01. EXPLORE

Unlock nature's chemistry

Expand the frontiers of therapeutic chemistry

Learn More

We are overturning a stone in natural product drug discovery—capturing biology that has been missed, as it exists in nature.

Our goal is to access and unlock the value of a remarkable chemical space that conventional discovery has largely overlooked.

Natural chemistry is shaped by evolution, ecology, and biological competition. While conventional natural product discovery has focused on a relatively narrow range of cultured microorganisms, we pursue chemistry wherever biology creates it—across underrepresented organisms, complex ecological interactions, and wild environments where unique metabolites emerge in response to natural selection.

Our proprietary fungal collection, sourced from the forests of Kapoose Creek, British Columbia is one example of this philosophy, providing access to biology and natural chemistry rarely represented in conventional discovery libraries. We explored fungi from fruiting bodies, animals, insects & plants, where community interactions drive the production of unique bioactive chemistry with increased relevance to human physiology. The collection is rich in exotic species, with ~2/3 of strains having no match in any public database.

Our exploration strategy integrates newly acquired natural chemistry with existing resources, continuously expanding the foundation for therapeutic discovery. From remote field expeditions to strategic partnerships with industry, academia and communities, we are systematically broadening the chemical diversity available to the unEarth Rx Platform, providing an ever-growing source of biologically relevant starting points for new medicines.

02. DISCOVER

Generate biological intelligence

Integrate deep, multi-modal biological evidence to reveal therapeutic opportunities

Learn More

Natural chemistry becomes valuable when its biological potential is understood. Our Discover platform combines artificial intelligence with multi-modal biology to reveal how natural molecules interact with living systems, uncovering therapeutic opportunities that would otherwise remain hidden.

Rather than relying on a single experimental readout, we integrate complementary biological evidence from metabolomics, phenomics, transcriptomics, proteomics, and other high-content assays to build a comprehensive understanding of molecular function. Each layer provides a different perspective on biology, while together they generate a richer and more reliable picture of therapeutic potential.

By combining these complementary layers of biological evidence with machine learning, we create Biological Intelligence — a unified understanding of how natural chemistry interacts with biology. This enables us to confidently identify, prioritize, and advance the most promising therapeutic opportunities,

03. ADVANCE

Engineer for medicine

Optimize in unique chemical space, establish strategies for scaled production, and progress de-risked drug candidates forward with confidence.

Learn More

The best medicines don’t begin as perfect drug candidates, they begin with extraordinary chemistry. Our Advance platform engineers that chemistry for medicine, transforming biologically prioritized natural molecules into optimized, scalable drug candidates through an integrated approach to medicinal chemistry, process development, and scalable production.

Unlike conventional drug discovery, which often begins with synthetic screening hits of uncertain biological relevance, we begin in privileged chemical space—natural chemistry refined through billions of years of evolution to shape biology. This provides a uniquely informed foundation for medicinal chemistry, enabling us to optimize potency, selectivity, pharmacokinetic properties, and developability while preserving the biological features that make these molecules compelling therapeutic starting points.

We take a pragmatic approach to optimization and scale, combining medicinal chemistry, semi-synthesis, total synthesis, fermentation, and proprietary synthetic biology to establish the most effective development and production strategy for each program. For rare or inaccessible chemistry, our proprietary expression technologies unlock metabolites that have historically been beyond reach, enabling efficient production of both natural products and their optimized derivatives.

Together, these capabilities bridge the gap between natural chemistry and drug development, engineering nature’s most promising discoveries into differentiated drug candidates ready for preclinical advancement.
