Toxicity

22 endpoints ยท All ICH/OECD aligned

Mutagenicity (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 test

ICH S2(R1)

Detects micronuclei in the cytoplasm of cells โ€” fragments produced by DNA breakage (clastogens) or whole chromosomes displaced by disruption of the mitotic apparatus (aneugens).

Genotoxicity: in vivo micronucleus test (mouse)

ICH S2(R1)

Predicts clastogenic and aneugenic effects in mouse bone marrow and/or blood erythrocytes โ€” the in vivo complement to the in vitro assay.

Genotoxicity: in vitro chromosomal aberration test

ICH S2(R1)

Predicts structural chromosomal aberrations in mammalian cells โ€” breaks, gaps, and rearrangements observed in metaphase cells. A standard component of the ICH core genotoxicity battery.

Carcinogenicity

ICH S1A/B

Rodent carcinogenicity prediction based on two-year bioassay data. Separate models for rat/mouse, both sexes, plus a general cross-species model.

CaV1.2, NaV1.5 and hERG Cardiotoxicity

ICH S7B

Predicts inhibition of three 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 DILI

Drug-Induced Liver Injury prediction based on human hepatotoxicity data annotated from FDA drug labels, covering serum enzyme elevations, jaundice, and hepatic failure.

Drug-Induced Nephrotoxicity (DIN)

Safety

Predicts renal damage potential. Nephrotoxicity contributes to 2% of drug failures in pre-clinical studies and 19% in phase 3 โ€” early in silico flagging saves significant time and cost.

Acetylcholinesterase (AChE) inhibition

Neurotoxicity

Predicts inhibition of AChE, leading to acetylcholine accumulation and disruption of normal neurotransmission โ€” relevant for pesticide and drug candidates.

Drug-Induced Neurotoxicity (DINeurot)

Neurotoxicity

Predicts 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.

Estrogen Receptor Binding

Endocrine

Predicts binding to estrogen receptors โ€” key for endocrine disruption assessment. Disruption can lead to reproductive issues, cancer, and cognitive impairments; required under REACH and EPA regulations.

Androgen Receptor Binding

Endocrine

Predicts androgen receptor activity. AR disruption by exogenous compounds can cause reproductive disorders and various cancers โ€” essential for endocrine disruptor screening in regulatory submissions.

Thyroid Peroxidase (TPO) Inhibition

Endocrine

Predicts inhibition of TPO, a crucial enzyme in thyroid hormone synthesis. THs regulate neurodevelopment, metabolism, and cardiac activity; TPO inhibition is a high-priority safety endpoint.

Acute Oral Toxicity (AOT)

GHS / OECD 423

Predicts LD50 after single oral administration in rodents. Compounds are classified per CPSC and DoD guidelines based on toxic reactions within 24โ€“48 hours post-exposure.

Skin Sensitization

OECD 429

Predicts 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.

HepG2 Cytotoxicity

Cytotoxicity

Predicts cytotoxic effects in human hepatocellular carcinoma cells. Cytotoxicity may underlie organ toxicity, genotoxicity artefacts, or carcinogenic responses โ€” a key in vitro safety model.

Cell Cycle

Genotoxicity

Predicts 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.

Aryl Hydrocarbon Receptor (AhR)

Mechanism

Predicts 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.

Respiratory Toxicity

Safety

Predicts adverse effects in the respiratory tract โ€” airway irritation, bronchoconstriction, impaired gas exchange, or structural lung damage. Relevant for occupational, environmental, and pharmaceutical safety assessment.

Stress Response p53 (SR-p53)

Genotoxicity

Predicts 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.

RPMI-8226, MOLT-4 and IL-1B Immunotoxicity

Immunotoxicity

Predicts compound-induced effects on human hematopoietic cell lines (RPMI-8226, MOLT-4) and the pro-inflammatory cytokine IL-1B โ€” relevant for immunosuppressive, immunostimulatory, or pro-inflammatory hazard assessment.

Organic Anion Transporting Polypeptide 1B1 and 1B3 (OATP1B1/1B3)

Transporter

Predicts inhibition of hepatic uptake transporters OATP1B1 and OATP1B3 โ€” key determinants of hepatic drug disposition and a major factor in transporter-mediated drugโ€“drug interactions. Widely used in regulatory safety assessment.

ADME & Pharmacokinetics

7 endpoints

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.

Human Plasma Protein Binding (PPB)

Predicts reversible drug binding to plasma proteins (albumin, alpha-1 acid glycoprotein). Only the unbound fraction is pharmacologically active.

Caco-2 Permeability

Predicts apparent permeability across Caco-2 monolayer โ€” 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.

CYP450 Inhibition (CYP3A4, 2C9, 2D6, 2C19, 1A2)

Predicts inhibitory potential against the five major CYP450 isoforms responsible for ~90% of drug metabolism. Critical for drug-drug interaction assessment.

CYP450 Substrates (CYP3A4, 2C9, 2D6, 2C19, 1A2)

Predicts whether the compound is a substrate of major CYP450 enzymes โ€” informing metabolic liability and potential for drug-drug interactions.

Metabolic Stability / Intrinsic Clearance (CLint)

Predicts intrinsic hepatic clearance from microsomal stability data โ€” key input for pharmacokinetic modelling and dose prediction.

Physicochemical Properties

Aqueous Solubility (logS)

Predicted at 25ยฐC in mol/L (log scale). Poor aqueous solubility is a major cause of low bioavailability and formulation failure in drug development.
