Brain Histamine and Neuroinflammation INTRODUCTION worldwide, and is expected to rise (Arvidsson et al., 2018). Despite the high prevalence rate, the etiology and pathogenesis ASD as a Prototype for Neuropsychiatric of this disorder are still largely unknown and remain a matter of Disorders speculation. The lack of a specific etiologic diagnosis can be Alzheimer’s disease (AD) patients are often found to show attributed to limited human brain accessibility and the apathy, depression, eating, and sleeping disorders, aggressive complexity of the neurobiology of its activity (Nestler and behavior, as well as other non-cognitive symptoms (Selles Hyman, 2010).ASDisaheterogeneousgroupof et al., 2018). These symptoms are usually associated with AD neurobehavioral abnormalities with different recognized pathology but are often neglected as part of disease progression genetic and environmental origins. Genetic and environmental due to the early and more profound disturbances of memory factors are strongly suggested to be involved in incidence of ASD centers in the hippocampus and entorhinal cortex. AD comprises (Baronio et al., 2015). Additionally, the heterogeneous behavioral up to 80% of all dementias. Behavioral and psychological symptoms and neuropsychiatric comorbidities in autistic symptoms of dementia (BPSD) in AD are known recently to children make it difficult to decipher the pathophysiology of correlate with gray matter (GM) atrophy and, also with white this disorder, and consequently to develop a fundamental matter (WM) damage. WM damage and its relationship with therapeutic approach to ASD. Therefore, subgrouping of ASD GM atrophy are reported in AD (Makovac et al., 2016). children with shared symptoms and shared molecular changes Additionally, Sokol et al. reported that Amyloid-b protein into several categories and observing their response to precursor (bAPP) and its metabolites to be dysregulated not intervention is essential (James et al., 2009). Pharmacological only in AD, but also in Autism spectrum disorder (ASD), and treatments addressing core symptoms in ASD still remain that the secreted variant of APP may lead to increased brain challenging. Despite expanding awareness and advances in WM. WM structure is dynamic and is essential to cognitive early age, efficacious reversal of these persistent autistic function (Courchesne et al., 2003; Dawson et al., 2007). WM is symptoms is not yet achieved. To date, risperidone and largely composed of glia including microglia and it was proposed aripiprazole are the only two ASD-specific drugs approved by that neuroinflammation along with increased myelination, may the US Food and Drug Administration (FDA) for improving contribute more to the WM enlargement in ASD (Herbert, 2005; behavioral ASD associated symptoms, such as irritability Fields, 2008; Aoki et al., 2017; Sokol et al., 2019). (Matson et al., 2011). There is lack of effective therapeutic Neuroinflammation appears to be similar in ASD and AD interventions that address ASD hallmark symptoms (Sheldrick (Herbert, 2005), hence, applying known pathways in AD to and Carter, 2018; Xu et al., 2018). Pharmacotherapeutic options ASD as proposed, should provide drug targets for ASD. that are currently used target accompanying symptoms in ASD, Therefore, knowledge from better developed field as AD opens but are not disease-modifying and do not provide symptomatic the door to better understand ASD. control of core symptoms (Wong and Smith, 2006; Hanson et al., Interestingly, BPSD are present in almost 90% of patients 2007). These accompanying physiological and psychiatric diagnosed with AD, characterized as a disorder of heterogeneous symptoms of ASD include attention deficit, anxiety, irritability, degenerative symptoms with memory and cognitive deficits hyperactivity, self-injuries, aggression, in addition to sleep, considered as the core symptoms across multiple symptom sensory, and gastrointestinal disturbances (Lai et al., 2014; domains (Chakraborty et al., 2019). Many BPSD share Summers et al., 2017). Psychiatric drugs are frequently used for similarities with symptoms observed in AD, schizophrenia treating these symptoms in autistic children (Findling, 2005).

  • From Inverse Agonism to 'Paradoxical Pharmacology' Richard A
    International Congress Series 1249 (2003) 27-37 From inverse agonism to 'Paradoxical Pharmacology' Richard A. Bond*, Kenda L.J. Evans, Zsirzsanna Callaerts-Vegh Department of Pharmacological and Pharmaceutical Sciences, University of Houston, 521 Science and Research Bldg 2, 4800 Caltioun, Houston, TX 77204-5037, USA Received 16 April 2003; accepted 16 April 2003 Abstract The constitutive or spontaneous activity of G protein-coupled receptors (GPCRs) and compounds acting as inverse agonists is a recent but well-established phenomenon. Dozens of receptor subtypes for numerous neurotransmitters and hormones have been shown to posses this property. However, do to the apparently low percentage of receptors in the spontaneously active state, the physiologic relevance of these findings remains questionable. The possibility that the reciprocal nature of the effects of agonists and inverse agonists may extend to cellular signaling is discussed, and that this may account for the beneficial effects of certain p-adrenoceptor inverse agonists in the treatment of heart failure. © 2003 Elsevier Science B.V. All rights reserved. Keywords. Inverse agonism; GPCR; Paradoxical pharmacology 1. Brief history of inverse agonism at G protein-coupled receptors For approximately three-quarters of a century, ligands that interacted with G protein- coupled receptors (GPCRs) were classified either as agonists or antagonists. Receptors were thought to exist in a single quiescent state that could only induce cellular signaling upon agonist binding to the receptor to produce an activated state of the receptor. In this model, antagonists had no cellular signaling ability on their own, but did bind to the receptor and prevented agonists from being able to bind and activate the receptor.

Ramsay3 & H. Stark1 Accepted: 07 December 2016 Ciproxifan is a well-investigated histamine H receptor (H3R) inverse agonist/antagonist, showing Published: 13 January 2017 3 an exclusively high species-specific affinity at rodent compared to human H3R. It is well studied as reference compound for H3R in rodent models for neurological diseases connected with neurotransmitter dysregulation, e.g. attention deficit hyperactivity disorder or Alzheimer’s disease. In a screening for potential monoamine oxidase A and B inhibition ciproxifan showed efficacy on both enzyme isoforms. Further characterization of ciproxifan revealed IC50 values in a micromolar concentration range for human and rat monoamine oxidases with slight preference for monoamine oxidase B in both species. The inhibition by ciproxifan was reversible for both human isoforms. Regarding inhibitory potency of ciproxifan on rat brain MAO, these findings should be considered, when using high doses in rat models for neurological diseases. As the H3R and monoamine oxidases are all capable of affecting neurotransmitter modulation in brain, we consider dual targeting ligands as interesting approach for treatment of neurological disorders. Since ciproxifan shows only moderate activity at human targets, further investigations in animals are not of primary interest. On the other hand, it may serve as starting point for the development of dual targeting ligands. Ciproxifan (cyclopropyl 4-(3-(1H-imidazol-4-yl)propyloxy)phenyl methanone) is a well characterized species-specific histamine 3H receptor (H3R) inverse agonist/antagonist (Fig.

Received: 15 August 2018; Accepted: 17 October 2018; Published: 25 October 2018 Abstract: Autism is a developmental disability that can cause significant emotional, social and behavioral dysfunction. Sleep disorders co-occur in approximately half of the patients with autism spectrum disorder (ASD). Sleep problems in individuals with ASD have also been associated with poor social interaction, increased stereotypy, problems in communication, and overall autistic behavior. Behavioral interventions are considered a primary modality of treatment. There is limited evidence for psychopharmacological treatments in autism; however, these are frequently prescribed. Melatonin, antipsychotics, antidepressants, and α agonists have generally been used with melatonin, having a relatively large body of evidence. Further research and information are needed to guide and individualize treatment for this population group. Keywords: autism spectrum disorder; sleep disorders in ASD; medications for sleep disorders in ASD; comorbidities in ASD 1. Introduction Autism is a developmental disability that can cause significant emotional, social, and behavioral dysfunction. According to the Diagnostic and Statistical Manual (DSM-V) classification [1], autism spectrum disorder (ASD) is characterized by persistent deficits in domains of social communication, social interaction, restricted and repetitive patterns of behavior, interests, or activities.
