Compound Library
The DDRC curates and annotates a small molecule library containing 485,000 natural products, low molecular weight screening compounds, pharmacologically active compounds, clinically used compounds and compound fragments.
The Fisher Drug Discovery Compound Screening Library comprises nearly 500,000 drug-like compounds, meticulously chosen from reputable commercial vendors based on their favorable biophysical drug-like attributes and overall diversity. The challenge lies in striking a balance between these two aspects, as the properties necessary for a drug lead compound inherently limit the potential diversity within a chemical compound set. Nonetheless, the efficacy of high-throughput screening hinges on the presence of random and varied compound arrays. To navigate this, we employ a range of algorithms rooted in clustering, diversity analysis and molecular property calculations. Additionally, we factor in assessments of undesirable features to guide our compound selection process.
