24 endpoints · 34 models · All ICH/OECD aligned
Mutagenicity (bacterial reverse mutation / Ames test)
ICH S2(R1)Predicts mutagenic potential via bacterial reverse mutation assay in Salmonella typhimurium and E. coli strains. A core regulatory genotoxicity test required in early non-clinical safety studies.
Genotoxicity: in vitro micronucleus assay
ICH S2(R1)Detects micronuclei in the cytoplasm of cells — fragments produced by DNA breakage (clastogens) or whole chromosomes displaced by disruption of the mitotic apparatus (aneugens).
Genotoxicity: in vivo micronucleus assay (mouse)
ICH S2(R1)Predicts clastogenic and aneugenic effects in mouse bone marrow and/or blood erythrocytes — the in vivo complement to the in vitro assay.
Chromosomal aberration (in vitro)
ICH S2(R1)Predicts structural chromosomal aberrations in mammalian cells — breaks, gaps, and rearrangements observed in metaphase cells. A standard component of the ICH core genotoxicity battery.
DNA damage / stress response (p53)
GenotoxicityPredicts activation of the tumor suppressor p53, a key stress-responsive indicator of DNA damage and potential genotoxicity. Widely used in regulatory screening and mechanistic hazard assessment.
DNA damage response (ATAD5)
GenotoxicityPredicts stabilisation of ATAD5, which accumulates in response to DNA damage and replication stress. Provides a p53-independent readout of genotoxic potential, covering compounds that evade p53-based detection.
Carcinogenicity (mouse, rat)
ICH S1A/BRodent carcinogenicity prediction based on two-year bioassay data. Separate models for rat and mouse, both sexes, plus a general cross-species model.
Cardiotoxicity (hERG, CaV1.2, NaV1.5)
ICH S7BThree models covering the major cardiac ion channels. NaV1.5 governs rapid depolarization, CaV1.2 contributes to the plateau phase, and hERG mediates repolarization. Inhibition may lead to QT prolongation and proarrhythmic effects.
Hepatotoxicity (DILI)
FDA DILIDrug-Induced Liver Injury prediction based on human hepatotoxicity data annotated from FDA drug labels, covering serum enzyme elevations, jaundice, and hepatic failure.
Neurotoxicity: acetylcholinesterase (AChE) inhibition
NeurotoxicityPredicts inhibition of AChE, leading to acetylcholine accumulation and disruption of normal neurotransmission — relevant for pesticide and drug candidates.
Drug-Induced Neurotoxicity (DINeurot)
NeurotoxicityPredicts nervous system damage or dysfunction caused by drugs or chemicals. Neurotoxicity is a leading cause of post-market drug withdrawals; training data covers clinical cases of neurotoxic effects.
Drug-Induced Nephrotoxicity (DIN)
SafetyPredicts renal damage potential. Nephrotoxicity contributes to 2% of drug failures in pre-clinical studies and 19% in phase 3 — early in silico flagging saves significant time and cost.
Acute oral toxicity (GHS classification)
GHS / OECD 423Predicts the GHS acute toxicity category after single oral administration in rodents, supporting hazard classification and labelling under CLP and OECD TG 423.
Developmental toxicity potential
ICH S5(R3)Predicts the potential to interfere with embryo-fetal development — teratogenicity, growth retardation, and functional deficits. Supports early prioritisation ahead of costly ICH S5(R3) reproductive toxicity studies.
HepG2 cytotoxicity
CytotoxicityPredicts cytotoxic effects in human hepatocellular carcinoma cells. Cytotoxicity may underlie organ toxicity, genotoxicity artefacts, or carcinogenic responses — a key in vitro safety model.
Oxidative stress response (Nrf2/ARE)
MechanismPredicts activation of the Nrf2/antioxidant response element pathway — the primary cellular defence against electrophiles and reactive oxygen species, and an early mechanistic indicator of oxidative-stress-mediated toxicity.
Mitochondrial toxicity (membrane potential)
MechanismPredicts disruption of the mitochondrial membrane potential, an early marker of mitochondrial dysfunction implicated in drug-induced liver injury, myopathy, and cardiotoxicity.
Aryl hydrocarbon receptor (AhR) activation
MechanismPredicts activation of AhR, a ligand-activated transcription factor that triggers CYP enzyme induction and downstream toxicity pathways including immunotoxicity, developmental toxicity, and cancer. Widely used in regulatory and mechanistic hazard screening.
Endocrine — receptor binding (ER, ER-LBD, AR, AR-LBD, aromatase)
EndocrineFive models covering full-length estrogen and androgen receptor activity, the corresponding ligand-binding-domain assays that isolate direct receptor binding, and aromatase inhibition, which governs androgen-to-estrogen conversion. Core battery for endocrine disruption screening under REACH and EPA EDSP.
Endocrine — hormone synthesis and metabolism (TPO, PPARγ)
EndocrineThyroid peroxidase inhibition blocks thyroid hormone synthesis, affecting neurodevelopment, metabolism, and cardiac activity. PPARγ activation drives adipogenesis and metabolic disruption. Both are high-priority endocrine endpoints.
Eye irritation and corrosion
OECD 405Predicts ocular irritation and corrosion potential against GHS categories, supporting animal-free classification for pharmaceuticals, cosmetics, agrochemicals, and industrial chemicals.
Skin sensitization
OECD 429Predicts the potential to cause allergic contact dermatitis. Of high regulatory relevance for pharmaceuticals, cosmetics, and industrial chemicals; aligned with OECD TG 429 and the adverse outcome pathway for skin sensitization.
Cell cycle
GenotoxicityPredicts compound interference with G0/G1, S, G2, and M cell-cycle phases. Alterations are closely linked to genotoxicity, carcinogenicity, and cytotoxicity and are of high relevance for safety assessment.
Immunotoxicity (RPMI-8226, MOLT-4, IL-1B)
ImmunotoxicityThree models covering compound-induced effects on human hematopoietic cell lines (RPMI-8226, MOLT-4) and the pro-inflammatory cytokine IL-1B — relevant for immunosuppressive, immunostimulatory, or pro-inflammatory hazard assessment.
ADME & Pharmacokinetics
11 endpoints · 21 models
Absorption
Aqueous solubility (logS)
Predicted at 25°C in mol/L (log scale). Poor aqueous solubility is a major cause of low bioavailability and formulation failure in drug development.
Caco-2 permeability
Predicts apparent permeability across Caco-2 monolayer — the standard in vitro reference for oral absorption and intestinal permeability screening.
Human Intestinal Absorption (HIA)
Predicts the fraction of orally administered compound absorbed from the gastrointestinal tract into the bloodstream.
PAMPA permeability
Parallel Artificial Membrane Permeability Assay: predicts passive transcellular diffusion independent of transporters and metabolism — a fast early filter for absorption potential, complementary to Caco-2.
Distribution
Human Plasma Protein Binding (PPB)
Predicts reversible drug binding to plasma proteins (albumin, alpha-1 acid glycoprotein). Only the unbound fraction is pharmacologically active.
Blood-Brain Barrier (BBB) permeability
Predicts logBB (concentration ratio brain/blood). Neuroactive drugs must cross BBB; peripherally-acting drugs should not, to avoid psychotropic side effects.
Metabolism
CYP450 substrates (CYP1A2, 2C9, 2C19, 2D6, 3A4)
Five models predicting whether the compound is a substrate of the major CYP450 enzymes — informing metabolic liability and potential for drug-drug interactions.
CYP450 inhibition (CYP1A2, 2C9, 2C19, 2D6, 3A4)
Five models predicting inhibitory potential against the CYP450 isoforms responsible for ~90% of drug metabolism. Critical for drug-drug interaction assessment.
Metabolic stability / intrinsic clearance (CLint)
Predicts intrinsic hepatic clearance from microsomal stability data — key input for pharmacokinetic modelling and dose prediction.
Excretion
Efflux transporters (P-glycoprotein, BCRP)
TransporterTwo models covering P-glycoprotein (ABCB1) and BCRP (ABCG2) — the efflux pumps that most strongly limit oral bioavailability and CNS exposure. Assessment of both is expected under FDA and EMA drug–drug interaction guidance.
OATP inhibition (OATP1B1, OATP1B3)
TransporterPredicts inhibition of hepatic uptake transporters OATP1B1 and OATP1B3 — key determinants of hepatic drug disposition and a major factor in transporter-mediated drug–drug interactions. Widely used in regulatory safety assessment.
