Both PeptiMOL and G4-mtQSAR are built around QSAR-family methods — PeptiMOL applied QSPKR to peptide pharmacokinetics, while G4-mtQSAR extended multi-target QSAR to anti-cancer drug identification.
MOLDRUG AI SYSTEMS SL
Valencia-based computational drug discovery company applying QSAR modeling and machine learning to peptide pharmacokinetics and anti-cancer drug design.
Their core work
MOLDRUG AI SYSTEMS is a Valencia-based private company specializing in computational drug discovery, applying machine learning, chemoinformatics, and quantitative structure-activity modeling to accelerate pharmaceutical research. Their core work involves building predictive models that link molecular structure to pharmacological behavior — specifically how drug candidates are absorbed, distributed, metabolized, and excreted. They have hosted MSCA Individual Fellows working on two distinct challenges: predicting the pharmacokinetics of therapeutic peptides, and identifying new anti-cancer compounds by computationally targeting G-quadruplex DNA structures through multi-target QSAR approaches. Their business model appears to be providing research infrastructure and scientific leadership to attract and host high-caliber individual researchers funded by EU fellowships.
What they specialise in
Drug discovery is the explicit application domain across both projects, using computational simulations and chemoinformatics tools to reduce reliance on wet-lab experimentation.
PeptiMOL (2020–2022) focused specifically on modeling the pharmacokinetic profiles of therapeutic peptides, a technically demanding area where peptide chemical space differs substantially from small molecules.
G4-mtQSAR (2021–2023) introduced machine learning and computational simulations targeting G-quadruplex DNA structures, representing a more data-driven direction compared to the earlier chemoinformatics-only work.
How they've shifted over time
Their two-project trajectory shows a clear methodological shift: the earlier PeptiMOL project was grounded in classical chemoinformatics — QSPKR modeling, computational chemistry, pharmacokinetics — applied to the specialized challenge of therapeutic peptides. The later G4-mtQSAR project moved toward machine learning and multi-target computational approaches, with cancer as the disease focus and G-quadruplex DNA as a specific molecular target. In short, they moved from pharmacokinetics modeling toward AI-driven multi-target drug identification, with oncology emerging as a strategic application area.
They are moving from classical chemoinformatics toward machine learning-integrated, multi-target computational approaches in oncology — suggesting future projects will likely sit at the intersection of AI and precision cancer pharmacology.
How they like to work
MOLDRUG AI SYSTEMS has operated exclusively as a coordinator and host institution under the MSCA Individual Fellowships scheme, which by design does not involve consortia — a fellow joins the host, and the host guides the research. This means their "collaboration" record reflects zero formal consortium partners, not isolation: they attract individual researchers to work within their computational infrastructure. For potential partners, this signals an organization comfortable leading scientific direction but with limited experience navigating large multi-partner EU project management.
Their formal H2020 network consists solely of the MSCA fellows they hosted — no consortium partners and no cross-border institutional collaborations are recorded. As a Valencia-based entity operating under fellowship-only funding, their documented European reach is currently minimal.
What sets them apart
MOLDRUG AI SYSTEMS occupies a specific niche: a private company — not a university or public research institute — that successfully competes for and hosts MSCA Individual Fellows, positioning itself as a credible research environment for top computational chemists. This is unusual; most MSCA-IF hosts are academic institutions, making MOLDRUG a rare private-sector bridge between academic-grade computational drug discovery and commercial application. For consortium builders, they bring focused AI/QSAR expertise without the overhead of a large academic partner, and their cancer and peptide work spans two growing pharmaceutical markets.
Highlights from their portfolio
- G4-mtQSARThe larger of the two projects (€172,932) and the more methodologically advanced — combining multi-target QSAR, machine learning, and G-quadruplex targeting represents a convergence of AI and structural biology that is highly relevant to current oncology drug discovery pipelines.
- PeptiMOLTherapeutic peptides are a fast-growing pharmaceutical class whose pharmacokinetics are notoriously hard to predict; building QSPKR models for this space is both technically difficult and commercially valuable, making this project a strong differentiator.
