The partnership brings more than 60 ProtoPRED® predictive models to the 150+ computational tools in ToxIndex, supporting faster, more transparent and efficient in silico assessments.

ROCKVILLE, Md. and VALENCIA, Spain, Oct. 22, 2026 /PRNewswire/ -- Insilica, Inc., developer of the ToxIndex chemical safety intelligence platform, and ProtoQSAR SL, a computational chemistry company specializing in predictive toxicology, today announced a technology integration and distribution agreement.
The integration uses a containerized deployment of ProtoPRED®, enabling its predictive models to operate within the ToxIndex environment. For on-premises deployments, this approach is designed to support the protection of confidential chemical structures within customer-controlled infrastructure.

As regulatory authorities worldwide accelerate the adoption of New Approach Methodologies (NAMs), safety teams need fast, reliable, animal-free tools to evaluate chemical hazards.

The suite delivers more than 60 predictive models across nine specialized ProtoPRED® modules built for major regulatory requirements:

ProtoICH: Pharmaceutical impurity testing (ICH M7)
ProtoREACH: International regulatory assessments (e.g., EU REACH and K-REACH)
ProtoADME: Drug absorption and metabolism profiling
ProtoPHYSCHEM: Chemical and physical property profiling
ProtoTOX: Organ and systemic toxicity predictions
ProtoECO: Ecotoxicity and environmental fate predictions
ProtoED: Endocrine disruption predictions
ProtoNANO: Nanomaterial safety modeling
GenoITS: Integrated genotoxicity assessment

"By embedding ProtoPRED® directly into ToxIndex, we let safety teams evaluate candidate chemicals in minutes, and on-premises customers keep proprietary structures behind their own firewall," said Tom Luechtefeld, PhD, Chief Executive Officer of Insilica, Inc.

"Partnering with Insilica expands our regulatory-proven models directly into an integrated AI workflow, giving teams the speed and confidence they need for critical filings," said Rafael Gozalbes, PhD, Chief Executive Officer of ProtoQSAR SL.

ProtoPRED® is available now to ToxIndex enterprise customers through an annual company-wide license with unlimited predictions and no per-user or per-query fees.
