Prestwick Chemical

What Prestwick Chemical does

Prestwick Chemical SAS is a French specialty chemical company founded in 1999 that designs, curates, and sells high-quality screening libraries for early-stage drug discovery. The company operates as a fully integrated sub-brand of Laboratoire Greenpharma, a life-science chemistry R&D provider focused on natural substances, and offers ten specialized chemical libraries headlined by the Prestwick Chemical Library® (1760 drugs, mainly FDA-approved). Adjacent products include the Prestwick Drug-Fragment Library (1456 fragments, 56% exclusive to Prestwick with >80% of recent approved drugs containing at least one Prestwick fragment), and disease- or modality-focused collections spanning oncology (Oncombo), CNS penetration, GPCR, peptidic macrocycles, C. elegans phenotypic screening, phytochemicals, original molecules, and ligand discovery (LIGENDO). Each library is delivered with 95%+ purity verified by NMR and LC/MS, experimental solubility data, and a guaranteed resupply commitment of up to 100 mg per compound.

The business operates a sales-led go-to-market model via direct website sales supported by three regional contacts covering Europe & North America, Japan, and South Korea. Revenue is generated through three streams: one-time licensing of pre-defined screening libraries in DMSO or dry format, custom synthesis services (milligram to gram scale) executed through Laboratoire Greenpharma's analytical platform (NMR, LC/MS, HRMS, HPLC), and transactional resupply plus analoging services that provide Structure-Activity Relationship (SAR) data for hit optimization. Pricing is quote-based and not publicly disclosed.

Prestwick serves a horizontally segmented customer base of pharmaceutical companies, biotechnology firms, and academic/research institutions engaged in high-throughput screening, fragment-based drug discovery, drug repurposing, phenotypic screening, and hit-to-lead optimization. Marketing is concentrated in scientific conference participation (RICT 2024, JCBF2024), the company website, LinkedIn, and the 400+ peer-reviewed publications that have cited the Prestwick Chemical Library since 1999 — a publication footprint that functions as both scientific validation and earned-media distribution.
