Several suggested molecular pathways are reviewed including SOD1 gene mutation, protein nitrosylation, phosphorylation and oxidative stress, excitotoxicity, glutamate transporter deprivation, mitochondrial involvement, protein aggregation and motor neuron trophic factors. The role of insulin and its receptor in the brain is described. It is very possible that in 90% of the sporadic ALS cases, the cause of the motor neuron degeneration is different or that multiple mechanisms are involved that would need drugs with multiple mechanisms or action. Several marketed drugs have been selected for clinical trials. Only two drugs have been approved by the FDA as showing positive effect in ALS: Riluzole and Edaravone. Two other drugs that have a significant benefit in ALS are Talampanel and Tamoxifen. The results for modulation of the neurotrophic factor Insulin Growth Factor-1 (IGF1) as a potential treatment are inconclusive. Several compounds are discussed that show a positive effect in the mouse model but which have failed in clinical trials. New approaches using different modalities such as peptides, proteins and stem cells are promising. Our ability to design better drugs would be enhanced by investigating the endogenous factors in neuron death, protein aggregation and oxidative stress that would improve our understanding of the potential pathways that result in neurodegeneration.","PeriodicalId":20755,"journal":{"name":"Progress in medicinal chemistry","volume":"58 ","pages":"63-117"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/bs.pmch.2018.12.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37063943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The CaR was a challenging target for drug discovery because its physiological ligand is an inorganic ion (Ca2+) rather than a molecule so there was no structural template to guide medicinal chemistry. Nonetheless, small molecules targeting this receptor were discovered. Calcimimetics are agonists or positive allosteric modulators of the CaR, while calcilytics are antagonists and all to date are negative allosteric modulators. The calcimimetic cinacalcet was the first allosteric modulator of a GPCR to achieve regulatory approval and is a first-in-class treatment for secondary hyperparathyroidism in patients on dialysis, and for hypercalcemia in some forms of primary hyperparathyroidism. It is also useful in treating some rare genetic diseases that cause hypercalcemia. Two other calcimimetics are now on the market (etelcalcetide) or under regulatory review (evocalcet). Calcilytics stimulate the secretion of parathyroid hormone and were initially developed as treatments for osteoporosis. Three different calcilytics of two different chemotypes failed in clinical trials due to lack of efficacy. Calcilytics are now being repurposed and might be useful in treating hypoparathyroidism and several rare genetic diseases causing hypocalcemia. The challenges ahead for medicinal chemists are to design compounds that select conformations of the CaR that preferentially target a particular signalling pathway and/or that affect the CaR in a tissue-selective manner.","PeriodicalId":20755,"journal":{"name":"Progress in medicinal chemistry","volume":"57 1","pages":"1-86"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/bs.pmch.2017.12.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36029508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are many problems associated with the data itself including general reproducibility, but often, it is the context surrounding an experiment that is critical to success. Help, in the form of artificial intelligence (AI), is required to understand and translate the context. On the back of natural language processing pipelines, AI is also used to prospectively generate new hypotheses by linking data together.

While different mutations lead to varying levels of disease severity, the most common CFTR F508del mutation leads to defects in protein stability, trafficking to the cell membrane and gating of chloride ions. Recently, advances in medicinal chemistry have led to the identification small-molecule drugs that result in significant clinical efficacy in improving lung function in CF patients. Multiple CFTR modulators are required to fix the various defects in the CFTR protein. Small-molecule potentiators increase the open-channel probability and improve the gating of ions through CFTR. Small-molecule correctors stabilize the protein fold of the mutant channel, facilitating protein maturation and translocation to the cellular membrane. Recent data suggest that triple-combination therapy consisting of a potentiator and two correctors that operate through distinct mechanisms will be required to deliver highly significant clinical efficacy for most CF patients. The progress in medicinal chemistry that has led to the identification of novel CFTR potentiators and correctors is presented in this chapter.","PeriodicalId":20755,"journal":{"name":"Progress in medicinal chemistry","volume":"57 1","pages":"235-276"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/bs.pmch.2018.01.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36029511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dysregulation of this critical monoaminergic system has been associated with diseases of the central nervous system including schizophrenia, Parkinson's disease, and disorders such as attention deficit hyperactivity disorders and addiction. Drugs that modify the dopaminergic system by modulating the activity of dopamine have been successful in demonstrating clinical efficacy by providing treatments for these diseases. Specifically, antipsychotics, both typical and atypical, while acting on a number of monoaminergic systems in the brain, primarily target the dopamine system via inhibition of postsynaptic dopamine receptors. The vesicular monoamine transporter 2 (VMAT2) is an integral presynaptic protein that regulates the packaging and subsequent release of dopamine and other monoamines from neuronal vesicles into the synapse. Despite acting on opposing sides of the synapse, both antipsychotics and VMAT2 inhibitors act to decrease the activity of central dopaminergic systems. Tardive dyskinesia is a disorder characterized by involuntary repetitive movements and thought to be a result of a hyperdopaminergic state precipitated by the use of antipsychotics. Valbenazine (NBI-98854), a novel compound that selectively inhibits VMAT2 through an active metabolite, has been developed for the treatment of tardive dyskinesia and is the first drug approved for the treatment of this disorder. This chapter describes the process leading to the discovery of valbenazine, its pharmacological characteristics, along with preclinical and clinical evidence of its efficacy.","PeriodicalId":20755,"journal":{"name":"Progress in medicinal chemistry","volume":"57 1","pages":"87-111"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/bs.pmch.2017.12.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36032402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
