Pharmacology and toxicology explore how substances interact with living systems, ranging from the development of life-saving medicines to understanding the dangers of chemical exposure. This field sits at the critical intersection of chemistry and biology, asking essential questions about how drugs work, how the body processes them, and what happens when things go wrong. It is a dynamic area where researchers constantly strive to improve patient safety while discovering new therapeutic possibilities.

At Gist.Science, we bridge the gap between complex research and public understanding by curating the latest preprints from bioRxiv in this vital category. Our team processes every new submission from bioRxiv as it appears, transforming dense scientific data into both plain-language overviews and detailed technical summaries. This ensures that whether you are a specialist or a curious reader, you can grasp the significance of these emerging findings without getting lost in jargon.

Segmented regression to streamline semi-mechanistic pharmacodynamic modelling of antibiotic effects

This paper proposes a three-step workflow utilizing segmented regression on time-kill assay data to efficiently derive concentration-effect relationships and streamline the development of robust semi-mechanistic pharmacodynamic models for antibiotics, as demonstrated with colistin against *Pseudomonas aeruginosa*.

Hazard Structure and Repair Kinetics: A 2x2 Classification that Resolves the Stochastic-Death / Individual-Tolerance Dilemma

This paper resolves the stochastic-death versus individual-tolerance dilemma in GUTS modeling by proposing a 2x2 classification of hazard structures and repair kinetics, demonstrating through empirical evidence that a peak-based hazard model with saturating repair is the superior default for predicting survival under time-variable exposure.

A Physics-Constrained Marcus-Theory Optimization Framework Restores Parameter Identifiability in Deep-Pocket Oncogenic Drug Kinetics: A KRAS G12C and STAT3 Case Study

This paper introduces a physics-constrained "Cluchagues-Marcus Framework" that incorporates local dielectric effects to restore parameter identifiability in deep-pocket oncogenic drug kinetics, demonstrating through synthetic and real-world data that anchoring the dissociation constant (KdK_d) resolves non-identifiability while predicting significant rate acceleration upon water exclusion in KRAS G12C and STAT3 targets.

Discovery of P1-P2 depeptidized boronic acid based Plasmodium falciparum SUB1 inhibitor

This study reports the rational design and synthesis of non-peptidic, depeptidized boronic acid inhibitors targeting *Plasmodium falciparum* SUB1, which achieved low-nanomolar enzymatic potency through specific structural modifications but require further optimization to improve cellular permeability and blood-stage antimalarial activity.

Long-PDE4D degradation attenuates left ventricular cardiomyocyte hypertrophic remodelling

This study demonstrates that targeted degradation of long PDE4D isoforms using the proteolysis-targeting chimera KTX-184 attenuates pathological cardiac hypertrophy by enhancing compartmentalised cAMP signalling while preserving contractile function in both rat and human cardiomyocytes.

Mammalian cell-derived fatty acid biosynthesis derailment products are pro-inflammatory signalling molecules at the orphan receptor GPR84

This study identifies Cn-alkylpyrones, which are produced by mammalian cells when fatty acid synthase ketoreductase domains are inhibited, as potent endogenous agonists that activate the orphan receptor GPR84 to drive pro-inflammatory signaling.

Modulation of planarian seizure-like activity via antiseizure medications

This study demonstrates that while planarians can serve as a high-throughput model for screening antiseizure medications against organophosphate-induced neurotoxicity, the efficacy of these drugs varies significantly depending on the specific proconvulsant agent and planarian species, highlighting the need to further define the underlying molecular mechanisms.

A corticopapillary Gdf15 response links maladaptive collecting duct remodeling to polyuria during lithium exposure

This study identifies renal Gdf15 induction as a critical mechanistic link between lithium-induced collecting duct stress and the concurrent development of polyuria and microcystic remodeling, demonstrating that Gdf15 deletion in mice attenuates both functional water conservation defects and structural kidney injury.
