ProtoQSAR is a company founded in 2012, with corporate address in Valencia and offices located in the European Center of Innovative Enterprises (CEEI) 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.

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.

Frequently asked questions

Is ProtoQSAR a consultancy company or a vendor of specialized software on molecular modeling and chemoinformatics?

ProtoQSAR is a company that conducts studies for its clients and collaborators, currently we do not sell molecular simulation programs, nor our QSAR models. We provide our services to groups and entities that for the most part do not have specific training in chemistry-computing and molecular modeling -or it is very limited- and therefore our expertise can represent a greater added value for them.

How long does it take for a client to get the results of their project?

The projects in which we work are very different from each other, and prior to their execution we make an evaluation of the time necessary. The great advantage of computer studies compared to experimental tests is that we can obtain results in a much shorter time. For example, the prediction of the profile of a compound by QSAR methods is very fast (few days), since we already have models for this kind of evaluation. The virtual screening of a database to search for a candidate interacting with a particular target can represent 1 week to 2 months, depending on the number of chemicals filtered (a few thousands or hundreds of thousands).

Can I propose a collaborative project to ProtoQSAR? How?

At ProtoQSAR we are very interested in the development of new collaborative projects in which chemoinformatics and molecular modeling can provide an added value to our collaborators. If you have any idea to raise, please contact us explaining your proposal, and in a very short time we will give you an answer.

How much do ProtoQSAR services cost? How are the costs estimated?

Costs vary depending on the type of service we provide and the time we spend on a project. Since computing allows results to be obtained in a much shorter time than experimental tests, our services are also much cheaper.

What software does ProtoQSAR use to develop its models?

In ProtoQSAR we work with the whole palette of molecular modeling and chemoinformatics techniques, and therefore we have all the necessary programs for the execution of our projects. We systematically use standardized programs that are well referenced in the scientific literature, and sometimes we carry out our own software developments for specific needs. In any case, these developments remain the property of ProtoQSAR, and are not for sale.

What degree of confidence do the computer models have?

Computational studies are not an “exact science” and a certain degree of uncertainty is expected, as is the case with experimental tests (both in vitro and in vivo) to a certain extent. We conduct our studies according to scientifically recognized quality guidelines, and our extensive experience (demonstrable through our scientific and technical publications) makes our studies as accurate as possible. Before conducting a study, we inform our clients about the reasonable results’ expectations. At the time of providing the results, we also contribute our expert evaluation and inform the customer of the potential limitations of the obtained models.

How much time is needed to do a virtual screening? And how many compounds can be filtered?

Both questions are linked: the execution time of a virtual screening depends essentially on the number of compounds that are screened. To give a general idea, an already developed QSAR model allows the user to evaluate tens of thousands of compounds in a single day. Screening by docking (in a therapeutic target with known 3D structure) requires a longer period of time, but we can also evaluate thousands of compounds in a few days.

Can computational models be applied at the regulatory level?

Chemoinformatic models are recognized as a valid alternative at a the regulatory level, and the international regulations themselves increasingly encourage their use. For example, in the case of REACH, ECHA systematically requests companies to demonstrate that they have fully considered the use of alternative methods before concluding that a new test with vertebrates is necessary.

Can computer models replace the experimental tests required by legislation (e.g. REACH)?

Yes, in a lot of cases our models make it unnecessary to perform additional assays. This is particularly common when there is already some bibliographic information on the studied compounds, or when the products are of natural origin. In other cases the computational studies do not completely replace the experimental tests, but it is usually possible to reduce them (and therefore reduce time and costs). Another factor to consider is the credibility of the company in front of the authorities, which is clearly favored when presenting a complete dossier including the evaluation by alternative methods.

What type of model do I need for the registration/authorization of my substance: QSAR or read-across?

The type of model depends on the baseline information and on the substance to be evaluated. In principle, QSAR models are technically more robust and reliable, but they cannot always be used (for example, if the compound to be evaluated does not fall within the domain of applicability of the compounds that have been used to generate the models). In that case read-across is a good alternative, since this technique has the same validity at the regulatory level when properly executed by an experienced professional.

What is the “Applicability Domain”? How does it affect the prediction of my substance at the regulatory level?

Applicability domain is the “chemical space” to which a specific compound belongs in relation to the compounds that have served as the basis for developing a QSAR model. One of the parameters required by the OECD (and therefore necessary from a regulatory point of view) when determining whether a QSAR is valid on a given compound is the characterization of that space.

How are QSAR models validated?

All our models are subjected to a double validation, internal and external, and when possible we perform an experimental validation with independent structures belonging to the same chemical space or “domain of applicability”.
