It is well-selected from Novel Bioactive Compound Library (D7800), from which 1-15 compounds with the highest scores (activity value, pharmacological properties, structure-diversity, etc.) were chosen.

It is supposed to help generate a higher hit rate, and is a powerful compound library for drug discovery and target identification.
