To enable toxicological predictions, QST models require incorporation of mechanistic details specific to safety applications including the ability to accurately model supratherapeutic doses and appropriately represent safety endpoints. Unique to the field of toxicology, mechanistic knowledge is often described through the use of adverse outcome pathways (AOPs), which formally represent existing knowledge about mechanisms of toxicity. The toxicities represented by QST models can arise from exaggerated or adverse pharmacological effects of engaging the drug's intended target (on-target toxicity) or from adverse events due to modulation of additional targets beyond the primary target (off-target toxicity). In cases of on-target toxicity, QST models can be considered as a type of Quantitative Systems Pharmacology (QSP) model that incorporates safety biomarkers and often includes simulations performed outside the therapeutic dose range to explore potential adverse consequences of exaggerated pharmacology in a pre-clinical or clinical setting. QST models assessing off-target toxicities can be considered distinct from QSP models in that they are typically applicable across molecules of a given modality which can (and often do) have different primary therapeutic targets. Off-target QST models commonly focus on the interrogation of general (e.g. pan-compound) toxicity mechanisms, often within a specific organ system. It can be difficult to categorize a model as purely QSP or QST (given that some models can be considered as both a QSP and a QST model), and therefore, we encourage readers to refer to a model based on its context of use and application. Thus, throughout this chapter, we refer to models as QST models when the context of use is to understand safety-related questions. To illustrate QST modeling approaches, examples of QST model applications for on-target and off-target toxicities at different stages of the drug discovery and development pipeline are presented and discussed. Additionally, contexts of use, triggers, key objectives, and potential impacts of QST models including the types of decisions QST applications can inform across drug discovery and development are reviewed. The chapter concludes with an overview of key challenges and future perspectives in the field of QST.</p>","PeriodicalId":12859,"journal":{"name":"Handbook of experimental pharmacology","volume":" ","pages":"285-306"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144834935","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}

This chapter provides a high-level overview of fundamental factors that determine the disposition and physiological responses to drugs and the application of compartmental models to characterize the time-course of drug exposure and pharmacological effects. Many of these processes are subject to capacity-limitation, which is defined by a nonlinear function containing a driving substrate concentration and parameters representing the capacity of the process and a substrate affinity constant. Most contemporary mechanism-based pharmacodynamic models are developed by integrating an appropriate drug exposure forcing function, a mathematical model of the interaction between the drug and its target (i.e., binding and transduction), and the physiological turnover (or production and loss) of the biomarker of drug response. Numerous complexities can be introduced to basic models, such as homeostatic feedback, tolerance mechanisms, disease progression, drug interactions, circadian rhythms, and many others.

Many major active components from various natural products have been extracted, isolated, and evaluated for their pharmacological efficacy and safety.

Pluripotent stem cells can differentiate into all of the cell types constituting the adult body. Our current understanding is that pluripotent stem cells transition through three stages: a naïve state, a formative state, and a primed state. The stemness and differentiation of pluripotent stem cells depend on cell-surface glycans, which work as essential modulators in ligand-receptor interactions, cell-cell interactions, and cell-extracellular matrix interactions. Cell-surface glycans bind to various signal ligands, including Wnt, fibroblast growth factors, and bone morphogenetic proteins, and are tissue-specific and developmentally regulated. In addition, intracellular O-linked N-acetylglucosamine, a modification found on only nuclear or cytoplasmic proteins, regulates core transcription factors involved in stemness, phosphorylation of downstream signal components, epigenetics, and liquid-liquid phase separation. Thus, various kinds of glycans regulate each stem cell status; furthermore, different glycan structures at each stage are simultaneously epigenetically regulated by the polycomb repressive complex PRC2.
