There is no definitive cure, but vaccines have greatly protected humans from symptomatic infections and severe complications. However, vaccine efficacy has been greatly reduced by the advent of SARS-CoV-2 variants worldwide. The World Health Organization has classified the variants into two groups: variants of concern (Alpha, Beta, Gamma, Delta, Omicron) and variants of interest (Lambda, Mu). Clinical trials and modifications of vaccines are currently undertaken to improve their clinical efficacies. This is particularly worrying in immunocompromised patients since breakthrough infections with multiple lineages of variants can pose a continuous threat of severe diseases in these vulnerable subjects, though there is no evidence showing immunocompromised patients are at a higher risk of vaccine-associated adverse events. However, there is no consensus on the schedule, benefits, and risks as well as contraindications (both absolute and relative) of receiving booster vaccinations. This review looks into the efficacy and safety of COVID-19 vaccination booster to guide clinical decisions on when and who to receive booster vaccination.","PeriodicalId":73080,"journal":{"name":"Frontiers in drug discovery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45217968","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}

T cell epitopes bind human leukocyte antigen (HLA) by a well-characterized interaction of amino acid side chains and pockets in the HLA molecule binding groove. Immunoinformatics tools, such as the EpiMatrix algorithm, have been developed to screen natural amino acid sequences for peptides that will bind HLA. In addition to commonly occurring in synthetic peptide impurities, unnatural amino acids (UAA) are also often incorporated into novel peptide therapeutics to improve properties of the drug product. To date, the HLA binding properties of peptides containing UAA are not accurately estimated by most algorithms. Both scenarios warrant the need for enhanced predictive tools. The authors developed an <i>in silico</i> method for modeling the impact of a given UAA on a peptide's likelihood of binding to HLA and, by extension, its immunogenic potential. <i>In silico</i> assessment of immunogenic potential allows for risk-based selection of best candidate peptides in further confirmatory <i>in vitro, ex vivo</i> and <i>in vivo</i> assays, thereby reducing the overall cost of immunogenicity evaluation. Examples demonstrating <i>in silico</i> immunogenicity prediction for product impurities that are commonly found in formulations of the generic peptides teriparatide and semaglutide are provided. Next, this article discusses how HLA binding studies can be used to estimate the binding potentials of commonly encountered UAA and \"correct\" <i>in silico</i> estimates of binding based on their naturally occurring counterparts. As demonstrated here, these in vitro binding studies are usually performed with known ligands which have been modified to contain UAA in HLA anchor positions.

Most mainstay treatments currently on the market only alleviate specific symptoms and do not reverse disease progression. The Pituitary adenylate cyclase-activating polypeptide (PACAP), an endogenous neuropeptide hormone, has been extensively studied as a potential regenerative therapeutic. PACAP is widely distributed in the central nervous system (CNS) and exerts its neuroprotective and neurotrophic effects via the related Class B GPCRs PAC1, VPAC1, and VPAC2, at which the hormone shows roughly equal activity. Vasoactive intestinal peptide (VIP) also activates these receptors, and this close analogue of PACAP has also shown to promote neuronal survival in various animal models of acute and progressive neurodegenerative diseases. However, PACAP’s poor pharmacokinetic profile (non-linear PK/PD), and more importantly its limited blood-brain barrier (BBB) permeability has hampered development of this peptide as a therapeutic. We have demonstrated that glycosylation of PACAP and related peptides promotes penetration of the BBB and improves PK properties while retaining efficacy and potency in the low nanomolar range at its target receptors. Furthermore, judicious structure-activity relationship (SAR) studies revealed key motifs that can be modulated to afford compounds with diverse selectivity profiles. Most importantly, we have demonstrated that select PACAP glycopeptide analogues (2LS80Mel and 2LS98Lac) exert potent neuroprotective effects and anti-inflammatory activity in animal models of traumatic brain injury and in a mild-toxin lesion model of Parkinson’s disease, highlighting glycosylation as a viable strategy for converting endogenous peptides into robust and efficacious drug candidates.","PeriodicalId":73080,"journal":{"name":"Frontiers in drug discovery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47903086","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}

Over the course of the disease, progressive paralysis takes place, leading to patient death within 3–5 years after the diagnosis. Despite decades of intensive research, only a few therapeutic options exist, with a limited benefit on the disease progression. Preclinical animal models have been very useful to decipher some aspects of the mechanisms underlying ALS. However, discoveries made using transgenic animal models have failed to translate into clinically meaningful therapeutic strategies. Thus, there is an urgent need to find solutions to discover drugs that could impact on the course of the disease, with the ultimate goal to extend the life of patients and improve their quality of life. Induced pluripotent stem cells (iPSCs), similarly to embryonic stem cells (ESCs), have the capacity to differentiate into all three embryonic germ layers, which offers the unprecedented opportunity to access patient-specific central nervous system cells in an inexhaustible manner. Human MNs generated from ALS patient iPSCs are an exciting tool for disease modelling and drug discovery projects, since they display ALS-specific phenotypes. Here, we attempted to review almost 2 decades of research in the field, first highlighting the steps required to efficiently generate MNs from human ESCs and iPSCs. Then, we address relevant ALS studies which employed human ESCs and iPSC-derived MNs that led to the identification of compounds currently being tested in clinical trials for ALS. Finally, we discuss the potential and caveats of using patient iPSC-derived MNs as a platform for drug screening, and anticipate ongoing and future challenges in ALS drug discovery.","PeriodicalId":73080,"journal":{"name":"Frontiers in drug discovery","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44059252","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}

CADD has largely contributed to identifying and optimizing hit compounds leading them to advanced stages of the drug discovery pipeline or the market (PrietoMartínez et al., 2019). CADD includes several theoretical disciplines, including chemoinformatics, bioinformatics, molecular modeling, and data mining, among others (López-López et al., 2021). Artificial intelligence (AI) that has been used since the 60 s (Gasteiger, 2020) in drug discovery is regaining momentum, in particular with machine learning (ML) and deep learning (DL) (Bajorath, 2021; Bender and Cortés-Ciriano, 2021). In parallel to the continued contribution of CADD, several methodologies used in CADD have entered the hype cycle with waives of hope, inflated expectations, disappointments, and productive applications. The disillusionments are frequently driven by fashion, exacerbated misuse, and a lack of proper training to interpret the results (MedinaFranco et al., 2021). Examples are quantitative structure-activity relationship studies (QSAR). A few decades ago, there was a hype for QSAR studies; but uneducated use, bad practices, and poor reporting led to inflated expectations and disappointment (Johnson, 2008). As part of the hype, scientific journals containing the word “QSAR” in the title emerged, and years later, some journals were re-named. Molecular docking is another example of a method that is often misused, leading to false expectations and disappointments, not because the technique is not useful but because it is tried to be used for purposes that was not initially designed (e.g., correlation of docking cores with experimental binding affinities). At the time of writing this manuscript, there is a hype for AI, ML, DL; quoting Bajorath, an “AI ecstasy” (Bajorath, 2021). Despite the contributions of CADD in different stages of the drug discovery pipelines and technological advances, there are challenges that need to be addressed. Table 1 outlines the grand challenges that face drug discovery using in silicomethods and AI and are further commented on in this manuscript. The list of topics is not exhaustive; the selected challenges are based on the author’s opinion, and it is intended to be a reference for a continued update. Here, the challenges are organized into six sections. The first two are related to the chemical and biological relevant chemical spaces, respectively; that is, what spaces are being explored? Another section covers methodological challenges: how is being conducted the search for new and better drugs at the intersection of the relevant chemical and biological spaces? The next three sections present hurdles associated with communication and Human interaction in research teams, scientific dissemination, data sharing, and education, respectively. The last section contains the Conclusions.","PeriodicalId":73080,"journal":{"name":"Frontiers in drug discovery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46491690","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}

Villoutreix","doi":"10.3389/fddsv.2021.728469","DOIUrl":"https://doi.org/10.3389/fddsv.2021.728469","url":null,"abstract":"The history of drug discovery and medicine is as ancient as humanity with, according to numerous historians, the first evaluation of the medicinal values of some herbs as early as a few thousand years B.C. in China and in India. Indeed, the practice of Ayurveda, traditional Chinese medicines and the evidence of medicinal practice in Egypt have been documented thousands of years ago. Then in Greece, Hippocrates started to transform medicine from art to science. Intellectual contributions of many great minds from different countries developed over two thousand years gradually established the foundation of scientific medicine. Modern drug discovery started to emerge by the end of the 20th century. Today, this immense field of investigation is characterized by highly complex, time consuming, expensive (yet profitable), often unsuccessful, multidisciplinary processes carried out by a myriad of local, national and international public and private organizations. These players may have divergent interests, and are sometimes driven by concerns other than patients’ health. Given the complexity of drug discovery and development as a field, any attempt to improve the odds of success requires humility, consideration of opposing views and escaping intellectual silos. Although history cannot always foretell the future, there are certainly some lessons to be learned from the past. Strong statements about exploring only some specific scientific areas, with most of the time substantial budget cuts to other disciplines or other departments, should be avoided. For instance, in 1999, it was suggested that the Human Genome Project would transform drug discovery by 2010 and that by 2020 significant improvements in patient care through tailored therapies (personalized medicine) would take place. While the human genome project might change everything in the future, translation to new drugs has been limited (Joyner and Paneth, 2019). The problem is obviously not the human project in itself but the fact that it was oversold, expectations were not realistic and the complexity of the human body in the health and disease states largely underestimated. Along the same line of reasoning but about technologies, J. Bezdek proposed in 1993 a curve showing how technologies tend to progress with time and in silico drug design strategies were analyzed with this approach (Van Drie, 2007). The “Bezdek phases” usually involve an overreaction to immature technology, a peak of hype, followed by despair because the results do not match the expectations. Eventually, after years of efforts, true user benefits are noticed. As today artificial intelligence is increasingly over-advertised in drug discovery and development, the Bezdek theory may apply, suggesting that a curious enthusiastic but cautious approach is advisable (Schneider et al., 2020). Related to this is the need of high quality data that are often missing or maintained confidential in health-related research (Scannell and Bosley, ","PeriodicalId":73080,"journal":{"name":"Frontiers in drug discovery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44528599","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}
