-related neuropathology in cell models. J Biol Chem 2022; 298:101794. [PMID: 35248531 PMCID: PMC8958546 DOI: 10.1016/j.jbc.2022.101794] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Revised: 02/22/2022] [Accepted: 02/23/2022] [Indexed: 12/12/2022] Open
Abstract
Epigenetic regulation plays substantial roles in human pathophysiology, which provides opportunities for intervention in human disorders through the targeting of epigenetic pathways. Recently, emerging evidence from preclinical studies suggested the potential in developing therapeutics of Alzheimer's disease (AD) by targeting bromodomain containing protein 4 (BRD4), an epigenetic regulatory protein. However, further characterization of AD-related pathological events is urgently required. Here, we investigated the effects of pharmacological degradation or inhibition of BRD4 on AD cell models. Interestingly, we found that both degradation and inhibition of BRD4 by ARV-825 and JQ1, respectively, robustly increased the levels of amyloid-beta (Aβ), which has been associated with the neuropathology of AD. Subsequently, we characterized the mechanisms by which downregulation of BRD4 increases Aβ levels. We found that both degradation and inhibition of BRD4 increased the levels of BACE1, the enzyme responsible for cleavage of the amyloid-beta protein precursor (APP) to generate Aβ. Consistent with Aβ increase, we also found that downregulation of BRD4 increased AD-related phosphorylated Tau (pTau) protein in our 3D-AD human neural cell culture model. Therefore, our results suggest that downregulation of BRD4 would not be a viable strategy for AD intervention. Collectively, our study not only shows that BRD4 is a novel epigenetic component that regulates BACE1 and Aβ levels, but also provides novel and translational insights into the targeting of BRD4 for potential clinical applications.

Nanodelivery of oxiracetam enhances memory, functional recovery and induces neuroprotection following concussive head injury. PROGRESS IN BRAIN RESEARCH 2021; 265:139-230.

Abstract
Military personnel are the most susceptible to concussive head injury (CHI) caused by explosion, blast or missile or blunt head trauma. Mild to moderate CHI could induce lifetime functional and cognitive disturbances causing significant decrease in quality of life. Severe CHI leads to instant death and lifetime paralysis. Thus, further exploration of novel therapeutic agents or new features of known pharmacological agents are needed to enhance quality of life of CHI victims. Previous reports from our laboratory showed that mild CHI induced by weight drop technique causing an impact of 0.224N results in profound progressive functional deficit, memory impairment and brain pathology from 5h after trauma that continued over several weeks of injury. In this investigation we report that TiO2 nanowired delivery of oxiracetam (50mg/kg, i.p.) daily for 5 days after CHI resulted in significant improvement of functional deficit on the 8th day. This was observed using Rota Rod treadmill, memory improvement assessed by the time spent in finding hidden platform under water. The motor function improvement is seen in oxiracetam treated CHI group by placing forepaw on an inclined mesh walking and foot print analysis for stride length and distance between hind feet. TiO2-nanowired oxiracetam also induced marked improvements in the cerebral blood flow, reduction in the BBB breakdown and edema formation as well as neuroprotection of neuronal, glial and myelin damages caused by CHI at light and electron microscopy on the 7th day after 5 days TiO2 oxiracetam treatment. Adverse biochemical events such as upregulation of CSF nitrite and nitrate, IL-6, TNF-a and p-Tau are also reduced significantly in oxiracetam treated CHI group. On the other hand post treatment of 100mg/kg dose of normal oxiracetam in identical conditions after CHI is needed to show slight but significant neuroprotection together with mild recovery of memory function and functional deficits on the 8th day. These observations are the first to point out that nanowired delivery of oxiracetam has superior neuroprotective ability in CHI. These results indicate a promising clinical future of TiO2 oxiracetam in treating CHI patients for better quality of life and neurorehabilitation, not reported earlier.

Abstract
BACKGROUND The complication of Alzheimer's disease (AD) has made the development of its therapeutic a challenging task. Even after decades of research, we have achieved no more than a few years of symptomatic relief. The inability to diagnose the disease early is the foremost hurdle behind its treatment. Several studies have aimed to identify potential biomarkers that can be detected in body fluids (CSF, blood, urine, etc) or assessed by neuroimaging (i.e., PET and MRI). However, the clinical implementation of these biomarkers is incomplete as they cannot be validated. METHOD To overcome the limitation, the use of artificial intelligence along with technical tools has been extensively investigated for AD diagnosis. For developing a promising artificial intelligence strategy that can diagnose AD early, it is critical to supervise neuropsychological outcomes and imaging-based readouts with a proper clinical review. CONCLUSION Profound knowledge, a large data pool, and detailed investigations are required for the successful implementation of this tool. This review will enlighten various aspects of early diagnosis of AD using artificial intelligence.

Abstract
BACKGROUND An increasing number of newborn children in numerous nations are enrolled in early childhood education programs, and instructors, in this way, assume a focal job in invigorating language improvement in these youthful kids. Kids with language issues are found to have a higher risk for future scholarly challenges and learning inabilities. Language advancement among kids is an intricate procedure and vital for correspondence. The shortcomings in the utilization of grammatical structures may lessen the useful utilization of language for verbally expressive kids with autism spectrum disorder and exacerbate troubles with academic and social expertise advancement. RESULTS FOXP2, the single principal gene connected to a speech and language issue, is significant for the right execution of complex motor behaviors used for speech. In any case, changes in FOXP2 lead to a speech/language issue portrayed by childhood apraxia of speech. These days, language learning is fundamentally required for kids who need to move to different nations to pursue the instructive frameworks and be helpful individuals or residents of those nations. CONCLUSION The purpose of this study was to explore the role of FOXP2 in language disorder and its management for children's language and communication development.

Abstract
AIM Poor nutritional effect of junk food induces injurious adversities to the liver and brain but still most of the developing nations survives on these diets to compensate for fast-paced lifestyle. Aim of the study is to infer the proteinconnections behind liver-brain axis and identify the role of these proteins in causing neurodegenerative disorders. BACKGROUND Chronic consumption of fructose and fat rich food works as a toxin in body and have the ability to cause negative metabolic shift. Recently a study was published in Annals of Internal Medicine (2019) citing the loss of vision and hearing in a 14-year-old boy whose diet was strictly restricted to fries and junk-food for almost a decade. This puts the entire body on insulin resistance and related co-morbidities and causes simultaneous damaging effects in liver as well brain. This work provides insights into liver-brain axis and explains how liver is involved in brain related disorders. OBJECTIVE In this study transcriptomic data relating to chronic eating of junk-food was analyzed and simultaneous damage that happens in liver and brain was assessed at molecular level. METHOD Transcriptomic study was taken from GEO database and analysed to find out the genes dysregulated in both liver and brain during this metabolic stress. Cytoscapev3.7 was used to decipher the signalling between liver and brain. This connection between both was called as Liver-Brain axis. RESULT The results obtained from our study indicates the role of TUBB5-HYOU1-SDF2L1-DECR1-CDH1-EGFR-SKP2- SOD1-IRAK1-FOXO1 gene signature towards the decline of concurrent liver and brain health. Dysregulated levels of these genes are linked to molecular processes like cellular senescence, hypoxia, glutathione synthesis, amino acid modification, increased nitrogen content, synthesis of BCAAs, cholesterol biosynthesis, steroid hormone signalling and VEGF pathway. CONCLUSION We strongly advocate that prolonged consumption of junk food is a major culprit in brain related disorders like Alzheimer's disease and propose that receptors for brain diseases lie outside the brain and aiming them for drug discovery and design may be beneficial in future clinical studies. This study also discusses the connection between NAFLD (nonalcoholic fatty liver disease) and sAD (sporadic Alzheimer's disease) owing to liver-brain axis.

Abstract
Alzheimer's disease is a neuropathological disease with symptoms such as language problems,
confusion as to place or time, loss of interest in activities, which were previously enjoyed, behavioral
changes, and memory loss. Alzheimer's disease and other types of dementia affect almost
46.8 million people globally and are estimated to strike about 131.5 million people in 2050. It has been
reported that Alzheimer's is the sixth main cause of mortality. The most used drugs, which are currently
approved by the Food, and Drug Administration for Alzheimer’s disease are donepezil, rivastigmine,
galantamine, memantine, and the combination of donepezil and memantine. However, most of
the drugs present various adverse effects. Recently, the transdermal drug delivery route has gained increasing
attention as an emerging tool for Alzheimer's disease management. Besides, transdermal drug
delivery systems seem to provide hope for the management of various diseases, due to the advantages
that they offer in comparison with oral dosage forms. Herein, the current advancements in transdermal
studies with potent features to achieve better Alzheimer's disease management are presented. Many
researchers have shown that the transdermal systems provide higher efficiency since the first-pass hepatic
metabolism effect can be avoided and a prolonged drug release rate can be achieved. In summary,
the transdermal administration of Alzheimer's drugs is an interesting and promising topic, which
should be further elaborated and studied.

Abstract
Scopolamine as a drug is often used to treat motion sickness. Derivatives of scopolamine
have also found applications as antispasmodic drugs among others. In neuroscience-related research, it
is often used to induce cognitive disorders in experimental models as it readily permeates the bloodbrain
barrier. In the context of Alzheimer’s disease, its effects include causing cholinergic dysfunction
and increasing amyloid-β deposition, both of which are hallmarks of the disease. Hence, the application
of scopolamine in Alzheimer’s disease research is proven pivotal but seldom discussed. In this review,
the relationship between scopolamine and Alzheimer’s disease will be delineated through an
overall effect of scopolamine administration and its specific mechanisms of action, discussing mainly
its influences on cholinergic function and amyloid cascade. The validity of scopolamine as a model of
cognitive impairment or neurotoxin model will also be discussed in terms of advantages and limitations
with future insights.

Abstract
The interlink between diabetes mellitus and neurodegenerative diseases such as Alzheimer's Disease (AD) and Parkinson's Disease (PD) has been identified by several researchers. Patients with Type-2 Diabetes Mellitus (T2DM) are found to be affected with cognitive impairments leading to learning and memory deficit, while patients with Type-1 Diabetes Mellitus (T1DM) showed less severe levels of these impairments in the brain. This review aimed to discuss the connection between insulin with the pathophysiology of neurodegenerative diseases (AD and PD) and the current therapeutic approached mediated through insulin for management of neurodegenerative diseases. An extensive literature search was conducted using keywords "insulin"; "insulin resistance"; "Alzheimer's disease"; "Parkinson's disease" in public domains of Google scholar, PubMed, and ScienceDirect. Selected articles were used to construct this review. Studies have shown that impaired insulin signaling contributes to the accumulation of amyloid-β, neurofibrillary tangles, tau proteins and α-synuclein in the brain. Whereas, improvement in insulin signaling slows down the progression of cognitive decline. Various therapeutic approaches for altering the insulin function in the brain have been researched. Besides intranasal insulin, other therapeutics like PPAR-γ agonists, neurotrophins, stem cell therapy and insulin-like growth factor-1 are under investigation. Research has shown that insulin insensitivity in T2DM leads to neurodegeneration through mechanisms involving a variety of extracellular, membrane receptor, and intracellular signaling pathway disruptions. Some therapeutics, such as intranasal administration of insulin and neuroactive substances have shown promise but face problems related to genetic background, accessibility to the brain, and invasiveness of the procedures.

Abstract
INTRODUCTION In spite of the steady progress in the understanding of the etiopathogenesis of Alzheimer's Disease (AD) for the last 50 years, exceptionally few long-standing drugs are, at present, used for AD therapy. New interventions that either prevent, slow or stop the disease are urgently warranted to overcome the growing AD burden. The aim of this narrative review is to summarize the currently existing preclinical and clinical evidence regarding new drug development and biomarkers for better understanding and focused management of AD. This article reviews the various potential and existing targets /receptors with valid biomarkers applied in recent years to address the early-stage tasks of the AD drug discovery process. A comprehensive literature search was conducted in the relevant databases to identify studies published in recent years. In conclusion, the new approaches seem to aim at examining the prospective neuroprotective activity of disease-modifying drugs in the presymptomatic phases of AD, using biomarkers that detect progression of the disease before the growth of overt dementia.

Abstract
BACKGROUND Alzheimer's disease (AD) is considered a severe, irreversible and progressive neurodegenerative disorder. Currently, the pharmacological management of AD is based on a few clinically approved acethylcholinesterase (AChE) and N-methyl-D-aspartate (NMDA) receptor ligands, with unclear molecular mechanisms and severe side effects. METHODS Here, we reviewed the most recent bioinformatics, cheminformatics (SAR, drug design, molecular docking, friendly databases, ADME-Tox) and experimental data on relevant structurebiological activity relationships and molecular mechanisms of some natural and synthetic compounds with possible anti-AD effects (inhibitors of AChE, NMDA receptors, beta-secretase, amyloid beta (Aβ), redox metals) or acting on multiple AD targets at once. We considered: (i) in silico supported by experimental studies regarding the pharmacological potential of natural compounds as resveratrol, natural alkaloids, flavonoids isolated from various plants and donepezil, galantamine, rivastagmine and memantine derivatives, (ii) the most important pharmacokinetic descriptors of natural compounds in comparison with donepezil, memantine and galantamine. RESULTS In silico and experimental methods applied to synthetic compounds led to the identification of new AChE inhibitors, NMDA antagonists, multipotent hybrids targeting different AD processes and metal-organic compounds acting as Aβ inhibitors. Natural compounds appear as multipotent agents, acting on several AD pathways: cholinesterases, NMDA receptors, secretases or Aβ, but their efficiency in vivo and their correct dosage should be determined. CONCLUSION Bioinformatics, cheminformatics and ADME-Tox methods can be very helpful in the quest for an effective anti-AD treatment, allowing the identification of novel drugs, enhancing the druggability of molecular targets and providing a deeper understanding of AD pathological mechanisms.
