Simply Predict provides in silico predictions for chemical structures

AI-powered in silico toxicology

Artificial intelligence tool to develop in silico models to predict toxicity of chemicals

AI

Applying Artificial Intelligence-based (Machine Learning) approaches, notably Quantitative Structure Activity Relationships (QSARs) & Read-across through a wide range of recognised tools, Simply Predict aims to promote in silico New Approach Methodologies (NAMs) to replace animal testing and provide cost and time-effective solutions to meet R&D needs and regulatory obligations of our clients, notably for REACH, Cosmetics, Pharmaceuticals, Medical Devices, Plant Protection, Biocides and

Endocrine Disruption.

Unlock the benefits of in silico models

in silico QSAR models saves time
in silico QSAR models saves money
in silico QSAR models reduces animal testing
in silico QSAR models are alternative to animal testing
in silico QSAR models are acceptable to regulatory authorities

Significantly saves you time,

costs and resources for all your

R&D requirements and

regulatory submissions.

Growing use in the context of

New Approach Methodologies (NAMs),

Next Generation Risk Assessment (NGRA) and 3Rs (Replacement, Reduction and Refinement of animal testing)

Accepted by regulatory authorities, notably for REACH & Cosmetics

dossier submissions and ICH M7

guideline for Pharmaceuticals

QSAR & Read-across predictions

Simply Predict applies a battery of recognized QSARs and Read-across tools to predict a wide range of Physicochemical, Human Health, Environmental and Ecotoxicological properties. If you intend to use predicted results to fulfill regulatory obligations, our regulatory experts can help with required documentation.

Physicochemical properties predicted using in silico QSAR models

Physicochemical properties

  • Density

  • Dissociation constant (pKa)

  • Flash point

  • Hydrolysis

  • Melting point

  • Boiling point

  • Octanol-water partition coefficient (Log Kow)

  • Vapour pressure

  • Viscosity

  • Water solubility

Toxicology properties predicted using in silico QSAR models

Human Health properties

  • Acute dermal toxicity

  • Acute oral toxicity

  • Acute inhalation toxicity

  • Carcinogenicity

  • Dermal absorption

  • Developmental toxicity

  • Endocrine Disruption (EATS)

  • Eye irritation/corrosion

  • Genotoxicity

  • Mutagenicity

  • Repeated dose toxicity

  • Reproductive toxicity

  • Skin irritation/corrosion

  • Skin sensitisation

Aquatic toxicity to fish predicted using in silico QSAR models

Ecotoxicological properties

  • Acute toxicity to Fish

  • Long-term toxicity to Fish

  • Short-term toxicity to Daphnia

  • Long-term toxicity to Daphnia

  • Short-term toxicity to Algae

  • Endocrine Disruption (EATS)

Environmental toxicity endpoints predicted using in silico QSAR models

Environmental properties

  • Bioaccumulation (BAF)
