Amyloid Diseases

The formation of amyloid aggregates is a feature of most, if not all, polypeptide chains. In vivo modelling of this process has been undertaken in the fruitfly Drosophila melanogaster with remarkable success. Models of both neurological and systemic amyloid diseases have been generated and have informed our understanding of disease pathogenesis in two main ways. First, the toxic amyloid species have been at least partially characterized, for example in the case of the Aβ (amyloid β-peptide) associated with Alzheimer's disease. Secondly, the genetic underpinning of model disease-linked phenotypes has been characterized for a number of neurodegenerative disorders. The current challenge is to integrate our understanding of disease-linked processes in the fly with our growing knowledge of human disease, for the benefit of patients.

Risk Of Aspiration

Abstract Dysphagia is a common disorder associated with a large number of etiologies like aging, stroke, traumatic brain injury, head and neck cancer, neurodegenerative disorders, structural changes or congenital abnormalities. The type of the treatment and its results depend on the type, severity and the cause of dysphagia. The primary goal of dysphagia treatment is to improve the swallowing process and decrease the risk of aspiration. Along with the existing rehabilitation swallowing treatments, new adjunctive therapy options developed, one of them being the neuromuscular electrical stimulation (NMES). The authors present the principles of NMES, a small literature review about the results of this therapy and their experience in using transcutaneous NMES in dysphagia patients.

Metabolic Instability

A set of novel Kv7.2/7.3 (KCNQ2/3) channel blockers was synthesized to address several liabilities of the known compounds XE991 (metabolic instability and CYP inhibition) and the clinical compound DMP 543 (acid instability, insolubility, and lipophilicity). Using the anthrone scaffold of the prior channel blockers, alternative heteroarylmethyl substituents were installed via enolate alkylation reactions. Incorporation of a pyridazine and a fluorinated pyridine gave an analog (JDP-107) with an optimal combination of potency (IC<sub>50</sub>= 0.16 𝜇M in a Kv7.2 thallium flux assay), efficacy in a Kv7.2/7.3 patch clamp assay, and drug-like properties.

Effective Treatments

Neurodegenerative disorders (NDDs) like Alzheimer's disease, Parkinson’s disease and Huntington’s disease are a heterogeneous group of disorders with the progressive and severe loss of neurons. There are no full proof cures for these diseases, and only medicines are available that can alleviate some of the symptoms. Developing effective treatments for the NDDs is a difficult but necessary task. Hence, the investigation of monoterpenoids which modulate targets applicable to many NDDs is highly relevant. Many monoterpenoids have demonstrated promising neuroprotective activity mediated by various systems. It can form the basis for elaboration of agents which will be useful both for the alleviation of symptoms of NDDs and for the treatment of diseases progression and also for prevention of neurodegeneration. The further developments including detections of monoterpenoids and their derivatives with high neuroprotective or neurotrophic activity as well as the results of qualified clinical trials are needed to draw solid conclusions regarding the efficacy of these agents.
