We identify target and off-target proteins
of any small molecule on a proteome-wide scale
HIGH EFFICIENCY

Our technologies allow to identify target and off-target proteins of any drug through a systematic analysis and ranking of very large protein databases, such as the whole available human structural proteome.

INNOVATION
&
UNIQUENESS

Our tools have unique potentialities in identifying drug binding sites on protein 3D-structures whether or not they are occupied, strongly distorted, or even completely closed, compared to a suitable conformation for the binding.

EXPERIMENTAL VALIDATIONS

To validate our approach while ensuring maximum objectivity and reliability, we have used our technology to tackle scientific problems still waiting to be solved. The results achieved have been experimentally confirmed by academic research centres and published in peer-reviewed scientific journals.

Clarifying ADVERSE EFFECTS

Adverse effects arising from aspecific drug-target interactions may be predicted and/or clarified at a biomolecular level through direct identification of the off-target proteins on a proteome-wide scale. The whole available human structural proteome can be screened by SPILLO-PBSS in affordable computation time.

Advancing PRECISION MEDICINE

Dose limitation and discontinuation of treatments due to adverse effects may expose patients to major health risks. A clearer drug-target interactions map can be generated by SPILLO-PBSS, aimed at designing safer and more effective therapies, according to individual patient’s variations.

Promoting POLYPHARMACOLOGY

New drug-target interactions responsible for additional positive effects of a therapeutic agent may be successfully identified by SPILLO-PBSS. Polypharmacological therapies able to interfere with multiple targets of the same disease network may then be selected to improve the efficacy of the treatment.

Clarifying THERAPEUTIC EFFECTS

If the mechanism of action of a therapeutic agent is not well-defined or still unknown, a screening of the whole available human structural proteome by SPILLO-PBSS can be crucial to identify the primary target responsible for the reported effects of that molecule.

Facilitating DRUG REPOSITIONING

SPILLO-PBSS may find off-target proteins involved in pathological network other than that to which the primary target belongs, thus providing the opportunity for using known drugs for new indications, maximizing in this way the potential of a drug.

Addressing RARE DISEASES

SPILLO-PBSS can be a valuable resource for neglected- and rare-diseases research in the effort to identify opportunities of drug repositioning, which represents a cheaper and faster alternative to traditional drug discovery.

An overview of SPILLOproject

At SPILLOproject, we specialize in advanced in silico research and consulting services for institutes and companies in the pharmaceutical and biotech sectors. We offer valuable support at various stages of drug R&D. Our technology is adept at addressing many typical challenges in medicinal chemistry, precision medicine, toxicology, and clinical pharmacology.

Our proprietary physics-based in silico technology enables comprehensive and unbiased analyses of the entire structural proteome across various organisms, including Homo sapiens, Mus musculus, and Rattus norvegicus (102,500+ protein 3D structures). Our method stands out in its effectiveness at identifying both target and off-target proteins for any drug, whether marketed or in development. This surpasses the capabilities of other methodologies, as evidenced by multiple experimental validations published in peer-reviewed journals.

In particular, the uniqueness of our technology lies in its ability to identify previously unknown hidden or cryptic binding sites, even those completely closed off by dozens of steric clashes, thus outperforming other structure-based existing methods, such as molecular docking. These capabilities are crucial in preventing financial losses by clarifying or predicting adverse drug reactions (ADR) and/or therapeutic effects at the biomolecular level, and in enhancing profitability through drug repurposing and drug rescue strategies.
