In general, discovery scientists working in pharma and biotech are advantaged over their academic counterparts and the relative advantages and disadvantages associated are discussed in depth. Against all odds, an increasing number of important drugs have had their origins in academia. This article reports three case studies from the Liotta Research Group (LRG), which explores the special circumstances that allowed these drug development campaigns to be successful. The first involves the antiretroviral agent, emtricitabine. In this case efficient synthetic methodology, developed in the LRG, coupled with some key university and commercial sector partnerships, enabled a group of academic collaborators to discover and develop a highly effective HIV reverse transcriptase inhibitor. The second case study involves the discovery and development of the breakthrough hepatitis C drug, sofosbuvir. Based on key input from Professors Schinazi and Liotta at Emory University, scientists at the Emory startup, Pharmasset, identified the nucleoside core of the drug that would become sofosbuvir. Subsequent analysis of its phosphorylation profile by Pharmasset scientists suggested that converting it to its corresponding monophosphate prodrug would circumvent a kinase block and enable it to be an effective hepatitis C polymerase inhibitor. The third case study describes the formation of DRIVE (Drug Innovation Ventures at Emory)/EIDD (Emory Institute for Drug Development), which were created to circumvent unintended impediments for carrying out academic drug discovery and development. Although DRIVE/EIDD is a wholly-owned, not-for-profit subsidiary of Emory University, it contains many attributes that enables it to operate much more nimbly than a typical academic laboratory. With an experienced drug development team and no shareholders to distract them, DRIVE/EIDD was able to focus its attention of the development of drugs to address viral diseases of global concern. In particular, their strategy to identify and develop an antiviral agent active against multiple single-stranded RNA viruses led to molnupiravir, a broadly active, oral drug that received Emergency Use Authorization for the treatment of SARS-CoV-2 infections (i.e., COVID-19).</p>","PeriodicalId":7366,"journal":{"name":"Advances in pharmacology","volume":"100 ","pages":"1-38"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141733283","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}

IBD, featured by recurrent symptoms and significant morbidity, poses a significant threat to global health and has an adverse impact on quality of life. Currently, there is no curative therapy for IBD, and the available medications are only for managing the disease condition, likely owing to the insufficient understanding of the underlying pathophysiology processes involved in IBD, and the lack of safe and effective medicines. Thus, novel targeted therapies for IBD are urgently needed for better efficacy with an improved adverse event profile. As the most extensively studied member of bromodomain and extra terminal domain (BET) family proteins, bromodomain-containing protein 4 (BRD4) is emerging as a promising epigenetic therapeutic target for IBD. Pharmacological inhibition of BRD4 with selective small molecule inhibitors shows potent anti-inflammatory effects in both in vitro and different IBD mouse models. Herein, we summarize current knowledge in understanding the role of BRD4 in the pathogenesis and development of IBD, and the clinical landscape of developing BET/BRD4 inhibitors and emerging BRD4-targeted degraders as promising therapeutical alternatives.

We delve into the multifaceted roles of Dectin-1 in immune response modulation, focusing on its interactions with the gut microbiota and immune system. Key sections include an examination of intestinal dysbiosis and its impact on IBD, highlighting the critical role of fungal dysbiosis and immune responses mediated by Dectin-1. The chapter discusses the dual functions of Dectin-1 in maintaining gut homeostasis and its contribution to disease pathogenesis through interactions with the gut's fungal community. Furthermore, the genetic and molecular mechanisms underpinning Dectin-1's role in IBD susceptibility are explored, alongside its signaling pathways and their effects on immune modulation. We also present therapeutic strategies targeting Dectin-1, including innovative drug delivery systems that leverage its natural binding affinity for β-glucans, enhancing targeted delivery to inflamed tissues. The chapter underscores the potential of dietary modulation of Dectin-1 pathways to restore gut microbiota balance and suggests future research directions to fully exploit Dectin-1's therapeutic potential in managing IBD.

Dysfunctional DAT is associated with aberrant synaptic dopamine transmission and enhanced drug-seeking and taking behavior. Studies in cultured cells and ex vivo suggest that DAT function is sensitive to membrane cholesterol content. Although it is largely unknown whether psychostimulants alter cholesterol metabolism in the brain, emerging evidence indicates that peripheral cholesterol metabolism is altered in patients with psychostimulant use disorder and circulating cholesterol levels are associated with vulnerability to relapse. Cholesterol interacts with sphingolipids forming lipid raft microdomains on the membrane. These cholesterol-rich lipid raft microdomains serve to recruit and assemble other lipids and proteins to initiate signal transduction. There are two spatially and functionally distinct populations of the DAT segregated by cholesterol-rich lipid raft microdomains and cholesterol-scarce non-raft microdomains on the plasma membrane. These two DAT populations are differentially regulated by DAT blockers (e.g. cocaine), substrates (e.g. amphetamine), and protein kinase C providing distinct cholesterol-dependent modulation of dopamine uptake and efflux. In this chapter, we summarize the impact of depletion and addition of membrane cholesterol on DAT conformational changes between the outward-facing and the inward-facing states, lipid raft-associated DAT localization, basal and induced DAT internalization, and DAT function. In particular, we focus on how the interactions of the DAT with cocaine and amphetamine are influenced by membrane cholesterol.

To overcome these limitations, we describe a diverse array of novel therapeutic approaches. In the area of immune homeostasis restoration, the focus is on targeting cytokine networks, leukocyte trafficking, novel immune pathways, and cell therapies involving regulatory T cells and mesenchymal stem cells (MSC). Recognizing the critical role of impaired intestinal barrier integrity in IBD, we highlight therapies aimed at restoring barrier function and promoting mucosal healing, such as those targeting cell proliferation, tight junctions, and lipid mediators. Addressing the challenges posed by fibrosis and fistulas, we describe emerging targets for reversing fibrosis like kinase and cytokine inhibitors and nuclear receptor agonists, as well as the potential of MSC for fistulas. The restoration of a healthy gut microbiome, through strategies like fecal microbiota transplantation, rationally defined bacterial consortia, and targeted antimicrobials, is also highlighted. We also describe innovative approaches to gut-targeted drug delivery to enhance efficacy and minimize side effects.
