About us

ProtoQSAR is a company founded in 2012, with corporate address in Valencia and office located at the Technological Park of Paterna (Valencia).

Our activity consists in the development and application of computational methods for the evaluation of physicochemical, biological and/or (eco)toxicological properties of chemicals, either of natural origin or synthesized. Our computer tools allow us to work in a “virtual” environment, which has advantages over traditional laboratory tests.

ProtoPRED

Try our computational prediction platform for chemical compounds

ProtoPRED uses its own QSAR (Quantitative Structure-Activity Relationships) models,  widely applied in sectors such as cosmetics, pharmaceuticals and chemicals. This tool allows the prediction of a wide spectrum of properties of industrial and regulatory interest, ensuring the obtaining of valid documents in accordance with regulations such as REACH and ICH. With ProtoPRED, companies can efficiently comply with current regulations and optimize their registration processes

Mission

Given the exclusively computerized nature of our methods, ProtoQSAR activity has a very positive social impact. First, through computation it is possible to reduce the number of laboratory animal tests, or even to replace them in some cases*. Approximately 12 million vertebrate animals are slaughtered annually in the EU for scientific or regulatory purposes (Taylor, K., & Rego, L. (2016). EU statistics on animal experiments for 2014. ALTEX, 33, 465-468). These tests are ethically questionable, and their preparation and execution are also expensive and time consuming.

On the other hand, our activities are also intended to contribute to environmental improvement. We have predictive models for a large number of eco-toxicological parameters (aquatic toxicity, toxicity in different species such as bees or terrestrial organisms, etc.), which allows us to guide the development of new active substances towards those that have proven effectiveness while respecting our natural environment.

*Computational approaches are part of the so-called alternative methods, whose purpose is the fulfillment of the “3 Rs”: refinement of conventional methods to reduce the potential suffering of living beings used in experimentation, reduction in the number of animals used, and finally the replacement of said tests by others in which the animal sacrifice is not necessary.

Values

At ProtoQSAR we firmly believe in the value of experience, the culture of hard work and the satisfaction for well-donework. We intend to satisfy our customers/collaborators by contributing our commitment in each of the projects in which we participate, and our high motivation to develop them and bring them to a good end.

We fully adhere to the proposals made at the 1st National Congress of Entrepreneurial Scientists (Valencia, 2012) in which a code of good practices was proposed that would make compatible the responsible use of Science with Entrepreneurship. In ProtoQSAR we subscribe completely and without exception all the points of said code. We are convinced of the importance of the good practices of entrepreneurial scientists, respect for our environment and society as a whole, and we are committed to contributing to a more fair and solidary society.

Our staff is characterized by its high academic profile and extensive scientific background. The technical team of ProtoQSAR is formed by specialists in different areas (pharmacy, chemistry, toxicology and ecotoxicology …) with extensive experience in both academic and industrial sides.

We have more than 100 publications in national and international scientific journals, eight chapters in specialized books and more than 80 participations and presentations in technical congresses.

Below we present the team that is part of ProtoQSAR in Spain. If you would like to meet the ProtoQSAR Italy team, click here.

Frequently asked questions

What services does ProtoQSAR offer?

ProtoQSAR is a company specialized in QSAR models and in silico toxicological predictions for regulatory support (REACH, CLP, ICH, K-REACH, etc.). We offer customized studies (QSAR, SAR, read-across, compound prioritization, etc.) and ProtoPRED®, our molecular prediction platform featuring more than 60 models covering toxicity, physicochemical properties, ecotoxicity, and ADME.

We work with companies in the pharmaceutical, chemical, cosmetic, agrochemical sectors, as well as regulatory consultancies. We also provide practical training courses in QSAR and regulatory frameworks.

Contact ProtoQSAR / Request a ProtoPRED demo

How long does it take to obtain results?

With ProtoPRED®, predictions are generated instantly. For tailor-made studies, timelines depend on the number of compounds and the scope of the study and typically range from a few weeks up to approximately two months. Upon completion, we deliver reports ready for submission to regulatory authorities (QPRF).

Tell us about your project.

What software does ProtoQSAR use to develop its models?

We use proprietary QSAR models integrated into ProtoPRED, our molecular prediction platform with more than 60 models for toxicity, physicochemical properties, ecotoxicity, and ADME.

For customized studies, we may also use third-party tools such as QSAR Toolbox and VEGA when no equivalent internal model is available in ProtoPRED, ensuring regulatory acceptability.

View list of models.

Are ProtoQSAR QSAR models accepted under REACH, CLP, ICH, or other regulations?

Yes. Our models follow OECD principles and are documented with QMRF and QPRF for each prediction, facilitating regulatory acceptance and reducing the need for experimental testing.

In addition, we have examples of regulatory acceptance of our models by different authorities.

Does ProtoQSAR participate in collaborative projects?

Yes. We collaborate in European consortia (HORIZON, IHI, etc.), national programs (Torres Quevedo, NANOTECH), and regional calls (IVACE, AVI, etc.).

At ProtoQSAR, together with Moldrug and ProtoQSAR Italy (our associated companies), we are actively seeking industrial and academic partners.

Do you have a proposal? Contact us at bd@protoqsar.com.

How much does a ProtoPRED prediction or a customized study cost?

ProtoPRED® operates on a token-based system with volume discounts: the more tokens you purchase, the lower the cost per prediction. We also offer annual licenses for teams that use the platform intensively; the license becomes cost-effective from approximately 200 predictions per year.

For customized studies, pricing depends on the number of compounds, the endpoints involved, and the level of regulatory documentation required.


Request ProtoPRED pricing options / Request a quote for a customized study

Do you provide scientific support and regulatory guidance?

Yes. In addition to generating QSAR models and predictions, we provide scientific and regulatory support, including in silico strategy design, validation and interpretation of results, and preparation/review of QMRF and QPRF so that predictions comply with OECD guidelines and/or applicable legal frameworks, meeting regulatory authority requirements.

Our regulatory team will be pleased to assist you. Contact us at regulatory@protoqsar.com.

How are confidentiality and data protection managed?

In ProtoPRED®, privacy and data protection are built into your account. From the user page (Reports data), you can activate Data Privacy to irreversibly delete all prediction results, retaining only the model used and the date.

We also offer the possibility of signing an NDA (Non-Disclosure Agreement) to ensure information security, privacy compliance, and data protection.
